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

Which EIGRP table stores information about all learned routes and potential paths to destinations?<\/b><\/p>\n

    \n
  1. Neighbor table<\/span><\/li>\n
  2. Routing table<\/span><\/li>\n
  3. Topology table<\/span><\/li>\n
  4. ARP table<\/span><\/li>\n<\/ol>\n

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

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

    The EIGRP topology table stores information about routes learned from EIGRP neighbors and the available paths toward destinations. It contains information such as the feasible distance, reported distance, successor, and qualifying feasible successors. The routing table contains only the paths selected for forwarding traffic, while the topology table can retain additional alternatives. The neighbor table is used to track EIGRP peers and their adjacency information. Administrators commonly examine the topology table when troubleshooting route selection, convergence, and feasible successors. Because EIGRP maintains this additional path information, it can often converge quickly after a successor becomes unavailable when a valid feasible successor already exists.<\/span><\/p>\n

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

    Which BGP attribute is Cisco-specific and is considered before Local Preference during the BGP best-path selection process?<\/b><\/p>\n

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

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

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

      Weight is a Cisco-specific BGP attribute used to influence path selection locally on a router. A higher Weight value is preferred. It is evaluated before Local Preference in the Cisco BGP best-path process, making it a powerful local policy tool. Unlike Local Preference, Weight is not advertised to BGP peers and therefore affects only the router where it is configured. Administrators may assign a higher Weight to routes learned from a preferred neighbor to force that router to select a particular path. Because Weight is local to the router, it does not provide an autonomous-system-wide policy in the same way Local Preference does.<\/span><\/p>\n

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

      Which OSPF LSA type describes a multiaccess network and is generated by the DR?<\/b><\/p>\n

        \n
      1. Type 3<\/span><\/li>\n
      2. Type 5<\/span><\/li>\n
      3. Type 2<\/span><\/li>\n
      4. Type 4<\/span><\/li>\n<\/ol>\n

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

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

        A Type 2 Network LSA is generated by the Designated Router on multiaccess OSPF networks such as Ethernet segments. It describes the routers attached to that shared network and represents the multiaccess segment within the OSPF link-state database. The use of a DR and BDR reduces the number of full adjacencies required between routers on the same segment. Type 1 LSAs describe individual routers, Type 3 LSAs advertise networks between areas, and Type 5 LSAs describe external routes. When troubleshooting OSPF on broadcast networks, checking the DR and the presence of the expected Type 2 LSA can help verify proper network representation.<\/span><\/p>\n

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

        Which EIGRP packet is sent when a router needs additional information about an unavailable route?<\/b><\/p>\n

          \n
        1. Reply<\/span><\/li>\n
        2. Query<\/span><\/li>\n
        3. Update<\/span><\/li>\n
        4. Hello<\/span><\/li>\n<\/ol>\n

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

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

          EIGRP sends a Query packet when a router loses its successor and does not have a feasible successor available for the destination. The router asks neighboring EIGRP routers whether they have an alternate route to that destination. Neighboring routers process the Query and respond with Reply packets. This process is part of EIGRP’s DUAL convergence mechanism. Excessive Query propagation can create scalability and convergence problems, especially in large networks. Features such as EIGRP stub routing and route summarization can help limit the scope of Queries. Monitoring EIGRP Query and Reply behavior is therefore useful when investigating slow convergence or stuck-in-active conditions.<\/span><\/p>\n

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

          Which BGP attribute generally prefers a route with a lower numerical value?<\/b><\/p>\n

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

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

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

            MED, or Multi-Exit Discriminator, is generally preferred when it has a lower numerical value. It can be used to influence which entry point an external autonomous system should use when multiple links exist between the same autonomous systems. Unlike Local Preference, which is normally higher-is-better, MED follows a lower-is-better comparison. MED is considered relatively late in the BGP best-path process, after attributes such as Weight, Local Preference, and AS Path. Its actual comparison behavior can also depend on BGP configuration and policy. Therefore, MED should be considered a traffic-engineering attribute rather than a universal guarantee of inbound path selection.<\/span><\/p>\n

