An enterprise connects a private data center to a public cloud using an IPsec tunnel. The tunnel shows as established, but applications experience intermittent packet loss when large packets are transmitted. Which issue should be investigated first?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> BGP local preference<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF router ID<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> BGP MED<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Path MTU and IPsec overhead<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Path MTU and IPsec overhead<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">IPsec encapsulation adds overhead to packets, reducing the effective payload size that can traverse the tunnel without fragmentation. If large packets are intermittently lost while smaller packets work normally, MTU-related problems are a strong possibility. The administrator should verify the effective path MTU, fragmentation behavior, and whether TCP MSS adjustment is required. BGP local preference, OSPF router ID, and BGP MED affect routing decisions rather than the ability of large packets to traverse an encrypted tunnel. MTU problems are particularly important when cloud connectivity uses overlays, tunnels, or other encapsulation mechanisms that further reduce the usable packet size.<\/span><\/p>\n<p><b>Question 282. A company uses two cloud connections from an enterprise network and wants traffic to prefer one connection while retaining the second connection as an alternative. Which BGP attribute is commonly used within the local autonomous system to influence outbound path selection?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> MED<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Local preference<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Origin code<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Community<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Local preference<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">BGP local preference is commonly used to influence outbound path selection within an autonomous system. A higher local-preference value is preferred when selecting among applicable BGP routes, allowing an organization to designate one cloud connection as the preferred exit while retaining another as a backup. MED is generally used to influence how neighboring autonomous systems enter the local AS, while origin code is part of BGP route attributes but is considered later in path selection. Communities can be used to classify or signal routing policy but do not inherently provide the same direct local outbound preference function.<\/span><\/p>\n<p><b>Question 283. An organization deploys redundant cloud connectivity from two different enterprise edge routers. The design requirement is that loss of one physical connection should not isolate the site from the cloud. Which design principle directly addresses this requirement?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Redundancy and resiliency<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Increasing DNS TTL values<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Using a single shared circuit<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disabling dynamic routing<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. Redundancy and resiliency<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Redundancy and resiliency are fundamental cloud-connectivity design principles when continuous connectivity is required despite component failures. Using multiple connections, diverse paths, or redundant edge devices can allow traffic to continue when a circuit, interface, router, or provider path fails. Increasing DNS TTL values does not provide network-path redundancy. A single shared circuit introduces a potential single point of failure, while disabling dynamic routing can make convergence and failover more difficult. The actual design should also consider physical diversity, provider diversity, routing convergence, and application requirements when determining how much redundancy is necessary.<\/span><\/p>\n<p><b>Question 284. A network engineer configures BGP between an enterprise router and a cloud virtual router. The enterprise receives cloud prefixes, but the cloud side does not receive the enterprise&#8217;s internal prefixes. Which verification is most directly relevant?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF hello interval<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> IPsec encryption algorithm<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> BGP advertised routes toward the cloud neighbor<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> NTP synchronization<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. BGP advertised routes toward the cloud neighbor<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If the enterprise receives routes from the cloud but the cloud does not receive the enterprise&#8217;s prefixes, the administrator should verify what routes the enterprise BGP speaker is advertising to the cloud neighbor. The BGP advertised-routes view can reveal whether the required prefixes are being sent and whether outbound filtering is preventing them from being advertised. OSPF timers, IPsec encryption algorithms, and NTP synchronization do not directly verify the BGP prefixes being sent to the cloud peer. Additional checks should include route availability in the local routing table, outbound route policies, prefix lists, and the BGP neighbor state.<\/span><\/p>\n<p><b>Question 285. A cloud connectivity design must support latency-sensitive voice traffic while sharing the WAN connection with bulk data transfers. Which requirement should receive specific consideration during the design phase?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS zone-transfer frequency<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> QoS and traffic-class requirements<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> BGP router ID uniqueness only<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Increasing the number of VLAN names<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. QoS and traffic-class requirements<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Latency-sensitive applications such as voice require predictable treatment of packets during congestion. Cloud connectivity design should therefore consider QoS requirements, traffic classification, bandwidth allocation, queueing behavior, latency, jitter, and packet-loss objectives. Simply increasing VLAN names or focusing only on BGP router IDs does not address application performance under congestion. DNS zone-transfer frequency is also unrelated to WAN packet scheduling. The design should identify critical traffic classes and determine whether the available connectivity and provider service can meet the required performance objectives during normal operation and expected peak-demand conditions.