Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 86

Which of the following statements are true about ACL deployment on Huawei devices? (Choose all that apply)

Answer options

• A. ACL can only be used in the outbound direction of an interface
• B. The same ACL can be used on multiple interfaces
• C. The ACL rules can only be configured in the following sequence: 10, 20, 30"¦
• D. ACLs cannot be used to filter OSPF traffic because OSPF does not use UDP to encapsulate packets
• E. ACLs can be used to match with the TCP/UDP port IDs of packets and to designate the port ID range

Correct answer: B, E

Explanation

Answer B is correct because the same ACL can indeed be applied to multiple interfaces on Huawei devices. Answer E is also correct as ACLs can match TCP/UDP port IDs and define a range. The other options are incorrect: A is wrong because ACLs can be used in both inbound and outbound directions; C is incorrect since ACL rules do not have to follow a strict sequence; D is false because ACLs can filter OSPF traffic despite OSPF using a different encapsulation method.
