Which is an important benefit provided by VLANs?

  • A. Reduced hardware requirements
  • B. Increased broadcast traffic
  • C. Fault tolerance
  • D. Increased security on a network segment


Answer : A

Explanation:
VLANs are virtual local area networks. They significantly reduce costs by saving money that can be spent on the purchase of switches, hubs and routers.

  • B. Virtual machines on any vSphere Standard Switch on the same ESXi host can receive the traffic.
  • C. Virtual machines in any port group on the virtual switch can monitor all of the traffic.
  • D. vMotion will not migrate any Virtual machines connected to a port group on the virtual switch.

An administrator is enabling Network I/O Control (NIOC) on a vSphere Distributed Switch.
Which types of network traffic can be prioritized with NIOC by default? (Choose three.)

  • A. FCP Traffic
  • B. NFS Traffic
  • C. Virtual Machine Traffic By Virtual Machine
  • D. iSCSI Traffic
  • E. vSphere Replication (VR) Traffic


Answer : B,D,E

When an explicit failover order has been configured on a virtual switch with multiple uplinks, what determines which uplink is used when a failover event occurs?

  • A. The first available uplink that reports a positive link state
  • B. The reported uptime for the surviving uplinks
  • C. The next available uplink on the list
  • D. The uplink with the shortest route


Answer : C

Explanation:
The next uplink is used logically when a failover event occurs. The next available uplink on the list will be the new uplink.

When PSA is coordinating the VMware NMP and any installed third-party MPPs, the MPPs perform which task?

  • A. Implement logical device bandwidth sharing
  • B. Handle I/O queueing to the logical devices
  • C. Provide logical device and physical path I/O statistics
  • D. Manage physical path claiming and unclaiming


Answer : D

When creating a dvPort group, which port binding option assigns a port to a virtual machine when the virtual machine is first powered on?

  • A. Static binding
  • B. Flexible
  • C. Ephemeral
  • D. Dynamic binding


Answer : D

In vSphere, a bound physical NIC can be configured to transmit and receive jumbo frames.
What is the default maximum transmission unit (MTU) in vSphere?

  • A. 1500
  • B. 5500
  • C. 9000
  • D. 9500

On which two vSphere elements can traffic shaping be configured? (Choose two.)

  • A. On a vSphere Distributed Switch dvPort for inbound and/or outbound traffic
  • B. On a vSphere Distributed Switch for inbound and/or outbound traffic
  • C. On a vSphere Standard Switch port group or the entire vSwitch for inbound traffic
  • D. On a vSphere Standard Switch port group or the entire vSwitch for inbound and outbound traffic


Answer : A,B

What would be a valid reason to enable traffic shaping?

  • A. Limiting the bandwidth of a FTP server
  • B. Restricting the load on a IDS server
  • C. Limiting the bandwidth used by an independent hardware iSCSI adapter
  • D. Improving the performance of a CPU-intensive application server


Answer : A

Explanation:
By limiting the bandwidth of a FTP server, you can enable traffic shaping.

A vSphere 5.x implementation contains two ESXi hosts, ESXi01and ESXi02. There is a virtual machine "VM21" connected to the Production port group on ESXi01.
ESXi01 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24

Production port group -

VMkernel port for vMotion -

VMKernel port for management -
vSwitch1, single uplink to 10.1.40.0/24

Engineering port group -

VMKernel port for NFS storage -
ESXi02 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24

Engineering port group -

VMkernel port for vMotion -

VMKernel port for management -
vSwitch1, single uplink to 10.1.40.0/24

Production port group -

VMKernel port for NFS storage -
Which two statements are true about this configuration? (Choose two.)

  • A. vMotion is not available between the two hosts
  • B. If VM21 is migrated to ESXi02 it will not be available on the network
  • C. The virtual machine can be vMotion migrated to the target host.
  • D. Broadcasts from the Production port group will not reach the Engineering port group.


Answer : B,D

Explanation:
If VM21 is migrated to ESXi 02, then according to the information provided, it will not be available on the network. Likewise, broadcasts from production port group will not reach engineering port group.

Which network settings are only available with vSphere Distributed Switches?

  • B. To share uplinks between vSwitches
  • C. When configuring iSCSI Software Initiator multipathing
  • D. If the physical switch does not support etherchannel or 802.3ad


Answer : C
