Question 181<\/b><\/h3>\n

A large enterprise is designing an IPv4 network and wants to reduce the size of routing tables by representing several contiguous networks with a single prefix. Which technique should be used?<\/b><\/p>\n

    \n
  1. Route redistribution<\/span><\/li>\n
  2. Route summarization<\/span><\/li>\n
  3. Policy-Based Routing<\/span><\/li>\n
  4. Route reflection<\/span><\/li>\n<\/ol>\n

    Correct Answer: 2<\/b><\/p>\n

    Explanation<\/b><\/h3>\n

    Route summarization combines multiple specific network prefixes into a single larger aggregate prefix. This reduces the number of routes that routers need to maintain and advertise. Summarization can also reduce routing-protocol processing and limit the propagation of some topology changes. Route redistribution moves routes between routing protocols, Policy-Based Routing changes forwarding behavior according to policies, and route reflection is primarily used to improve iBGP scalability. Route summarization is therefore the appropriate technique when the objective is to reduce routing-table size.<\/span><\/p>\n

    Question 182<\/b><\/h3>\n

    A network architect needs to provide rapid detection of forwarding-path failures between two routers so that the routing protocol can converge quickly. Which technology is most appropriate?<\/b><\/p>\n

      \n
    1. DHCP<\/span><\/li>\n
    2. NAT<\/span><\/li>\n
    3. BFD<\/span><\/li>\n
    4. DNS<\/span><\/li>\n<\/ol>\n

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

      Explanation<\/b><\/h3>\n

      Bidirectional Forwarding Detection (BFD) is designed to detect forwarding-path failures rapidly between neighboring network devices. It can operate independently of normal routing-protocol timers and notify supported routing protocols when a failure occurs. This allows protocols such as BGP, OSPF, or IS-IS to react more quickly to a failed path. DHCP provides host configuration, NAT performs address translation, and DNS provides name resolution. BFD is therefore particularly useful in networks where fast failure detection and convergence are important design requirements.<\/span><\/p>\n

      Question 183<\/b><\/h3>\n

      An enterprise uses multiple BGP providers and wants to influence inbound traffic by communicating a preferred entry point to a neighboring autonomous system. Which BGP attribute can be used for this purpose?<\/b><\/p>\n

        \n
      1. Local Preference<\/span><\/li>\n
      2. MED<\/span><\/li>\n
      3. Weight<\/span><\/li>\n
      4. Router ID<\/span><\/li>\n<\/ol>\n

        Correct Answer: 2<\/b><\/p>\n

        Explanation<\/b><\/h3>\n

        Multi-Exit Discriminator (MED) can be used to communicate a preferred entry point into an autonomous system to a neighboring autonomous system. A lower MED is generally preferred when comparing paths from the same neighboring AS. This makes MED useful for influencing inbound traffic engineering in appropriate BGP designs. Local Preference is normally used within an autonomous system to influence outbound traffic. Weight is a local Cisco-specific attribute and is not advertised to BGP peers, while Router ID identifies the BGP speaker. MED is therefore relevant when communicating an inbound path preference.<\/span><\/p>\n

        Question 184<\/b><\/h3>\n

        A company needs separate routing domains for different departments while allowing them to share the same physical router. Which technology provides this capability?<\/b><\/p>\n

          \n
        1. VRF<\/span><\/li>\n
        2. ECMP<\/span><\/li>\n
        3. BFD<\/span><\/li>\n
        4. LACP<\/span><\/li>\n<\/ol>\n

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

          Explanation<\/b><\/h3>\n

          Virtual Routing and Forwarding creates independent routing and forwarding tables on a single physical router. Each department or tenant can therefore operate within its own logical routing domain while sharing the same hardware. VRFs are useful for segmentation, security, multi-tenancy, and overlapping IP address requirements. ECMP provides equal-cost multipath forwarding, BFD provides rapid failure detection, and LACP aggregates physical links. VRF is directly designed to provide independent routing domains on shared infrastructure.<\/span><\/p>\n

          Question 185<\/b><\/h3>\n

          A data center architect wants to provide multiple equal-cost paths between leaf switches and spine switches. Which technology is commonly used to distribute traffic across those paths?<\/b><\/p>\n

            \n
          1. NAT<\/span><\/li>\n
          2. ECMP<\/span><\/li>\n
          3. HSRP<\/span><\/li>\n
          4. Route filtering<\/span><\/li>\n<\/ol>\n

            Correct Answer: 2<\/b><\/p>\n

            Explanation<\/b><\/h3>\n

            ECMP allows network devices to use multiple routes with equal routing costs toward the same destination. In a leaf-and-spine data center architecture, multiple spine switches can provide equal-cost paths between leaf switches. Traffic can then be distributed across these paths according to the device’s load-balancing algorithm. This improves bandwidth utilization and provides redundancy. NAT performs address translation, HSRP provides gateway redundancy, and route filtering controls route acceptance or advertisement. ECMP is therefore a fundamental capability for multipath data center designs.<\/span><\/p>\n

