• Question 162:

  Which two actions are prerequisites to adding ESXi 6.x hosts to a vSphere Distributed Switch? (Choose two.)

  A. Verify that there is at least one Distributed Port Group on the Distributed Switch.

  B. Verify that the Distributed Port Group have active uplinks configured in its teaming and failover policy.

  C. Verify that the Distributed Switch has been configured with a Network Profile.

  D. Verify that Network I/O control for Management Traffic is configured for the highest share value.

  Correct Answer: AB

  To manage the networking of your vSphere environment by using a vSphere Distributed Switch, you must

  associate hosts with the switch. You connect the physical NICs, VMkernel adapters, and virtual machine

  network adapters of the hosts to the distributed switch.

  Prerequisites

  Verify that enough uplinks are available on the distributed switch to assign to the physical NICs that you

  want to connect to the switch.

  Verify that there is at least one distributed port group on the distributed switch.

  Verify that the distributed port group have active uplinks configured in its teaming and failover policy.

  A. Uplink Settings

  B. Switch Settings

  C. Portgroup Settings

  D. NIC Teaming Settings

  Correct Answer: B

  You can modify MTU values in switch settings.

• Question 164:

  An administrator is creating a new vSphere Distributed Switch that will be utilized with a specific vSphere Cluster. The cluster itself contains a mix of ESXi 5.x and 6.x Hosts.

  Which Distributed Switch version should be created to support this configuration?

  A. Distributed Switch: 6.0.0

  B. Distributed Switch: 5.0.0

  C. Distributed Switch: 5.1.0

  D. Distributed Switch: 5.5.0

  Correct Answer: B

• Question 165:

  An administrator is configuring the Failover Order option on a vSphere Distributed Switch.

  Which two options should be used with IP-hash load balancing? (Choose two.)

  A. Active Uplinks

  B. Standby Uplinks

  C. Unused Uplinks

  D. Override Failover Order

  Correct Answer: AC

  Active Uplinks, and Unused adapter Uplinks are used with IP hash load balancing.

• Question 166:

  How many Link Aggregation Groups (LAGs) can be configured on a vSphere 6.x Distributed Switch?

  A. 64

  B. 96

  C. 128

  D. 256

  Correct Answer: A

  You can create up to 64 LAGs on a distributed switch. A host can support up to 32 LAGs. However, the number of LAGs that you can actually use depends on the capabilities of the underlying physical environment and the topology of the virtual network. For example, if the physical switch supports up to four ports in an LACP port channel, you can connect up to four physical NICs per host to a LAG.

• Question 167:

  Which three connection types are available when configuring a vSwitch in the vSphere Web Client? (Choose three.)

  A. VMkernel Network Adapter

  B. Physical Network Adapter

  C. Virtual Machine Port Group for a Standard Switch

  D. vMotion Network Adapter

  E. vSAN Network Adapter

  Correct Answer: ABC

  Vmkernel network adapter, physical network adapter and virtual machine port group for standard switch are the connection types available when configuring Switch in vSphere client.

• Question 168:

  How are ports scaled on vSphere Standard Switches (vSS)?

  A. Ports on a vSS can be dynamically scaled up and down.

  B. Ports on a vSS can only be statically scaled up or down.

  C. Ports on a vSS can only be dynamically scaled down.

  D. Ports on a vSS can only be dynamically scaled up.

  Correct Answer: A

  To ensure efficient use of host resources on hosts running ESXi 5.5 and later, the number of ports of standard switches are dynamically scaled up and down. A standard switch on such a host can expand up to the maximum number of ports supported on the host.

• Question 169:

  What is the default load balancing policy for a newly created VMkernel port on a vSphere Distributed Switch?

  A. Route based on originating virtual port ID

  B. Route based on IP Hash

  C. Route based on source mac address

  D. Route based on physical NIC load

  Correct Answer: A

  The default load balancing policy is route based on originating virtual port ID.

• Question 170:

  An administrator is given a bash script that retrieves data for ESXi 6.x host configurations. This data needs to be collected right after the installation of a host and must be run directly on the host.

  Which two actions can be used to run this script on an ESXi host? (Choose two.)

  A. Connect to the host with Ruby vSphere Console and run the script from there.

  B. Enable SSH access from the Direct Console User Interface.

  C. Enable the ESXi Shell from the Direct Console User Interface.

  D. Run the script directly from the vSphere Web Client.

  Correct Answer: BC

  The Direct Console User Interface (DCUI) allows you to interact with the host locally using text-based menus. You can use the Direct Console User Interface to enable local and remote access to the ESXi Shell.
