Designing Cisco Network Service Architectures (ARCH, legacy) — Question 33

An organization is acquiring another company and merging the two company networks. No subnets overlap, but the engineer must limit the networks advertised to the new organization.
Which feature implements this requirement?

Answer options

• A. Stub area
• B. Interface ACL
• C. Route filtering
• D. Passive interface

Correct answer: C

Explanation

Route filtering allows the engineer to control which routes are advertised to the new organization, effectively limiting the visibility of certain networks. Stub areas and passive interfaces serve different purposes, such as reducing route advertisements or preventing certain interfaces from sending updates, but they do not specifically address the requirement to limit advertised networks.
