JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2023) — Question 1

Which two statements are correct about IS-IS interface metrics? (Choose two.)

Answer options

• A. By default, an IS-IS interface has a maximum metric value of 1023.
• B. Wide metrics enable IS-IS interface to have a maximum metric value of around 16 million.
• C. Wide metrics enable an IS-IS interface to have a maximum metric value of 1023.
• D. By default, an IS-IS interface has a maximum metric value of 63.

Correct answer: B, D

Explanation

The correct answer is B and D. Option B is accurate because wide metrics do indeed allow for a maximum value of around 16 million, while option D is correct as the default maximum metric value for an IS-IS interface is 63. Options A and C are incorrect because A states the maximum metric value of 1023, which is not the default, and C incorrectly describes the maximum metric value for wide metrics.
