EMC E20-895 Online Questions & Answers

• Question 141:

  An EMC customer operating 24/7 has a single node 7.0 Avamar server at their remote site to back up their file servers. They recently implemented Data Domain to back up their large file servers and database servers.

  They do not have DNS, and an iperf test shows they have 800 Mbps available bandwidth off their 1 Gbps LAN connection during backup hours.

  Based on EMC best practices, what should you advise the customer?

  A. Use the FQDN name of the Data Domain system.
  B. Use the CIFS protocol to write the file server backups.
  C. Upgrade the LAN bandwidth to 5 Gbps or higher.
  D. Use separate DD Boost user accounts for each file server.
  A. Use the FQDN name of the Data Domain system.

• Question 142:

  Which tape backup application is supported with ADMe?

  A. Avamar
  B. NetVault
  C. Veeam
  D. Backup Exec
  A. Avamar

• Question 143:

  A customer wants to restore a database to a certain point in time. The latest full backup and incremental backups are accessible and the original database is still online. What could be causing the point-in-time restore to fail?

  A. They tried to restore the database to another server.
  B. The database was online during the restore.
  C. They tried to restore to the same instance.
  D. The last full backup failed.
  A. They tried to restore the database to another server.

• Question 144:

  A customer has a large database server they would like to back up using an Avamar server integrated with a Data Domain system. The database server is an Intel x86-based machine with 16 GB of RAM. In addition, the server has 10 GbE connectivity to the Data Domain system and 1 GbE to the Avamar server. The customer asks how to size the cache files.

  What should be your response?

  A. Disregard the p_cache and f_cache files.
  B. Use the demand-paging cache strategy.
  C. Use 2 GB for f_cache and 1 GB for p_cache.
  D. Base the cache file sizes on the number of files in the dataset.
  A. Disregard the p_cache and f_cache files.

• Question 145:

  Refer to Scenario 9.

  

  How large can the hash file grow?

  A. 384
  B. 704
  C. 768
  D. 1000
  C. 768

• Question 146:

  A customer has four EMC Avamar servers located in a centralized disaster recovery site, each receiving replicated data from several remote sites. Several client backups are in the range of 1 - 4 TBs per dataset with file counts of 2 - 4 million files. Due to capacity limitations, Avamar retention value is limited to two months and tapeout is being used to provide extended retention of up to five years.

  The nature of the customer's business requires frequent lookups of historical data, often beyond the Avamar 2-month retention period. Therefore, quick recovery of files from tape is required. Compliance requirements mandate tapeout be performed on a weekly basis. The customer is considering Avamar Data Transport (ADT) or Avamar Tape Out (ATO).

  Which tapeout solution is best suited for this environment?

  A. ADT for its file level recovery capabilities from tape and its ability to process several TBs per day
  B. ATO due to its file level recovery capabilities from tape and its ability to process several TBs per day
  C. ADT due to its ability to write deduplicated data to tape and its ability to process several TBs per day
  D. ATO due to its ability to write deduplicated data to tape and its ability to process several TBs per day
  B. ATO due to its file level recovery capabilities from tape and its ability to process several TBs per day

• Question 147:

  A Dell EMC Avamar backup administrator is tuning the hash cache size to accommodate the backup of a 512 GB database. The database server has 8 GB RAM. To what value should the hashcachemax value be set?

  A. 768
  B. 1024
  C. 1408
  D. 1536
  A. 768

• Question 148:

  What is a characteristic of Avamar encryption?

  A. All data in the client-to-server and server-to-client authentication can be encrypted.
  B. All network data in both client-to-server and server-to-client authentication is always encrypted.
  C. A commercial certification authority must be used to allow for encryption of authentication data.
  D. Only the authentication requests from client to server can be encrypted.
  A. All data in the client-to-server and server-to-client authentication can be encrypted.

• Question 149:

  A customer is using deduplication nodes in their EMC NetWorker environment. They have configured a deduplication node to replicate to an alternate deduplication node and are cloning the metadata to a secondary device. After several successful backups, the customer wants to validate that they can recover data from the replication target.

  What can be done to ensure the data is recovered from the replication target?

  A. Set RECOVER_FROM_REP_HOST environment variable on the NetWorker server
  B. Set RECOVER_FROM_REP_HOST environment variable on the client system
  C. Initiate the recovery from the metadata clone volume
  D. Modify the client deduplication node setting to the replication target prior to running the recovery
  A. Set RECOVER_FROM_REP_HOST environment variable on the NetWorker server

• Question 150:

  Refer to the exhibit.

  

  The two SQL servers shown both have primary as well as secondary copies of databases. Which Avamar client can back up which SQL database?

  A. Each database copy can be backed-up by its local client.
  B. Each database copy can be backed-up by each client.
  C. Only the primary database copies can be backed-up by their local client.
  D. Only the secondary database copies can be backed-up by their local client.
  A. Each database copy can be backed-up by its local client.