            Question 186<\/b><\/h3>\n

            A network architect wants to prevent a single physical connection from becoming a point of failure between two switches. Which solution provides link redundancy while treating multiple links as one logical interface?<\/b><\/p>\n

              \n
            1. LACP EtherChannel<\/span><\/li>\n
            2. OSPF area<\/span><\/li>\n
            3. BGP community<\/span><\/li>\n
            4. VRF<\/span><\/li>\n<\/ol>\n

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

              Explanation<\/b><\/h3>\n

              LACP EtherChannel combines multiple physical Ethernet interfaces into one logical port-channel. The design provides redundancy because traffic can continue using the remaining member links if one physical connection fails. It can also provide additional aggregate bandwidth depending on the number and capacity of member links. OSPF areas organize IP routing domains, BGP communities carry routing-policy information, and VRF provides separate routing tables. LACP EtherChannel directly addresses the requirement for redundant physical connectivity between switches.<\/span><\/p>\n

              Question 187<\/b><\/h3>\n

              An organization wants to prioritize latency-sensitive voice and video traffic when a WAN link becomes congested. Which networking capability should be implemented?<\/b><\/p>\n

                \n
              1. NAT<\/span><\/li>\n
              2. QoS<\/span><\/li>\n
              3. ARP<\/span><\/li>\n
              4. DNS<\/span><\/li>\n<\/ol>\n

                Correct Answer: 2<\/b><\/p>\n

                Explanation<\/b><\/h3>\n

                Quality of Service provides mechanisms for classifying, marking, queuing, policing, and scheduling traffic according to application requirements. Voice and interactive video are sensitive to delay, jitter, and packet loss, so QoS policies can provide them with appropriate treatment during periods of congestion. QoS does not increase the physical bandwidth of a link; instead, it controls how available bandwidth is allocated among traffic classes. NAT performs address translation, ARP resolves IPv4 addresses to MAC addresses, and DNS performs name resolution. QoS is therefore the appropriate capability for prioritizing delay-sensitive traffic.<\/span><\/p>\n

                Question 188<\/b><\/h3>\n

                A service provider needs to transport customer VPN routes between multiple provider edge routers using a BGP-based control plane. Which technology should be used?<\/b><\/p>\n

                  \n
                1. STP<\/span><\/li>\n
                2. MP-BGP<\/span><\/li>\n
                3. HSRP<\/span><\/li>\n
                4. DHCP<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 2<\/b><\/p>\n

                  Explanation<\/b><\/h3>\n

                  Multiprotocol BGP is commonly used to distribute VPNv4 and VPNv6 routes between provider edge routers in MPLS Layer 3 VPN architectures. MP-BGP can carry additional address-family information and VPN-specific attributes required for customer route distribution. VRFs maintain customer-specific routing tables, while route targets control route import and export. STP handles Layer 2 loop prevention, HSRP provides gateway redundancy, and DHCP provides host configuration. MP-BGP is therefore the appropriate control-plane technology for distributing VPN routes between provider edge routers.<\/span><\/p>\n

                  Question 189<\/b><\/h3>\n

                  An enterprise wants to direct traffic from a specific source subnet through a firewall before reaching its destination, even though the normal routing table would select another path. Which feature can accomplish this?<\/b><\/p>\n

                    \n
                  1. ECMP<\/span><\/li>\n
                  2. Policy-Based Routing<\/span><\/li>\n
                  3. Route summarization<\/span><\/li>\n
                  4. BFD<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 2<\/b><\/p>\n

                    Explanation<\/b><\/h3>\n

                    Policy-Based Routing allows forwarding decisions to be based on criteria such as source address rather than only the destination routing table. A policy can match traffic from a particular source subnet and specify a firewall or other next hop as the required forwarding destination. This makes PBR useful for security inspection, traffic engineering, and application-specific forwarding. ECMP distributes traffic among equal-cost paths, route summarization reduces routing information, and BFD detects forwarding failures. PBR is therefore appropriate when traffic must follow a specific policy-driven path.<\/span><\/p>\n

                    Question 190<\/b><\/h3>\n

                    A company wants to advertise a service from several network locations using the same IP address so that routing can select an available location. Which networking concept is being used?<\/b><\/p>\n

                      \n
                    1. Anycast<\/span><\/li>\n
                    2. NAT<\/span><\/li>\n
                    3. VLAN trunking<\/span><\/li>\n
                    4. Port security<\/span><\/li>\n<\/ol>\n

