Question 1 of 60
Assuming no database connections exist, which of the following will dynamically change the LOCKLIST database configuration parameter for a database named
SAMPLE to AUTOMATIC?
Answer

Suggested Answer

The suggested answer is D.

To dynamically change the LOCKLIST database configuration parameter for a database, you must ensure that the database is connected or the instance is attached. The correct command syntax for this operation is 'UPDATE DB CFG FOR sample USING LOCKLIST AUTOMATIC'. Since no database connections exist as per the question, attaching to the instance (db2inst1) and then updating the database configuration parameter would be the appropriate approach. Therefore, the best choice is to attach to the instance and then run the update command.

Answer

Suggested Answer

First, cataloging a storage access alias in the DB2 database is necessary to create an alias for accessing remote storage, which includes storing remote storage account credentials securely. Second, using the DB2REMOTE parameter of the LOAD command allows specifying a remote storage location, facilitating the direct access and manipulation of data stored on IBM Softlayer Object Storage.

Question 4 of 60
A production database has the following daily midnight backup schedule which includes all table spaces. The database incurs the same volume of daily activity
(inserts, updates, and deletes).

Sunday Delta -

Monday Incremental -

Tuesday Delta -

Wednesday Delta -

Thursday Incremental -

Friday Delta -

Saturday Full -
Which day would you expect a RECOVER DATABASE following that days backup to take the longest time to complete?
Answer

Suggested Answer

The suggested answer is A.

Recovering from a Delta backup requires restoring from the most recent full or incremental backup plus the delta backups since then. On Wednesday, recovery would involve restoring the Saturday full backup, the Monday incremental backup, and the delta backups from Tuesday and Wednesday. This makes Wednesday the day with the longest recovery time due to the cumulative restoration process from multiple preceding backups.

Answer

Suggested Answer

The suggested answer is B.

NOT ENFORCED unique constraints are informational constraints that help the query optimizer to select an optimal data access plan.
