EMC Content Management Systems Architecture Sample Questions:
1. 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) 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
B) 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
C) 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
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
2. Your repository user accounts are created by linking users to their LDAP accounts. Today, your client asks you to allow an external group of users to the repository. How would you create these user accounts if they do not have a corresponding LDAP account?
A) create an LDIF file from the LDAP server and import it using Documentum Administrator
B) create the users in the repository with an Inline Password
C) create a text file in $DOCUMENTUM/dba/auth pointing to the new user's existing LDAP server
D) create a repeating attribute in dm_server_config that points to a second LDAP server; when you create the dm_user account, point to the new LDAP server
3. What is tiered storage?
A) a data storage environment consisting of two or more types of storage, differentiated by increased levels of support
B) a data storage environment consisting of two or more types of storage, manufactured by different vendors
C) a data storage environment featuring different storage platforms for top-tier, mid-tier, archive, and offline backup functions
D) a data storage environment consisting of two or more types of storage, differentiated by price, performance, capacity or function
4. Which statement is true about Recovery Time Objective (RTO) and Recovery Point Objective (RPO)?
A) RPO describes how current the data on the Disaster Recovery systems must be, while RTO defines the acceptable interval between system loss and restoration.
B) RPO defines the location(s) for Disaster Recovery, while RTO defines a specific time when systems will be restored.
C) RPO is typically more expensive to implement than RTO.
D) A client must choose between RPO and RTO strategies when implementing a Disaster Recovery (DR) plan.
5. On your current project, the system will serve users all over the world. While the application will essentially be the same for all users, multiple repositories will be deployed due to network constraints and content transfer volumes.Which technology enables deployment of consistent business rules to all users?
A) Federation Mediating Repository
B) Multiple Repository Distributed Configuration
C) Application Server Remote Deployment
D) Business Objects Framework Registry
