Huawei Certified ICT Associate – Data Center Network (HCIA-DCN) — Question 55

Which of the following packets are OSPF packets? (Choose all that apply.)

Answer options

• A. HELLO
• B. LSR
• C. LSU
• D. LSA

Correct answer: A, D

Explanation

The correct answers are A and D because HELLO packets are used to establish and maintain neighbor relationships in OSPF, while LSA (Link State Advertisement) packets are used to convey routing and topology information. Options B (LSR) and C (LSU) are not OSPF packets; LSR (Link State Request) and LSU (Link State Update) are related to OSPF but do not fall into the main packet types defined for OSPF communication.
