HPE Aruba Certified Network Security Professional (ACNSP) — Question 15

What are two OSPF attributes within the hello messages that must match to successfully establish neighbor relationships? (Choose two.)

Answer options

• A. Router ID
• B. Priority
• C. Hello and Dead intervals
• D. Area ID
• E. Process ID

Correct answer: C, D

Explanation

For OSPF neighbors to form an adjacency, both the Hello and Dead intervals (C) and the Area ID (D) must match. Other attributes like Router ID (A), Priority (B), and Process ID (E) do not need to be the same for neighbor relationships to be established.
