VMware VMware Certifications VCP5-DCV Questions & Answers

• Question 491:

  Click the Exhibit button.

  

  An administrator has been tasked with adding a newly installed uplink to vSwitch1. Based on the exhibit, what is a true statement about this environment?

  A. The server does not have available vSwitches to be assigned to this uplink.

  B. The available uplinks are not compatible with a standard vSwitch.

  C. The host needs a driver installed for the newly installed uplink.

  D. The current uplinks cannot be attached because they are in use by other port groups.

  Correct Answer: C

  Explanation: as you can see that the Next button is greyed out. This means the host needs driver installed on the newly installed uplink. Once the driver in installed, the Next button will become active.

• Question 492:

  Which settings are required for virtual machine guest tagging for VLAN 100 in a vSphere 5.x environment?

  A. Port Group configured for VLAN 100, physical switch configured as a VLAN trunk

  B. Port Group configured for VLAN 4095, physical switch configured as a VLAN trunk

  C. Port Group configured for VLAN 100, physical switch configured for VLAN 100

  D. Port Group configured for VLAN 4095, physical switch configured for VLAN 100

  Correct Answer: B

  A VLAN ID, which restricts port group traffic to a logical Ethernet segment within the physical network, is optional. For a port group to reach port groups located on other VLANs, the VLAN ID must be set to 4095. If you use VLAN IDs, you must change the port group labels and VLAN IDs together so that the labels properly represent connectivity.

  If you enter 0 or leave the option blank, the port group can see only untagged (non-VLAN) traffic. If you enter 4095, the port group can see traffic on any VLAN while leaving the VLAN tags intact.

• Question 493:

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

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

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

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

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

  Correct Answer: D

  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 494:

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

  A. Port Mirroring

  B. PVLAN tagging

  C. Storage I/O Control

  D. Ingress Traffic Shaping

  E. 802.1q VLAN Tagging

  Correct Answer: ABD

• Question 495:

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

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

  B. A portgroup can be created as part of the Migrate Virtual Machine Networking wizard before virtual machines are moved to the vDS.

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

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

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

• Question 496:

  A virtual machine, VM21, will be migrated between two ESXi 5.x hosts, labeled ESXi01 and ESXi02. Each host has two vSphere Standard Switches (vSS), configured as follows:

  1.

  vSwitch0 has a portgroup labeled Management and a portgroup labeled vMotion.

  2.

  The Management portgroup contains a vmkernel port tagged for management traffic.

  3.

  The vMotion portgroup contains a vmkernel port tagged for vMotion traffic.

  4.

  vSwitch0 on ESXi01 has a single uplink attached to the 10.1.20.0/24 network.

  5.

  vSwitch0 on ESXi02 has a single uplink attached to the 10.1.20.0/24 network.

  6.

  Each host has a vSwitch1 with a Production portgroup used by virtual machine traffic.

  7.

  Each vSwitch1 has an uplink attached to the 10.1.40.0/24 network.

  What is true about migrating VM21 to the new host?

  A. vMotion would be supported in this configuration.

  B. Storage vMotion would not be supported in this configuration.

  C. vMotion would not be supported in this configuration.

  D. Storage vMotion would be supported if the storage device supports VAAI.

  Correct Answer: A

  As per the configuration shown in the question, vmotion will be supported without any problem.

• Question 497:

  A vSphere Standard Switch has been configured for IP-based load balancing using two uplinks. A new uplink is added to the vSwitch.

  What is the status of the uplink by default?

  A. The uplink is placed in standby mode until it is added to the active NIC team.

  B. The uplink is marked as active but does not participate in the active NIC team until assigned to a port group.

  C. The uplink is marked as active, but cannot be used by the active NIC team until it is added to the existing 802.3ad group on the physical switch.

  D. The uplink is marked as unused until it is added to the active NIC team.

  Correct Answer: C

  The new uplink will be marked as active but it cannot use active NIC team until it is added to an existing 802.3ad group on the physical switch. Reference: http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01990371/c01990371.pdf (page 26 onwards)

• Question 498:

  Which two statements are true regarding vSphere virtual switch uplinks? (Choose two.)

  A. vSphere virtual switches do not need to be configured with an uplink.

  B. Multiple vSphere virtual switches can be configured to use the same uplink.

  C. vSphere virtual switches must be configured with at least one uplink.

  D. Multiple vSphere virtual switches cannot be configured to use the same uplink.

  Correct Answer: AD

  VMware Virtual Networking Concepts, page 6. Some virtual switches should not connect to a physical network and thus have no uplink port. If you attempt to assign an uplink port, (previously assigned to a switch), to a second switch, the uplink will be disconnected from the first switch before being connected to the second.

  

• Question 499:

  Which two features secure the VMkernel? (Choose two.)

  A. Memory Encryption

  B. Hardware assist virtualization

  C. Kernel module integrity

  D. Trusted Platform Module (TPM)

  Correct Answer: CD

• Question 500:

  When would an administrator configure the Explicit Failover option for a portgroup created on a virtual switch with multiple uplinks?

  A. To manually configure load balancing for the portgroup

  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

  Correct Answer: C
