Q371. 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 via R2. 

B. R2 does not have a route to in the routing table. 

C. The prefix becomes stuck-in-active on R4. 

D. R3 does not advertise to R4 anymore. 


Q372. Refer to the exhibit. 

A spoke site that is connected to Router-A cannot reach a spoke site that is connected to Router-B, but both spoke sites can reach the hub. What is the likely cause of this issue? 

A. There is a router doing PAT at site B. 

B. There is a router doing PAT at site A. 

C. NHRP is learning the IP address of the remote spoke site as a /32 address rather than a /24 address. 

D. There is a routing issue, as NHRP registration is working. 



If one spoke is behind one NAT device and another different spoke is behind another NAT device, and Peer Address Translation (PAT) is the type of NAT used on both NAT devices, then a session initiated between the two spokes cannot be established.

Q373. Which EIGRP configuration results in subsecond failover outside of the basic routing 

protocol convergence? 

A. bfd all-interfaces 

B. timers active-time disabled 

C. timers active-time 1 

D. timers nsf route-hold 20 


Q374. Which IP SLA operation type uses IP to measure the round-trip time between a router and a device? 


B. ICMP Echo 

C. ICMP Path Jitter 

D. UDP Jitter for VoIP 


Q375. Which two statements about VPLS are true? (Choose two.) 

A. Split horizon is used on PE devices to prevent loops. 

B. Spanning tree is extended from CE to CE. 

C. IP is used to switch Ethernet frames between sites. 

D. PE routers dynamically associate to peers. 

E. VPLS extends a Layer 2 broadcast domain. 

Answer: A,E 

Q376. Which two application protocols require application layer gateway support when using NAT on a Cisco router? (Choose two.) 





E. POP3 

Answer: A,C 


Drag and drop each MLPPP command on the left to the function it performs on the right. 


Q378. An access switch at a remote location is connected to the spanning-tree root with redundant uplinks. A network engineer notices that there are issues with the physical cabling of the current root port. The engineer decides to force the secondary link to be the desired forwarding root port. Which action accomplishes this task? 

A. Adjust the secondary link to have a lower priority than the primary link. 

B. Change the link type to point-to-point. 

C. Apply a BPDU filter on the primary interface of the remote switches. 

D. Enable Rapid Spanning Tree to converge using the secondary link. 


Q379. Which statement describes the function of rekey messages? 

A. They prevent unencrypted traffic from passing through a group member before registration. 

B. They refresh IPsec SAs when the key is about to expire. 

C. They trigger a rekey from the server when configuring the rekey ACL. 

D. They authenticate traffic passing through a particular group member. 



Rekey messages are used to refresh IPsec SAs. When the IPsec SAs or the rekey SAs are about to expire, one single rekey message for a particular group is generated on the key server. No new IKE sessions are created for the rekey message distribution. The rekey messages are distributed by the key server over an existing IKE SA. Rekeying can use multicast or unicast messages.

Q380. Which component of MPLS architecture uses protocols such as the label distribution protocol and tag distribution protocol to exchange labels? 

A. control plane 

B. data plane 

C. forwarding plane 

D. routing plane