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

            Which OSPF command displays detailed information about the OSPF process, including the router ID and areas?<\/b><\/p>\n

              \n
            1. show ip ospf<\/span><\/li>\n
            2. show ip ospf neighbor<\/span><\/li>\n
            3. show ip ospf database<\/span><\/li>\n
            4. show ip route ospf<\/span><\/li>\n<\/ol>\n

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

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

              The show ip ospf command displays information about the OSPF routing process running on a Cisco router. Depending on the configuration, the output includes the process ID, router ID, areas, SPF statistics, timers, and other process-level information. It is useful when verifying how OSPF is configured and understanding the relationship between the router and its participating areas. The show ip ospf neighbor command focuses specifically on neighbor adjacencies, while show ip ospf database displays LSDB information. The show ip route ospf command instead displays OSPF-learned routes in the routing table. These commands complement each other during OSPF troubleshooting.<\/span><\/p>\n

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

              Which EIGRP administrative distance is assigned by default to internal EIGRP routes?<\/b><\/p>\n

                \n
              1. 170<\/span><\/li>\n
              2. 110<\/span><\/li>\n
              3. 90<\/span><\/li>\n
              4. 120<\/span><\/li>\n<\/ol>\n

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

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

                Cisco routers assign an administrative distance of 90 to internal EIGRP routes by default. Administrative distance determines the trust level of a route source when multiple routing protocols provide information about the same destination. A lower administrative distance is preferred. External EIGRP routes have a default administrative distance of 170 because they originated from another routing source and were redistributed into EIGRP. OSPF has a default administrative distance of 110, while RIP commonly uses 120. Knowing EIGRP’s administrative distance is important when multiple routing protocols operate together and a router must determine which routing source should be installed in the routing table.<\/span><\/p>\n

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

                Which BGP state indicates that the TCP connection has been successfully established and BGP peers can exchange routing information?<\/b><\/p>\n

                  \n
                1. Active<\/span><\/li>\n
                2. OpenSent<\/span><\/li>\n
                3. Established<\/span><\/li>\n
                4. Idle<\/span><\/li>\n<\/ol>\n

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

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

                  The Established BGP state indicates that the BGP session has successfully completed the necessary negotiation and is ready to exchange routing information. In this state, BGP Update messages can advertise routes and withdraw routes. Earlier states include Idle, Connect, Active, OpenSent, and OpenConfirm. Problems that prevent a session from reaching Established can include TCP connectivity failures, incorrect neighbor configuration, authentication mismatches, incompatible AS numbers, or routing problems affecting the peer address. The show ip bgp summary command is commonly used to determine the current BGP neighbor state and whether prefixes are being received. Established therefore represents a functioning BGP peering relationship.<\/span><\/p>\n

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

                  Which OSPF LSA type carries external routes redistributed into an OSPF autonomous system?<\/b><\/p>\n

                    \n
                  1. Type 1<\/span><\/li>\n
                  2. Type 3<\/span><\/li>\n
                  3. Type 5<\/span><\/li>\n
                  4. Type 2<\/span><\/li>\n<\/ol>\n

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

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

                    Type 5 LSAs, called AS External LSAs, are used to advertise routes redistributed into OSPF from another routing source. An ASBR generates these LSAs when it introduces external routing information into the OSPF domain. Type 5 LSAs are normally flooded throughout the OSPF autonomous system, except into areas where external LSAs are specifically restricted, such as standard stub areas. In an NSSA, external routes are initially represented using Type 7 LSAs and can later be translated to Type 5 by an appropriate ABR. Understanding these LSA types is essential when troubleshooting route redistribution and external reachability in OSPF.<\/span><\/p>\n

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

                    Which EIGRP feature allows unequal-cost paths to participate in load balancing?<\/b><\/p>\n

                      \n
                    1. Stub routing<\/span><\/li>\n
                    2. Variance<\/span><\/li>\n
                    3. Split horizon<\/span><\/li>\n
                    4. Summarization<\/span><\/li>\n<\/ol>\n