<\/span><\/p>\n<p><b>Question 286. An administrator wants to verify whether an IPsec tunnel is actually carrying encrypted traffic rather than merely being established. Which information provides the most direct evidence?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF database contents<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> BGP router ID<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS cache entries<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> IPsec packet and security-association counters<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. IPsec packet and security-association counters<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An established IPsec security association confirms that the peers have negotiated the required security parameters, but it does not by itself prove that application traffic is successfully traversing the tunnel. IPsec packet and security-association counters provide direct evidence that packets are being encrypted and decrypted. If counters remain unchanged while users generate traffic, the administrator should investigate routing, traffic selectors, firewall policies, or other forwarding problems. OSPF database information, BGP router IDs, and DNS cache entries may help diagnose other layers of connectivity but do not directly demonstrate that encrypted traffic is flowing through the IPsec security association.<\/span><\/p>\n<p><b>Question 287. A company uses BGP to exchange routes between its enterprise network and a cloud provider. The engineer wants to prevent unexpected cloud prefixes from entering the enterprise routing table. Which mechanism should be applied to the inbound BGP updates?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Inbound prefix filtering<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS forwarding<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> TCP MSS rewriting<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF authentication<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. TCP MSS rewriting<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">TCP MSS rewriting does not filter routing information; it adjusts the maximum TCP segment size to accommodate path MTU constraints. To prevent unexpected cloud prefixes from being accepted into the enterprise routing table, the appropriate control is an inbound BGP policy such as a prefix list or route map. Such filtering can explicitly permit expected prefixes and deny unwanted routes. DNS forwarding affects name resolution, while OSPF authentication applies to OSPF neighbor relationships. Careful inbound filtering is especially important when cloud providers advertise multiple networks or when the enterprise wants strict control over which cloud routes are installed.<\/span><\/p>\n<p><b>Question 288. An enterprise uses Cisco Catalyst SD-WAN to provide cloud connectivity. The organization wants applications to use an appropriate cloud path based on application-aware policy and measured network conditions. Which capability best supports this requirement?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Static DNS entries<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Local ARP inspection only<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Application-aware SD-WAN policy<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Disabling centralized policy<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Application-aware SD-WAN policy<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Application-aware SD-WAN policies can use application identification and network-performance information to influence path selection and traffic treatment. This is useful when cloud applications have different latency, loss, jitter, bandwidth, or availability requirements. Rather than treating every application identically, the SD-WAN fabric can apply policy based on application characteristics and measured path performance. Static DNS entries and ARP inspection do not provide this application-aware path-selection capability. Disabling centralized policy would also remove an important mechanism for consistently applying application and routing requirements across the SD-WAN environment.<\/span><\/p>\n<p><b>Question 289. A cloud-connected enterprise has two possible routes to the same destination. One route is learned through eBGP and another through OSPF. Assuming normal default administrative distances and otherwise applicable routes, which route is preferred by the Cisco router?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The OSPF route because OSPF always overrides BGP<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Both routes are installed with equal preference<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The eBGP route because its default administrative distance is lower<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The route with the higher IP address<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. The eBGP route because its default administrative distance is lower<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Cisco routers use administrative distance to compare routes learned from different routing protocols. By default, eBGP has an administrative distance of 20, while OSPF has an administrative distance of 110. Therefore, when otherwise comparable routes to the same destination are learned through eBGP and OSPF, the eBGP route is preferred because it has the lower administrative distance. This comparison occurs before protocol-specific attributes are used within a routing protocol. Engineers should verify whether administrative-distance values have been manually changed, because customized values can alter the normal route-selection behavior.<\/span><\/p>\n<p><b>Question 290. A cloud application requires private connectivity with predictable performance and specific contractual availability requirements. Which design consideration is most important when selecting the connectivity service?