EMC Content Management Systems Architecture Sample Questions:

1. Click on the Exhibit button.

A customer has two possible non-High Availability physical configurations to choose from
(Architecture A or B shown in the exhibit).In Architecture A, the Symmetrix connections to the Content Server are via a high-speed Storage Area Network over Fiber interconnect. The Content Server machine exports a Network File System mount of the Index to the Index Server machine. In Architecture B, both the Content Server and the Index Server connect via Fiber to a CLARiiON SAN. The Symmetrix is configured with 100GB of RAM, while the CLARiiON only has 32GB of RAM. Which configuration would you recommend to the customer and why?

A) Architecture A: The larger disk cache of the Symmetrix will provide the best performance and eliminate query timeouts.
B) Architecture A: Only Symmetrix SAN's are recommended for the highly I/O intensive fulltext operations.
C) Architecture B: The lower cost of the CLARiiON will reduce Total Cost of Ownership (TCO).
D) Architecture B: NFS mounts of the full-text are not supported by the Index Server and lead to query timeouts.

2. After an upgrade from a pre 5.3 version to 5.3 or 6, what can you do to remove the Verity Full-text Index components?

A) The Content Server upgrade procedure deletes the Full-text. Just the empty/fulltext/Verity directory needs to be deleted in the DOCUMENTUM directory.
B) You delete the Documentum type dmi_tdk_index and the Full-text data in DOCUMENTUM/data directory.
C) You do not delete the Verity Full-text Index. The new Fast Full-text installation needs the data for migration.
D) You delete the Verity Full-text Index components via Documentum Administrator after the upgrade.

3. You have a Content Server installed on UNIX and users set up in a Windows NT domain.
How would you set up the authentication so that it requires minimal changes to the existing environment and is cost effective?

A) You edit the existing dm_check_password and customize it to authenticate the UNIX users on the Windows domain.
B) You migrate the NT domain users to an LDAP server and set up the repository to synchronize users with LDAP server.
C) There is no need to change anything. The default authentication would first attempt to authenticate the user on the UNIX operating system and then automatically fallback to the Windows domain.
D) You migrate the NT domain users to Active Directory and set up the repository to synchronize users with Active Directory.

4. Your client has a centralized repository with 100 million objects. Eighty percent of these are emails with an average size of 2k. The other 20% are office documents, with an average size of 100k. All of the content is stored on a NAS. However, for compliance purposes you client wants to transfer all email content to a Center A.
They have asked you to design a solution to efficiently perform the migration. Which solution meets the client's requirements?

A) put the repository in read-only mode so users can still access content; compress (zip) all of the content into a single file maintaining the exact file path and FTP it from the NAS device to the Centera; uncompress (unzip) the file on the Centera; create a new content addressable storage object in the repository that points to the Centera; update a_storage_type attribute of the email objects to point to the new CA store
B) create a new content addressable storage object; develop a multi-threaded routine that queries the repository for email objects and executes the migrate content method with the CA store as the target; incrementally migrate batches of content by executing this routine during off-peak hours
C) put the repository in read-only mode so users can still access content; copy all of the content via a multi-threaded FTP from the NAS device to the Centera, maintaining the exact file path; create a new content addressable storage object in the repository that points to the Centera; update a_storage_type attribute of the email objects to point to the new CA store
D) create a new content adressable storage object; using Content Storage Services (CSS), create a migrate content job; identify only the email objects to be migrated in the DQL of the job; specify the NAS as the source store and the Centera as the target store; schedule the job to run in a window each evening until all the content is migrated

5. Which statement is true about distributed objects?

A) Every mirror object has an associated Replica object.
B) A reference object only includes the original object's property data.
C) Replica objects always are of type dm_document.
D) A reference object is the internal link between the mirror object and the source object in the remote repository.
