Designing Cisco Network Service Architectures (ARCH, legacy) — Question 47
Which two design concerns must be addressed when designing a multicast implementation? (Choose two.)
Answer options
- A. only the low-order 23 bits of the MAC address are used to map IP addresses
- B. only the low-order 24 bits of the MAC address are used to map IP addresses
- C. only the high-order 23 bits of the MAC address are used to map IP addresses
- D. only the low-order 23 bits of the IP address are used to map MAC addresses
- E. the 0x01004f MAC address prefix is used for mapping IP addresses to MAC addresses
- F. the 0x01005e MAC address prefix is used for mapping IP addresses to MAC addresses
Correct answer: A, F
Explanation
The correct answers are A and F. Option A indicates the use of the low-order 23 bits of the MAC address for mapping, which is accurate for multicast. Option F is also correct as it specifies the correct multicast MAC address prefix. The other options either provide incorrect bit mappings or incorrect prefixes for multicast addressing.
