• Question 92:

  Which two statements about Layer 3 MPLS VPN are true? (Choose two.)

  A. The virtual routing and forwarding table is separate from the global routing table that exists on PE routers. Routes are injected into the VRF from the CE-PE routing protocols for that VRF and any MP- BGP announcements that match the defined VRF RTs.
  B. Multiprotocol Border Gateway Protocol is run between PE and CE routers to exchange customer prefixes in a VPNv4 format.
  C. A customer edge router peers at Layer 3 to the provider edge. The PE-CE interface runs either a dynamic routing protocol (eBGP, RIPv2, EIGRP, OSPF) or a static routing protocol (Static, Connected).
  D. VPNv4 address is the combination of the RT and customer IPv4 prefix. These VPNv4 prefixes are passed in MP-BGP.

• Question 93:

  Which two statements regarding the IS-IS DIS election process are true? (Choose two.)

  A. L1 routers on a broadcast network only establish adjacencies with the DIS.
  B. If the DIS becomes unavailable the backup DIS is promoted to DIS.
  C. Adding a router with a higher priority than the current DIS will result in the new router becoming DIS.
  D. Separate L1 and L2 election processes are held on a brodcast network.
  E. A priority of 0 will prevent a router from becoming a DIS.
  F. If there is a tie based on priority, the router whose attached interface has the lowest MAC address becomes the DIS.
  C. Adding a router with a higher priority than the current DIS will result in the new router becoming DIS.
  D. Separate L1 and L2 election processes are held on a brodcast network.

  Election of the DIS On a LAN, one of the routers elects itself the DIS, based on interface priority (the default is 64). If all interface priorities are the same, the router with the highest subnetwork point of attachment (SNPA) is selected. The SNPA is the MAC address on a LAN, and the local data link connection identifier (DLCI) on a Frame Relay network. If the SNPA is a DLCI and is the same at both sides of a link, the router with the higher system ID becomes the DIS. Every IS-IS router interface is assigned both a L1 priority and a L2 priority in the range from 0 to 127. The DIS election is preemptive (unlike OSPF). If a new router boots on the LAN with a higher interface priority, the new router becomes the DIS. It purges the old pseudonode LSP and floods a new set of LSPs.

• Question 94:

  What is the effect of changing DMT interleaved delay from 3 milliseconds to 15 milliseconds?

  C. Latency is increased, but faster error correction occurs.
  D. Fewer ATM PVCs can be provisioned on DSL line.
  C. Latency is increased, but faster error correction occurs.

  A. IGMP must be enabled for the client.
  B. R4 must be the DR on the R4-R6 segment.
  C. RP announcements have no multicast routing table entry.
  D. The RP must be reachable via Fa0/0.
  E. A static mroute must be configured to point to RP via Fa0/1 on R4.
  D. The RP must be reachable via Fa0/0.

• Question 96:

  What are the differences between LLQ and CBWFQ? (Choose two.)

  A. LLQ priority queue bandwidth is policed with a congestion aware policer.
  B. With LLQ, bandwidth allocations for the priority queue and all the CBWFQ queues are configured using the priority command.
  C. LLQ does not support WFQ on the default traffic class (class-default).
  D. LLQ supports the addition of strict priority queuing.
  E. LLQ is configured using MQC and CBWFQ is configured using the fair-queue command.
  A. LLQ priority queue bandwidth is policed with a congestion aware policer.
  D. LLQ supports the addition of strict priority queuing.

  The Private Network-to-Network Interface (PNNI) is a link-state routing protocol used in ATM networks. PNNI is similar to the open shortest path first (OSPF) used for IP routing. PNNI is a suite of network protocols that can be used to discover an ATM network topology, create a database of topology information, and route calls over the discovered topology. PNNI is a link-state routing protocol, which means that the protocol collects information about the current state of links and nodes in the network to build a network database. The PNNI network database can be used to determine the network structure and the current state of network components. To build the PNNI network database, each PNNI node must receive topology information from all the other devices in the network. To keep the database current, the node must receive regular updates from other nodes.

  C. It is generated by ABR and indicates reachability to itself.
  D. It is generated by ABR and indicates the reachability to an ASBR located in another area.
  E. It is generated by an ASBR and indicates the reachability to an ABR.
  D. It is generated by ABR and indicates the reachability to an ASBR located in another area.

• Question 100:

  Which two statements best describe the functionality of the BGP graceful restart capability? (Choose two.)

  B. The peer router immediately removes the BGP routes that it learned from the restarting router from its BGP routing table.
  C. The restarting router does not remove any stale prefixes after the timer for stale entries expires.
  D. The router establishes BGP sessions with other routers and relearns the BGP routes from other routers that are also capable of graceful restart.

When the neighboring routers send end-of-RIB messages to indicate that they are done sending updates, the restarting router starts sending its own updates.
  E. The restarting router removes any stale prefixes after the timer for stale entries expires.
