Cisco Cisco Certifications 352-001 Questions & Answers

• Question 531:

  A. Deploy MPLS traffic engineering and modify the path using the preferred path.

  B. Deploy MPLS traffic engineering and modify the path using auto-route, static routing, or PBR.

  C. Create an MPLS traffic engineering tunnel and modify the path using a static route.

  Correct Answer: A

• Question 532:

  You are designing a Group Encrypted Transport virtual private network solution for an existing branch network. The existing network has the following characteristics:

  50 remote sites (with an additional 30 remote sites expected over the next 3 years)

  Connectivity between all sites is via Multiprotocol Label Switching Layer 3 virtual private network service from a single provider

  Open Shortest Path First is the routing protocol used between provider edge and customer edge routers

  The customer edge routers will become group members performing the encryption between sites

  Which additional routing protocol would you use for the overlay routing between the group members?

  A. Open Shortest Path First (with a different process ID)

  B. Enhanced Interior Gateway Routing Protocol

  C. No additional protocol is necessary.

  D. External Border Gateway Protocol

  E. Routing Information Protocol Version 2

  F. Next Hop Resolution Protocol

  Correct Answer: C

• Question 533:

  A service provider wants to maximize forwarding memory, routing memory, and CPU resources on PE devices for enterprise customers that have very few sites (two to three) and a large number of prefixes (several thousand).

  Which service should the service provider offer these customers?

  A. VPWS

  B. VPLS

  C. L3VPNs (RFC 2547-based)

  D. InterAS L3VPN

  Correct Answer: A

• Question 534:

  You are tasked with implementing a 1000-phone remote access solution, where phones will traverse a WAN edge router. Assuming all of the following features are supported in a hardware- assisted manner, which of the following will have the most detrimental impact on the delay of the packet?

  A. encryption

  B. stateful firewall

  C. MPLS encapsulation

  D. GRE encapsulation

  Correct Answer: A

• Question 535:

  When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two.)

  A. Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.

  B. Serialization delay depends not only on the line rate of the interface but also on the size of the packet.

  C. Serialization delays are invariable because they depend only on the line rate of the interface.

  D. Serialization delays are variable because they depend only on the size of the packet being serialized.

  E. Serialization delay is the time required to transmit the packet on the physical media.

  Correct Answer: BE

• Question 536:

  The network administrator of a branch office network has decided to deploy Unicast RPF at the access layer.

  He insists that the design must guarantee that all the packets arriving on the router interfaces are assigned to the same interface subnet.

  Which mode of Unicast RPF would you recommend as the lead network designer?

  A. uRPF strict mode

  B. uRPF loose mode

  C. uRPF VRF mode

  D. RPF feasible mode

  Correct Answer: A

• Question 537:

  Which two aspects are considered when designing a dual hub, dual DMVPN cloud topology? (Choose two.)

  A. recommended for high availability

  B. requires all sites to have dual Internet connections

  C. spoke-to-spoke traffic will transit the hub unless spokes exchange dynamic routing directly

  D. hub sites must connect to both DMVPN clouds

  E. will only work with single-tier headend architecture

  Correct Answer: AE

• Question 538:

  Refer to the exhibit.

  

  Will traffic sourced from router A and destined for a host on network 10.1.1.0/24 always take the optimal path to that host?

  A. No, if router A chooses to forward traffic destined to a host on the 10.1.1.0/24 network to router B, it will take a less than optimal path to reach its destination.

  B. Yes, router A has enough information to always direct traffic to router C when forwarding traffic to a host on the 10.1.1.0/24 network.

  C. Yes, router B will forward the traffic towards 10.1.1.0/24 correctly, if router A chooses that path.

  D. It doesn't matter which path to a host on 10.1.1.0/24 router A chooses, through router B or router C, since they are equal in cost.

  E. It depends on the routing protocol.

  Correct Answer: A

• Question 539:

  A company is planning to connect its 30 sites with a VPLS WAN backbone. A router at each site should establish neighborships with all other routers using the OSPF routing protocol. Which three points must be considered regarding DR and BDR when different router platforms are used? (Choose three.)

  A. It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR.

  B. If the IP OSPF priority is the same for all routers, the highest loopback IP address and router ID will decide which routers will take the DR and BDR role during the selection process.

  C. To select the DR and BDR, the IP OSPF priority must be set to a higher value than the default value at the DR and BDR during the selection process.

  D. To select the DR and BDR, the IP OSPF priority must be set to a lower value than the default value at the DR and BDR during the selection process.

  E. The role for the DR and BDR will be selected when a new OSPF router comes up.

  F. To force two routers to become a DR and a BDR, the IP OSPF priority can be set to zero at all other OSPF routers.

  Correct Answer: ABF

• Question 540:

  You have designed a network to support two offices connected by a T1. Your router serial interfaces will be configured with encapsulation PPP. What will happen to your EIGRP neighbors if there is an LCP failure once your network is implemented?

  A. Your neighbors will drop after the EIGRP timers expire.

  B. Your neighbors will stay up because the link has not gone down.

  C. Your neighbors will drop immediately.

  D. Your neighbors will drop and EIGRP will begin the query process.

  Correct Answer: D