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

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

                      EIGRP variance enables unequal-cost load balancing when multiple paths meet the necessary EIGRP requirements. The variance value acts as a multiplier applied to the feasible distance of the best path. An alternate route must satisfy the feasibility condition before it can be considered for unequal-cost load balancing. Simply increasing the variance does not automatically make every available route usable. This mechanism allows EIGRP to use paths with different metrics, which can improve utilization of available network links. Administrators should carefully evaluate bandwidth, delay, and traffic behavior before implementing unequal-cost load balancing because multiple paths may carry traffic according to the routing platform’s load-sharing behavior.<\/span><\/p>\n

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

                      Which BGP attribute is normally advertised to internal BGP peers and helps control outbound traffic from an autonomous system?<\/b><\/p>\n

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

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

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

                        Local Preference is a BGP attribute used within an autonomous system to influence outbound traffic. A higher Local Preference is normally preferred when BGP compares candidate paths. Unlike Weight, which is local to a single Cisco router, Local Preference can be propagated through iBGP and therefore supports consistent policy across multiple routers in the same autonomous system. Administrators can use it to designate primary and backup external connections. For example, routes learned through one provider can receive a higher Local Preference than equivalent routes learned through another provider. This causes internal BGP routers to prefer the path associated with the higher value when other relevant factors do not override the decision.<\/span><\/p>\n

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

                        Which OSPF neighbor state occurs when a router has received a Hello packet from a neighbor but its own Router ID is not yet listed in the neighbor’s Hello packet?<\/b><\/p>\n

                          \n
                        1. Full<\/span><\/li>\n
                        2. Exchange<\/span><\/li>\n
                        3. Init<\/span><\/li>\n
                        4. Loading<\/span><\/li>\n<\/ol>\n

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

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

                          The Init state occurs when an OSPF router receives a Hello packet from a neighbor but does not yet see its own Router ID listed in the neighbor’s Hello message. This indicates that communication has begun, but bidirectional communication has not yet been confirmed. Once a router sees its own Router ID in the neighbor’s Hello packet, the relationship can progress to the 2-Way state. On broadcast networks, routers may remain in 2-Way with non-DR and non-BDR neighbors. Persistent Init states can indicate problems such as unidirectional communication, filtering, incorrect network configuration, or packet delivery issues.<\/span><\/p>\n

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

                          Which EIGRP command displays information about interfaces participating in EIGRP?<\/b><\/p>\n

                            \n
                          1. show ip eigrp topology<\/span><\/li>\n
                          2. show ip eigrp interfaces<\/span><\/li>\n
                          3. show ip eigrp neighbors<\/span><\/li>\n
                          4. show ip route eigrp<\/span><\/li>\n<\/ol>\n

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

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

                            The show ip eigrp interfaces command provides information about interfaces participating in EIGRP. It can display details such as the EIGRP process, interface status, peer counts, packet statistics, and other interface-related information depending on the command options and platform. This makes it useful for troubleshooting whether EIGRP is correctly enabled on an interface and whether the interface is exchanging EIGRP traffic. The neighbor command focuses on peer relationships, while the topology command displays routing information and path details. The route command displays EIGRP routes installed in the routing table. Together, these commands provide different perspectives during EIGRP troubleshooting.<\/span><\/p>\n

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

                            Which BGP message is used to maintain an established BGP session when no Update messages are being exchanged?<\/b><\/p>\n

                              \n
                            1. Notification<\/span><\/li>\n
                            2. Open<\/span><\/li>\n
                            3. Keepalive<\/span><\/li>\n
                            4. Update<\/span><\/li>\n<\/ol>\n

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

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

                              BGP Keepalive messages are exchanged periodically to maintain an established BGP session when routing updates are not otherwise being sent. They allow each BGP peer to verify that the other peer remains reachable and responsive. If the Hold Timer expires without receiving an acceptable BGP message, the session can be considered failed and terminated. Open messages establish the session parameters, Update messages advertise or withdraw routing information, and Notification messages report errors and terminate the session. Keepalive behavior is therefore important for maintaining stable BGP peering relationships and detecting failures when no regular routing changes are occurring.<\/span><\/p>\n

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

                              Which OSPF area is considered the backbone area and connects other OSPF areas?<\/b><\/p>\n

