Explanation

A read-only Oracle home separates the static software binaries from instance-specific configuration and log files, making the home directory itself immutable. Option A is correct because enabling it requires a software-only installation first (no DB created yet), followed by running roohctl -enable - only then do you create the database. Option E is correct because the immutable, self-contained nature of a read-only home means it functions as a "gold image" that can be cloned and distributed across many servers without modification, which is its primary operational value.

Why the distractors are wrong:

• B - Rapid Home Provisioning (RHP) is a separate Oracle fleet-management service; read-only homes do not require it, though the two features complement each other.
• C - This is the opposite of true. Config data and log files are stored outside the Oracle home (under ORACLE_BASE_HOME), which is precisely what keeps the home read-only.
• D - You cannot enable a read-only home during an installation that simultaneously creates a database; the software-only path is mandatory.

Memory tip: Think of a read-only Oracle home like a Docker image - immutable, shareable, and deployable everywhere, while each server keeps its own runtime config/logs in a separate volume. If config lived inside, it wouldn't be read-only.
