VMware 2V0-622 Online Practice Questions and Exam Preparation

VMware 2V0-622 Online Questions & Answers

• Question 121:

  An administrator finds that the Microsoft Exchange virtual machines are exhibiting network latency. What two in-guest changes can help decrease latency? (Choose two.)

  A. PVDRMA
  B. TSO
  C. SR-IOV
  D. LRO
  B. TSO
  D. LRO

  ---

  Using TSO and LRO on physical and virtual machine NICs improves the performance of ESX/ESXi hosts by reducing the CPU overhead for TCP/IP network operations. The host uses more CPU cycles to run applications. If TSO is enabled on the transmission path, the NIC divides larger data chunks into TCP segments. If TSO is disabled, the CPU performs segmentation for TCP/IP. TSO is referred to as LSO (Large Segment Offload or Large Send Offload) in the latest VMXNET3 driver attributes. LRO reassembles incoming network packets into larger buffers and transfers the resulting larger but fewer packets to the network stack of the host or virtual machine. The CPU has to process fewer packets than when LRO is disabled, which reduces its utilization for networking.

• Question 122:

  Which component must be deployed before using encrypted virtual machines in a vSphere 6.5 environment?

  A. vCenter Server must use CA signed certificates
  B. a host with supported Trusted Platform Module
  C. supported password vault
  D. External Key Management Server
  D. External Key Management Server

• Question 123:

  A vSphere Administrator has received complaints that an MSCS cluster is failing over during vMotion operations. What action would minimize migrations for only the MSCS VMs?

  A. Configure the VM DRS Automation level to override as Partially Automated.
  B. Configure the migration threshold to Conservative for the vSphere DRS cluster.
  C. Configure the vSphere DRS cluster to be Partially Automated.
  D. Change the pathing policy to Round Robin for MSCS RDMS.
  A. Configure the VM DRS Automation level to override as Partially Automated.

• Question 124:

  Which three TCP/IP stacks are built in at the VMkernel level in vSphere 6 x? (Choose three.)

  A. Fault Tolerance
  B. vMotion
  C. Provisioning
  D. Management
  E. Default
  B. vMotion
  C. Provisioning
  E. Default

• Question 125:

  When enabling Storage DRS on a datastore cluster, which three components are enabled as a result? (Choose three.)

  A. Space load balancing among datastore within the datastore cluster.
  B. Initial placement for virtual disks based on space and I/O workload.
  C. I/O load balancing among datastores within the datastore cluster.
  D. Queue Depth alerting on disks within the datastore cluster.
  E. Data de-duplication within the datastore cluster.
  A. Space load balancing among datastore within the datastore cluster.
  B. Initial placement for virtual disks based on space and I/O workload.
  C. I/O load balancing among datastores within the datastore cluster.

  ---

  When you enable Storage DRS, you enable these functions:

  Space load balancing among datastores within a datastore cluster I/O load balancing among datastores within a datastore cluster Initial placement for virtual disks based on space and I/O workload

• Question 126:

  An administrator is attempting to access an ESXi host via the DCUI but is unable to do so. Which could be two possible causes? (Choose two.)

  A. The host in question has no out-of-band management capability (i.e. iLO/iDRAC).
  B. The SSH service is disabled on the host.
  C. Strict lockdown mode is enabled on the host.
  D. Normal lockdown mode is enabled and the administrator is a member of the Exception User list.
  E. The DCUI service is disabled on the host.
  C. Strict lockdown mode is enabled on the host.
  E. The DCUI service is disabled on the host.

• Question 127:

  A vSphere administrator observes a CPU spike on one of the web servers (view the Exhibit).

  

  Which two statements can describe the cause of this activity? (Choose two.)

  A. The network packet size is too large.
  B. Disk latency is present on the datastore.
  C. VMware Tools is not installed.
  D. The network packet size is too small.
  B. Disk latency is present on the datastore.
  D. The network packet size is too small.

  ---

  Network packet size is too small, which increases the demand for the CPU resources needed for processing each packet.
