In the EMC Centera Console, there is a single domain named Default with one EMC Centera in the domain. The customer wants to rename this Default domain to "ABC."

How can this be done?

A. In the EMC Centera Console, highlight the Default domain name, right-click and select Rename from the menu

B. In the EMC Centera Console, under the edit menu, select Rename from the menu

C. The domain name cannot be renamed

D. Using the EMC Centera CLI, rename the domain Default ABC

An email archiving application writes the same 1 MB attachment 20 times to EMC Centera. The EMC Centera is set to storage strategy capacity, CPM, and running CentraStar 3.1.0.

After this ingest is finished, the customer claims SIS is not working because these ingests took more than 40 MB of metadata capacity on the cluster.

How can this be explained?

A. Detection and elimination of identical BLOBs is a background process and is not immediate

B. SIS has to be done by the application server when archiving emails

C. Storage strategy capacity needs CentraStar 3.1.3 to work correctly

D. Threshold is set incorrectly, thus all objects are stored with GM naming schemes

A customer's application uses the SDK to communicate to EMC Centera. A system environmental variable is recommended to point the application to the appropriate PEA file to use.

B. CENTERA_API_PEA

C. CENTERA_PEA_FILE

D. CENTERA_PEA_LOCATION

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.

Which process is responsible for block reclamation on the CUA?

A. Cache reclamation process

B. Invalidation job

C. Reclamation job

D. Writeback daemon process

Which privileges are needed to run EMC Centera Console Installer?

A. administrator

B. emcexpert

C. emcservice

D. root
