DevOps Tools Engineer (LPIC-OT 701) — Question 25

Which statements are true regarding databases during the deployment of a new release of a service using canary deployment? (Choose two correct answers.)

Answer options

• A. Changes to the database schema can take long and reduce the database performance.
• B. Traffic to the database will significantly increase because of the additional service instance.
• C. The database schema must be compatible to all running versions of a service.
• D. The database is locked while its content is copied to the canary database.
• E. Canary deployments require two synchronized instances of each database.

Correct answer: B, E

Explanation

Option B is correct because the introduction of an additional service instance increases the load on the database, resulting in higher traffic. Option E is also correct as canary deployments involve using two synchronized database instances to ensure data consistency. The other options do not accurately reflect the requirements or consequences of canary deployments.
