CompTIA Network+ (N10-007) — Question 326

A company's web-based application has a database that is set up for high availability in case of a failure. Which of the following is necessary to achieve this type of setup?

Answer options

• A. A virtual IP pointing to the active DB
• B. A static IP pointing to the passive DB
• C. A private IP pointing to the web front end
• D. A private IP pointing to the web proxy

Correct answer: A

Explanation

To achieve high availability for a database, a virtual IP that directs traffic to the active database is essential, as it allows for seamless failover without changing the IP address. The other options do not provide the necessary mechanism for maintaining continuous access to the database during a failure, as they either point to inactive resources or are unrelated to the database setup.
