What are two valid address books? (Choose two.)
- A. 66.129.239.128/25
- B. 66.129.239.50/25
- C. 66.129.239.0/24
- D. 66.129.239.154/24
Answer: A,C
Explanation:
Network Prefixes in Address Books
You can specify addresses as network prefixes in the prefix/length format. For example, 203.0.113.0/24 is an acceptable address book address because it translates to a network prefix. However, 203.0.113.4/24 is not acceptable for an address book because it exceeds the subnet length of 24 bits. Everything beyond the subnet length must be entered as 0 (zero). In special scenarios, you can enter a hostname because it can use the full 32-bit address length.
