- C. A localized geographical area
- D. A type of encrypted traffic
Answer: B
Explanation:
An availability domain in Oracle Cloud Infrastructure refers to one or more data centers located within a region. Each availability domain is isolated from the others, with its own power, cooling, and networking to ensure fault tolerance and reliability.
NEW QUESTION # 25
What is the advantage of storing secrets in a vault in Oracle Cloud Infrastructure?
- A. It makes secrets easier to access in code.
- B. It automatically generates new secrets.
- C. It provides greater security than storing them in code or configuration files.
- D. It eliminates the need for authentication tokens.
Answer: C
Explanation:
Storing secrets in a vault provides greater security compared to storing them in code or configuration files. Vaults offer encryption, access controls, audit trails, and other security features to protect sensitive information from unauthorized access or exposure.
