Question 81. An enterprise is designing connectivity to a public cloud and requires a private connection with predictable performance and a defined provider SLA. Which connectivity model should be evaluated?<\/b><\/p>\n

    \n
  1. <\/b> Public Internet with unrestricted routing<\/span><\/li>\n
  2. <\/b> Client-based remote-access VPN<\/span><\/li>\n
  3. <\/b> DNS-based application forwarding<\/span><\/li>\n
  4. <\/b> Dedicated cloud connectivity<\/span><\/li>\n<\/ol>\n

    Correct Answer: 4. Dedicated cloud connectivity<\/b><\/p>\n

    Explanation :-<\/b><\/p>\n

    Dedicated cloud connectivity provides a private interconnection between an enterprise network and a cloud provider through supported connectivity services. It is appropriate when requirements include predictable performance, defined service characteristics, and avoidance of the public Internet. The architect should still evaluate bandwidth, resiliency, routing, QoS, geographic availability, and provider SLA commitments. A client-based VPN is generally intended for individual users rather than primary enterprise-to-cloud connectivity. Public Internet connectivity can be secure when IPsec is used, but its transport characteristics differ from those of dedicated connectivity.<\/span><\/p>\n

    Question 82. An administrator is configuring a cloud VPN connection on Cisco IOS XE and needs to establish the security association negotiation process. Which protocol should be configured?<\/b><\/p>\n

      \n
    1. <\/b> IKE<\/span><\/li>\n
    2. <\/b> BGP<\/span><\/li>\n
    3. <\/b> OSPF<\/span><\/li>\n
    4. <\/b> DHCP<\/span><\/li>\n<\/ol>\n

      Correct Answer: 1. IKE<\/b><\/p>\n

      Explanation :-<\/b><\/p>\n

      IKE, including IKEv2, is responsible for negotiating security associations used by IPsec. It handles peer authentication and negotiation of cryptographic and security parameters before protected IPsec traffic is exchanged. BGP and OSPF are routing protocols and may operate across an appropriate secure connectivity architecture, but they do not negotiate IPsec security associations. DHCP provides address-assignment services and is unrelated to VPN security negotiation. Correct IKE configuration is therefore a fundamental requirement when establishing an IPsec-based cloud VPN.<\/span><\/p>\n

      Question 83. A company wants to advertise only its production subnets toward a cloud provider using BGP. Which mechanism should be used to control the advertised prefixes?<\/b><\/p>\n

        \n
      1. <\/b> DHCP relay<\/span><\/li>\n
      2. <\/b> CDP<\/span><\/li>\n
      3. <\/b> BGP route filtering<\/span><\/li>\n
      4. <\/b> LLDP<\/span><\/li>\n<\/ol>\n

        Correct Answer: 3. BGP route filtering<\/b><\/p>\n

        Explanation :-<\/b><\/p>\n

        BGP route filtering provides control over which prefixes are advertised to or accepted from a BGP neighbor. An enterprise can use prefix lists, route maps, and related policy mechanisms to ensure that only approved production networks are advertised to the cloud provider. This prevents accidental propagation of management, development, or unrelated internal routes. CDP and LLDP provide neighbor information, while DHCP relay forwards address-assignment messages. Neither provides the required control over BGP route advertisements.<\/span><\/p>\n

        Question 84. A business-critical application requires uninterrupted cloud access if a single connectivity circuit fails. Which design feature should be incorporated?<\/b><\/p>\n

          \n
        1. <\/b> Single-homed connectivity<\/span><\/li>\n
        2. <\/b> Redundant connectivity paths<\/span><\/li>\n
        3. <\/b> One static default route<\/span><\/li>\n
        4. <\/b> Centralized DNS only<\/span><\/li>\n<\/ol>\n

          Correct Answer: 2. Redundant connectivity paths<\/b><\/p>\n

          Explanation :-<\/b><\/p>\n

          Redundant connectivity paths provide alternate forwarding options when a primary circuit becomes unavailable. Depending on the architecture, redundancy can involve multiple circuits, providers, cloud attachments, routers, or tunnels. The routing design must also support failure detection and convergence so that the alternate path becomes usable when required. A single-homed architecture creates a single point of failure, while DNS alone does not provide network-path redundancy. The architect should also verify that the surviving connection has sufficient capacity during a failure condition.<\/span><\/p>\n

