NEW QUESTION # 18
You have configured an Oracle Cloud Infrastructure (OCI) Load Balancer to distribute traffic to two compute instances in a private subnet. However, one of the target instance's health is marked as Critical. Which is NOT a typical reason for this?
- A. The target instance did not respond with a successful HTTP status code.
- B. The network security group rules of the target instance do not allow traffic on the necessary ports.
- C. The target instance is in a different availability domain than the Load Balancer.
Answer: C
Explanation:
The health of an instance in the context of OCI Load Balancer does not directly depend on its availability domain. Instances can be in different availability domains from the Load Balancer and still receive traffic as long as they are within the same region and the network configuration allows it. Typical reasons for an instance to be marked as Critical include failing health checks due to issues like improper security group configurations or the instance not responding correctly, but not because of its placement in a different availability domain.

NEW QUESTION # 25
Which statement best describes the default AuthZ behavior for users and groups in Oracle Cloud Infrastructure IAM?
- A. Users and groups must request access from the administrator for each resource.
- B. Access to resources in explicitly granted in policies; otherwise, it is denied by default.
- C. Users and groups arc granted access based on their roles without the need for policies.
- D. Users and groups are automatically granted access to all resources.
Answer: B
Explanation:
In Oracle Cloud Infrastructure (OCI) IAM, the principle of least privilege is applied, which means that access to resources is denied by default. Users and groups are granted access explicitly through policies that define the actions allowed on specific resources, ensuring that access is controlled and minimized to what is necessary.
NEW QUESTION # 26
