    2. Private IP Address – Can only be reached from within the Amazon EC2 network (inside the same VPC or AWS region).

    A.be nested more than 3 levels

    B.be nested at all

    C.be nested more than 4 levels

    D.be nested more than 2 levels

    Answer:B

    be nested at all

    Explanation:

    In AWS Identity and Access Management (IAM), groups cannot be nested. This means:

    • An IAM group cannot contain another IAM group.
    • You can only assign IAM users to groups, not other groups.

    This design keeps IAM policies and permissions straightforward by avoiding complex inheritance structures.
