A. Performing database changes according to change management procedures

would be a normal function of the database administrator (DBA) and would be

compliant with the procedures of the organization.




B. Installing patches or upgrades to the operating system is a function that should

be performed by a systems administrator, not by a DBA. If a DBA were performing

this function, there would be a risk based on inappropriate segregation of duties.




C. A DBA is expected to support the business through helping design, create and

maintain databases and the interfaces to the databases.




D. The DBA often performs or supports database backup and recovery procedures.




The database administrator (DBA) suggests that database efficiency can be

improved by denormalizing some tables. This would result in:




Select an answer:

A.

loss of confidentiality.




B.

increased redundancy.




C.

unauthorized accesses.




D.

application malfunctions.

✓ :~~ You are correct, the answer is B.




A. Denormalization should not cause loss of confidentiality even though

confidential data may be involved. The database administrator (DBA) should ensure

that access controls to the databases remain effective.




B. Normalization is a design or optimization process for a relational database that

minimizes redundancy; therefore, denormalization would increase redundancy.

Redundancy, which is usually considered positive when it is a question of resource

availability, is negative in a database environment because it demands additional

and otherwise unnecessary data handling efforts. Denormalization is sometimes

advisable for functional reasons.




C. Denormalization pertains to the structure of the database, not the access

controls. It should not result in unauthorized access.

D. Denormalization may require some changes to the calls between databases and

applications, but should not cause application malfunctions.




The objective of concurrency control in a database system is to:




Select an answer:

A.

restrict updating of the database to authorized users.




B.

prevent integrity problems when two processes attempt to update the same data

at the same time.




C.

prevent inadvertent or unauthorized disclosure of data in the database.




D.

ensure the accuracy, completeness and consistency of data.

✓ :~~ You are correct, the answer is B.
