Show Suggested Answer

Suggested Answer: C

The string of characters and digits that is entered into an AP and a client STA for WPA2 security and is 8 characters long is called apassphrase. A passphrase is a human-readable text that is used to generate a Pre-Shared Key (PSK) for WPA2-Personal security. A passphrase can be between 8 and 63 characters long and can include any ASCII character. The PSK is a 256-bit key that is derived from the passphrase using a hashing algorithm called PBKDF2. The PSK is used to encrypt and decrypt the data frames between the AP and the client STA. A MSK is a Master Session Key that is generated by an authentication server for WPA2-Enterprise security. A WEP key is a 40-bit or 104-bit key that is used for Wired Equivalent Privacy (WEP) security, which is deprecated and insecure. A PSK is not a string of characters and digits, but a binary key.Reference:[CWNP Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 303; [CWNA: Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 293.

Wait, is it really just 8 characters? That seems short!

I thought WEP keys were longer than that.

Definitely a passphrase, right?

I’m leaning towards PSK too, but I vaguely recall something about WEP keys being related to security as well.

I feel like the answer is definitely PSK, but I could confuse it with something else like an MSK.

I remember practicing a similar question, and I think a passphrase is usually longer than 8 characters, so that might not be it.

I think the string is called a PSK, but I'm not entirely sure if it specifically refers to the length.

I'm pretty sure the correct answer is Passphrase. That's the term used for the 8-character security string in WPA2 networks, right? I feel confident about this one.

Okay, I got this. The 8-character string is called a Passphrase, which is used for WPA2 security. The WEP key is a different thing, so that's not the right answer here.

I'm a bit confused on this one. Is the Passphrase the same as the WEP key? I need to double-check the differences between WPA2 and WEP security.

Hmm, this one seems straightforward. I think the answer is Passphrase, since it's an 8-character string of characters and digits used for WPA2 security.
