  B. The number of prefixes

  C. The redistribution points.

  D. The bandwidth and metrics of the links.

  Correct Answer: D

• Question 112:

  When designing fast convergence on a network using loop-free alternate, on which two basis can the next-hop routes be precomputed? (Choose two)

  A. Per neighbor

  B. Per network type

  C. Per link

  D. Per prefix

  E. Per failure type

  Correct Answer: CD

• Question 113:

  You are hired to assist an enterprise customer to design their global WAN network. A protected DWDM circuit with disjoint fiber routes and guaranteed restoration times is ordered to connect two hub sites. Which option is a BFD design consideration in relation to protected DWDM?

  A. BFD failure detection must be faster than DWDM restoration time

  B. The BFD hello timer must match the DWDM circuit restoration time

  C. BFD failure detection must be longer than DWDM restoration time

  D. BFD cannot be used with protected DWDM

  Correct Answer: C

• Question 114:

  Refer to the Exhibit.

  

  In which three Layers should you use nonstop Forwarding to reduce service impact in case of failure? (Choose three)

  A. Enterprise Edge

  B. Enterprise Core

  C. Service provider Edge

  D. Dual-attached sever Layer

  E. Enterprise Non-Routed Access Layer

  F. Enterprise Non-Routed Distribution Layer.

  Correct Answer: ABC

• Question 115:

  There is an MPLS-enabled link constantly flapping on an MPLS VPN network. Given that the network runs OSPF as the IGP protocol, which design mechanism will stabilize the network and avoid constant re-convergence?

  A. IP Event Dampening

  B. OSPF fast hellos

  C. IP SLA

  D. Partial SPF

  Correct Answer: A

• Question 116:

  Why is a redundant PIM stub router topology a bad network design decision?

  A. Multicast convergence takes long

  B. Multicast traffic duplication will occur

  C. It interferes with IGMP snooping

  D. It interfaces with PIM snooping

  Correct Answer: B

• Question 117:

  You are redesigning a high-speed transit network due to congestion-related issues. Which congestion avoidance mechanism can you apply to the existing network?

  A. NBAR

  B. FIFO

  C. WRED

  D. Rate-limit

  E. Policy-Based Routing

  Correct Answer: C

• Question 118:

  Refer to the exhibit.

  

  Transit traffic in this large enterprise campus network passes the eBGP core. Per security policy, traffic coming from AS 65444 destined for AS 65466 and vice-versa must pass through AS 65400. An audit discovers that traffic between 65444 and 65466 did not pass through 65400, instead it is communicating directly. How must you design BGP to ensure that the traffic from AS 65444 destined for AS 65466 passes through AS65400 on this broadcast network?

  A. Apply an ACL on AS 65466 to drop the direct traffic between AS 65444 and AS 65466

  B. Apply AS-path prepending on AS 65466 and AS 65444

  C. Apply next-hop self on both BGP neighbors on AS 65400

  D. Apply the MED attribute on the BGP session for AS 65444

  Correct Answer: C

• Question 119:

  Which mechanism provides fast path failure detection?

  A. Non-Stop Forwarding

  B. Carrier delay

  C. Graceful restart

  D. UDLD

  E. Fast hello packets

  F. iSPF

  Correct Answer: E

• Question 120:

  You are solving a design failure on a massive Hadoop cluster network that has an application with TCP incast behavior (also known as TCP Throughput collapse) affecting its many-to-one communications with packet loss at the last-hop

  network device.

  Which metric must be measured to ensure that the network provides the best performance for this application?

  A. Availability

  B. Bandwidth utilization

  C. Jitter values

  D. Buffer utilization

  Correct Answer: D