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

                      Explanation<\/b><\/h3>\n

                      Anycast allows multiple network locations to advertise the same IP address or prefix. Routing then determines which available location receives the traffic based on the routing topology and configured metrics. This design is frequently used for distributed services where multiple locations can provide the same application or service. NAT performs address translation, VLAN trunking transports multiple VLANs across a link, and port security restricts device access to switch ports. Anycast directly supports the requirement for a common service address across multiple locations.<\/span><\/p>\n

                      Question 191<\/b><\/h3>\n

                      A network architect is designing an MPLS Layer 3 VPN service and needs to distinguish identical customer prefixes belonging to different VPNs. Which component provides this uniqueness?<\/b><\/p>\n

                        \n
                      1. Route Target<\/span><\/li>\n
                      2. Route Distinguisher<\/span><\/li>\n
                      3. Local Preference<\/span><\/li>\n
                      4. BGP Weight<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 2<\/b><\/p>\n

                        Explanation<\/b><\/h3>\n

                        A Route Distinguisher (RD) is used to make otherwise identical customer prefixes unique within the VPNv4 or VPNv6 address space. For example, two different customers can both use the same IPv4 prefix, but the RD creates unique VPN routes for each customer. Route Targets serve a different purpose: they control which VPN routes are imported into or exported from VRFs. Local Preference influences BGP path selection within an autonomous system, while Weight is a local Cisco-specific attribute. The RD therefore provides the required route uniqueness.<\/span><\/p>\n

                        Question 192<\/b><\/h3>\n

                        A network uses multiple independent WAN paths and wants routing to automatically remove a failed path from forwarding decisions. Which design approach is most appropriate?<\/b><\/p>\n

                          \n
                        1. Static routing without tracking<\/span><\/li>\n
                        2. Dynamic routing with failure detection<\/span><\/li>\n
                        3. Single default route<\/span><\/li>\n
                        4. Disabling routing protocols<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 2<\/b><\/p>\n

                          Explanation<\/b><\/h3>\n

                          Dynamic routing combined with effective failure detection allows a network to detect unavailable paths and recalculate forwarding decisions. Technologies such as BFD can accelerate failure detection, while routing protocols can then remove the failed route and select an available alternative. Static routing without tracking may continue forwarding traffic toward an unavailable next hop. A single default route provides no path diversity, and disabling routing protocols prevents automatic route recalculation. Dynamic routing with failure detection is therefore appropriate for resilient multi-path WAN designs.<\/span><\/p>\n

                          Question 193<\/b><\/h3>\n

                          A large enterprise has hundreds of internal BGP routers and wants to avoid a full-mesh iBGP topology. Which technology can reduce the number of required BGP sessions?<\/b><\/p>\n

                            \n
                          1. Route reflector<\/span><\/li>\n
                          2. NAT<\/span><\/li>\n
                          3. HSRP<\/span><\/li>\n
                          4. VXLAN<\/span><\/li>\n<\/ol>\n

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

                            Explanation<\/b><\/h3>\n

                            BGP route reflectors reduce the need for every iBGP router to establish a session with every other iBGP router. Selected routers act as route reflectors and distribute routes to their clients according to configured BGP rules. This significantly improves scalability in large autonomous systems. Route reflectors should be deployed with appropriate redundancy and carefully planned client relationships. NAT performs address translation, HSRP provides gateway redundancy, and VXLAN provides network virtualization. Route reflection directly addresses iBGP scaling requirements.<\/span><\/p>\n

                            Question 194<\/b><\/h3>\n

                            A company needs to transport Layer 2 traffic between two data centers over a routed IP network. Which technology is designed to provide this Layer 2 overlay?<\/b><\/p>\n

                              \n
                            1. OSPF<\/span><\/li>\n
                            2. VXLAN<\/span><\/li>\n
                            3. BFD<\/span><\/li>\n
                            4. HSRP<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 2<\/b><\/p>\n

                              Explanation<\/b><\/h3>\n

                              VXLAN provides Layer 2 network virtualization over a Layer 3 IP underlay. Ethernet frames are encapsulated in VXLAN packets and transported between tunnel endpoints across the routed network. This allows Layer 2 segments to span routed infrastructure while maintaining scalable segmentation. In modern data center architectures, VXLAN is often paired with EVPN to distribute MAC and IP reachability information through a control plane. OSPF provides IP routing, BFD detects failures, and HSRP provides gateway redundancy. VXLAN is therefore the technology designed for this overlay requirement.<\/span><\/p>\n

                              Question 195<\/b><\/h3>\n

                              A network architect wants to control which prefixes are advertised to a specific external BGP neighbor. Which mechanism should be applied?<\/b><\/p>\n

