  A. Notification, Retention, Schedule
  B. Notification, Profile, Dataset
  C. Clients, Profile, Retention
  D. Dataset, Schedule, Retention

• Question 175:

  Garbage collection is running on an EMC Avamar server. Which activities can be performed at this time?

  A. Restore, browse existing backups, and queue backups
  B. Delete backups and change retention settings
  C. Change retention settings, and modify clients and domains
  D. Restore, delete backups, and add new clients
  A. Restore, browse existing backups, and queue backups

  ---

  This question was for Avamar 6 so removing queue from A will make it the best ideal answer. Situation in Avamar 7#

  

• Question 176:

  What is a characteristic of an EMC Avamar NDMP backup?

  A. After the first Level 0 backup, Level 1 backups are performed and merged to a full backup
  B. Every backup is a Level 0 backup
  C. Level 1 backups are performed daily and merged to a full backup at the end of the week
  D. Each backup is a Level 1 backup and is merged to a full backup only when a restore request is received
  A. After the first Level 0 backup, Level 1 backups are performed and merged to a full backup

• Question 177:

  At which percentage of user capacity are new backups suspended in an EMC Avamar environment?

  A. 85
  B. 95
  C. 96
  D. 100
  B. 95

  ---

  Capacity Threshold Warnings: 80% of user capacity = warning, start planning for expansion or cleanup 95% user capacity is the health check warning, new backups are suspended 100% user capacity makes the Avamar read-only, can still restore from server 85% of OS capacity = Garbage collection stops running, utilization increases rapidly 90% OS capacity = HFS checks stop running 96% OS capacity = no more checkpoints

• Question 178:

  What must be installed to perform Avamar file level recoveries of Exchange 2010 databases?

  A. Avamar Exchange Database and Exchange Message plug-ins
  B. Avamar Exchange VSS and Exchange GLR plug-ins
  C. Avamar Exchange Database plug-in and Exchange Recovery Storage Group
  D. Avamar Exchange VSS plug-in and Exchange Recovery Storage Group
  B. Avamar Exchange VSS and Exchange GLR plug-ins

• Question 179:

  Which client process listens for a work order from the EMC Avamar server?

  A. avagent
  B. avtar
  C. avscc
  D. mcs
  A. avagent

  Avamar Node Types and Processes There are several different types of Nodes within an Avamar Server. The Utility node is the identity of the Avamar Server and provides the bulk of the internal Avamar server processes such as: Avamar Administrator (used to manage the Avamar Server from a gui), cron jobs, DNS, NTP, external authentication, web access, MCS and EMS.

  MCS (Management Console Server) provides centralized management including scheduling of backups, restore of backups, monitoring and reporting.

  EMS (Enterprise Manager Server) provides web based management for multiple Avamar Servers as well as monitoring and configuration for Avamar Replication.

  Web Access provides access to documentation, backup plug-ins as well as remote File System restore access to end users.

  Are next type of node is the Storage Node, which run a process called gsan. This service communicates with the avtar command on the individual backup clients. Avtar communicates with a storage nodes gsan process, then that storage

  node spreads the data across the available data nodes.

  A Spare Node is an active node that is present in a multi-node RAIN (Redundant Array of Independent Nodes) grid. The interesting thing about the Spare Node is that it is NOT a hot spare. There is a procedure in place that needs to be

  followed when a failed Storage Node occurs. In fact, the Avamar Server doesn't even care if the Spare Node is powered on, so if you are a "Green" conscience company, feel free to leave the Spare Node powered down. EMC Best Practice is

  to leave the Spare Node up and active though. Avamar Backups clients can be installed with 2 different types of client plug-ins: File System and Databases. The Avamar client uses 2 processes in the backup and restore process: Avtar and

  Avagent. The Avagent process listens for backup/restore work orders from the MCS service on the Utility Node using port 28002 and executes the avtar command that handles the backup/restore processes and communicates with the gsan

  service on the storage nodes. This process is depicted in the included picture above.

  Lastly, in a previous blog, I discussed the 2 different licensable options for Avamar and how the disks are comprised in each Storage Nodes type. These are depicted in the picture above as well as a breakdown of how the disks are

  structured.

• Question 180:

  What is the purpose of running the EMC Avamar Virtual Edition benchmark process?

  A. Verify that the performance of the disk storage meets specifications
  B. Verify that there is enough memory
  C. Verify that there is enough storage available
  D. Verify that the CPU on the system is fast enough
  A. Verify that the performance of the disk storage meets specifications
