JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 65

Which three benefits occur when operating an interior gateway protocol (IGP) in an autonomous system (AS)? (Choose three.)

Answer options

• A. IGPs learn prefixes in the global Internet’s routing table.
• B. IGPs react very fast to network change.
• C. IGPs automatically distribute static routing information.
• D. IGPs determine the optimal paths for data transmission.
• E. IGPs learn everything about the subnets and best paths within your network.

Correct answer: B, D, E

Explanation

The correct answers are B, D, and E because IGPs are designed to quickly adapt to network changes, determine the best routes for data transmission, and have comprehensive knowledge of subnets and optimal paths within the network. Option A is incorrect as IGPs do not learn prefixes from the global Internet’s routing table, and option C is incorrect because IGPs do not automatically distribute static routing information.