          Question 85. A cloud-connected router learns a route through BGP, but a different route to the same destination is already installed. Which factor determines whether the BGP route becomes the active route?<\/b><\/p>\n

            \n
          1. <\/b> Route-selection criteria such as administrative distance and metrics<\/span><\/li>\n
          2. <\/b> DNS server priority<\/span><\/li>\n
          3. <\/b> DHCP lease duration<\/span><\/li>\n
          4. <\/b> Interface description length<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1. Route-selection criteria such as administrative distance and metrics<\/b><\/p>\n

            Explanation :-<\/b><\/p>\n

            Cisco IOS XE evaluates multiple routing sources according to route-selection rules. Administrative distance is used to compare routes from different routing protocols, while metrics and other attributes are considered within the appropriate routing protocol. Therefore, receiving a BGP route does not automatically make it the active forwarding path. The engineer should inspect the competing route, administrative distances, BGP attributes, next-hop reachability, and policy. DNS, DHCP, and interface descriptions do not determine which routing entry is installed for forwarding.<\/span><\/p>\n

            Question 86. An organization wants branch users to access SaaS applications directly instead of backhauling all SaaS traffic through a central data center. Which Cisco Catalyst SD-WAN capability is relevant?<\/b><\/p>\n

              \n
            1. <\/b> OnRamp to SaaS<\/span><\/li>\n
            2. <\/b> DHCP snooping<\/span><\/li>\n
            3. <\/b> STP root selection<\/span><\/li>\n
            4. <\/b> CDP discovery<\/span><\/li>\n<\/ol>\n

              Correct Answer: 4. OnRamp to SaaS<\/b><\/p>\n

              Explanation :-<\/b><\/p>\n

              Cisco Catalyst SD-WAN OnRamp to SaaS provides capabilities for optimized connectivity between the SD-WAN environment and SaaS applications. It can help identify SaaS destinations and use appropriate connectivity paths according to network conditions and configured policies. This can reduce unnecessary backhaul and improve application access from branch locations. DHCP snooping, STP, and CDP address different networking functions and do not provide SaaS-specific path optimization. The final implementation should also account for security, compliance, and application-performance requirements.<\/span><\/p>\n

              Question 87. An IPsec cloud tunnel is established, but large application packets are dropped while small packets succeed. Which problem should be investigated first?<\/b><\/p>\n

                \n
              1. <\/b> BGP router ID<\/span><\/li>\n
              2. <\/b> MTU and fragmentation behavior<\/span><\/li>\n
              3. <\/b> DNS zone transfer<\/span><\/li>\n
              4. <\/b> DHCP authorization<\/span><\/li>\n<\/ol>\n

                Correct Answer: 2. MTU and fragmentation behavior<\/b><\/p>\n

                Explanation :-<\/b><\/p>\n

                Tunnel encapsulation adds overhead to packets, reducing the effective payload size that can traverse the underlying path without fragmentation. If the effective MTU is exceeded and fragmentation or Path MTU Discovery does not work correctly, larger packets can fail while smaller packets continue to pass. Troubleshooting should examine tunnel and interface MTU settings, MSS behavior, fragmentation, and relevant ICMP messages. BGP router IDs, DNS zone transfers, and DHCP authorization do not directly address a packet-size-dependent IPsec connectivity problem.<\/span><\/p>\n

                Question 88. A cloud provider requires an enterprise to accept only approved routes from its BGP neighbor. Which configuration is most appropriate?<\/b><\/p>\n

                  \n
                1. <\/b> Outbound NAT<\/span><\/li>\n
                2. <\/b> Inbound BGP prefix filtering<\/span><\/li>\n
                3. <\/b> DHCP relay<\/span><\/li>\n
                4. <\/b> DNS forwarding<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 3. Inbound BGP prefix filtering<\/b><\/p>\n

