Question 161. A service-provider router has an established LDP session with a neighbor, but the expected label-switched path is missing for an IGP route. Which issue should be investigated first?<\/b><\/p>\n

    \n
  1. <\/b> Whether the PIM RP is reachable<\/span><\/li>\n
  2. <\/b> Whether BGP MED is identical on all peers<\/span><\/li>\n
  3. <\/b> Whether the required FEC has an appropriate label binding and IGP reachability<\/span><\/li>\n
  4. <\/b> Whether the OSPF DR has changed<\/span><\/li>\n<\/ol>\n

    Correct Answer: 3. Whether the required FEC has an appropriate label binding and IGP reachability<\/b><\/p>\n

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

    An established LDP session does not automatically guarantee that every expected MPLS forwarding entry exists. LDP distributes labels for Forwarding Equivalence Classes (FECs), commonly based on IGP-reachable prefixes. If an expected LSP is missing, the engineer should verify that the destination prefix exists in the IGP and that an appropriate label binding has been learned or generated. The LIB and LFIB should then be examined to determine whether the label information has progressed from control plane to forwarding plane. PIM, BGP MED, and OSPF DR selection do not directly determine whether an LDP label is installed for a specific FEC.<\/span><\/p>\n

    Question 162. Which IS-IS feature allows a router to indicate that it should not be used as a transit path while it is recovering or synchronizing its routing information?<\/b><\/p>\n

      \n
    1. <\/b> Overload bit<\/span><\/li>\n
    2. <\/b> DIS election<\/span><\/li>\n
    3. <\/b> CSNP suppression<\/span><\/li>\n
    4. <\/b> Route Target<\/span><\/li>\n<\/ol>\n

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

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

      The IS-IS overload bit provides a mechanism for indicating that a router should generally not be used as a transit router. It is particularly useful during startup or recovery when the router’s link-state database may not yet be fully synchronized. Other routers can avoid selecting the overloaded router for transit traffic while still maintaining appropriate reachability to destinations associated with it. This behavior helps prevent traffic from being routed through a router before its routing information is ready. DIS election and CSNP mechanisms serve database and adjacency functions, while Route Targets belong to MPLS VPN route-distribution policy rather than IS-IS transit control.<\/span><\/p>\n

      Question 163. A BGP speaker receives several routes to the same prefix. After higher-priority attributes are equal, one route has a shorter AS_PATH than the others. Which route-selection behavior normally occurs?<\/b><\/p>\n

        \n
      1. <\/b> The longest AS_PATH is preferred<\/span><\/li>\n
      2. <\/b> AS_PATH is ignored when LOCAL_PREF is equal<\/span><\/li>\n
      3. <\/b> The route with the highest MED is preferred<\/span><\/li>\n
      4. <\/b> The route with the shorter AS_PATH is preferred<\/span><\/li>\n<\/ol>\n

        Correct Answer: 4. The route with the shorter AS_PATH is preferred<\/b><\/p>\n

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

        AS_PATH length is one of the attributes considered during BGP best-path selection. When earlier selection criteria such as Weight and LOCAL_PREF do not distinguish the candidate paths, BGP generally prefers the path with the shorter AS_PATH. A shorter path is normally interpreted as requiring traversal through fewer autonomous systems. However, AS_PATH length is not always the first deciding factor, and local policies can override the expected result through attributes such as LOCAL_PREF or Weight. Engineers should therefore inspect the complete BGP best-path decision process rather than assuming AS_PATH alone determines the selected route.<\/span><\/p>\n

        Question 164. An enterprise connects to two service providers and wants all routers inside its autonomous system to prefer one provider for outbound traffic. Which BGP attribute is normally appropriate?<\/b><\/p>\n

          \n
        1. <\/b> MED<\/span><\/li>\n
        2. <\/b> LOCAL_PREF<\/span><\/li>\n
        3. <\/b> AS_PATH prepending<\/span><\/li>\n
        4. <\/b> NEXT_HOP<\/span><\/li>\n<\/ol>\n

