  A. gz

  B. lz

  C. lzw

  D. gzfast

  Correct Answer: D

  Explanation:

  The gzfast compression algorithm is the default local compression method used on all DD6900, DD9400, and DD9900 appliances.

• Question 33:

  Which protocol is used with Dell EMC Cloud Tier to transfer data between a PowerProtect DD appliance and the cloud?

  A. FTP

  B. SFTP

  C. HTTPS

  D. NFS

  Correct Answer: D

  Explanation:

  A DD series appliance at a Faction data center can be used as single backup target to protect workloads across multiple clouds. Using DD Boost, CIFS, and NFS protocols.

• Question 34:

  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.

• Question 35:

  How can remote logging with a syslog server be configured on a PowerProtect DD system?

  A. Use the CLI command log host enable

  B. Use the DDSM to enable the remote logging

  C. Remote logging is enabled by default

  D. Use the DDMC to enable the remote logging

  Correct Answer: A

• Question 36:

  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 37:

  What happens to the data when it is moved from the active tier to cloud tier?

  A. It is deduplicated and stored in a file system in the native format

  B. It is compressed and stored as object storage in a new format

  C. It is compressed and stored in block storage in a new format

  D. It is deduplicated and stored in object storage in the native format

  Correct Answer: A

  Explanation:

  Every file has a meta-data. Meta-data of the files which is getting moved is stored on active tier and data and metadata is moved into the cloud. There is no multiple data-movement policy set on single mtree. Data moved to particular cloud

  unit depends on datamovement policy. And only the unique data is sent to the cloud. This is done using the deduplication.

• Question 38:

  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 39:

  Which statement is correct regarding backup flow without PowerProtect DD?

  A. Data is replicated between primary storage and tape storage

  B. Both the backup server and backup clients connect directly to tapes and save the backup

  C. Only the backup server connects directly to tapes and saves the backup

  D. Only backup clients connect directly to tapes and save the backup

  Correct Answer: C

• Question 40:

  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
