• Question 395:

  The network designer needs to consider the number of multicast applications and sources in the network to provide the most robust network possible. Which of the following is a consideration the designer must also address?

  A. The IGPs should utilize authentication to avoid being the most vulnerable component
  B. With SSM source or receiver attacks are not possible

  B. With SSM source or receiver attacks are not possible

• Question 396:

  A company is building a large data center. About 80% of its traffic will be north to south and the other 20% will be east to west. The company is also expecting a significant amount of data center growth over the next 5-10 years but wants to keep the cost of growth low. Which data center design is best suited to meet these goals?

  A. A spine and leaf design with layer 2/3 termination on the leaf nodes
  B. A two-tier design with the layer 2 termination on data center core
  C. A spine and leaf design with layer 2/3 termination on the spine nodes
  D. A three-tier design with a layer 3 termination on the data center core
  A. A spine and leaf design with layer 2/3 termination on the leaf nodes

• Question 397:

  Which option describes the effect of using softphones instead of VoIP handsets on QoS implementation for the voice traffic?

  A. It provides a Layer 2 CoS marking in the frames that can be used for QoS implementation.
  B. Using softphones means that 802.1Q tagging must be configured between the PC and the switch.
  C. The voice traffic of softphones is mixed with data traffic of PC on the access VLAN.
  D. By using softphones, the implementation of a QoS depends only on trusting DSCP markings set by the PC.
  C. The voice traffic of softphones is mixed with data traffic of PC on the access VLAN.

• Question 398:

  Which option is an advantage of using PIM sparse mode instead of PIM dense mode?

  A. No RP is required.
  B. There is reduced congestion in the network.
  C. IGMP is not required.
  D. It floods all multicast traffic throughout the network.
  B. There is reduced congestion in the network.

• Question 399:

  Which statement about data center access layer design modes is correct?

  A. The access layer is the first oversubscription point in a data center design.
  B. The data center access layer provides the physical-level connections to the server resources and only operates at Layer 3.
  C. When using a Layer 2 looped design, VLANs are not extended into the aggregation layer.
  D. When using a Layer 3 design, stateful services requiring Layer 2 connectivity are provisioned from the aggregation layer.
  A. The access layer is the first oversubscription point in a data center design.

• Question 400:

  Which two scaling factors are the most important to be considered for the Virtual Switching System model? (Choose two.)

  A. VSS stops VLAN spanning to the access switches.
  B. Both VSS nodes are active from control-plane perspective.
  C. STP must be implemented as a loop-avoidance mechanism.
  D. VSS eliminates the need to implement FHRP for each VLAN.
  E. STP root and FHRP primary must be tuned at the same node.
  A. VSS stops VLAN spanning to the access switches.
  D. VSS eliminates the need to implement FHRP for each VLAN.
