Cisco 351-001 Online Questions & Answers

• Question 941:

  Which field is specific to the OPSFv3 packet header, as opposed to the OSPFv2 packet header?

  A. checksum
  B. router ID
  C. AuType
  D. instance ID
  D. instance ID

  ---

  In OSPFv3, Instance ID is a new field that is used to have multiple OSPF process' instance per link. By default it is 0 and for any additional instance it is increased, instance ID has local link significance only. OSPFv3 routers will only become neighbors if the instanceIDs match. It is thus possible to have multiple routers on a broadcast domain and all run Ospfv3 but not all of them becoming neighbors.

• Question 942:

  Which two statements about path selection are true? (Choose two.)

  A. If there are multiple equal matches between OSPF processes, the path with the lowest OSPF PID is chosen.
  B. If the backdoor command is configured on a BGP network, the route is advertised with an AD of 20.
  C. If an OSPF E2 route has an AS of 90, that path is preferred over an OSPF IA route with an AD of 110.
  D. If there are multiple equal matches between the same protocols on an EIGRP network, the preferred path will be EIGRP with the highest AS.
  E. If IS-IS has multiple routes with the same prefix-length, it will prefer Level 1 routes over Level 2 routes.
  A. If there are multiple equal matches between OSPF processes, the path with the lowest OSPF PID is chosen.
  E. If IS-IS has multiple routes with the same prefix-length, it will prefer Level 1 routes over Level 2 routes.

• Question 943:

  Which protocol uses a proprietary 2-byte Type field for multiple protocol support?

  A. HDLC
  B. PPP
  C. CHAP
  D. PAP
  A. HDLC

• Question 944:

  Refer to the exhibit.

  

  All routers are running EIGRP and the network has converged. R3 and R4 are configured as EIGRP Stub. If the link between R1 and R3 goes down, which statement is true?

  A. R1 sends traffic destined to 192.168.0.100 via R2.
  B. R2 does not have a route to 192.168.0.0/24 in the routing table.
  C. The prefix 192.168.0.0/24 becomes stuck-in-active on R4.
  D. R3 does not advertise 192.168.0.0/24 to R4 anymore.
  B. R2 does not have a route to 192.168.0.0/24 in the routing table.

• Question 945:

  Refer to the exhibit.

  

  With these configurations for R1 and R2, which statement about PPP authentication is true?

  A. Authentication fails because R1 is missing a username and password.
  B. R2 responds with the correct authentication credentials.
  C. R2 requires authentication from R1.
  D. R1 requires authentication from R2.
  C. R2 requires authentication from R1.

  ---

  Only R2 is configured with the "PPP authentication PAP" command so it requires authentication from R1, but R1 does not require authentication from R2.

• Question 946:

  DRAG DROP

  Drag each SNMP term on the left to the matching definition on the right.

  Select and Place:

  

  

• Question 947:

  What is the destination address of an IGMPv2 general membership query?

  A. 224.0.0.1
  B. 224.0.1.1
  C. 224.0.0.2
  D. the multicast group address
  A. 224.0.0.1

• Question 948:

  Refer to the exhibit.

  

  Which prefixes will appear in the EIGRP topology table?

  A. 10.0.0.0/8, 172.16.1.0/24, 192.168.0.0/16
  B. 10.1.1.0/24, 10.1.2.0/24, 172.16.1.0/26, 192.168.1.0/26, 192.168.2.0/26

  D. 10.1.1.1/24, 10.1.2.1/24, 172.16.1.1/26, 172, 192.168.1.1/26, 192.168.2.1/26
  B. 10.1.1.0/24, 10.1.2.0/24, 172.16.1.0/26, 192.168.1.0/26, 192.168.2.0/26

  B. In Bidir-PIM, sources register to RP as in PM SM.
  C. The PIM DM flood and prune process is repeated every five minutes.
  D. PIM SM mode, by default, always forwards multicast traffic on shared tree.