                                \n
                              1. Outbound prefix filtering<\/span><\/li>\n
                              2. EtherChannel<\/span><\/li>\n
                              3. HSRP<\/span><\/li>\n
                              4. BFD<\/span><\/li>\n<\/ol>\n

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

                                Explanation<\/b><\/h3>\n

                                Outbound prefix filtering allows administrators to control which routes are advertised to a particular BGP neighbor. Prefix lists, route maps, and other routing policies can be used to permit only approved prefixes and prevent unwanted route advertisements. This is important for maintaining routing-policy control and preventing accidental route leaks. EtherChannel provides link aggregation, HSRP provides gateway redundancy, and BFD provides rapid failure detection. Outbound prefix filtering is therefore the appropriate mechanism for controlling BGP route advertisements to a specific peer.<\/span><\/p>\n

                                Question 196<\/b><\/h3>\n

                                A network design requires traffic from multiple applications to use different WAN paths based on latency, packet loss, and business requirements. Which architecture provides centralized policy-driven WAN path selection?<\/b><\/p>\n

                                  \n
                                1. SD-WAN<\/span><\/li>\n
                                2. STP<\/span><\/li>\n
                                3. Static VLAN routing<\/span><\/li>\n
                                4. Traditional hub-and-spoke bridging<\/span><\/li>\n<\/ol>\n

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

                                  Explanation<\/b><\/h3>\n

                                  SD-WAN provides centralized management and policy-based control over multiple WAN transports. It can evaluate network conditions such as latency, jitter, loss, and link availability and apply application-specific policies to select appropriate forwarding paths. This makes SD-WAN suitable for organizations that need dynamic traffic steering across different WAN connections. STP is intended for Layer 2 loop prevention, while static VLAN routing and traditional bridging do not provide the same centralized application-aware WAN path-selection capabilities. SD-WAN directly addresses the requirements of dynamic and policy-driven WAN traffic engineering.<\/span><\/p>\n

                                  Question 197<\/b><\/h3>\n

                                  A company has two customer networks using identical IPv4 address ranges and needs to maintain complete routing separation on a shared provider router. Which technology should be used?<\/b><\/p>\n

                                    \n
                                  1. ECMP<\/span><\/li>\n
                                  2. VRF<\/span><\/li>\n
                                  3. BFD<\/span><\/li>\n
                                  4. LACP<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 2<\/b><\/p>\n

                                    Explanation<\/b><\/h3>\n

                                    VRF provides independent routing and forwarding tables on a shared router. This allows different customers to use overlapping IPv4 address spaces while keeping their routing information logically separated. Each VRF can have its own interfaces, routes, and forwarding decisions. ECMP provides multipath forwarding, BFD provides rapid failure detection, and LACP aggregates physical links. VRF is therefore the appropriate technology for maintaining routing separation between customers with overlapping address spaces.<\/span><\/p>\n

                                    Question 198<\/b><\/h3>\n

                                    A network architect wants to improve convergence after a link failure without significantly lowering the normal routing protocol timers. Which mechanism can provide faster failure detection?<\/b><\/p>\n

                                      Explanation<\/b><\/h3>\n

                                      BFD provides rapid detection of forwarding-path failures and can work alongside routing protocols. Instead of relying solely on relatively conservative routing-protocol timers, BFD can detect a failure quickly and notify the associated routing protocol. This allows the routing process to begin convergence sooner while avoiding unnecessary aggressive changes to standard routing timers. NAT, DHCP, and DNS do not provide routing-failure detection. BFD is therefore useful when fast convergence is required while maintaining appropriate routing-protocol timer settings.<\/span><\/p>\n

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

                                        Explanation<\/b><\/h3>\n

                                        Route Targets determine which VPN routes are imported into or exported from a VRF. A provider can assign specific route-target values to customers and then configure VRFs to import only the required routes. This provides control over VPN route membership and allows different VPN topologies to be implemented. Route Distinguishers make VPN routes unique but do not determine route import and export policy. Router ID identifies a routing device, while MED can influence BGP path selection in certain external routing scenarios. Route Target is therefore the correct mechanism for controlling VPN route membership.<\/span><\/p>\n

                                          Correct Answer: 2<\/b><\/p>\n

                                          Explanation<\/b><\/h3>\n

                                          Device redundancy ensures that a network has an alternate device available when a primary device fails. In a highly available enterprise core, redundant routers or switches can operate with dynamic routing, first-hop redundancy, and multiple physical connections to maintain connectivity during failures. Single-homing creates a dependency on one connection, while larger broadcast domains can increase the scope of Layer 2 problems. Centralized single-path forwarding creates a potential single point of failure rather than eliminating one. Device redundancy is therefore a fundamental principle for designing a resilient network core.<\/span><\/p>\n
