Question 101<\/b><\/h3>\n

A large enterprise is designing a data center interconnection architecture. The design must support Layer 2 and Layer 3 connectivity, provide multipathing, and allow scalable segmentation across data centers. Which technology is most suitable?<\/b><\/p>\n

    \n
  1. STP<\/span><\/li>\n
  2. VXLAN EVPN<\/span><\/li>\n
  3. HSRP<\/span><\/li>\n
  4. GRE<\/span><\/li>\n<\/ol>\n

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

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

    VXLAN EVPN provides a scalable architecture for modern data center environments by combining VXLAN encapsulation with BGP EVPN control-plane signaling. VXLAN enables Layer 2 segments to operate across a Layer 3 underlay, while EVPN distributes MAC and IP reachability information through BGP. The architecture supports multipathing through ECMP and provides segmentation using VXLAN Network Identifiers. STP is not normally used as the primary control mechanism across a VXLAN fabric. HSRP provides first-hop gateway redundancy, while GRE provides generic tunneling without the integrated control-plane and data-center scalability features of VXLAN EVPN.<\/span><\/p>\n

    Question 102<\/b><\/h3>\n

    A network architect needs to influence which exit point internal routers use when sending traffic toward external destinations through multiple BGP connections. Which BGP attribute should primarily be used?<\/b><\/p>\n

      \n
    1. MED<\/span><\/li>\n
    2. Origin<\/span><\/li>\n
    3. AS Path<\/span><\/li>\n
    4. Local Preference<\/span><\/li>\n<\/ol>\n

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

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

      Local Preference is used within an autonomous system to influence outbound traffic selection. A higher Local Preference value is preferred and can cause routers throughout the autonomous system to select a particular exit point. Because the attribute is propagated through iBGP, it can be used to establish a consistent outbound traffic policy across multiple routers. MED can influence how a neighboring autonomous system selects an entry point, while AS Path length is another BGP path-selection factor. The Origin attribute has a lower priority in the selection process and is not normally the primary mechanism for controlling internal outbound traffic.<\/span><\/p>\n

      Question 103<\/b><\/h3>\n

      A service provider is connecting several customers over the same MPLS infrastructure. Each customer must have isolated routing information even when customers use overlapping IP address ranges. Which technology provides this capability?<\/b><\/p>\n

        \n
      1. VRF<\/span><\/li>\n
      2. STP<\/span><\/li>\n
      3. EtherChannel<\/span><\/li>\n
      4. HSRP<\/span><\/li>\n<\/ol>\n

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

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

        Virtual Routing and Forwarding (VRF) creates independent routing and forwarding tables on a router. In an MPLS Layer 3 VPN architecture, separate customer VRFs allow multiple customers to use the same physical provider infrastructure while keeping their routing information isolated. VRFs also allow customers to use overlapping IP address spaces because the routes exist in separate routing tables. Route distinguishers and route targets are commonly used with MPLS VPNs to maintain uniqueness and control route import and export. STP provides Layer 2 loop prevention, EtherChannel aggregates links, and HSRP provides gateway redundancy rather than customer route isolation.<\/span><\/p>\n

        Question 104<\/b><\/h3>\n

        An enterprise wants its network to remain operational if one core router fails. Which architectural principle should be incorporated into the design?<\/b><\/p>\n

          \n
        1. Route summarization<\/span><\/li>\n
        2. Traffic filtering<\/span><\/li>\n
        3. Device redundancy<\/span><\/li>\n
        4. Single-homing<\/span><\/li>\n<\/ol>\n

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

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

          Device redundancy is a fundamental network availability principle. By deploying redundant core routers, an enterprise can maintain connectivity when one router fails. Redundant devices can work with dynamic routing protocols, first-hop redundancy protocols, and multiple physical links to provide rapid failover. Route summarization helps reduce routing-table size but does not directly provide protection against hardware failure. Traffic filtering is primarily used for security and policy enforcement. Single-homing creates a dependency on one connection or device and therefore introduces a potential single point of failure. A resilient design should minimize such dependencies.<\/span><\/p>\n

          Question 105<\/b><\/h3>\n

          A company has a large OSPF deployment and wants to reduce the amount of routing information exchanged between areas. Which design technique should be considered?<\/b><\/p>\n

            \n
          1. Route redistribution<\/span><\/li>\n
          2. Route summarization<\/span><\/li>\n
          3. Policy-based routing<\/span><\/li>\n
          4. NAT<\/span><\/li>\n<\/ol>\n

