• Question 752:

  Refer to the exhibit

  

  The enterprise users fail to authenticate with the TACACS server when a direct fiber link fails between RB and RD. The NOC team observes:

  Users connected on AS65201 fail to authenticate with TACACS server 192.168.1.1.

  Users connected on AS65101 successfully authenticate with TACACS server 192.168.1.1.

  All AS65101 and AS65201 users are configured to authenticate with the TACACS server.

  Which configuration resolves the issue?

  A. RC(config)# ip prefix-list Customer seq 5 permit 192.168.30.1/32
  B. RC(config)#router bgp 65101 RC(config-router)# neighbor 10.0.0.18 prefix-list Customer in
  C. RF(config)#no ip prefix-list Customer seq 5 deny 192.168.1.1/32
  D. RF(config)#router bgp 65201 RF(config-router)# neiahbor 10.0.0.17 prefix-list Customer out
  C. RF(config)#no ip prefix-list Customer seq 5 deny 192.168.1.1/32

• Question 753:

  Which of the following statements is NOT true of NPTv6?

  A. is transport agnostic
  B. translates the entire IPv6 address to another IPv6 address
  C. is check sum neutral
  D. translates only the IPv6 prefix
  B. translates the entire IPv6 address to another IPv6 address

  ---

  Network Prefix Translation (NPTv6) is a stateless method of translating the prefix of a received IPv6 address to another prefix without changing the host portion of the IPv6 address. Some of its characteristics are:

  It supports both transports that perform checksums on the IP header and those that do not. It provides a 1 to 1 relationship between the inside and outside prefixes.

  It translates only the prefix, and not the entire address.

  Objective:

  Infrastructure Services

  Sub-Objective:

  Describe IPv6 NAT

• Question 754:

  An associate configured a serial connection on Router1 to use PPP with authentication. You execute the debug ppp negotiation command on the router and receive the following output:

  

  Which of the following statements are true? (Choose all that apply.)

  A. the credentials are being sent in clear text
  B. the connection failed
  C. the peer's name is Router2
  D. the authentication failed
  A. the credentials are being sent in clear text
  C. the peer's name is Router2

  ---

  The peer router's name is Router2 and the authentication method is PAP, which transmits the credentials in clear text. The peer name can be seen in the following line of output:

  *Mar 3 00:06:17.536: Se1/1 PAP: Authenticating peer ROUTER2

  The authentication protocol used is seen in the following line of output:

  *Mar 3 00:06:16.868: Se1/1 LCP: AuthProto PAP (0x0304C023)

  The connection process and authentication process are two separate processes and in this case both succeeded. First the connection completed as indicated by the following line of output:

  *Mar 3 00:06:17.260: Se1/1 LCP: State is Open

  Then later the authentication succeeded, as indicated by this line at the end of the output:

  *Mar 3 00:06:17.584: Se1/1 PPP: Phase is UP

  Objective:

  Layer 2 Technologies

  Sub-Objective:

  Configure and verify PPP

• Question 755:

  Refer to the exhibit.

  

  An administrator is setting up above shown routers to enable MVPN with mGRE mode. What would be the recommended interface configuration that must be done by the engineer to make it to work?

  A. interface Tunnel0 description mGRE - DMVPN Tunnel ip address 10.0.0.1 255.255.255.0 ip nhrp map multicast dynamic ip nhrp network-id 1 tunnel source 10.0.0.1 tunnel mode IPSec multipoint
  B. interface Tunnel0 description mGRE - DMVPN Tunnel ip address 10.0.0.1 255.255.255.0 ip nhrp map multicast dynamic ip nhrp network-id 1 tunnel source 10.0.0.1 tunnel mode gre multipoint
  C. interface Tunnel0 description mGRE - DMVPN Tunnel ip address 10.0.0.1 255.255.255.0 ip nhrp network-id 1 tunnel source 172.17.0.1 tunnel mode IPsec multipoint
  D. interface Tunnel0 description mGRE - DMVPN Tunnel ip address 10.0.0.1 255.255.255.0 ip nhrp map multicast dynamic ip nhrp network-id 1 tunnel source 10.0.0.1 tunnel destination 172.17.0.2 tunnel mode IPsec multipoint
  C. interface Tunnel0 description mGRE - DMVPN Tunnel ip address 10.0.0.1 255.255.255.0 ip nhrp network-id 1 tunnel source 172.17.0.1 tunnel mode IPsec multipoint

• Question 756:

  Refer to the exhibit. An engineer must advertise LAN network 192.168.1.0 of router A to router B through OSPF. The engineer notices that router B was configured, but the LAN network of router A is not in the routing table of router B. Which configuration on router A resolves the problem?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 757:

  Refer to the exhibit.

  

  Refer to the exhibit. The network administrator configured VRF lite for customer A. The technician at the remote site misconfigured VRF on the router. Which configuration will resolve connectivity for both sites of customer_a?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

  ---

  From the exhibit, we learned:

  +

  VRF customer_a was exported with Route target (RT) of 1:1 so at the remote site it must be imported with the same RT 1:1.

  +

  VRF customer_a was imported with Route target (RT) of 1:1 so at the remote site it must be exported with the same RT 1:1.

  Therefore at the remote site we must configure the command "route-target both 1:1" (which is equivalent to two commands "route-target import 1:1" and "route-target export 1:1".

• Question 758:

  What is an MPLS LDP targeted session?

  A. session between neighbors that are connected no more than one hop away
  B. LDP session established between LSRs by exchanging TCP hello packets
  C. label distribution session between non-directly connected neighbors
  D. LDP session established by exchanging multicast hello packets
  C. label distribution session between non-directly connected neighbors

• Question 759:

  A network engineer receives a fault ticket about traffic drops from BANK SITE to BANK

  Users can reach BANK SITE Y from router RA as a source. Routers RB and RD are acting as route reflectors.

  Which configuration resolves the issue?

  A. RC(config)#router bgp 65201 RC(config-router)#neighbor 10.10.10.4 route-reflector-client
  B. RF(config)#router bgp 65201 RF(config-router)#neighbor 10.10.10.6 route-reflector-client
  C. RC(config)#router bgp 65201 RC(config-router)#neighbor 10.10.10.2 route-reflector-client
  D. RB(config)router bgp 65201 RB(config-router)#neighbor 10.10.10.3 route-reflector-client
  A. RC(config)#router bgp 65201 RC(config-router)#neighbor 10.10.10.4 route-reflector-client
