• Question 11:

  What is an advantage of placing the IS-IS flooding domain boundary at the core Layer in a three-layer hierarchical network?

  A. The L1 and L2 domains can easily overlap

  B. The L2 domain is contained and more stable

  C. It can be applied to any kind of topology

  Correct Answer: A

• Question 12:

  Refer to the exhibit.

  

  As part of a redesign project, you must predict multicast behavior. What is the resultant multicast traffic receiving on the shared tree( , G), if it is received on the LHR interface indicated?

  A. It is dropped due to an unsuccessful RPF check against the multicast receiver

  B. It is switched due to a successful RPF check against the routing table

  C. It is switched given that no RPF check is performed

  D. It is dropped due to an unsuccessful RPF check against the multicast source

  Correct Answer: B

  A. SPAN monitor ports

  B. passive taps

  C. IP NBAR

  D. NetFlow

  Correct Answer: C

• Question 15:

  A. Fate sharing

  B. CPU resource allocation

  C. Congestion control

  D. Security

  E. Bandwidth allocation

  Correct Answer: A

• Question 16:

  You are designing the QoS features for a large enterprise network that includes DMVPN. In which situation should you use the QoS pre-classify feature?

  A. When you are marking packets with the ToS bits

  B. When the QoS policy cannot be based on DSCP bits

  C. When you are marking packets with the DSCP bits

  D. When your service provider requires the DSCP bits be set

  Correct Answer: B

• Question 17:

  A BGP route reflector in the network is talking longer than expected to converge during network changes. Troubleshooting has shown that the router cannot handle all the TCP acknowledgements during route updates. Which action can be performed to tune device performance?

  A. Increase the size of the large buffers

  B. Decrease the size of the small buffers

  C. Increase the keepalive timers for each BGP neighbor

  D. Increase the size of the hold queue

  Correct Answer: D

• Question 18:

  Which mechanism enables small, unmanaged switches to plug into ports of access switches without risking switch loops?

  A. PortFast

  B. UDLD

  C. Root guard

  D. BPDU guard

  Correct Answer: C

• Question 19:

  You are redesigning a single-level IS-IS network with 500 routers, which have short-haul and long-haul links Most of the time the routing domain is stable, but periodically interfaces on long-haul links bounce for a short period of time , causing 10 to 20 flaps in a few minutes. The probable cause is local road construction. Although fast convergence important, the client has concerns about taxing CPU cycles on the older routing platforms. What change should you recommend that both protects the CPU of the older routers during the short periods of excessive flapping, yet does not have an impact on fast convergence for all interface failures?

  A. Modify hello timers on routers with short-haul links

  B. Implement LSP generation throttling on routers with long-haul links

  C. Modify the length of time than an LSP remains in the router database without being refreshed on all routers

  D. Implement a delay between successive IS-IS LSP packet transmissions on routers with long-haul links

  Correct Answer: D

• Question 20:

  The cloud service provider CSP is planning to launch five data centers in Egypt, United Arab Emirates, Saudi Arabia, Qatar and Turkey. CSP is looking for VLAN extension and DCIs between these five data centers to allow for software replication, where original and backup VMs must be on the same subnet. Which tunneling technology must they use?

  A. VPLS

  B. IPsec VPN

  C. VPWS

  D. L2TPv3

  Correct Answer: A