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

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

            Route summarization allows multiple specific network prefixes to be represented by a single summarized prefix. In an OSPF design, summarization can be performed at appropriate area boundaries to reduce the amount of routing information propagated between areas. This can reduce routing-table size, decrease SPF processing requirements, and limit the impact of topology changes. Route redistribution is intended to exchange routes between different routing protocols or routing domains and may introduce additional complexity. Policy-based routing controls forwarding based on configured policies, while NAT translates addresses. Neither is primarily intended to reduce OSPF routing information.<\/span><\/p>\n

            Question 106<\/b><\/h3>\n

            An OSPF area should not receive external Type 5 LSAs from another part of the autonomous system. Which OSPF area type is designed for this purpose?<\/b><\/p>\n

              \n
            1. Backbone area<\/span><\/li>\n
            2. Transit area<\/span><\/li>\n
            3. Point-to-point area<\/span><\/li>\n
            4. Stub area<\/span><\/li>\n<\/ol>\n

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

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

              An OSPF stub area is designed to reduce the amount of external routing information that must be maintained inside the area. Type 5 LSAs, which represent external routes, are not propagated into a standard stub area. Instead, a default route can be used to provide reachability toward destinations outside the area. This can reduce the size of the link-state database and routing table and simplify the design of smaller OSPF areas. Backbone and transit areas have different roles in OSPF, while a point-to-point network type describes the relationship between two OSPF neighbors rather than defining an OSPF area type.<\/span><\/p>\n

              Question 107<\/b><\/h3>\n

              A network requires multiple equal-cost paths to be used simultaneously for traffic forwarding. Which capability should be implemented?<\/b><\/p>\n

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

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

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

                Equal-Cost Multipath (ECMP) allows a router to install and use multiple routes toward the same destination when those routes have equal routing costs. Traffic can then be distributed across the available paths according to the platform’s load-balancing mechanism. ECMP improves bandwidth utilization and provides path redundancy because traffic can continue using remaining paths if one path becomes unavailable. NAT is used for address translation, policy-based routing selects paths according to configured policies, and route filtering controls which routes are accepted or advertised. These functions do not directly provide equal-cost multipath forwarding.<\/span><\/p>\n

                Question 108<\/b><\/h3>\n

                A company operates multiple BGP connections to different providers and wants to influence outbound traffic so that internal routers prefer one provider’s connection. Which attribute is most appropriate?<\/b><\/p>\n

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

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

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

                  Local Preference is commonly used to control outbound traffic within an autonomous system. A higher Local Preference is preferred by BGP, allowing network architects to designate a preferred external exit point. The attribute is distributed through iBGP, so multiple internal routers can make consistent path-selection decisions. MED is generally used to provide information to a neighboring autonomous system about preferred inbound entry points. BGP communities are tags that can be used to apply policies, but their actual behavior depends on configured policy. Router ID identifies the BGP speaker and does not directly determine the preferred outbound provider.<\/span><\/p>\n

                  Question 109<\/b><\/h3>\n

                  A service provider needs to transport Layer 2 Ethernet traffic across a Layer 3 IP infrastructure while maintaining scalable tunnel endpoints. Which technology is appropriate?<\/b><\/p>\n

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

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

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

                    VXLAN is designed to provide Layer 2 network virtualization over a Layer 3 IP underlay. Ethernet frames are encapsulated inside VXLAN and transported between VXLAN Tunnel Endpoints. This allows Layer 2 segments to span a routed infrastructure without requiring the underlying network to operate as one large Layer 2 domain. VXLAN also provides a much larger segmentation space than traditional VLANs through its 24-bit VNI field. DHCP provides address assignment, HSRP provides first-hop redundancy, and OSPF is a routing protocol. These technologies do not provide the same Layer 2-over-Layer 3 virtualization function.<\/span><\/p>\n

                    Question 110<\/b><\/h3>\n

                    A network architect is designing connectivity between two data centers and wants to avoid creating a single point of failure at the WAN edge. Which approach provides the most direct redundancy?<\/b><\/p>\n

                      \n
                    1. Use a single WAN router with multiple VLANs<\/span><\/li>\n
                    2. Deploy redundant WAN edge devices and diverse links<\/span><\/li>\n
                    3. Increase the MTU on the existing WAN connection<\/span><\/li>\n
                    4. Disable dynamic routing between the data centers<\/span><\/li>\n<\/ol>\n

