Question 8:
Which are supported compression algorithms in DDOS?
A. lz, gz, and gzfast
B. bmp, lz, and gz
C. rle, lzw, and lz
D. dsp, gz, and lz
Correct Answer: A
Explanation:
Prior generation appliances compressed data using the default lz algorithm. Other types of compression algorithms such as gzfast and gz were also available.

Question 9:
Which component executes the read/write requests in a backup environment consisting of a PowerProtect DD appliance and IBM Spectrum Protect?
A. Media Server
B. Media Agent
C. Spectrum Protect Server
D. Master Server
Correct Answer: B
Question 10:
When using the DD VTL Tape Out to Cloud feature, which status will a tape show once it is in the cloud tier vault?
A. Vaulted
B. Archived
C. Offline
D. Offsite
Correct Answer: B
Question 11:
What is a main advantage of using DD Boost instead of CIFS or NFS for a backup?
A. No requirement for an IP network to back up data
B. DD Boost does not require administration credentials
C. DD Boost uses integrated network acceleration
D. Deduplication is distributed between the backup server and client
Correct Answer: D
Explanation: Dell EMC Data Domain Boost software distributes parts of the deduplication process to the backup server(s) or application client(s), leaving the Data Domain system, powered by Intel® Xeon® processors, to focus its energy on determining what is unique and writing the new data to disk. With DD Boost, only the unique data has to travel from the backup server or client to the Data Domain system. DD Boost also gives the backup application control over replication

Question 12:
A backup administrator is tasked with monitoring PowerProtect DD capacity metrics. The administrator is backing up 2 ТВ of data daily with a reduction rate at 5x. After data reduction, subsequent full backups compress down to 100 GB.
The initial backup requires 400 GB with a 10 percent increase in the data each day. Each incremental backup is 200 GB. After data reduction, each incremental backup is 20 GB.
What is the weekly burn rate (GB) after six daily incremental backups and one weekly backup?
A. 200
B. 220
C. 400
D. 440
Correct Answer: A
Question 13:
What is the preferred method to ensure backups are protected against deletion or corruption?
A. Dell EMC Cloud Tier
B. Encryption
C. Retention Lock
D. Data Invulnerability Architecture
Correct Answer: A
Explanation:
In order to keep data protection tools from getting overwhelmed by the enormous capacity requirements generated in today\’s data centers, technologies which enable data to be tiered from primary backup to secondary long term retention/
archive are becoming more attractive. Dell EMC Cloud Tier technology integrates with an Dell EMC ECS Object Storage system (on premises or hosted private cloud) to provide a massively scalable architecture. By leveraging the capabilities
of both of these platforms, IT administrators and architects can continue the path of consolidating critical backup processes, protecting complex environments mixed with unstructured data, database engines, virtual environments, while at the
same time providing the ability to meet long term.