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

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

          LOCAL_PREF is designed to influence outbound path selection within an autonomous system. A higher LOCAL_PREF value is preferred, allowing an organization to consistently select one provider as its preferred exit path across its internal BGP routers. This attribute is propagated through iBGP and therefore supports coordinated outbound traffic engineering. AS_PATH prepending is more commonly used to influence how external networks select inbound paths toward the organization. MED can also influence path selection under particular conditions, but it is generally associated with communicating a preferred entry point to a neighboring AS. LOCAL_PREF is therefore the common mechanism for internal outbound preference.<\/span><\/p>\n

          Question 165. A provider is troubleshooting an MPLS L3VPN route that appears in MP-BGP but is not installed in the customer’s VRF. The route carries an RT that does not match the VRF’s import RT. What is the likely result?<\/b><\/p>\n

            \n
          1. <\/b> The route is automatically imported because the RD matches<\/span><\/li>\n
          2. <\/b> The route is imported into every VRF<\/span><\/li>\n
          3. <\/b> The route is not imported into that VRF<\/span><\/li>\n
          4. <\/b> The route is converted into an IPv4 global route<\/span><\/li>\n<\/ol>\n

            Correct Answer: 3. The route is not imported into that VRF<\/b><\/p>\n

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

            Route Targets determine whether VPN routes are eligible for import into a VRF. If the RT carried by an MP-BGP VPN route does not match any configured import RT for a particular VRF, that VRF normally will not import the route. The Route Distinguisher has a different purpose: it makes otherwise overlapping customer prefixes unique in the VPN address family. Therefore, a matching RD does not by itself cause a route to enter a VRF. When troubleshooting missing MPLS L3VPN routes, engineers should check the route’s RT attributes, VRF import policy, MP-BGP propagation, and VPN label information.<\/span><\/p>\n

            Question 166. An IS-IS router receives a CSNP that indicates another router has an LSP version newer than the local copy. What should the router do to synchronize its database?<\/b><\/p>\n

              \n
            1. <\/b> Restart the IS-IS process<\/span><\/li>\n
            2. <\/b> Disable the adjacency<\/span><\/li>\n
            3. <\/b> Ignore the newer sequence number<\/span><\/li>\n
            4. <\/b> Request the newer LSP using the appropriate PSNP mechanism<\/span><\/li>\n<\/ol>\n

              Correct Answer: 4. Request the newer LSP using the appropriate PSNP mechanism<\/b><\/p>\n

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

              IS-IS database synchronization uses CSNPs and PSNPs together. A CSNP provides information about the LSPs known to the sender, including sequence information. If a receiving router discovers that its local LSP is missing or older than the version indicated by the CSNP, it can use a PSNP to request the required information. The neighboring router can then provide the newer LSP. This mechanism allows IS-IS routers to maintain consistent link-state databases without restarting the routing process. Understanding LSP sequence numbers, CSNP summaries, and PSNP requests is useful when diagnosing incomplete or inconsistent IS-IS databases.<\/span><\/p>\n

              Question 167. A BGP route reflector receives a route from a client and reflects it to another client. Which mechanism helps prevent the route from looping through the same route-reflector cluster?<\/b><\/p>\n

                \n
              1. <\/b> CLUSTER_LIST<\/span><\/li>\n
              2. <\/b> LOCAL_PREF<\/span><\/li>\n
              3. <\/b> MED<\/span><\/li>\n
              4. <\/b> Weight<\/span><\/li>\n<\/ol>\n

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

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

                The CLUSTER_LIST attribute helps prevent routing loops involving BGP route reflectors. When a route reflector reflects a route, it adds its cluster ID to the CLUSTER_LIST. If a route reflector later receives a route containing its own cluster ID, it can recognize that the route has already passed through its cluster and reject it as a loop-prevention measure. ORIGINATOR_ID provides complementary protection by identifying the original BGP speaker. LOCAL_PREF, MED, and Cisco Weight influence route selection but are not the primary route-reflection cluster-loop prevention mechanisms. Correct use of cluster IDs is therefore important in networks with multiple route reflectors.<\/span><\/p>\n

                Question 168. A provider wants to make a particular BGP path less attractive to remote autonomous systems without changing the actual network topology. Which technique can artificially increase the advertised AS_PATH length?<\/b><\/p>\n