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> SLA requirements<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Number of DNS records<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF process ID<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Hostname length<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. SLA requirements<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Service-level agreement requirements should be evaluated when a cloud application requires predictable availability or performance. An SLA can define measurable service commitments such as availability, latency, packet loss, restoration objectives, or other provider responsibilities, depending on the service. These requirements should be compared with the application&#8217;s business and technical needs before selecting a connectivity model. DNS records, OSPF process IDs, and hostname length do not establish whether the provider&#8217;s connectivity service meets contractual performance or availability requirements. The design should also consider redundancy, bandwidth, security, compliance, and failure scenarios alongside SLA requirements.<\/span><\/p>\n<p><b>Question 291. A network engineer observes that a cloud BGP session remains established, but a newly created enterprise subnet is not reachable from the cloud. The subnet exists in the local routing table. What should be checked next?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The cloud provider&#8217;s DNS cache<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The BGP routes advertised toward the cloud peer<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The router&#8217;s console baud rate<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The NTP stratum<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. The BGP routes advertised toward the cloud peer<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A prefix existing in the local routing table does not automatically mean that BGP is advertising it to the cloud peer. The engineer should verify the routes being advertised toward that neighbor and check for outbound prefix lists, route maps, or other policies that may prevent the subnet from being exported. If the prefix is advertised, the next steps include checking whether the cloud side accepts the route and whether the return path exists. DNS cache, console baud rate, and NTP stratum do not directly explain why a newly created routing prefix is absent from the cloud routing domain.<\/span><\/p>\n<p><b>Question 292. A company routes Internet-bound traffic from a branch through a centralized data center before sending it to the Internet. Which traffic-flow model is being used?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Local Internet breakout<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> East-west traffic<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Internet backhaul<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Direct cloud peering only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. Internet backhaul<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Internet backhaul occurs when traffic from a remote site is transported through a centralized location before reaching the public Internet. Organizations may use this design when centralized security inspection, policy enforcement, logging, or Internet access controls are required. Local Internet breakout would instead allow the branch to access the Internet directly from its local connectivity point. East-west traffic generally describes traffic between internal workloads, sites, or segments rather than traffic flowing toward the public Internet. The chosen architecture should account for latency, bandwidth consumption, security inspection capacity, resiliency, and regulatory requirements.<\/span><\/p>\n<p><b>Question 293. An enterprise wants cloud workloads in separate network segments to communicate while ensuring that security controls are enforced between those segments. Which traffic direction and design concern are most relevant?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> East-west traffic and inter-segment security policy<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> North-south traffic and DNS caching only<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Internet traffic and BGP router ID selection<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> NTP traffic and OSPF hello timers<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. East-west traffic and inter-segment security policy<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Traffic between workloads or network segments inside a cloud or enterprise environment is commonly considered east-west traffic. When those segments have different trust levels or security requirements, communication should be controlled by explicit security policies, segmentation mechanisms, or firewalls. North-south traffic generally describes traffic entering or leaving the environment. BGP router IDs, DNS caching, NTP traffic, and OSPF hello timers do not directly provide the required inter-segment security control. A proper design should define which east-west flows are permitted and ensure that the enforcement point can handle the expected throughput and connection volume.<\/span><\/p>\n<p><b>Question 294. A cloud IPsec tunnel is operational, but packets from the enterprise LAN are not encrypted. The administrator verifies that the tunnel negotiation succeeded. Which configuration should be examined for a policy-based IPsec design?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> BGP local preference<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF router priority<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Traffic selectors or crypto ACLs<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS search domains<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Traffic selectors or crypto ACLs<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Successful IPsec negotiation does not guarantee that the desired data traffic matches the policy used to protect packets. In a policy-based IPsec implementation, traffic selectors or crypto ACLs identify which source and destination traffic should be encrypted. If the enterprise LAN subnet is missing, incorrectly defined, or mismatched with the peer&#8217;s selectors, packets may bypass the tunnel or fail to establish the expected security association for that traffic. BGP local preference, OSPF router priority, and DNS search domains do not determine which packets match the IPsec encryption policy.<\/span><\/p>\n<p><b>Question 295. An organization evaluates a cloud connectivity service that uses shared infrastructure. Which concern should be specifically evaluated when comparing it with a dedicated connectivity option?