Cisco 352-001 Online Questions & Answers

• Question 521:

  You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers). The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS L3VPN, and L2VPN (pseudowire). Service

  Provider XYZ has these design requirements:

  - The network supports four service queues with equal treatment for delay, jitter, and packet loss.

  -Queues are numbered 0-3, where 0 is the default queue.

  -Three queues have one treatment.

  -

  One queue has either one or two treatments.

  If your design includes eight CoS queues on the Service Provider XYZ MPLS PE router ingress (CE facing)

  interface, how will customer traffic be classified as it enters the MLS P routers?

  A. The eight CoS queues in the MPLS P router are remapped to the eight CoS queues.
  B. Traffic is classified on the MPLS PE routers on core facing interface. The DSCP value is mapped into EXP field where multiple EXP settings (2+) will be assigned to a single queue throughout the MPLS P routers.
  C. Discard the traffic from the eight CoS queues that does not match the four CoS queues of the MPLS P routers.
  D. The 8 CoS queues in the MPLS P router are remapped to four 4 flow-label queues.
  B. Traffic is classified on the MPLS PE routers on core facing interface. The DSCP value is mapped into EXP field where multiple EXP settings (2+) will be assigned to a single queue throughout the MPLS P routers.

• Question 522:

  Which three techniques can be used to provide IPv6 first-hop security to prevent man-in- the-middle attacks? (Choose three.)

  A. DHCP snooping
  B. Dynamic ARP Inspection
  C. RA Guard
  D. ND Inspection
  E. BPDU guard
  F. IPv6 provider-independent address space
  A. DHCP snooping
  C. RA Guard
  D. ND Inspection

• Question 523:

  Refer to the exhibit.

  

  A new IPv4 multicast-based video-streaming service is being provisioned. During the design-validation tests, you realize that the link between the two buildings is carrying multicast traffic even when there are no receivers connected to the switch in Building B and despite IGMP snooping being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design change will prevent the multicast traffic from being unnecessarily flooded throughout the campus network?

  A. Enable PIM snooping on both Layer 2 switches.
  B. Enable multicast storm control on the link between Switch 1 and Switch 2.
  C. Use static Layer 2 MAC forwarding entries on Switch 1.
  D. Change the IPv4 multicast group address such that it excludes the usage of link-local MAC addresses.
  E. Ensure that Switch 1 is an IGMP querier.
  D. Change the IPv4 multicast group address such that it excludes the usage of link-local MAC addresses.

• Question 524:

  Which design option reduces the occurrence of IGP microloops?

  A. Deploy LSA throttle.
  B. Tune the SPF hold time to be lower than the SPF runtime on all nodes.
  C. Tune the SPF runtime to be lower than the SPF hold time on all nodes.
  D. Deploy LFA.
  D. Deploy LFA.

• Question 525:

  A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS traffic Engineering Fast Reroute solution has the same failover/ failback times as a traditional SONET/SDH network (around 50MSEC). In order to address both link failure and node failure within the lab typology network, which type of the MPLS TE tunnels must be considered for this demonstration?

  A. TE backup tunnel
  B. Next-hop (NHop) tunnel
  C. FRR Backup tunnel
  D. next-next-hop (NNHop) tunnel
  D. next-next-hop (NNHop) tunnel

• Question 526:

  Refer to the exhibit.

  

  This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or mechanism provides the shortest traffic outage if the link marked with "X" fails?

  A. PVRST
  B. REP
  C. MST
  D. G.8031
  E. BFD
  B. REP

• Question 527:

  In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability?

  A. Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers.
  B. Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers.
  C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.
  D. Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device.
  C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.

• Question 528:

  You are implementing a one-to-many multicast solution for a large service provider network. Which technology offers optimal routing of multicast traffic?

  A. Bidirectional PIM
  B. Anycast Rp
  C. MSDP
  D. PIM SSM
  E. PIM sparse mode
  D. PIM SSM

• Question 529:

  You are redesigning an OSPF v2 network and must migrate some links. You are concerned that there are different subnet masks. Which link type will still form an OSPF adjacency even if there are subnet mask mismatches?

  A. broadcast
  B. point-to-multipoint
  C. non-broadcast
  D. point-to-point
  D. point-to-point
