Cisco Cisco Certifications 352-001 Questions & Answers

• Question 51:

  What are two base components of both a source-based remotely triggered black hole and a destination-based remotely triggered black hole filtering solution? (Choose two.)

  A. NetFlow

  B. static route withthe next hop pointing to the Null0 interface

  C. infrastructure access list

  D. triggered IBGP update setting next hop to a predetermined, unused IP address

  E. uRPF

  Correct Answer: BD

• Question 52:

  You work for a large enterprise network that spans many remote locations and uses EIGRP as its only routing protocol. Recently, the network grew too rapidly and it is having a lot of SIA problems, which impact the company business.

  In which two ways should you redesign the network to solve this problem? (Choose two.)

  A. Eliminate the use of secondary networks.

  B. Implement EIGRP Wide Metrics

  C. Eliminate duplicate router IDs.

  D. Implement route summarization.

  E. Implement EIGRP Stub on remote locations.

  Correct Answer: DE

• Question 53:

  

  Refer to the exhibit. Company A migrated from Frame Relay WAN to Metro-Ethernet E-LAN service. Router B and C have only eBGP neighbor adjacency with router A using their Metro-Ethernet IP addresses. What happens when host E sends a packet to host F?

  A. Packet goes from router B to A and C.

  B. Packet is dropped by router B.

  C. Packet goes from router B to C.

  D. Packet goes from router B to Aand is dropped by router A due to the split-horizon rule.

  Correct Answer: A

• Question 54:

  What is the advantage of using a router instead of a switch when implementing Hierarchical VPLS (H-VPLS) CE devices?

  A. MAC addresses on the entire broadcast domain are hidden from PEs, allowing for batter scalability

  B. It is easier to troubleshoot.

  C. Layer 3 equal-cost multipath can be used with redundant connections

  D. Layer 2 requires a full-mesh network

  Correct Answer: A

• Question 55:

  A service provider plans on implementing IPv6 using 6PE. What are two drawbacks of the 6PE approach? (Choose two.)

  A. The MPLS routers should have IPv6 enabled before they can respond to ICMPv6 messages.

  B. The label allocation modeis per-prefix so the label tablegrows as the BGP table increases.

  C. A single RIB and FIB is required for each connected customer so scalability issues can arise in the future.

  D. It is a disruptive way to introduce IPv6 into an existing MPLS service.

  Correct Answer: AB

• Question 56:

  Which design criteria drives the selection of G.8032 in an ISP network design?

  A. To gradually degrade the Ethernet rings' performance when it becomes saturated.

  B. To make full use of Ethernet rings' redundant paths.

  C. To achieve fast failover between two upstream Ethernet ring paths to the network core.

  D. To prevent loops on Ethernet rings.

  Correct Answer: D

• Question 57:

  

  Refer to the exhibit. This smart city has decided to deploy a converged network for video surveillance and applications for utility services. These new applications are delay-sensitive and require strict convergence times of less than 50 milliseconds. The network is expected to have up to 50 intermediate distribution frames per ring. Which protocol provides less than 50 milliseconds convergence?

  A. G8032

  B. STP

  C. G 8031

  D. RSTP

  Correct Answer: A

• Question 58:

  A service provider must provide Internet connectivity to an MPLS Layer 3 VPN customer. Which solution allows this customer to have Internet access?

  A. Implement a global default route with a next hop in the VRF late on PE

  B. Implement policy-based routing between PE and CE

  C. Implement a default route in the VRF with a next hop in the global routing table of PE

  D. Implement destination NAT between the VRF and the global RIB of PE

  Correct Answer: C

• Question 59:

  A service provider wants to use a controller to automate the provisioning of service function chaining.

  Which two overlay technologies can be used with EVPN MP-BGP to create the service chains in the data center?

  A. VXLAN

  B. MPLS L2VPN

  C. Provider Backbone Bridging EVPN

  D. 802.1Q

  Correct Answer: A

• Question 60:

  Which aspect is a significant disadvantage of containers?

  A. Security

  B. Time to deploy

  C. Inefficiency

  D. Reduced operational overhead

  E. Resource consumption

  Correct Answer: A
