Cisco Cisco Certifications 352-001 Questions & Answers

• Question 291:

  Which option describes an advantage of UDLD?

  A. It makes the port go immediately into the forwarding state after being connected.

  B. It prevents switch loops by detecting one-way communications on the physical port.

  C. It prevents switched traffic from traversing suboptimal paths on the network.

  D. It prevents switch loops caused by uni-directional point-to-point link condition on Rapid PVST+ and MST.

  E. It does not generate a spanning-tree topology change upon connecting and disconnecting a station on a port.

  F. It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops.

  Correct Answer: B

• Question 292:

  Refer to the exhibit.

  A. on the OSPF links of all ABR routers

  B. on the OSPF links of all ASBR routers

  C. on the OSPF links of all backbone routers

  D. on the routing process of all ABR routers

  F. on the routing process of all backbone routers

  Correct Answer: DE

• Question 294:

  Which technique can be used to deploy IPv6 services in an IPv4-only routed backbone network?

  A. NAT64 at the peering locations

  B. 6PE in the backbone network

  C. 6RD on CE routers and 6RD border relays at the peering locations

  D. dual-stack lite and NAT44 at the peering locations

  Correct Answer: C

• Question 295:

  A customer with a dedicated Frame Relay network plans to move its circuits onto a service provider converged MPLS network. Instead of moving to Ethernet access links right away, the customer wants to tunnel the Frame Relay information across the converged network. In which way is QoS information transmitted across an AToM pseudowire when tunneling Frame Relay traffic?

  A. QoS information cannot be transported through a pseudowire and is dropped.

  B. QoS information is preserved in the Frame Relay header and encapsulated into the pseudowire frame.

  C. QoS information is carried in a control word that is attached to the MPLS frame.

  D. QoS information is translated into ToS bits in the Ethernet header.

  Correct Answer: C

• Question 296:

  What is a characteristic of traffic shaping?

  A. It minimizes traffic transmission intervals.

  B. It remarks excess packets above the committed rates.

  C. It delays and can drop excess traffic.

  D. It classifies traffic based on certain characteristics.

  Correct Answer: C

• Question 297:

  Which two options are two characteristics of the single-tier headend architecture for DMVPN designs? (Choose two.)

  A. The mGRE and crypto functions are on the same router.

  B. Each DMVPN cloud has two different headend routers for high availability purposes.

  C. It is used in dual-cloud topologies for spoke-to-spoke connectivity.

  D. It only supports hub-and-spoke connectivity.

  E. Spokes cannot be used as RP in multicast deployments.

  Correct Answer: AC

• Question 298:

  In an MPLS-based network, there is a link that constantly flaps. This flapping makes the network constantly reconverge and causes it to become unstable. Which two technologies can be deployed to resolve the design failure? (Choose two.)

  A. IP Event Dampening

  B. BFD

  C. Carrier Delay

  D. IP Routing Protocol Route Purge

  Correct Answer: AC

• Question 299:

  Refer to the exhibit.

  

  Assume that no multicast optimization is done on LAN switches A and

  A. Which feature can be used to optimize multicast traffic forwarding in this situation?

  B. Enable IGMP snooping querier on both switches.

  C. Configure a static MAC entry for the multicast server.

  D. Disable IGMP snooping on both switches.

  E. Disable the IGMP query election process.

  F. Enable PIM Snooping on both switches.

  Correct Answer: A

• Question 300:

  A large retail bank is designing a unified communications solution to be deployed to its 200 branches. Its current network traffic consists of a web-based portal, Internet browsing, and general file server access. Each branch has between 15 and 20 users. The current WAN is based on Layer 3 MPLS and the customer manages its own CE routers. The WAN circuit interface to the service provider is Gigabit Ethernet, although the MPLS service that is contracted from the service provider is 10 Mb/s. The design is to use a DSCP-based four- class QoS policy to manage traffic demands. From the options below, which two QoS design options that should be implemented on the customer side will meet the requirement? (Choose two.)

  A. Shape traffic to 10 Mb/s on the CE router.

  B. Police traffic to drop outbound traffic that exceeds 10 Mb/s.

  C. Classify DSCP value EF for call signaling and voice packets, and place traffic in a strict priority queue.

  D. Priority queue traffic to demand up to 80% of total bandwidth.

  E. Enable DSCP-based WRED on all AF classes.

  Correct Answer: AE
