Multifactor authentication strengthens account protection by requiring an additional authentication factor beyond a password. This is especially important for tenancy administrators because their privileges can affect resources and access throughout the tenancy. Oracle’s Security Policy for OCI Console includes an administrator rule requiring members of the Administrators group and users with administrator roles to enroll in MFA and provide an additional factor when signing in. Oracle recommends activating this protection and also supports MFA enforcement for other users. Giving everyone unrestricted policy-management access would undermine access control, while avoiding compartments does not improve administrator authentication. Using highly privileged accounts for routine work also creates unnecessary exposure. Among the listed choices, enforcing MFA is the documented security best practice.

Nano instances are not offered by OCI. The compute service provides other instance types like Virtual Machines, Bare Metal, and Dedicated Hosts but does not include Nano instances.

In OCI, the defining distinction is whether a subnet permits public IP address assignment to its resources. A public subnet permits public IP addresses, while a private subnet prohibits that assignment. Option B is therefore the best answer, but direct internet connectivity is not automatic merely because a subnet is public. An instance also needs a public IP address, an internet gateway, appropriate routing, and security rules that allow the traffic. Private-subnet instances can obtain outbound internet connectivity through a NAT gateway without receiving public IP addresses. Public and private subnets are not restricted to particular application roles, and public subnets do not universally require a /24 address range. Both belong within their VCN’s region.

This statement is NOT true. Compartments in Oracle Cloud Infrastructure do not provide a way to store and manage encryption keys and secrets. This functionality is typically handled by other services such as Key Management.

=================

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.
