What is a significant limitation of MAC address filtering in network security?

It allows guest users to easily join the network.

It cannot accommodate a large number of MAC addresses. (correct)

It requires continuous updating of device addresses.

It relies on encryption for protecting data.

What does the initialization vector (IV) in WEP contribute to the encryption process?

The IV is combined with the WEP key to create a keystream. (correct)

The IV is a random vector that enhances key strength.

The IV prevents attempts to breach network security.

The IV can increase the length of the key.

How often do the IVs in WEP start to repeat, posing a security risk?

In less than 24 hours

In less than 7 hours (correct)

In less than 1 hour

In less than 48 hours