                  \n
                1. <\/b> Raising LOCAL_PREF<\/span><\/li>\n
                2. <\/b> AS_PATH prepending<\/span><\/li>\n
                3. <\/b> Lowering the BGP hold timer<\/span><\/li>\n
                4. <\/b> Enabling BFD<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 2. AS_PATH prepending<\/b><\/p>\n

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

                  AS_PATH prepending allows a BGP speaker to insert additional copies of its own AS number into the AS_PATH of an advertised route. This makes the path appear longer to external BGP decision processes. When relevant higher-priority attributes are equal, remote networks generally prefer a shorter AS_PATH, so prepending can make the selected path less attractive. It is commonly used for inbound traffic engineering. LOCAL_PREF primarily controls outbound path selection within an autonomous system, while BFD and BGP timers concern failure detection and session behavior. The effectiveness of AS_PATH prepending depends on the remote network’s routing policy and other BGP attributes.<\/span><\/p>\n

                  Question 169. A service-provider router uses MPLS LDP. Which table primarily contains label bindings learned or generated by the LDP control plane before forwarding entries are programmed?<\/b><\/p>\n

                    \n
                  1. <\/b> ARP table<\/span><\/li>\n
                  2. <\/b> OSPF LSDB<\/span><\/li>\n
                  3. <\/b> BGP RIB<\/span><\/li>\n
                  4. <\/b> Label Information Base (LIB)<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 4. Label Information Base (LIB)<\/b><\/p>\n

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

                    The Label Information Base (LIB) contains MPLS label bindings associated with FECs as learned or generated by the label-distribution control plane. LDP uses these bindings to build the information needed for MPLS forwarding. The LFIB is the forwarding-plane-oriented structure that contains the actual label operations used for packet forwarding. Therefore, when troubleshooting an LDP issue, comparing LIB and LFIB entries can help determine whether a control-plane label binding has successfully resulted in a forwarding entry. ARP, the OSPF LSDB, and the BGP RIB provide different types of information and do not replace the LIB for MPLS label bindings.<\/span><\/p>\n

                    Question 170. In OSPF, which LSA type is used by an ASBR to advertise external routes into a normal OSPF area?<\/b><\/p>\n

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

                      Correct Answer: 3. Type 5<\/b><\/p>\n

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

                      Type 5 LSAs are AS-external LSAs used to advertise routes redistributed into the OSPF autonomous system by an Autonomous System Boundary Router (ASBR). They are normally flooded throughout the OSPF domain, subject to area-specific restrictions. Type 3 LSAs carry inter-area network summaries, Type 4 LSAs describe reachability to an ASBR, and Type 2 LSAs are network LSAs originated by a DR on broadcast or NBMA segments. In an NSSA, external routes introduced inside the area are represented using Type 7 LSAs before eligible routes can be translated by an ABR into Type 5 LSAs.<\/span><\/p>\n

                      Question 171. A BGP router needs to advertise multiple paths for a prefix to improve path diversity and reduce path hiding caused by route reflection. Which capability should be considered?<\/b><\/p>\n

                        \n
                      1. <\/b> Add-Path<\/span><\/li>\n
                      2. <\/b> MED<\/span><\/li>\n
                      3. <\/b> Route dampening<\/span><\/li>\n
                      4. <\/b> Maximum-prefix<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1. Add-Path<\/b><\/p>\n

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

                        BGP Add-Path allows a speaker to advertise multiple paths for the same prefix rather than only its single selected best path. This can improve path diversity and help mitigate path-hiding effects in topologies using route reflectors. The sending and receiving BGP speakers must support and negotiate the appropriate Add-Path capability, and the number of paths advertised is controlled by configuration. MED and route dampening serve different purposes, while maximum-prefix limits the quantity of routes accepted from a neighbor. Add-Path is therefore particularly relevant when a service-provider design needs downstream routers to receive multiple usable paths for greater resilience or traffic-engineering flexibility.<\/span><\/p>\n

                        Question 172. A network operator configures an OSPF virtual link between two areas. What is the primary purpose of an OSPF virtual link?<\/b><\/p>\n

