  A. Network I/O Control

  B. CDP

  C. LLDP

  D. SR-IOV

  E. Port Mirroring

  Correct Answer: ACE

• Question 83:

  You have deployed a two-tiered application using four virtual machines:

  Two virtual machines are web application servers

  Two virtual machines providing a clustered database service

  What feature can you configure to provide the most accurate account for only the traffic between the web servers and the clustered database?

  A. On the vSphere Distributed Switch, configure the use of a port mirroring session using the Encapsulated Remote Mirroring (L3) Source session type.

  B. On the vSphere Distributed Switch, configure the use of a port mirroring session using the Remote Mirroring Destination session type.

  C. On the vSphere Distributed Switch, configure the use of an Isolated Private VLAN for the ports of the four virtual machines.

  D. On the vSphere Distributed Switch, configure Netflow for the distributed virtual port group and enable Process internal flows only for the distributed switch.

  Correct Answer: D

• Question 84:

  A network security administrator wants to monitor traffic on several VLANs configured on a vSphere Distributed Switch. The traffic will be sent to another distributed port.

  What type of port mirroring session must be configured to meet these requirements?

  A. Select the session type Distributed Port Mirroring when configuring the Port Mirroring session.

  B. Select the session type Remote Mirroring Source when configuring the Port Mirroring session.

  C. Select the session type Remote Mirroring Destination when configuring the Port Mirroring session.

  D. Select the session type Distributed Port Mirroring (legacy) when configuring the Port Mirroring session.

  Correct Answer: C

• Question 85:

  What are two valid methods of configuring virtual machines to use a vSphere Distributed Switch (vDS) that are currently using a vSphere Standard Switch (vSS)? (Choose two.)

  A. Select each virtual machine and drag it to the vSphere Distributed Switch.

  B. Select the vSS in use by the virtual machines and select the Move to option on the right-click menu.

  C. Select each virtual machine and edit the virtual network adapter's connection settings.

  D. Use the Migrate Virtual Machine Networking option from the right-click menu of the vDS.

  Correct Answer: CD

• Question 86:

  Which two characteristics of the underlying physical network does VMware NSX require for robust IP transport? (Choose two.)

  A. The physical network should provide scalable network I/O using Layer 2 Multipathing (L2MP) and Multichassis Link Aggregation (MLAG).

  B. The physical network should provide scalable network I/O using Equal Cost Multipathing (ECMP).

  C. QoS is not necessary since classification and marking will be done in the overlay.

  D. QoS classification and marking is required to provide end-to-end flow control.

  Correct Answer: BD

• Question 87:

  In a data center using a leaf and spine architecture, which two statements define the connectivity between the leaf and spine tiers required to provide optimal network connectivity for NSX? (Choose two.)

  A. Links are required between leaf and spine switches, and from each spine switch to other spine switches in the architecture.

  B. Links are required between leaf and spine switches in the architecture to form a point-to-point connection between the two tiers.

  C. High availalability and scalability should be achieved using NSX High Availability.

  D. High availability and scalability should be achieved using Equal Cost Multipathing (ECMP).

  Correct Answer: BD

• Question 88:

  On a vSphere Standard Switch, how does teaming two or more physical network adapters provide load balancing when using the Load Balancing feature Route based on the originating virtual port ID?

  A. They physical network adapter is chosen by use of a round robin based algorithm for each additional virtual port in the port group that becomes active.

  B. The physical network adapter is chosen by using the source IP address of the virtual machine and the destination IP address as variables in an algorithm.

  C. The physical network adapter is chosen by using the source MAC address as a variable in an algorithm.

  D. The physical network adapter is chosen based on the workloads from each port and the number of physical adapters.

  Correct Answer: A

• Question 89:

  If unicast mode is configured for the overlay transport in an NSX deployment, which two statements correctly define the network support that is required? (Choose two.)

  A. Configure NSX High Availability.

  B. Layer 2 switching support in the access and distribution layers

  C. Layer 3 switching support in the access and distribution layers

  D. Configure Jumbo Frame support

  Correct Answer: CD

• Question 90:

  Which statement best describes scaling a fault tolerant spine-leaf multipathing fabric architected for an NSX deployment?

  A. Scaling should be performed by replacing 1Gbps links in the architecture with 10Gbps links.

  B. Scaling should be performed by increasing the number of links from each leaf switch to the associated spine switches in the architecture.

  C. Scaling should be performed by increasing the number of spine switches while maintaining point-topoint connectivity between leafs and spines.

  D. Scaling should be performed by using layer 2 switching between the leaf and spine switches.

  Correct Answer: C
