Huawei Certified Network Associate – Routing and Switching (HCNA-RS, legacy) — Question 69

Which of the following statements are true about the static MAC address table?

Answer options

• A. After a device is reset, an interface card is hot swapped, or an interface card is reset, the saved entries on the device or interface card are not lost.
• B. After an interface is statically bound to a MAC address, other interfaces discarded a packet whose source MAC address is the bound MAC address.
• C. Each static MAC address entry can be bound only to one outbound interface.
• D. You can check whether data is forwarded between two connected devices by checking the static MAC address entries.

Correct answer: A, B

Explanation

Option A is correct because static MAC address entries are retained even after device resets or interface card changes. Option B is also accurate as it describes how packets with a source MAC that matches a statically bound MAC are discarded by other interfaces. Options C and D are incorrect; option C is misleading as a single static MAC can be associated with multiple interfaces under certain conditions, and option D does not accurately reflect how MAC address entries work in this context.
