An administrator recognizes poor network performance when using CIFS shares from a PowerProtect DD system. The network link utilization is under 100%.
What is the most likely cause of this issue?
- A . TCP window size too small
- B . TCP timeout too small
- C . TCP timeout too large
- D . TCP window size too large
An IBM Spectrum Protect administrator would like to use the benefits of DD Boost.
Which technology will allow this integration?
- A . ICIFS
- B . NFS
- C . BooslFS
- D . VTL
C
Explanation:
BoostFS (Boost File System) is a DD Boost-enabled file system interface that allows applications like IBM Spectrum Protect to take advantage of DD Boost features, such as optimized deduplication, load balancing, and improved backup/restore performance. By using BoostFS, IBM Spectrum Protect can efficiently integrate with PowerProtect DD appliances to leverage DD Boost’s capabilities for faster and more efficient data transfer.
An administrator is configuring a Google Cloud Provider cloud unit on their DD9900.
Which certificate must be imported before adding the cloud unit?
- A . S3 Flexible
- B . Root CA
- C . GlobalSign Root R1
- D . GlobalSign Root R2
What is the primary role of the media server in Veritas NetBackup and Backup Exec environments?
- A . Monitoring backup data.
- B . Writes metadata to backup targets.
- C . Write to and read from backup targets.
- D . Creating backup policies.
Which method can be used to configure remote logging with syslog?
- A . The DD System Manager Maintenance > Logs page
- B . The REST API query in /nwrestapi/v3/global/alerts
- C . The log host command
- D . The log change command
Which product provides air-gap and minimizes the impact of a cyber-attack using a PowerProtect DD system?
- A . PowerProtect Cyber Recovery
- B . PowerProtect Data Manager
- C . NetBackup
- D . CyberSense
A
Explanation:
PowerProtect Cyber Recovery is designed to protect critical data from cyber threats by creating a secure, isolated environment (an air-gap) where backups can be stored. This air-gapped solution minimizes the impact of a cyber-attack by ensuring that critical data is inaccessible to attackers, even if they breach the main network. In the event of an attack, clean data from the secure vault can be used to restore the system to its pre-attack state.
A backup administrator is tasked with monitoring PowerProtect DD capacity metrics. The administrator is backing up 4 TB of data daily with a reduction rate at 5x. After data reduction, subsequent full backups compress down to 200 GB. The initial backup requires 800 GB with a 10 percent increase in the data each day.
Incremental backups are 400 GB. After data reduction, each incremental backup is 40 GB.
What is the weekly burn rate (GB) after four daily incremental backups and one weekly backup?
- A . 320
- B . 360
- C . 400
- D . 440
What is a requirement to use the PowerProtect DD HA feature?
- A . Each heed unit requires its own FS25 shelf.
- B . Head units and nodes require an active/active configuration.
- C . A single set of shared storage.
- D . Dual set of shared storage configuration.
D
Explanation:
For the PowerProtect DD HA feature to function effectively, a dual set of shared storage is necessary. This configuration provides redundancy and ensures that if one storage path fails, the other can maintain data availability. The dual shared storage setup enhances system resilience, allowing continuous operation and minimizing downtime in case of hardware failures or other issues.
Which Linux distributions support BoostFS?
- A . Raspbian, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server
- B . Debian, SUSE Linux Enterprise Server, and CentOS
- C . Red Hat Enterprise Linux, CentOS, and SUSE Linux Enterprise Server
- D . CentOS, Red Hat Enterprise Linux, and Debian
C
Explanation:
BoostFS is compatible with several Linux distributions, and the listed options include:
Red Hat Enterprise Linux (RHEL): A widely used enterprise Linux distribution known for its stability and support.
CentOS: A community-supported distribution derived from RHEL, providing similar functionality and compatibility.
SUSE Linux Enterprise Server: Another enterprise-level distribution that is known for its performance and support for various applications.
An administrator must display the compression statistics for all files and directories in the file system for the last 7 days and the last 24 hours.
Which command is used to gather this information?
- A . storage show
- B . mtree show
- C . filesys report
- D . quota show
C
Explanation:
The filesys report command provides detailed compression statistics, essential for administrators to monitor storage efficiency over time. This insight into compression ratios aids in storage optimization and management planning on PowerProtect DD systems.