                  Explanation :-<\/b><\/p>\n

                  Inbound BGP prefix filtering controls which routes are accepted from a neighbor. Prefix lists or other routing-policy mechanisms can identify approved cloud prefixes and reject unexpected advertisements. This is important for maintaining routing-table stability and preventing unintended route propagation. Outbound NAT changes address information and does not filter BGP routes. DHCP relay and DNS forwarding serve address-assignment and name-resolution functions. When implementing inbound filtering, the administrator should verify the intended prefixes and policy logic carefully to avoid accidentally blocking required cloud routes.<\/span><\/p>\n

                  Question 89. A company wants an SD-WAN policy to choose a WAN path based on latency, jitter, and packet loss for a cloud application. Which capability is being used?<\/b><\/p>\n

                    \n
                  1. <\/b> Performance-based path selection<\/span><\/li>\n
                  2. <\/b> Static VLAN assignment<\/span><\/li>\n
                  3. <\/b> DHCP address allocation<\/span><\/li>\n
                  4. <\/b> MAC address learning<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 4. Performance-based path selection<\/b><\/p>\n

                    Explanation :-<\/b><\/p>\n

                    Performance-based path selection uses measured characteristics of available WAN paths to determine whether they satisfy application requirements. Latency, jitter, and packet loss are important performance indicators for applications such as voice, video, and interactive cloud services. Cisco Catalyst SD-WAN can use application-aware policies and performance information to influence path selection. VLAN assignment, DHCP, and MAC learning perform different network functions and do not dynamically evaluate WAN performance for application forwarding.<\/span><\/p>\n

                    Question 90. An enterprise needs to connect its data center to a cloud environment through an encrypted tunnel over the public Internet. Which architecture best fits this requirement?<\/b><\/p>\n

                      \n
                    1. <\/b> Unencrypted GRE<\/span><\/li>\n
                    2. <\/b> IPsec-based site-to-cloud VPN<\/span><\/li>\n
                    3. <\/b> Plain Layer 2 extension<\/span><\/li>\n
                    4. <\/b> DHCP relay across the Internet<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 1. IPsec-based site-to-cloud VPN<\/b><\/p>\n

                      Explanation :-<\/b><\/p>\n

                      An IPsec-based site-to-cloud VPN provides encrypted connectivity over the public Internet. IPsec can provide confidentiality, integrity, and peer authentication according to the configured security parameters. The VPN can then carry appropriate routed traffic between the enterprise and cloud environment. Plain GRE does not inherently encrypt traffic, while DHCP relay and Layer 2 extension do not provide the required secure IP tunnel. The design should also consider routing, tunnel selectors, MTU, redundancy, and the cloud provider’s supported VPN architecture.<\/span><\/p>\n

                      Question 91. A network architect is evaluating whether a cloud connection can carry peak traffic while one redundant link is unavailable. Which design activity is required?<\/b><\/p>\n

                        \n
                      1. <\/b> Capacity planning under failure conditions<\/span><\/li>\n
                      2. <\/b> DNS cache optimization only<\/span><\/li>\n
                      3. <\/b> Device hostname standardization<\/span><\/li>\n
                      4. <\/b> Disable QoS<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 2. Capacity planning under failure conditions<\/b><\/p>\n

                        Explanation :-<\/b><\/p>\n

                        Cloud connectivity capacity must be evaluated not only during normal operation but also during failure scenarios. If one redundant link becomes unavailable, the remaining path may need to carry substantially more traffic. The architect should determine whether available bandwidth, QoS policies, and application requirements can be satisfied during the degraded state. This helps prevent a design that appears redundant but becomes congested whenever failover occurs. DNS caching and hostname standards do not provide capacity assurance, and QoS should be designed according to application requirements rather than disabled arbitrarily.<\/span><\/p>\n

                        Question 92. An engineer needs to verify whether cloud routes received through BGP are actually installed as usable routes. Which two areas should be correlated?<\/b><\/p>\n