                          \n
                        1. <\/b> To replace all ABR functionality<\/span><\/li>\n
                        2. <\/b> To logically connect an area to the OSPF backbone through a transit area<\/span><\/li>\n
                        3. <\/b> To transport MPLS labels<\/span><\/li>\n
                        4. <\/b> To establish an eBGP session<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 2. To logically connect an area to the OSPF backbone through a transit area<\/b><\/p>\n

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

                          An OSPF virtual link provides a logical connection to the backbone Area 0 through a transit area. It is generally used when the physical topology does not provide a direct connection between an area and Area 0 but the design still requires that logical backbone connectivity. The endpoints must have appropriate reachability through the transit area, and the virtual link operates as a logical OSPF adjacency. Virtual links do not transport MPLS labels or establish BGP sessions. In modern designs, restructuring the area topology is often considered where practical, but understanding virtual-link behavior remains important for troubleshooting existing OSPF deployments.<\/span><\/p>\n

                          Question 173. A PIM-SM router receives a multicast packet on an interface that does not match the unicast routing path back toward the source. What mechanism identifies this condition?<\/b><\/p>\n

                            \n
                          1. <\/b> BGP best-path selection<\/span><\/li>\n
                          2. <\/b> OSPF DR election<\/span><\/li>\n
                          3. <\/b> Reverse Path Forwarding check<\/span><\/li>\n
                          4. <\/b> MPLS label swap<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 3. Reverse Path Forwarding check<\/b><\/p>\n

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

                            PIM multicast forwarding uses the Reverse Path Forwarding (RPF) check to verify that a multicast packet arrived through the interface the router considers correct for reaching the source. The router uses its unicast routing information to determine the expected reverse path. If the packet arrives through another interface, the RPF check fails and the packet is normally dropped. RPF is fundamental to preventing multicast forwarding loops and duplicate traffic. Troubleshooting an RPF failure should therefore include checking the unicast route to the source, routing preferences, interface state, and multicast state rather than focusing on BGP or MPLS label operations.<\/span><\/p>\n

                            Question 174. A provider configures BFD for a critical routing adjacency. Which characteristic distinguishes BFD from normal routing-protocol keepalive mechanisms?<\/b><\/p>\n

                              \n
                            1. <\/b> It is designed for rapid, protocol-independent failure detection<\/span><\/li>\n
                            2. <\/b> It selects the preferred BGP route<\/span><\/li>\n
                            3. <\/b> It assigns an MPLS VPN label<\/span><\/li>\n
                            4. <\/b> It replaces the underlying IGP<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 1. It is designed for rapid, protocol-independent failure detection<\/b><\/p>\n

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

                              Bidirectional Forwarding Detection (BFD) is designed to provide rapid detection of forwarding-path failures independently of the normal operation of a particular routing protocol. Routing protocols such as BGP, OSPF, and IS-IS can use BFD to receive faster failure indications and react accordingly. BFD does not replace the routing protocol’s role in route calculation, path selection, or route advertisement. Its primary function is fast liveliness detection. This makes it valuable in service-provider networks where reducing failure-detection time can significantly improve convergence. Proper interface and BFD configuration must still be verified because BFD operation depends on compatible parameters between endpoints.<\/span><\/p>\n

                              Question 175. A customer uses overlapping IPv4 address space with another customer. Which MPLS L3VPN mechanism allows both customers to use the same IPv4 prefix without ambiguity in the provider’s VPN routing table?<\/b><\/p>\n

                                \n
                              1. <\/b> LOCAL_PREF<\/span><\/li>\n

                              4. <\/b> Route Distinguisher<\/span><\/li>\n<\/ol>\n

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

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

                                The Route Distinguisher (RD) extends an IPv4 prefix into the VPNv4 address space so that otherwise identical customer prefixes can coexist uniquely. For example, two customers can both advertise 10.20.30.0\/24 while the provider represents the routes as distinct VPNv4 prefixes using different RDs. The RD provides uniqueness but does not decide which VRFs receive the route. Route Targets perform that import\/export policy function. This separation is important when troubleshooting MPLS L3VPNs because a route can be uniquely identified in VPNv4 while still being excluded from a particular VRF if its Route Target does not match the VRF’s import policy.<\/span><\/p>\n

