• Question 103:

  Which two statements regarding to QoS marking are true? (Choose two)

  A. Shaping is one of the ways that packets can be remarked

  B. Class-based marking occurs after packet classification

  C. 802.1Q/p CoS bits and IP Precedence are both layer 3 marking fields

• Question 104:

  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.

  Correct Answer: D

• Question 105:

  Which two options are design considerations when introducing FCoE into an existing network? (Choose two)

  A. The FCoE QoS markings may overlap with call signaling QoS markings

  B. Optical cabling is needed to transmit FCoE traffic between a server and its directly connected Ethernet switch

  C. The existing network must support a MTU of 3280 bytes

  D. Twinaxial cabling can be used to transmit FCoE traffic between a server and its directly connected Ethernet switch, if it is less than 10 meters

  E. All the servers in the data center must be retrofitted with converged Network Adapters

  Correct Answer: AE

• Question 106:

• Question 107:

  What are two possible drawbacks of ending Loop-Free Alternate to support fast convergence for most destination IGP prefixes? (Choose two)

  A. The IGP topology might need to be adjust

  B. Loop-free alternate's convergence in less than 100 milliseconds is not possible

  C. Loop-free alternate's are supported only for prefixes that are considered external tot the IGP

  D. Loop-free alternates are not supported in global VPN VRF OSPF instances

  E. Additional path computations are needed

  Correct Answer: AE

• Question 108:

  B. UDLD can be enabled on REP interfaces to detect unidirectional failures.

  C. The guaranteed convergence recovery time is less than 50 ms for the local segment.

  D. A REP segment is limited to a maximum of seven devices.

  E. VLAN load balancing for optimal bandwidth usage is supported in any REP segment.

  Correct Answer: BE
