Question No: 81 – (Topic 2)

When you are configuring the NIC teaming policy for a vSwitch, what happens when the Failback to Yes?

  1. A failed uplink will be left inactive upon recovery until another uplink fails.

  2. The vswitch is notified when a failover event occurs.

  3. The physical switches are notified when a failback event occurs.

  4. A failed uplink is returned to active duty immediately upon recovery.

Answer: D

Explanation: 路 Select Yes or No to disable or enable failback.This option determines how a physical adapter is returned to active duty after recovering from a failure. If failback is set to Yes (default), the adapter is returned to active duty immediately upon recovery, displacing the standby adapter that took over its slot, if any. If failback is set to No, a failed adapter is left inactive even after recovery until another currently active adapter fails, requiring its replacement.

Question No: 82 – (Topic 2)

Which three features are only available in the vSphere Client when using a vSphere Distributed Switch? (Choose three.)

  1. Port Mirroring

  2. PVLAN tagging

  3. Storage I/O Control

  4. Ingress Traffic Shaping

Question No: 83 – (Topic 2)

What are three methods of adding virtual machine networking to a vSphere Distributed Switch? (Choose three.)

  1. A portgroup can be created using the vSphere client and virtual machines can be added using their Properties tab.

  2. A portgroup can be created as part of the Migrate Virtual Machine Networking wizard

    before virtual machines are moved to the vDS.

  3. A portgroup can be cloned from a vSphere Standard Switch, inheriting the virtual machines that were attached to the cloned portgroup.

  4. A portgroup can be created using the vSphere client and virtual machines can be migrated using the Migrate Virtual Machine Networking wizard.

  5. A portgroup can be created during the creation of the vDS and virtual machines can be migrated using the Migrate Virtual Machine Networking wizard.

Answer: A,D,E

Question No: 84 – (Topic 2)

What are two network load-balancing policies for a vSphere Distributed Switch? (Choose two.)

  1. Route based on source MAC hash

  2. Route using physical NIC load

  3. Route based on the destination virtual port ID

  4. Route based on port IP hash

Answer: A,B

Question No: 85 – (Topic 2)

  1. Isolated

  2. Promiscuous

  3. Community

  4. Trunked

Answer: C

Question No: 86 – (Topic 2)

Which methods can be used to migrate a VMkernel port from a vSphere Standard Switch to a vSphere Distributed Switch? (Choose two.)

  1. Use the Add Virtual Adapter wizard from the Manage Virtual Adapters window.

  2. Use the Manage Hosts wizard from the Configuration tab of the vDS.

  3. Use the Migrate Virtual Machine Networking option to select the port from a list.

  4. Edit the Network Adapter settings for the port and select a dvPort group from the list.

Answer: A,B

Question No: 87 – (Topic 2)

Which statement describes the functionality of traffic shaping on a vSphere Standard Switch?

  1. vSphere Standard Switches support only egress traffic shaping.

  2. vSphere Standard Switches support both ingress and egress traffic shaping.

  3. vSphere Standard Switches support best-effort traffic shaping based on quality of service (QoS).

  4. vSphere Standard Switches support only ingress traffic shaping.

Answer: A

Explanation: A traffic shaping policy is defined by average bandwidth, peak bandwidth, and burst size. You can establish a traffic shaping policy for each port group and each distributed port or distributed port group.

ESXi shapes outbound network traffic on standard switches and inbound and outbound traffic on distributed switches. Traffic shaping restricts the network bandwidth available on a port, but can also be configured to allow bursts of traffic to flow through at higher speeds.

Question No: 88 – (Topic 2)

Which vSwitch or vSwitch port group policy setting allows packets to be received by a virtual machine with different destination MAC addresses than the configured MAC address?

  1. Promiscuous mode

  2. Traffic shaping

  3. Forged transmits

  4. MAC address changes

Answer: D

Explanation: Mac address changes allows packets to be received by virtual machines with different destination mac addresses than the configured one.

Question No: 89 – (Topic 2)

What failure will beacon probing identify in vSphere networking?

  1. An improper VLAN configuration on a physical switch port

  2. A disconnected network cable

  3. A VMkernel IP mismatch affecting vMotion or HA traffic

  4. Jumbo frames improperly configured on an iSCSI target

Answer: A

Reference: http://kensvirtualreality.wordpress.com/2009/04/10/the-great-vswitch-debate- part-4/ (see beacon probing)

Question No: 90 – (Topic 2)

An administrator is creating a vSphere Standard Switch with virtual machine and VMkernel

networking. The administrator has two uplinks attached to the switch and wants to make sure multiple sessions for a virtual machine can utilize both uplinks.

Which load-balancing policy will guarantee this requirement is met, even if additional management or virtual machine traffic is added to the switch in the future?

  1. Route based on IP hash

  2. Route based on source MAC hash

  3. Route based on the originating port ID

  4. Use explicit failover.

Answer: A

Reference: http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf (page 8, see route based on IP hash)