                          \n
                        1. <\/b> DNS records and DHCP leases<\/span><\/li>\n
                        2. <\/b> BGP routing information and the routing table<\/span><\/li>\n
                        3. <\/b> CDP neighbors and LLDP neighbors<\/span><\/li>\n
                        4. <\/b> NTP status and system logs<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 2. BGP routing information and the routing table<\/b><\/p>\n

                          Explanation :-<\/b><\/p>\n

                          BGP information shows what routes are learned and the attributes associated with them, while the routing table shows which routes have ultimately been selected for forwarding. Comparing the two helps identify issues involving route filtering, next-hop reachability, administrative distance, competing routes, or route-policy decisions. A route can be successfully received through BGP without becoming the active routing-table entry. DNS, DHCP, CDP, LLDP, and NTP provide useful services but do not directly verify BGP route installation.<\/span><\/p>\n

                          Question 93. A company wants to minimize unnecessary WAN traffic by allowing selected branch traffic to access Internet-based cloud services locally. Which architectural concept is most relevant?<\/b><\/p>\n

                            \n
                          1. <\/b> Local Internet breakout<\/span><\/li>\n
                          2. <\/b> Centralized backhaul<\/span><\/li>\n
                          3. <\/b> Layer 2 loop prevention<\/span><\/li>\n
                          4. <\/b> DHCP relay<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1. Local Internet breakout<\/b><\/p>\n

                            Explanation :-<\/b><\/p>\n

                            Local Internet breakout allows selected branch traffic destined for Internet-based services, including supported SaaS applications, to exit locally rather than being backhauled through a central enterprise location. This can reduce latency and WAN utilization. However, local breakout must be evaluated against security inspection, compliance, logging, and centralized policy requirements. Centralized backhaul can remain appropriate where security architecture requires it. DHCP relay and Layer 2 loop prevention do not address the WAN forwarding architecture described.<\/span><\/p>\n

                            Question 94. An enterprise needs to exchange selected internal routes with a cloud environment while using BGP. Which design practice helps prevent accidental advertisement of sensitive or unrelated networks?<\/b><\/p>\n

                              \n
                            1. <\/b> Advertise the entire routing table<\/span><\/li>\n
                            2. <\/b> Disable route policies<\/span><\/li>\n
                            3. <\/b> Use explicit prefix filtering and route policy<\/span><\/li>\n
                            4. <\/b> Replace BGP with ARP<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 4. Use explicit prefix filtering and route policy<\/b><\/p>\n

                              Explanation :-<\/b><\/p>\n

                              Explicit prefix filtering and route policy allow an enterprise to define which routes may be advertised to or accepted from a cloud environment. This reduces the risk of accidentally exposing management, development, infrastructure, or other unrelated prefixes. Policies can be implemented using prefix lists, route maps, and other supported BGP mechanisms. Advertising the entire routing table removes this control and can create unnecessary routing exposure. ARP is a local address-resolution mechanism and cannot replace BGP for interdomain route exchange.<\/span><\/p>\n

                              Question 95. A cloud connectivity design must provide different forwarding treatment for voice, business applications, and bulk data. Which technology should be evaluated?<\/b><\/p>\n

                                \n
                              1. <\/b> QoS<\/span><\/li>\n
                              2. <\/b> CDP<\/span><\/li>\n
                              3. <\/b> DNSSEC<\/span><\/li>\n
                              4. <\/b> DHCP snooping<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 3. QoS<\/b><\/p>\n

                                Explanation :-<\/b><\/p>\n

                                QoS allows traffic to be classified and treated according to application requirements. Voice may require low latency and jitter, business applications may need reliable bandwidth, and bulk data may tolerate lower priority. QoS policies can use classification, marking, queuing, shaping, and policing as supported by the platform and network architecture. CDP, DNSSEC, and DHCP snooping perform different functions and do not provide differentiated forwarding treatment. QoS should be designed consistently across relevant WAN and cloud connectivity segments.<\/span><\/p>\n

                                Question 96. A cloud VPN tunnel shows established security associations, but no packets are being encrypted when application traffic is generated. Which area should be checked?<\/b><\/p>\n