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Router hostname capitalization<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Predictability of performance and contention<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> OSPF area numbering format<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Number of DNS suffixes<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Predictability of performance and contention<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Shared connectivity can introduce contention because multiple customers or services may use common underlying resources. When comparing shared and dedicated connectivity, the organization should evaluate bandwidth guarantees, congestion behavior, latency, performance predictability, SLA commitments, and provider architecture. A dedicated service may provide different characteristics, but the appropriate choice depends on documented business, technical, security, and cost requirements. Router hostname capitalization, OSPF area numbering, and DNS suffix counts do not meaningfully determine the performance characteristics of the connectivity service.<\/span><\/p>\n<p><b>Question 296. A network engineer wants to determine whether a route learned from a cloud BGP neighbor is being rejected by an inbound routing policy. Which information is most useful?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The local interface description<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The DNS resolver address<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The BGP received-routes information and inbound policy<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The IPsec encryption key length only<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. The BGP received-routes information and inbound policy<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">When a route is expected from a BGP neighbor but does not appear in the routing table, the engineer should examine the routes received from that neighbor and the inbound routing policy applied to the session. This can reveal whether the prefix was received but rejected by a prefix list, route map, policy statement, or other filtering mechanism. An interface description and DNS resolver address do not show BGP policy behavior. IPsec encryption parameters may be relevant to tunnel troubleshooting, but they do not directly identify whether an inbound BGP route was filtered.<\/span><\/p>\n<p><b>Question 297. A cloud provider requires the enterprise to establish connectivity using BGP over redundant IPsec tunnels. What is the primary operational benefit of using dynamic routing in this design?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Automatic route adaptation when path availability changes<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Elimination of all encryption overhead<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Removal of all security policies<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Prevention of every possible packet loss event<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Prevention of every possible packet loss event<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Dynamic routing can detect changes in route availability and select an alternative path when the preferred path becomes unavailable, depending on the routing design and failure-detection mechanisms. However, it does not eliminate encryption overhead, remove security policies, or prevent every possible packet-loss event. In a design using redundant IPsec tunnels, BGP can provide dynamic route exchange and convergence between available paths. The actual convergence behavior depends on timers, tracking, tunnel state detection, route policies, and the specific architecture. Operational testing should verify both normal routing and expected failure scenarios.<\/span><\/p>\n<p><b>Question 298. An SD-WAN deployment uses centralized security inspection for Internet-bound traffic. What is an important design consideration for the centralized inspection point?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> The number of local DNS aliases<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> Its ability to handle expected traffic volume and failure conditions<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The BGP origin code of every route<\/span><\/li>\n<li><b><\/b><span style=\"font-weight: 400;\"> The OSPF process ID length<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. Its ability to handle expected traffic volume and failure conditions<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Centralized Internet security inspection can become a bottleneck or single point of failure if its capacity and resiliency are not designed appropriately. The inspection infrastructure should be sized for expected throughput, concurrent sessions, peak demand, encrypted traffic requirements, and growth. Redundancy and failover behavior should also be evaluated so that a device or path failure does not unexpectedly interrupt Internet access. DNS aliases, BGP origin codes, and OSPF process ID length do not directly determine the inspection point&#8217;s ability to process traffic. Capacity planning should include realistic peak and failure scenarios.<\/span><\/p>\n<p><b>Question 299. An administrator verifies that an SD-WAN policy is sending application traffic over the intended cloud path, but users still experience poor application performance.

Latency, jitter, and packet loss<\/b><\/p>\n<p><b>Explanation :-<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Latency, jitter, and packet loss are key indicators of network-path quality for many applications. An SD-WAN policy may correctly select a path according to configured rules, but the path can still exhibit performance characteristics that affect application behavior. Measuring these metrics helps determine whether the selected connection meets the application&#8217;s requirements. For voice and interactive applications, jitter and packet loss can be particularly significant, while latency affects responsiveness. Hostnames, VLAN descriptions, and DNS suffix lengths do not directly measure the quality of the underlying network path.<\/span><\/p>\n<p><b>Question 300.

By intentionally disabling an active path, the engineer can verify whether routing detects the failure, selects the intended alternate path, and restores application reachability within the required timeframe. The test should also measure convergence, packet loss, application impact, and recovery behavior. Changing a hostname, removing all BGP policies, or changing an OSPF process ID does not represent a controlled validation of the intended redundancy mechanism.
