JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2025) — Question 92

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

Answer options

• A. IS-IS uses IPv6 as its transport protocol in the Junos OS implementation.
• B. IS-IS has two metric types and Junos sends both by default.
• C. IS-IS sends a maximum metric value of 63 by default.
• D. IS-IS only allows you to configure two areas.

Correct answer: B, C

Explanation

Option B is correct because IS-IS does utilize two different metric types, and Junos sends both by default. Option C is also accurate as IS-IS has a default maximum metric value of 63. Options A and D are incorrect; IS-IS does not use IPv6 as its transport protocol in Junos OS, and it allows for more than two areas to be configured.
