Which of the following is NOT a component typically involved in a DP4400 upgrade?
- A . Avamar Software
- B . Data Domain OS (DDOS)
- C . VMware ESXi
- D . Microsoft SQL Server
D
Explanation:
Microsoft SQL Server is not a native component of the DP4400 system. The key upgrade components include Avamar, DDOS, ESXi, and firmware.
Which of the following network ports is used exclusively for remote management on a DP4400?
- A . 10GbE Port 1
- B . 1GbE Port 1
- C . iDRAC Port
- D . 10GbE Port 3
C
Explanation:
The iDRAC port is used for remote management and is not part of data or backup traffic paths.
Which Data Domain command is used to display storage usage and deduplication savings?
- A . disk show state
- B . filesys clean start
- C . filesys show space
- D . system status
C
Explanation:
This command provides detailed information on disk usage, compression ratios, and deduplication savings.
What RAID level is configured by default on the DP4400 during installation?
- A . RAID 0
- B . RAID 5
- C . RAID 6
- D . RAID 10
C
Explanation:
RAID 6 is used by default on DP4400 to provide fault tolerance and allow up to two simultaneous disk failures.
After deploying DP4400 and running the first backup job, you are asked to verify deduplication efficiency.
What command can be used on the Data Domain system?
- A . dpnstat
- B . filesys show space
- C . system utilization
- D . ddboost view stats
B
Explanation:
This command shows space usage, compression, and deduplication savings on the Data Domain file system.
What should you verify regarding the storage system before starting an upgrade?
- A . That system time is synchronized
- B . That all nodes are powered off
- C . That sufficient free space is available
- D . That RAID controller is disabled
C
Explanation:
The system must have adequate free storage space on Avamar and Data Domain to perform upgrades safely.
Which command verifies that Avamar services are active following deployment?
- A . dpncheck
- B . status show all
- C . avagent list
- D . dpnctl status
D
Explanation:
This command checks the running status of all Avamar services, essential after initialization.
Which of the following enhances performance in large environments during deployment?
- A . Running backups during business hours
- B . Using DD Boost-over-FC when available
- C . Disabling deduplication
- D . Using 1GbE connections for all traffic
B
Explanation:
DD Boost-over-FC significantly increases throughput for backup operations by leveraging Fibre Channel speeds.
During monthly maintenance, the customer reports slow backup speeds. Reviewing Avamar logs reveals no issues. You check Data Domain and find replication is running concurrently.
What is the BEST optimization strategy?
- A . Disable all replication jobs permanently
- B . Throttle deduplication processes
- C . Reschedule replication to run outside backup windows
- D . Restart Avamar services to clear cache
C
Explanation:
Running replication during heavy backup periods can compete for I/O and network bandwidth. Rescheduling helps optimize performance without disabling essential features.
What is the purpose of the dpnctl status command in Avamar?
- A . To display detailed job logs
- B . To show the current status of Avamar system services
- C . To purge expired backups
- D . To configure SMTP alerts
B
Explanation:
dpnctl status verifies whether core Avamar services are active or stopped, a key health monitoring step.
