• Question 383:

  Refer to the exhibit.

  Router1: tacacs-server host 192.168.1.2 single-connectiontacacs-server key ciscotest

  What is the result of this configuration?

  A. Router 1 opens and closes a TCP connection to the TACACS+ server every time a user requires authorization.

  B. Router 1 and the TACACS+ server maintain one open connection between them only when network administrator is accessing the router with password ciscotest.

  C. Router 1 and the TACACS+ server maintain one open connection between them.

  D. Router 1 opens and closes a TCP connection to the TACACS+ server every time a user requires authentication.

  Correct Answer: C

  https://www.ccexpert.us/cisco-secure/configuring-tacacs-on-cisco-ios.html single-connection (Optional) Used to specify a single connection. Rather than have the router open and close a TCP connection to the daemon each time it must communicate, the single-connection option maintains a single open connection between the router and the daemon. This is more efficient because it allows the daemon to handle a higher number of TACACS operations.

• Question 384:

  RIP network 192.168.1.0/24 is redistributed in OSPF Area 1; both Area 1 and Area 2 are configured as NSSAs.

  Which three statements describe the OSPF behavior in this scenario? (Choose three.)

  A. Area 2 does not see the network 192.168.1.0/24 in its link-state database.

  B. Network 192.168.1.0/24 is advertised in a Type 7 LSA in Area 1.

  C. Network 192.168.1.0/24 is advertised in a Type 5 LSA in Area 0.

  D. Network 192.168.1.0/24 is advertised in a Type 7 LSA in Area 0.

  E. ABR between Area 0 and Area 2 converts network 192.168.1.0/24 to a Type 7 LSA.

  F. Network 192.168.1.0/24 is advertised in a Type 5 LSA in Area 2.

  Correct Answer: ABC

  Router 2 connects OSPF area 1 and area 0. Router 2 receives LSA type 1 from Router 1 in area 1. How many type 3 LSAs will be generated by Router 2 into area 0 to advertise all prefixes that are announced by the Router 1 LSA type 1 packet?

• Question 389:

  Refer to the exhibit.

  

  Which command group does a network administrator use to filter out R3 (3.3.3.3 subnet) from the R4 routing table?

  A. R4(config)# router ospf 1 distribute-list prefix-list filter in

  B. R2(config)# router ospf 1 distribute-list prefix-list filter out Fa0/1

  Correct Answer: A

• Question 390:

  Refer to the exhibit.

  

  A company is deploying IPv6 using a dual-stack approach. OSPFv2 is used for IPv4 routing and is redistributed into the BGP IPv4 address family. The network engineer also needs to enable OSPFv3 for IPv6 routing using the same design

  that is used for OSPFv2. All prefixes in the OSPFv3 database must be redistributed into the BGP IPv6 address family at router R2, but R3 does not receive the loopback 0 IPv6 address of R2 via BGP.

  Which action will fix this problem?

  A. redistribution of BGP routes into OSPFv3

  B. redistribution of OSPFv3 routes into BGP with include-connected

  C. mutual redistribution of OSPFv3 and BGP routes

  D. redistribution of connected OSPFv3 routes

  Correct Answer: B
