  Click the Exhibit button.

  A customer ordered two EMC Centera clusters and four CUAs. One EMC Centera and two CUAs (A and B) are installed in a production data center and EMC Centera (Y) and two CUAs (C and D) are installed in a DR data center. EMC Centera X and EMC Centera Y are replicating bidirectionally. The customer wants to configure the CUAs A and C in EA mode with CUA A, the active, configured with the access node IPs of EMC Centera x, and CUA C, the standby, configured with the access node IPs of EMC Centera Y.

  Similarly, the customer wants CUAs B and D in EA mode with CUA D, the active, configured with the access node IPs of EMC Centera Y, and CUA B, the standby, configured with the access node IPs of EMC Centera X. What is wrong with this configuration?

  

  A. Nothing. The configuration is a valid DR strategy.

  B. There may not be more than one CUA accessing a single EMC Centera Cluster.

  C. Two CUAs in an EA configuration must be located in the same data center so that the heartbeat Ethernet cable may be connected.

  D. Two CUAs in EA mode cannot be configured with the access node IPs of two different EMC Centera clusters.

  Correct Answer: D

• Question 34:

  When authorizing EMC Centera access, which search order does CUA 4.0 use?

  A. Access profiles for gateways or backup, Default access profile, PEA file, Anonymous profile

  B. Anonymous profile, Access profiles for gateways or backup, Default access profile, PEA file

  C. Default access profile, PEA file, Anonymous profile, Default access profile, Access profiles for gateways or backup

  D. PEA file, Default access profile, Anonymous profile, Access profiles for gateways or backup

  Correct Answer: A

• Question 35:

  After configuring replication, you run EMC Centera Verify to test replication. You wait a while, finally

  realizing that the test is taking longer than it should. You check the status of replication in the CLI, and see

  this message:

  Replication Paused: yes (insufficient capabilities).

  What is the most probable cause for this message?

  A. Replication profile does not have the proper granted rights to the pool being replicated

  B. Replication profile's PEA file is unreadable

  C. Wrong port number is added to the replication IP addresses that were entered when replication was enabled

  D. Wrong replication IP addresses were entered when replication was enabled

  Correct Answer: A

• Question 36:

  How does EMC Centera ensure content integrity?

  A. A universally unique hashing algorithm signature guarantees the storage of only a single instance of a BLOB object.

  B. EMC Centera sets retention on every object.

  C. EMC Centera uses shredded deletes to overwrite the location of deleted CDFs.

  D. Every time an object is read, EMC Centera calculates the Content Address of the object requested and compares the results.

  Correct Answer: D

• Question 37:

  You have installed the c2c utility and connected to the node running the command center. How is the smtp server configured?

  A. setconfig email_host

  B. setconfig mail_host

  C. setconfig smtp_host

  D. updateconfig smtp_host

  Correct Answer: C

• Question 38:

  An object is written to EMC Centera using an application profile. To which pool will the clip always belong?

  A. Cluster Pool

  B. ConsoleArchive Pool

  C. System Pool

  D. ONLY the homepool of the profile

  Correct Answer: A

• Question 39:

  What is the purpose of the CUA?

  A. Buffer large writes from applications to EMC Centera

  B. Encrypt application data written to the EMC Centera

  C. Provide EMC Centera access to applications that don't have the EMC Centera API built in

  D. Separate writes to the EMC Centera into component objects, such as CDFs and BLOBs

  Correct Answer: C

• Question 40:

  A customer is adding a DR EMC Centera to their environment. A migration is required to synchronize the two EMC Centeras. How does the C2C migration tool account for new writes to the production EMC Centera?

  A. It does not; new writes rely on replication

  B. It does not; the application must write to the new EMC Centera

  C. Migrates new data after it completes the legacy data

  D. Migrates new writes along with legacy data

  Correct Answer: A
