VMware 2VB-601 Online Questions & Answers

• Question 31:

  An eight-node vSAN cluster has been deployed. vSAN fault domains are NOT configured. A virtual machine with a 100GB virtual disk (VMDK) is created on the cluster. The 100GB virtual disk is assigned a storage policy with the following rules:

  1.

  Primary level of failures to tolerate = 1

  2.

  Failure tolerance method = RAID-1 (Mirroring) ?Performance

  Which statement is true about how vSAN places the component(s) that make up this object?

  A. Three mirrored data components are created and distributed across separate hosts. There is NO need for a witness component.
  B. Three mirrored data components plus a witness component are created. The data components are distributed across three hosts in the cluster. Witness components are placed on the hosts that contain data components to verify the data components are online.
  C. One data component is created to minimize capacity consumption. Two witness components are placed on separate hosts to avoid "split-brain" scenarios.
  D. Two mirrored data components plus a witness component are created. The components are distributed across three nodes in the cluster.
  B. Three mirrored data components plus a witness component are created. The data components are distributed across three hosts in the cluster. Witness components are placed on the hosts that contain data components to verify the data components are online.

• Question 32:

  With the Default vSAN Storage Policy applied to all virtual machines, which statement is true about a vSAN three-node configuration?

  A. RAID-5/6 erasure coding can be enabled to save space in an all-flash vSAN configuration.
  B. It can migrate all data from a node during maintenance.
  C. It requires a witness appliance.
  D. It can tolerate only one host failure.
  A. RAID-5/6 erasure coding can be enabled to save space in an all-flash vSAN configuration.

• Question 33:

  A 12-node vSAN cluster has been deployed across three server racks in a data center.

  1.

  There are four nodes in each server rack.

  2.

  A vSAN fault domain has been configured for each server rack for a total of three fault domains.

  3.

  All virtual machines in the cluster have the vSAN default storage policy assigned to them.

  4.

  This policy has not been modified.

  5.

  vSphere HA is enabled for the cluster.

  6.

  One of the server racks loses power.

  How does this affect virtual machines running on this cluster?

  A. Since there are four nodes in each server rack, erasure coding is used to rebuild data that was lost due to the server rack power failure. vSphere HA monitors the rebuild process and powers on all affected virtual machines after the rebuild process is complete.
  B. Virtual machine data in the failed server rack is rebuilt immediately using parity information. vSphere HA powers off and restarts all of the virtual machines to rebalance storage utilization across the cluster.
  C. All virtual machine data remains accessible. Virtual machines running on nodes in the failed server rack are restarted on nodes in the other two server racks. Virtual machines in the other two server racks continue to run.
  D. Virtual machines running on nodes in the failed server rack remain offline for 60 minutes. Virtual machines in the other two server racks continue to run and are marked "Degraded".
  C. All virtual machine data remains accessible. Virtual machines running on nodes in the failed server rack are restarted on nodes in the other two server racks. Virtual machines in the other two server racks continue to run.

• Question 34:

  Which two statements are true regarding storage policies? (Choose two.)

  A. Each VMDK within a VM may be assigned a different storage policy.
  B. Storage policies can be created that are not compatible with any datastores.
  C. Multiple storage policies can be assigned to a single VMDK.
  D. A maximum of four storage policies per datastore can be created.
  A. Each VMDK within a VM may be assigned a different storage policy.
  C. Multiple storage policies can be assigned to a single VMDK.

• Question 35:

  Which key is required to unencrypt an encrypted core dump when using vSAN encryption?

  A. Key Encryption Key (KEK)
  B. Disk Encryption Key (DEK)
  C. Host Key
  D. Internal Key in Digital Envelope
  C. Host Key

  ---

  The core dump is encrypted with the host key.

• Question 36:

  Which of the listed configurations is a valid and supported vSAN configuration?

  A. Four physical hosts Every host has one vSAN disk group Each vSAN disk group contains one cache device and five capacity devices The vSAN service is enabled on a VMkernel adapter on every host
  B. Three physical hosts Every host has one vSAN disk group Each vSAN disk group contains two cache devices and four capacity devices The vSAN service is enabled on a VMkernel adapter on every host
  C. Four physical hosts Two of the host have one vSAN disk group, the other two hosts are "compute-only" nodes Each vSAN disk group contains one cache device and three capacity devices The vSAN service is NOT enabled on the "compute-only" nodes
  D. Four physical hosts Two of the host have one vSAN disk group, the other two hosts are "compute-only" nodes Each vSAN disk group contains one cache device and three capacity devices The vSAN service is enabled on a VMkernel adapter on every host
  A. Four physical hosts Every host has one vSAN disk group Each vSAN disk group contains one cache device and five capacity devices The vSAN service is enabled on a VMkernel adapter on every host

• Question 37:

  Which two requirements must be satisfied for a v object protected by a RAID-1 mirroring policy to be accessible? (Choose two.)

  A. Primary level of failures to tolerate is set to 1 or higher.
  B. More than 50% of the object's votes must be available.
  C. Every component must have at least two votes.
  D. At least one full replica of the object must be available.
  E. vSphere HA must be enabled.
  B. More than 50% of the object's votes must be available.
  D. At least one full replica of the object must be available.

• Question 38:

  Which three statements are true regarding vsanSparse snapshots? (Choose three.)

  A. They require vSAN 6.0 or higher.
  B. They support up to 24 snapshots
  C. They use a copy-on-write format
  D. They use an always-sparse format.
  E. They are supported if a virtual machine has machine has existing vmfsSparse snapshots
  F. They are supported if the on-disk format is v1 or higher
  A. They require vSAN 6.0 or higher.
  D. They use an always-sparse format.
  E. They are supported if a virtual machine has machine has existing vmfsSparse snapshots

  ---

  AD (not C): vSAN 6.0 introduces a new on-disk format that includes VirstoFS technology. This always-sparse filesystem provides the basis for a new snapshot format, also introduced with vSAN 6.0, called vsanSparse.

  E: If the underlying is storage is vSAN, if the on-disk format is v2, and if there are no older vmfsSparse/redo log format snapshots on the virtual machine, vsanSparse format snapshots will be automatically used. If a virtual machine has existing vmfsSparse/redo log based snapshots, it will continue to get vmfsSparse/redo log based snapshots until the user consolidates and deletes all of the current snapshots.

  Incorrect Answers:

  B: A chain of up to 32 snapshots is supported.

  F: The new vsanSparse format leverages the underlying sparseness of the new VirstoFS filesystem (v2) on-disk format References:https://storagehub.vmware.com/export_to_pdf/vsansparse-tech-note

  C. Parity data is used to achieve higher performance.
  D. More raw storage device capacity is required than a RAID-5 configuration to achieve the same levels of availability.
