EMC DES-DD33 Online Questions & Answers

• Question 1:

  A backup administrator needs to implement BoostFS for Windows.

  What do they need to install on the Windows server? (Choose all that apply.)

  A. CBFS
  B. CIFS
  C. NFS
  D. FUSE
  B. CIFS
  C. NFS

  ---

  Explanation:

  For CIFS/NFS/DD BoostFS, the first consideration to address is what level of CIFS, NFS and DD BoostFS sharing is wanted for the DD series appliances.

• Question 2:

  A backup administrator wants to verify that quotas have been enabled on a PowerProtect DD appliance. Which command is used to verify that quotas are being enforced?

  A. mtree show quota
  B. quota capacity status
  C. quota capacity reset
  D. quota capacity se
  D. quota capacity se

• Question 3:

  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
  A. Dell EMC Cloud Tier

  ---

  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 4:

  A backup administrator is tasked with verifying the compression savings of a PowerProtect DD9900. Which compression algorithm will they see enabled by default?

  A. gz
  B. lz
  C. lzw
  D. gzfast
  D. gzfast

  ---

  Explanation:

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

• Question 5:

  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
  D. NFS

  ---

  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 6:

  Which NDMP device is supported on a PowerProtect DD appliance?

  A. NFS
  B. DD Boost
  C. CIFS
  D. VTL
  D. VTL

  ---

  Explanation:

  A system can present itself as a file server, offering NFS, CIFS access over Ethernet; as a virtual tape library (VTL) over Fibre Channel; as an NDMP tape server over Ethernet; or as a disk target using application specific interfaces like DD

  Boost. DD VTL is qualified with leading open systems and IBMi enterprise backup applications.

• Question 7:

  What information does the daily Autosupport report contain?

  A. Quota alerts and MTree capacity
  B. System and Quota alerts
  C. System and MTree capacity
  D. MTree capacity and System alerts
  B. System and Quota alerts

  ---

  Explanation:

  The autosupport command manages system reports. Command options enable administrative users to manage two reports that describe the state of a Data Domain system: the autosupport report and the daily alert summary.

• Question 8:

  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
  B. Archived

• Question 9:

  How many hops should the fabric configuration be limited to when implementing the DD VTL?

  A. 1 hop
  B. 2 hops
  C. 3 hops
  D. 4 hops
  B. 2 hops

  ---

  Explanation:

  Maximum number of hops is two, that is, three DD systems. Directory-to-MTree migration supports backward compatibility up to two previous releases.

• Question 10:

  Backup administrators have noticed slow backups on the AIX environment.

  To fix the issue, what should the set large_send be for each NIC, and what should the NFS option be set to?

  A. no and nfs_rfc1323=0
  B. yes and nfs_rfc1323=0
  C. no and nfs_rfc1323=1
  D. yes and nfs_rfc1323=1
  D. yes and nfs_rfc1323=1

  ---

  larger RPC sizes, you should set the nfs_rfc1323 option Reference: https://www.ibm.com/docs/en/aix/7.2?topic=tuning-tcpip-guidelines-nfs-performance