                                \n
                              1. Area 1<\/span><\/li>\n

                              4. Area 255<\/span><\/li>\n<\/ol>\n

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

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

                                Area 0 is the OSPF backbone area. In a multi-area OSPF design, other areas are normally connected to the backbone through Area Border Routers. The backbone provides the logical structure through which inter-area routing information is exchanged. OSPF Type 3 Summary LSAs are used by ABRs to advertise networks between areas. A design in which an area is not directly connected to Area 0 may require special mechanisms such as an OSPF virtual link, although proper network design generally keeps the backbone continuous. Understanding the role of Area 0 is fundamental to designing and troubleshooting multi-area OSPF topologies.<\/span><\/p>\n

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

                                Which EIGRP component represents the metric reported by a neighboring router for reaching a destination?<\/b><\/p>\n

                                  \n

                                4. Variance<\/span><\/li>\n<\/ol>\n

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

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

                                  Reported Distance, also called Advertised Distance in some Cisco documentation, represents the metric that an EIGRP neighbor reports for reaching a destination. The local router uses this value when evaluating the feasibility condition. The local Feasible Distance represents the best known metric from the local router to the destination, while the Reported Distance represents the neighbor’s metric to that destination. For a route to qualify as a feasible successor, the neighbor’s Reported Distance must be less than the local Feasible Distance. Understanding these two values is essential when analyzing EIGRP topology output and determining whether an alternate path can be used without risking a routing loop.<\/span><\/p>\n

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

                                  Which BGP attribute represents the sequence of autonomous systems through which a route has passed?<\/b><\/p>\n

                                    \n

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

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

                                    The AS Path attribute records the sequence of autonomous systems that a BGP route has traversed. When an eBGP router advertises a route to another autonomous system, its own AS number is added to the AS Path. This attribute serves two important purposes: it provides information about the path and helps prevent routing loops. If a BGP router receives a route containing its own autonomous system number in the AS Path, it normally rejects that route as a loop-prevention measure. AS Path length can also influence best-path selection, although attributes such as Weight and Local Preference are evaluated earlier in Cisco’s BGP decision process.<\/span><\/p>\n

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

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

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

                                      The show ip ospf database command displays information contained in the OSPF link-state database. The output can include different LSA types, such as Router LSAs, Network LSAs, Summary LSAs, ASBR Summary LSAs, and AS External LSAs. This command is particularly useful when troubleshooting missing routes, unexpected topology information, or LSA flooding problems. The OSPF database should generally contain synchronized information among routers within the same area. The show ip ospf neighbor command instead focuses on adjacency states, while show ip route ospf displays routes selected by the routing process. Examining the LSDB can reveal whether the expected topology information is actually present.<\/span><\/p>\n

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

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

                                        EIGRP split horizon prevents a router from advertising a route out of the same interface through which that route was learned. This behavior helps reduce the possibility of routing loops and unnecessary routing updates. It is particularly relevant in networks where multiple routers share an interface or where hub-and-spoke designs use a common network segment. Split horizon is a loop-prevention mechanism, while variance is related to unequal-cost load balancing. A feasible successor is an alternate loop-free EIGRP path identified through the feasibility condition. Administrators should understand split-horizon behavior when troubleshooting situations where a route is unexpectedly not being advertised to a particular neighbor.<\/span><\/p>\n

                                        Which BGP attribute is generally preferred when its value indicates an IGP-originated route rather than an incomplete-origin route?<\/b><\/p>\n

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

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

                                          The BGP Origin attribute identifies how a route was introduced into BGP. The three common Origin values are IGP, EGP, and Incomplete. When BGP compares routes at the Origin stage, IGP is generally preferred over EGP, and EGP is preferred over Incomplete. Routes introduced using a BGP network statement commonly have an IGP Origin, while routes redistributed into BGP commonly receive an Incomplete Origin. Origin is evaluated only after several other BGP path-selection criteria, including Weight, Local Preference, and AS Path. Therefore, a route with an IGP Origin does not automatically win if another route has a more preferred attribute earlier in the decision process.<\/span><\/p>\n
