Question 4 Single choice

A customer is successfully backing up 50 virtual machines (VMs) hosted on two ESX hosts. There are two datastores and two proxy servers used for VADP-based backups. They deploy another proxy server to backup 10 new VMs residing on a new datastore. The backups for the new VMs failed with the following error:

Event Code: 30931 - Failed to initiate a backup or restore of a virtual machine because no proxy was found to service the virtual machine.

What caused this error?

  1. A

    Not enough space is allocated on the proxy server to mount VM snaps

  2. B

    Proxy server is not provisioned on the new datastore

  3. C

    Proxy host has not been given backup privilege in the vCenter

  4. D

    New datastore is not selected for the proxy server in Avamar Administrator

Correct answer: D

Question 5 Single choice

A Dell EMC Avamar server performs nightly replication to an off-site Avamar server. The source server protects several small but important file system clients and several large database clients. The replication of the large databases often uses the entire replication window, preventing the small clients from replicating.

What can be done to ensure that the small clients and large DB clients replicate every day?

  1. A

    Separate the clients into groups based on size and schedule simultaneous replication

  2. B

    Throttle the network for the replication of the large clients

  3. C

    Reorder the clients in the replication group to place the small clients first

  4. D

    Replicate only the small clients on some days and all clients in one group on other days

Show answer and explanation

Correct answer: C

Question 6 Single choice

An EMC customer is looking for options to back up their smaller remote sites with easy remote management, so they want to use Avamar Virtual Edition (AVE). Before installing ESX hardware at the remote sites they want to do a proof of concept using the existing ESX 4.1 server that they have at the data center.

They provisioned 2 TB of virtual disks using VMAX thick provisioning with RAID 5 protection and zeroed out all blocks using eager zeroing. They tested the backup of three servers and do not see an improvement.

According to best practices, what should the customer have done to avoid performance issues?

  1. A

    Use RAID 10 for the virtual devices.

  2. B

    Use ESX 5.0i to host the AVE server.

  3. C

    Use thin devices for the virtual devices.

  4. D

    Use lazy zeroing to zero out all blocks.

Correct answer: A

Question 7 Single choice

A customer has a newly installed EMC Avamar. They have the following backup clients:

- Oracle database `Server DB1' with 1 TB of small databases, X86-64 architecture, 8 GB of RAM
- Oracle database `Server DB2' with 1 TB of small databases, SPARC architecture, 8 GB of RAM
- 60 file servers with 10 - 100 GB of data on each, X86-64 architecture, 4 GB of RAM

The backup window is four hours and overtime is not allowed. After kicking off the initial backups, an EMC Avamar backup administrator reports that Server DB1 completed its backup. However, Server DB2 did not.

Given the information provided, what is impacting the backup time and what can be done?

  1. A

    Server DB2 is SPARC. Hash calculations take longer than an X86; increase CPU power.

  2. B

    File servers are taking a long time to back up, delaying the other clients. Back up Server DB2 first and then back up Server DB1 and file servers.

  3. C

    Server DB1 is taking a long time to back up, delaying the other clients. Back up Server DB2 first, Server DB1 next, and then all file servers.

  4. D

    Server DB2 is SPARC. Increase the amount of RAM to hold more hash cache.

Question 9 Single choice

A Dell EMC Avamar backup administrator is running a Backend Capacity Report for several of their large backup clients.

What is a consideration when viewing the report?

    Some of the capacity shown may represent data used by other clients.

  3. C

    Both pre-deduplication and post-deduplication total GBs are displayed.

  4. D

    A report should be run separately for each client to get an accurate view of the total Avamar server capacity utilized.

  2. B

    For each backup client, create an LDAP map for each LDAP user that can administer the client.

  3. C

    For each backup client, create Avamar users with the same names and passwords as the LDAP users who can administer the client.

  4. D

    Create Avamar domains with the same names as the LDAP domains. Move specific backup clients to each Avamar domain.
