IBM Cloud Associate Developer — Question 3

A customer has defined a requirement to enable all virtual server instances in the proposed VPC to be able to access automatic operating system updates via the
Internet. What is required to provide this functionality?

Answer options

• A. The pre-defined Automatic Updates Security Group must be enabled
• B. Each server must have a Floating IP address
• C. Each subnet must have a Public Gateway
• D. A subscription to the IBM Auto Update proxy service

Correct answer: B

Explanation

To allow virtual servers to access the Internet for automatic OS updates, each server must have a Floating IP address, which provides the necessary public access. The other options do not directly enable the servers to reach the Internet, as Security Groups manage permissions, Public Gateways are for subnet access, and the IBM Auto Update proxy service is not required for basic Internet access.