                                Question 176. A service provider wants to protect a customer-facing BGP session from a route leak while allowing only the customer’s documented prefixes. Which combination provides both prefix validation and a route-count safeguard?<\/b><\/p>\n

                                  \n

                                  Correct Answer: 2. Inbound prefix filtering and BGP maximum-prefix<\/b><\/p>\n

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

                                  Inbound prefix filtering and BGP maximum-prefix provide complementary protection on customer-facing BGP sessions. A prefix list or route policy can identify exactly which prefixes the customer is authorized to advertise. Maximum-prefix then provides a quantity-based safeguard if the customer unexpectedly advertises a large number of routes. Together, these controls help reduce the impact of accidental route advertisements and routing leaks. MED does not perform prefix authorization, while PIM RPF is a multicast forwarding mechanism. BFD can improve failure detection but does not validate BGP prefixes. Combining policy-based filtering with route-count protection is a common service-provider operational practice.<\/span><\/p>\n

                                  Question 177. In Segment Routing, which SID type normally represents a node and provides reachability toward that node through the SR domain?<\/b><\/p>\n

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

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

                                    A Node SID represents a specific Segment Routing node and is normally associated with a prefix representing that node. When a packet is forwarded using a Node SID, the network follows the shortest path toward the identified node according to the relevant Segment Routing topology and routing information. An Adjacency SID instead identifies a particular adjacency or link, allowing more explicit path control. A Binding SID can represent an SR policy or segment list, while Anycast RP is a multicast concept rather than an SR SID type. Understanding the distinction between Node, Adjacency, and Binding SIDs is important when designing and troubleshooting SR policies.<\/span><\/p>\n

                                    Question 178.

                                      Correct Answer: 4. MPLS transport and VPN label forwarding entries<\/b><\/p>\n

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

                                      When a VPN route is present in MP-BGP and has been successfully imported into the destination VRF, the next troubleshooting step should include examining the MPLS forwarding plane. MPLS L3VPN traffic generally requires a transport label to reach the remote PE and a VPN label to identify the customer VRF or service route. Missing or incorrect LFIB entries, label bindings, or transport LSPs can prevent traffic from reaching the destination even though the control-plane route appears correct. Checking the PE and P routers’ MPLS forwarding information can therefore distinguish a control-plane route-distribution problem from a forwarding-plane label problem.<\/span><\/p>\n

                                        Correct Answer: 2. Route dampening<\/b><\/p>\n

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

                                        BGP route dampening is designed to reduce the impact of unstable routes that repeatedly flap. A route accumulates penalty based on instability, and when configured thresholds are reached, the route can be suppressed temporarily. As the penalty decays over time, the route can eventually become eligible again. Dampening is intended to reduce repeated propagation of unstable routing information, although its use and tuning require care because aggressive suppression can delay legitimate recovery. Add-Path, route reflection, and next-hop-self solve different BGP problems. When troubleshooting route instability, engineers should examine the actual flap source and not rely on dampening as a substitute for fixing the underlying cause.<\/span><\/p>\n

                                        Question 180. A router has two valid paths to the same BGP destination. One path has a higher LOCAL_PREF, while the other has a shorter AS_PATH. Which attribute is considered first in the relevant BGP best-path process?<\/b><\/p>\n

                                        4. <\/b> Router ID<\/span><\/li>\n<\/ol>\n

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

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

                                          LOCAL_PREF is considered before AS_PATH in the BGP best-path decision process. Therefore, when otherwise eligible routes have different LOCAL_PREF values, the route with the higher LOCAL_PREF is preferred before AS_PATH length becomes relevant. A shorter AS_PATH does not override a higher LOCAL_PREF simply because it contains fewer autonomous systems. This distinction is important when troubleshooting provider traffic-engineering policies because administrators may expect AS_PATH manipulation to influence a decision that is actually determined earlier by LOCAL_PREF. Reviewing BGP attributes in their decision-process order helps explain why a particular route is selected.<\/span><\/p>\n
