CISSP Question of the Week: Implement Redundant Servers

CISSP Question of the Week courtesy of Transcender Labs.

While completing the business impact analysis, the committee discovers that a human resources application relies on the following two servers:

• Human resources server managed by the human resources department in San Antonio, Texas
• Database server managed by the IT department in San Antonio, Texas

At the suggestion of the business continuity plan committee, management decides to implement redundant servers for both of these servers and place the redundant servers in the branch office in Seattle, Washington.

What are the two new servers an example of?

A. Preventative control
B. Reciprocal agreement
C. Interdependency
D. Backup strategy

Reveal Answer

The correct answer is A.

This is an example of a preventative control. During the business impact analysis, the business continuity committee will determine the threats to the organization. As part of this process, the committee will need to understand dependencies between the systems. Preventative controls may be suggested by the committee to prevent certain threats.

This is not an example of a reciprocal agreement. A reciprocal agreement occurs when two organizations agree to establish offsite facilities for each other. A disadvantage of reciprocal agreements is the site might not have the capacity to handle the operations required in a major emergency.

This is not a backup strategy. A backup strategy is formulated when you stipulate the time when actual backups occur and what types of backups occur. Backup strategies include backup tapes, electronic vaulting, remote journaling, and alternate facilities, including hot, warm, and cold sites.

This is not an example of interdependency. Interdependency occurs when two functions, departments, or processes rely on each other for functionality. While the relationship between the two servers is an interdependency, implementing redundant servers is a preventative control.
