Designing Cisco Network Service Architectures (ARCH, legacy) — Question 16
An organization is using a link state routing protocol that is not dependent on IP addressing. Which action should be taken to enable routing across area boundaries in this environment?
Answer options
- A. Assign Level 1 router interfaces to different areas
- B. Assign Level 2 routers to different areas
- C. Assign Level 1 routers to different areas
- D. Assign Level 2 router interfaces to different areas
- E. Assign Level 2 router interfaceto the backbone area
- F. Assign Level 1 router interface to the backbone area AE
Correct answer:
Explanation
The correct answer is E, as Level 2 routers are required to connect different areas to the backbone area in link state protocols. Options A, B, C, and D do not fulfill the requirement of linking areas to the backbone, and F is incorrect as it discusses Level 1 routers instead of Level 2, which are essential for inter-area routing.
