A customer's multi-terabyte database environment is protected by a replicated Avamar Gen4S server and a Data Domain system at their headquarters (HQ) and disaster recovery sites. All backups are managed by Avamar with database backups directed to the integrated Data Domain system at each site.
The customer needs to add a 2 TB of database into the replicated environment. The disaster recovery Data Domain system is expandable but the HQ Data Domain system is full. They have asked for a recommendation for a replication solution.
Which solution supports the new capacity requirement for the least cost?
A. Add a Data Domain system to the Avamar/Data Domain system at the HQ site.
B. Add an Avamar server to both sites and integrate with the HQ Data Domain system.
C. No change in Data Domain capacity is needed at the HQ site.
D. Add a Data Domain system to the disaster recovery site.
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.
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 company's backup environment consists of both file system and database clients. An integrated Data Domain system was added to their existing EMC Avamar single-node Gen4S server to add backup capacity. Backups of several large Exchange and Oracle database clients were then reconfigured to back up to Data Domain storage. After several months, the backup administrator notices that the metadata utilization graph appears in red.
What is a possible cause?
A. Avamar cannot convert unused data stripes to metadata stripes.
B. Data Domain is unable to clean enough metadata containers to hold the backup data.
C. The Avamar server has exceeded 65% of GSAN utilization and backups have stopped running.
D. Avamar garbage collection has failed to free up the necessary empty stripes.
An EMC customer has an Avamar server integrated with a Data Domain appliance. Their administrator noticed in the Avamar Administrator GUI that the Data Domain status bar icon is showing the Data Domain system as unresponsive. What is the most likely impact of the problem?
A. Avamar cannot retrieve information from the Data Domain system. However, backups and restores can continue during this condition.
B. Avamar cannot connect to the Data Domain system, or the Data Domain system is disabled in some way. Backups and restores do not occur during this condition.
C. DD Boost cannot be used for backup operations.
D. Only recovery operations can be performed.
A database administrator is performing full backups of Oracle databases to an integrated EMC Avamar/Data Domain (DD) system. However, the backup administrator is concerned that the Data Domain back-end is running out of room. The administrator wants to start performing only incremental backups and store these backups on a second Data Domain system.
What advice should be provided to the administrator?
A. Perform one full backup from each client to the second DD system before sending incrementals to it.
B. Use the ddrmaint utility to send incremental backups to the second DD system.
C. Store all incremental backup data on the Avamar server instead of the second DD system.
D. Use DD Boost commands from the Avamar utility node to send the incremental backups directly to the second DD system.
A customer has an EMC Avamar server integrated with a Data Domain system as a backup solution. They would like to use encryption for the backups that are directed to the Data Domain system. What should you advise the customer?
A. Enable encryption-at-rest only on the Data Domain system.
B. Enable in-flight encryption between the client and the Data Domain.
C. Neither in-flight encryption nor encryption-at-rest are supported.
D. Both in-flight encryption and encryption-at-rest are supported.
A backup administrator with an existing Avamar 7.0 single-node server wants to integrate a Data Domain appliance running DDOS 5.2 into their backup environment.
To provide disaster recovery of the Avamar server the administrator wants to store Avamar checkpoint backups on the new Data Domain system. When configuring the checkpoint backup, an error is displayed.
What is the possible cause?
A. The Data Domain DDOS version needs to be 5.3 or above.
B. Avamar single-node servers do not support checkpoint backups to Data Domain.
C. Avamar 7.0 does not support checkpoint backups to Data Domain.
D. Data Domain does not support the storing of Avamar checkpoint backups.
A backup administrator with an existing Avamar 7.0 multi-node server has just integrated a Data Domain appliance running DDOS 5.3 into their backup environment.
To provide disaster recovery of the Avamar server, the administrator wants to store Avamar checkpoint backups on the new Data Domain system.
What would you advise the customer?
A. Avamar multi-node servers do not support checkpoint backups to Data Domain.
B. Avamar 7.0 does not support checkpoint backups to Data Domain.
C. The Data Domain DDOS version needs to be 5.4 or above.
D. Data Domain does not support the storage of Avamar checkpoint backups.
A customer's multi-terabyte database environment is protected by an EMC Avamar Gen4S server and an integrated Data Domain system at their central data center. The backup administrator reports that backups are failing and new backups will not start. Upon investigation, they discover that the Data Domain is full. How should this situation be resolved?
A. Manually delete the cur/DELETED directories on Data Domain and start cleaning.
B. Increase the frequency of Avamar garbage collection.
C. Manually delete several checkpoints and backups on the Avamar server.
D. Manually delete the cur/DELETED directories on Avamar and start garbage collection.
