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 choices
Show answer

Correct answer: 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.

Question 2 of 60

Which two tasks must be done to read data directly from IBM Softlayer Object Storage and insert it into a DB2 database? (Choose two.)

Answer choices
Show answer

Correct answers: A, C

To read data directly from IBM Softlayer Object Storage and insert it into a DB2 database, two tasks must be performed. 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 3 of 60

Which of the following statements about compression for BLU MPP tables is TRUE?

Answer choices
Show answer

Correct answer: D

Each table has a single compression dictionary that gets replicated across all partitions. This ensures that data consistency is maintained across partitions without requiring decompression when transferring data between partitions.

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 choices
Show answer

Correct answer: 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.

Question 5 of 60

Which statement about NOT ENFORCED unique constraints is TRUE?

Answer choices
Show answer

Correct answer: B

NOT ENFORCED unique constraints are informational constraints that help the query optimizer to select an optimal data access plan. Although they are not enforced, they provide valuable information to the optimizer about the uniqueness of the data, which can influence the selection of an optimal access plan.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