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

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

                      Deploying redundant WAN edge devices together with diverse physical or logical links removes single points of failure from the WAN edge. Dynamic routing can detect failures and select alternate paths, allowing traffic to continue flowing when a device or connection becomes unavailable. Diverse links are particularly useful when they follow different physical paths or provider infrastructures, reducing the risk of a common failure affecting both connections. Increasing MTU does not provide redundancy, while using a single router still leaves a device-level failure domain. Disabling dynamic routing can also make failure recovery more difficult.<\/span><\/p>\n

                      Question 111<\/b><\/h3>\n

                      An enterprise wants to separate voice, video, and business-critical application traffic and ensure that delay-sensitive traffic receives appropriate treatment during congestion. Which design capability should be implemented?<\/b><\/p>\n

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

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

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

                        Quality of Service (QoS) provides mechanisms for classifying, marking, queuing, policing, and scheduling traffic according to business and application requirements. Voice and interactive video are generally sensitive to latency, jitter, and packet loss, so appropriate QoS policies can give these traffic classes preferential treatment during periods of congestion. QoS does not create additional bandwidth, but it determines how available bandwidth is managed. NAT performs address translation, DNS resolves names to addresses, and DHCP provides network configuration parameters. Therefore, QoS is the appropriate design capability when traffic needs differentiated treatment based on application requirements.<\/span><\/p>\n

                        Question 112<\/b><\/h3>\n

                        A network uses BGP between two autonomous systems. The architect wants to reduce the number of prefixes advertised to the external peer without losing reachability to the summarized networks. Which technique should be used?<\/b><\/p>\n

                          \n
                        1. Route reflection<\/span><\/li>\n
                        2. Anycast<\/span><\/li>\n
                        3. Route summarization<\/span><\/li>\n
                        4. Split horizon<\/span><\/li>\n<\/ol>\n

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

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

                          Route summarization combines multiple more-specific prefixes into a larger aggregate prefix. Advertising the aggregate to an external BGP peer can significantly reduce the number of routes carried between autonomous systems. This can lower routing-table size and reduce the amount of routing information that must be processed. The architect must ensure that the summary accurately represents reachable networks and understand the behavior when individual component routes become unavailable. Route reflection is primarily an iBGP scaling mechanism, anycast provides a common address from multiple locations, and split horizon is associated with loop prevention mechanisms. Route summarization directly addresses prefix reduction.<\/span><\/p>\n

                          Question 113<\/b><\/h3>\n

                          A company wants to use two data center sites as active forwarding locations and distribute traffic across both sites while maintaining consistent application reachability. Which design concept is most relevant?<\/b><\/p>\n

                            \n
                          1. Active-active architecture<\/span><\/li>\n
                          2. Cold standby<\/span><\/li>\n
                          3. Single-homed architecture<\/span><\/li>\n
                          4. Manual failover only<\/span><\/li>\n<\/ol>\n

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

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

                            An active-active architecture allows both data center sites to participate in normal traffic forwarding rather than keeping one site idle as a standby. This can improve resource utilization and provide additional capacity while also providing redundancy. Traffic distribution can be implemented using routing, load balancing, DNS-based mechanisms, or other application-aware technologies depending on the requirements. A cold standby design keeps resources inactive until a failure occurs, while single-homing creates a dependency on one connection or location. Manual failover can be slower and may require operator intervention. The exact active-active design should account for state synchronization, latency, failure domains, and application behavior.<\/span><\/p>\n

                            Question 114<\/b><\/h3>\n

                            A network architect needs to prevent a route learned from one routing domain from being redistributed back into that same domain through another protocol. Which design mechanism can help prevent routing loops?<\/b><\/p>\n

                              \n
                            1. Increasing interface bandwidth<\/span><\/li>\n
                            2. Route tagging<\/span><\/li>\n
                            3. Changing the MTU<\/span><\/li>\n
                            4. Disabling ICMP<\/span><\/li>\n<\/ol>\n

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

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

                              Route tagging provides a mechanism for identifying routes according to their source or redistribution history. During redistribution between routing protocols, tags can be applied to routes entering a routing domain and then matched in route policies to prevent those same routes from being redistributed back into their original domain. This helps reduce the risk of routing loops and provides greater control over redistribution behavior. Increasing bandwidth and changing MTU affect packet transport characteristics rather than route-policy logic. Disabling ICMP also does not prevent routing loops. Proper route filtering and tagging are important when multiple routing protocols interact.<\/span><\/p>\n

