255.0.0.0

Answer 1

The subnet mask for a /22 prefix is 255.255.252.0.

Here's a brief explanation:

- A /22 means that the first 22 bits of the subnet mask are set to 1, and the remaining bits are set to 0.
- In binary, this would look like:
- 11111111.11111111.11111100.00000000
- Converting this binary representation to decimal gives you:
- 255.255.252.0

So the correct answer from your choices is **255.255.252.0**.
