VMware 2V0-620 Online Questions & Answers

• Question 51:

  A company has decided to implement Virtual SAN within their vSphere 6.x environment. The Virtual SAN cluster will be composed of three ESXi 6.x hosts that are on the Virtual SAN Ready Node list.

  Each ESXi host includes: Two SAS Controllers that support Passthrough Mode Four Solid State Drives (SSDs) 1TB in size each 20 SAS Magnetic Disks (MDs) 1TB in size each The SSDs and MDs are evenly split between the two SAS controllers

  The company will pilot a Virtual SAN cluster utilizing VMware best practices while maximizing storage capacity. The Virtual SAN cluster will use Manual Mode.

  Which two Disk Group configurations would meet the stated configuration requirements? (Choose two.)

  A. 4 disk groups with 1 SSD and 5 MDs each
  B. 2 disk groups with 1 SSD and 7 MDs each
  C. 2 disk groups with 2 SSDs and 7 MDs each
  D. 2 disk groups with 1 SSD and 10 MDs each
  A. 4 disk groups with 1 SSD and 5 MDs each
  B. 2 disk groups with 1 SSD and 7 MDs each

• Question 53:

  Which two statements are true regarding VMware vSphere Flash Read Cache (vFRC)? (Choose two.)

  A. Cache fills and cache evictions happen in the granularity of a cache block size.
  B. vFRC caches data from both read and write I/Os, but write I/Os are always serviced by the underlying storage.
  C. vFRC caches data from both read and write I/Os, but write I/Os are always serviced by the underlying cache data.
  D. Cache fills and cache evictions happen in the granularity of the disk block size.
  A. Cache fills and cache evictions happen in the granularity of a cache block size.
  B. vFRC caches data from both read and write I/Os, but write I/Os are always serviced by the underlying storage.

  ---

  Cache fills and cache evictions happen in the granularity of a cache block size. This value ranges from 4KB to 1MB to enable you to best configure your cache block size based on the I/O size of workloads. Even though cache fills and cache evictions happen in the granularity of a cache block size, actual read I/O serviced by the cache can be smaller than the cache block size. For example, if the cache block size is 64KB, and a 4KB read I/O request is issued by the guest virtual machine, and if the data is not available in the cache, a 4KB read is issued to the VMDK. When populating the cache, the vFRC algorithm looks for a 64KB region to place the new 4KB data. If no free space is available, a 64KB region is evicted and the space is used to hold the new 4KB data. The remaining 60KB region in the 64KB cache block is marked as invalid. The cache block size parameter therefore has profound effects on performance

  D. Install and update third-party software on hosts.
  E. Upgrade virtual machine hardware.
  C. Upgrade and Patch ESXi hosts.

  vSphere Update Manager 6.x scan and remediation wizards offer upgrade and patch ESXi hosts, install and update third-party software and upgrade virtual machine hardware. Reference: http://www.vmware.com/pdf/vsp_vum_40_admin_guide.pdf

• Question 55:

  Which two are true about the Risk badge in vRealize Operations? (Choose two.)

  A. The Risk badge indicates potential future problems that may degrade the performance of the system.
  B. Risks may require attention in the near future.
  C. The Risk badge indicates problems that are degrading performance of the system.
  D. Risks require attention now to correct system performance problems.
  A. The Risk badge indicates potential future problems that may degrade the performance of the system.
  B. Risks may require attention in the near future.

  ---

  The Risk badge indicates potential problems that might eventually degrade the performance of the system. Risk does not necessarily imply a current problem. Risk indicates problems that might require your attention in the near future, but not immediately.

• Question 56:

  Which two actions allow for the disabling of Network Rollback operations? (Choose two.)

  A. Modifying the vpxd advanced configuration options and adding the config.vpxd.network.rollback key
  B. Modifying the C:\ProgramData\VMware\CIS\cfg\vmware-vpx\vpxd.cfg file and adjusting the xml tag

• Question 58:

  Refer to the Exhibit.

  

  An administrator is configuring an ESXi 6.x host to use multiple NICs to resolve a management network redundancy error. After configuring a second NIC, the server is not able to communicate when the primary connection is taken down. The administrator analyzes the Exhibit shown here.

  Based on the exhibit, what is the likely cause of the issue?

  A. vmnic4 is not attached to a vSwitch.
  B. vmnic2 is not connected to a physical switch.
  C. E1000 is the incorrect NIC Driver for this card.
  D. There is a MAC address conflict on the network.
  B. vmnic2 is not connected to a physical switch.

  ---

  The exhibit clearly shows that the vmnic2 is not connected to the physical switch that is why it is showing the down warning.

• Question 59:

  An administrator logs into the vSphere Web Client, but is unable to see any hosts and clusters. Which two options could fix the problem? (Choose two.)

  A. Verify that the client web browser and vCenter Server are in the same broadcast domain.
  B. Verify that the vCenter Server system is registered with the same Platform Services Controller as the vSphere Web Client.
  C. Log in to the vCenter Server as a user within the Active Directory domain.
  D. Log in to the vSphere Web Client as a user with permissions on the vCenter Server system.

• Question 60:

  An administrator is performing a scripted installation of ESXi 6.x.

  In which three locations does the script need to be? (Choose three.)

  A. PXE Server
  B. HTTPS
  C. FTP
  D. NFS
  E. VVOLs Datastore
  B. HTTPS
  C. FTP
  D. NFS

  ---

  Explanation:

  The script must be created using supported commands.

  Ensure you consider all disks that are connected to the host at the time of installation to avoid inadvertently overwriting data. Disk names can vary from machine to machine, one of the settings that you may want to configure and double check

  in a script is the disk selection for the ESXi installation.

  The host installation script must be stored in a location that the host can access by FTP. HTTP, HTTPS, NFS, USB flash drive, or CD-ROM drive. The installation media can be mounted on the host locally, remotely, or through PXE boot.