                              Question 115<\/b><\/h3>\n

                              An enterprise has several remote locations connected through an IP WAN and requires encrypted site-to-site communication over an untrusted network. Which technology is most appropriate?<\/b><\/p>\n

                                \n
                              1. VXLAN<\/span><\/li>\n
                              2. IPsec<\/span><\/li>\n
                              3. STP<\/span><\/li>\n
                              4. VRRP<\/span><\/li>\n<\/ol>\n

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

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

                                IPsec provides encryption, authentication, integrity, and secure communication across untrusted IP networks. It is commonly used to establish site-to-site VPN tunnels between enterprise locations over the Internet or another untrusted transport. Depending on the architecture, IPsec can operate with routing protocols and different tunnel designs to support scalable connectivity. VXLAN provides network virtualization rather than encryption, STP prevents Layer 2 loops, and VRRP provides first-hop gateway redundancy. IPsec should therefore be considered when the primary requirement is protecting traffic between remote sites across an untrusted network.<\/span><\/p>\n

                                Question 116<\/b><\/h3>\n

                                A network architect wants to provide gateway redundancy for hosts in a VLAN so that the default gateway remains available if one router fails. Which technology should be considered?<\/b><\/p>\n

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

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

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

                                  Hot Standby Router Protocol (HSRP) provides first-hop gateway redundancy for hosts on a LAN or VLAN. Multiple routers can participate in an HSRP group, with one router serving as the active gateway and another available as a standby. If the active router becomes unavailable, the standby can assume the active role and continue providing gateway services. BGP and OSPF are routing protocols and do not directly provide the same host default-gateway redundancy function. VXLAN is a network virtualization technology. HSRP can therefore be useful when the design requires resilient default-gateway services without changing the host configuration.<\/span><\/p>\n

                                  Question 117<\/b><\/h3>\n

                                  A company wants to ensure that internal BGP routes can be distributed among multiple route reflectors to improve scalability and provide redundancy. Which design consideration is important?<\/b><\/p>\n

                                    \n

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

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

                                    Route reflectors are used to reduce the requirement for a full-mesh iBGP topology. In a scalable design, multiple route reflectors can be deployed to provide redundancy and reduce dependence on a single control-plane device. Client relationships and route-reflector topology should be designed carefully to ensure that routes are propagated as expected and that failure of one reflector does not isolate clients. Using only static routes does not provide the scalability and dynamic control expected from BGP. Disabling iBGP sessions would undermine the purpose of route reflection, while removing communities eliminates useful policy information that may be required for routing decisions.<\/span><\/p>\n

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

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

                                      Failure-domain isolation limits the scope of failures and prevents a problem in one region or segment from unnecessarily affecting the rest of the network. Appropriate routing boundaries, summarization, redundancy, and controlled topology design can help contain failures. Smaller and well-defined failure domains make troubleshooting and recovery more manageable. Large broadcast domains can increase the scope of Layer 2 problems, while single-path forwarding removes redundancy. Removing route summarization can increase the amount of routing information exchanged and may allow more detailed changes to propagate widely. Therefore, isolating failure domains is an important principle for resilient multi-region network design.<\/span><\/p>\n

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

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

                                        Dynamic routing protocols can detect topology changes and calculate alternate paths automatically. When combined with redundant paths and appropriately tuned detection and convergence mechanisms, they can provide relatively fast recovery after a link failure. Technologies such as BFD can also improve failure detection time where supported and appropriate. Static routes without tracking may not react automatically to failures, while disabling routing protocols removes dynamic path recalculation. Increasing broadcast traffic does not improve routing convergence and can create unnecessary overhead. The exact convergence strategy should consider network scale, stability, hardware capabilities, and application requirements.<\/span><\/p>\n

                                        A company wants to enforce different forwarding behavior for selected applications based on source, destination, or other packet characteristics rather than relying only on the destination routing table.

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

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

                                          Policy-Based Routing (PBR) allows forwarding decisions to be based on configured policies rather than solely on the destination address and normal routing-table lookup. Policies can match characteristics such as source address, destination address, protocol, or other supported criteria and then specify an alternate next hop or forwarding behavior. This can be useful when particular applications or traffic classes need to follow a path different from the normal routing decision. ECMP distributes traffic across equal-cost routes, route summarization reduces routing information, and STP prevents Layer 2 loops. PBR is therefore the technology designed for policy-driven forwarding decisions.<\/span><\/p>\n
