Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 74

What is the characteristic of the TI-LFA?

Answer options

• A. It guarantees a loop-free path for all areas configured in OSPF
• B. It guarantees a loop-free path for all interfaces in the OSPF super backbone
• C. It applies only on the instance and makes all the interfaces inherit the configuration
• D. It applies on the area and instance and makes all the interfaces inherit the configuration

Correct answer: D

Explanation

The correct answer is D because TI-LFA is designed to enhance OSPF by ensuring loop-free paths at both the area and instance levels, effectively allowing all associated interfaces to inherit the configuration. Options A and B are incorrect as they limit the scope of TI-LFA to either areas or interfaces, while option C inaccurately suggests that it applies only to instances.
