Cisco Cisco Certifications 352-001 Questions & Answers

• Question 611:

  You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other. If the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you investigate to integrate into your network design? (Choose two.)

  A. EtherChannel

  B. MST

  C. Multichassis EtherChannel

  D. PVST+

  Correct Answer: AC

• Question 612:

  Refer to the exhibit.

  

  An enterprise is migrating its single-area OSPF network from a Frame Relay WAN service to an MPLS L3VPN service. Frame Relay will remain in only a few sites that require increased resiliency via two different WAN connections.

  Which feature could be used in the MPLS VPN service provider network to support the design requirement by ensuring that during normal operation, intersite traffic will only use the MPLS VPN service and not the old Frame Relay service?

  A. virtual links

  B. sham links

  C. multiple stub areas

  D. super backbone

  Correct Answer: B

• Question 613:

  What is the function of the Community String field defined in a trap PDU?

  A. enable the routing of messages

  B. allow authentication by management station

  C. enable reliable delivery of messages

  D. isolate the PDU within a defined region of the network

  Correct Answer: B

• Question 614:

  What is a key role for the access layer in a hierarchical network design?

  A. The access layer provides a security, QoS, and policy trust boundary.

  B. The access layer provides an aggregation point for services and applications.

  C. The access layer serves as a distribution point for services and applications.

  D. The access layer can be used to aggregate remote users.

  Correct Answer: A

• Question 615:

  Your company is designing a service provider network management solution in which customers are billed for 95th percentile network utilization. The service provider requires that an IETF standard be utilized to collect the data. Which method should be used to collect the data?

  A. IPFIX

  B. NETFLOW

  C. RMON

  D. IPFLOW

  E. NBAR

  Correct Answer: A

• Question 616:

  Refer to the exhibit.

  

  The design is being proposed for use within the network. The CE devices are OSPF graceful restart-capable, and the core devices are OSPF graceful restart-aware. The WAN advertisements received from BGP are redistributed into OSPF. A forwarding supervisor failure event takes place on CE A.

  During this event, how will the routes learned from the WAN be seen on the core devices?

  A. via CE A and CE B

  B. via CE A

  C. via CE B

  D. no WAN routes will be accessible

  Correct Answer: C

• Question 617:

  Which design concern should be accounted for in all Layer 3 virtualization technologies?

  A. Layer 3 redundancy

  B. packet sizing

  C. application usage

  D. Layer 3 stability

  Correct Answer: B

• Question 618:

  Which statement is true about connecting an IP multicast domain that is operating in PIM dense mode to a PIM sparse mode domain?

  A. The interconnection must be made at the rendezvous point of the PIM sparse mode domain.

  B. The connection can be made at any location in the network, as PIM sparse mode will inter-operate seamlessly with PIM dense mode.

  C. PIM dense mode and sparse mode domains are not inter-operable and cannot be connected.

  D. The connection can be made at any location in the network, but PIM sparse mode and PIM dense mode cannot inter-operate; IGMP must be used to provide the interconnection.

  Correct Answer: A

• Question 619:

  Which two practices should you implement to increase SNMPv1 security? (Choose two.)

  A. Restrict access to the specific SNMP engine IDs in use.

  B. Use ACLs to allow only specific IP addresses to poll SNMP.

  C. Use a combination of alphanumeric characters for the community strings.

  D. Use SNMP encryption for transport confidentiality.

  Correct Answer: BC

• Question 620:

  Refer to the exhibit.

  

  In this design, which technology would provide for the best use of resources to provide end-to-end Layer 2 connectivity?

  A. MSTP

  B. PAgP

  C. Multichassis EtherChannel

  D. LACP

  Correct Answer: C