                                  \n
                                1. <\/b> The router’s hostname<\/span><\/li>\n
                                2. <\/b> Traffic selectors or the crypto policy matching the application traffic<\/span><\/li>\n
                                3. <\/b> The local monitor resolution<\/span><\/li>\n
                                4. <\/b> The device rack position<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 2. Traffic selectors or the crypto policy matching the application traffic<\/b><\/p>\n

                                  Explanation :-<\/b><\/p>\n

                                  Established IPsec security associations do not guarantee that the intended application packets match the configured protection policy. The engineer should verify local and remote protected networks, crypto ACLs or traffic selectors where applicable, routing, and corresponding cloud-side configuration. If application packets do not match the expected policy, they may be forwarded without entering the IPsec protection process. Tunnel counters can help confirm whether traffic is actually being encrypted. Unrelated device naming or physical placement does not explain the absence of encrypted packet counters.<\/span><\/p>\n

                                  Question 97. An organization wants its cloud connectivity architecture to accommodate additional branches and workloads over the next several years. Which characteristic should be emphasized?<\/b><\/p>\n

                                    \n
                                  1. <\/b> Scalability<\/span><\/li>\n
                                  2. <\/b> Single-path dependency<\/span><\/li>\n
                                  3. <\/b> Manual per-user tunneling<\/span><\/li>\n
                                  4. <\/b> Fixed capacity with no expansion option<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 4. Scalability<\/b><\/p>\n

                                    Explanation :-<\/b><\/p>\n

                                    Scalability allows a connectivity architecture to grow as business requirements, branches, applications, and cloud workloads increase. A scalable design should consider address planning, routing scalability, bandwidth growth, provider capabilities, policy management, redundancy, and operational automation. A design based on fixed capacity or manual per-user tunnels may become difficult to operate as the environment expands. Scalability should be considered alongside availability and security so that growth does not require fundamental redesign of the cloud connectivity architecture.<\/span><\/p>\n

                                    Question 98. An enterprise uses two cloud connectivity paths and wants one path to carry traffic normally while the other becomes active after failure. Which mechanism can implement this preference?<\/b><\/p>\n

                                      \n

                                      Correct Answer: 1. Routing preference and failover policy<\/b><\/p>\n

                                      Explanation :-<\/b><\/p>\n

                                      Routing preference and failover policy can establish an active\/backup forwarding design. Depending on the technology, this may involve BGP attributes, administrative distance, route metrics, SD-WAN policies, or other supported mechanisms. The design must also include reliable failure detection and appropriate convergence. DNS round-robin does not directly determine packet forwarding and may not provide the required network-level failover behavior. DHCP and CDP perform unrelated functions. The architect should also confirm that the backup path has sufficient capacity for the expected failure state.<\/span><\/p>\n

                                      Question 99. During troubleshooting, a cloud application works from the enterprise but not in the return direction. Which issue should be investigated?<\/b><\/p>\n

                                        Correct Answer: 2. Interface description length<\/b><\/p>\n

                                        Explanation :-<\/b><\/p>\n

                                        A one-way communication problem should lead the engineer to investigate the return path, routing, security policy, NAT behavior, and cloud-side forwarding. Interface description length does not normally affect packet forwarding. The correct troubleshooting focus should be on whether the remote environment has a route back to the enterprise source network and whether security controls permit the return traffic. Correlating forwarding information and packet counters in both directions can help isolate the problem efficiently.<\/span><\/p>\n

                                        Question 100. An enterprise is reviewing a cloud connectivity design after repeated outages. The team wants to determine whether the architecture can tolerate failure of a provider, circuit, or cloud attachment. Which design area should be reviewed?<\/b><\/p>\n

                                          Correct Answer: 3. Resiliency and redundancy<\/b><\/p>\n

                                          Explanation :-<\/b><\/p>\n

                                          Resiliency and redundancy determine how effectively a cloud connectivity architecture can continue operating when infrastructure or service components fail. The review should examine independent circuits, providers, cloud attachments, routing convergence, failure detection, capacity during failover, and potential single points of failure. An architecture may contain redundant components but still fail if those components share a common dependency. DNS naming, display settings, and printer connectivity do not determine the resilience of the cloud WAN architecture.<\/span><\/p>\n
