Q51.

What is a role in the context of data warehouse security?

A specific database operation

A grouping of users with common access requirements

An individual user's access privilege

A type of database connection

Discuss

Answer: (b).A grouping of users with common access requirements Explanation:In the context of data warehouse security, a role is a grouping of users with common access requirements.

Q52.

How are access privileges often granted in role-based security?

At the individual user level only

At the level of entire tables only

Exclusively through metadata security

At the level of a role

Discuss

Answer: (d).At the level of a role Explanation:Access privileges are often granted in role-based security at the level of a role.

Q53.

How are exceptions handled in role-based security when a user is part of a role?

All exceptions are automatically resolved at the role level.

Exceptions cannot be accommodated in role-based security.

Additional privileges are separately granted to the user to handle exceptions.

Users need to be removed from roles to handle exceptions.

Discuss

Answer: (c).Additional privileges are separately granted to the user to handle exceptions. Explanation:In role-based security, exceptions are handled by separately granting additional privileges to the user to handle specific exceptions.

Q54.

What is the main issue with passwords in a data warehouse environment?

They are required for data load jobs.

They are irrelevant to batch load jobs.

They are mainly used for deleting records.

They are not secure for data warehouse protection.

Discuss

Answer: (b).They are irrelevant to batch load jobs. Explanation:In a data warehouse environment, the main issue with passwords is to authorize users for read-only data access, as updates and deletes to the data warehouse records happen infrequently through batch load jobs.

Q55.

What additional security procedures are for passwords in a data warehouse environment?

Setting up acceptable patterns

Expiry period configuration

Changing passwords before expiry

All of the above

Discuss

Answer: (d).All of the above Explanation:Additional security procedures for passwords in a data warehouse environment include setting up acceptable patterns, configuring expiry periods, and changing passwords before expiry.

Q56.

What is the importance of following standards for password patterns in a data warehouse?

To make passwords easily recognizable

To allow users to apply their own exotic patterns

To ensure passwords are cryptic and arbitrary

To enable password sharing among users

Discuss

Answer: (c).To ensure passwords are cryptic and arbitrary Explanation:Following standards for password patterns in a data warehouse is important to ensure passwords are cryptic and arbitrary, not easily recognizable.

Q57.

What happens after a prescribed number of unauthorized attempts to gain access with invalid passwords in a data warehouse?

The user is automatically granted access.

The user is suspended until reinstated by the administrator.

The user's password is reset.

The user is permanently blocked from the data warehouse.

Discuss

Answer: (b).The user is suspended until reinstated by the administrator. Explanation:After a prescribed number of unauthorized attempts to gain access with invalid passwords in a data warehouse, the user is typically suspended until reinstated by the administrator.

Q58.

What is the primary security tool in the data warehouse environment?

Third-party security and management systems

Tool-based security within end-user tools

Database management system security

Overall security systems

Discuss

Answer: (c).Database management system security Explanation:In the data warehouse environment, the primary security tool is the security component of the database management system (DBMS).

Q59.

In the context of data warehousing, what is the primary reason for backing up the data warehouse?

To prevent unauthorized access

To recover from data loss in case of a disaster

To ensure data integrity during processing

To optimize query performance

Discuss

Answer: (b).To recover from data loss in case of a disaster Explanation:The primary reason for backing up the data warehouse in the context of data warehousing is to recover from data loss in case of a disaster.

Q60.

Why is the loss of data and downtime critical in OLTP mission-critical systems?

Loss of data can lead to legal consequences.

Downtime can cause financial losses and operational disruptions.

Downtime is necessary for routine maintenance.

Loss of data and downtime are not critical in OLTP systems.

Discuss

Answer: (b).Downtime can cause financial losses and operational disruptions. Explanation:In OLTP mission-critical systems, downtime can cause financial losses and operational disruptions, making the loss of data and downtime critical.
