physical server to another with zero downtime, continuous service availability, and complete transaction integrity.
QUESTION 59
What are two characteristics of VMware Consolidated Backup? (Choose Two.)
A.Image-level backups of virtual machines can be performed
B.A plugin integrates the VCB UI into VirtualCenter
C.LAN-free backups of virtual machines can be performed
D.File-level backups of Windows and Linux virtual machines can be performed
Answer: AC
Explanation:
VMware Consolidated Backup – Cost-Effectively Back Up Your Virtual Machines File level full and incremental backup. Recover individual files and directories (for virtual machines running Microsoft® Windows operating system).
Image level backup. Recover entire virtual machine image in the event of a disaster (for virtual machines running any operating system).
VMware vSphere VMware Consolidated Backup
Eliminate backup traffic with LAN-free virtual machine backup utilizing tape devices
QUESTION 60
What are three advantages of VCB over conventional agent-based methods of backing up a virtual machine’s (VM’s) data? (Choose three.)
A.allows selection of files and directories from the guest file system of a Linux VM
B.enables LAN-free backup and avoids undue overloading of the datacenter network
C.helps to eliminate the need for a backup window by using a “hot” snapshot-based backup
D.reduces the load on the ESX Server by moving backup tasks to a backup proxy machine
E.makes it possible to do both file-based and full-system backup of the same VM simultaneously
Answer: BCD
Explanation:
Eliminate backup traffic from your network to improve the performance of production virtual machines.
Eliminate backup traffic with LAN-free virtual machine backup utilizing tape devices.
Reduce the load on ESX Server and allow it to run more virtual machines.
VMware Consolidated Backup – Enable Non-Disruptive Backup for Virtual Machines
VMware Consolidated Backup takes a virtual machine snapshot and mounts the snapshot to the backup proxy server. As part of this process, the virtual machine is quiesced to ensure that the entire state of the virtual machine is captured at the point in time the snapshot is created
QUESTION 61
What is the advantage of installing backup client software in a Linux virtual machine’s guest OS?
A.This configuration enables individual files to be selected for backup or restore.
B.This configuration enables immediate booting from a restored virtual machine.
C.This configuration enables LAN-free backup.
D.This configuration enables ESX Server to do backup and restore operations.
Answer: A
QUESTION 62
You are trying to decide whether to back up virtual machines (VMs) using a backup agent in each guest OS or using a backup agent in the service console. When is it most appropriate to use the guest OS strategy rather than the service console strategy to back up VMs? (Choose two.)
A.when space for storing backups is severely limited
B.when quick recovery of full systems is a priority
C.when the current backup software license is per-server and is very costly
D.when all of the VMs must operate 24 hours a day, 7 days a week
Answer: AD
QUESTION 63
What are two advantages of VCB over conventional agent-based methods of backing up a virtual machine’s (VM’s) data? (Choose Two.)
A.enables LAN-free backup and avoids undue overloading of the datacenter network
B.makes it possible to do both file-based and full-system backup of the same VM simultaneously
C.helps to eliminate the need for a backup window by using an online, snapshot-based backup
D.allows selection of files and directories from the guest file system of any VM
Answer: AC
Explanation:
Eliminate backup traffic from your network to improve the performance of production virtual machines.
Eliminate backup traffic with LAN-free virtual machine backup utilizing tape devices.

QUESTION 64
What are two characteristics of VMware Consolidated Backup? (Choose two.)
A.It performs file level backups for Windows virtual machines.
B.It requires backup agents in virtual machines.
C.It allows the use of Fibre Channel tape from agents within the virtual machines.
D.It performs image level backups for Windows virtual machines.
Answer: AD
