Cisco CCNP Enterprise 300-410 Questions & Answers

• Question 271:

  Refer to the exhibit.

  

  Router R1 peers with two ISPs using static routes to get to the internet. The requirement is that R1 must prefer ISP-A under normal circumstances and failover to ISP-B if the connectivity to ISP-A is lost. The engineer observes that R1 is load balancing traffic across the two ISPs

  Which action resolves the issue by sending traffic to ISP-A only with failover to ISP-B?

  A. Configure OSPF between R1. ISP-A. and ISP-B for dynamic failover if any ISP link to R1 fails

  B. Configure two static routes on R1. one pointing to ISP-A and another pointing to ISP- B with 222 admin distance

  C. Change the bandwidth of the interface on R1 so that interface to ISP-A has a higher value than the interface to ISP-B

  D. Configure two static routes on R1. one pointing to ISP-B with more specific routes and another pointing to ISP-A with summary routes

  Correct Answer: B

  ISP1) ip route 0.0.0.0 0.0.0.0 200.0.0.1

  ISP2) ip route 0.0.0.0 0.0.0.0 90.0.0.1 222 (AD static float)

• Question 272:

  Refer to the exhibit R1 cannot receive the R2 Interfaces with individual prefixes.

  

  What must be reconfigured to advertise R2 Interfaces to R1?

  A. EIGRP process on R2 by removing the stub command Keyword summary

  B. interface FastEthernet0/1 on R2 with an EIGRP summary for all three loopback prefixes

  C. EIGRP process on R2 with the command stub summary receive-only

  D. ElGRP process on R2 with the command stub summary connected

  Correct Answer: D

• Question 273:

  What must a network architect consider for RTs when planning for a single customer full-mesh VPN m an MPLS Layer 3 network?

  A. RT must be globally unique within the same VPN

  B. RT must be globally identical within the same VPN

  C. RT values must be Afferent from the RD values in the same VPN

  D. Each RT value must be identical to an RD value within the same VPN.

  Correct Answer: B

• Question 274:

  What action is performed for untagged outgoing labels in an MPLS router?

  A. Convert the incoming MPLS packet to an untagged packet and then do a FIB lookup

  B. Convert the incoming MPLS packet to an untagged packet and then do a RIB lookup.

  C. Convert the untagged packet to a labeled packet and forward it to the next router

  D. Convert the incoming MPLS packet to an IP packet and forward it to the next router.

  Correct Answer: C

• Question 275:

  A newly Installeo router starts establishing an LDP session from another MPLS router to which it is not directly connected. Which LDP message type responds by target router to the Initiating router using UDP protocol?

  A. notification message

  B. session message

  C. extended discovery message

  D. advertisement message

  Correct Answer: C

• Question 276:

  Which rouler takes an active role between two LDP neighbors when initiating LDP session negotiation and LDP TCP connection establishment?

  A. with the higher IP address

  B. with the larger number of LDP TCP neighbors

  C. with the lowest IP address

  D. with one interface in the MPLS backbone

  Correct Answer: A

• Question 277:

  A network administrator is troubleshooting a failed AAA login issue on a Cisco Catalyst c3560 switch. When the network administrator tries to log in with SSH using TACACS+ username and password credentials, the switch is no longer authenticating and is failing back to the local account. Which action resolves this issue?

  A. Configure ip tacacs source-interface GigabitEthernet 1/1

  B. Configure ip tacacs source-ip 192.168.100.55

  C. Configure ip tacacs-server source-ip 192.168.100.55

  D. Configure ip tacacs-server source-interface GigabitEthernet 1/1
