AWS Certified SysOps Administrator – Associate (legacy) — Question 816

A route table in VPC can be associated with multiple subnets. However, a subnet can be associated with only ______ route table(s) at a time.

Answer options

• A. four
• B. two
• C. three
• D. one

Correct answer: D

Explanation

In an Amazon VPC, a subnet must be associated with exactly one route table at any given time to direct its network traffic. If no custom route table is explicitly associated with a subnet, it is automatically linked to the default main route table of the VPC. Thus, a subnet can never be mapped to multiple route tables simultaneously, making 'one' the correct limit.
