ITN 260 - Final Questions with Detailed
Verified Answers
Question: Which of these does not require authentication?
a. Open method
b. PSK
c. Enterprise method
d. Initialization method
Ans: a. Open method
Question: Which of these is a 24-bit value that changes each time a packet is
encrypted and then is combined with a shared secret key?
a. RC
b. IV
c. SL
d. SSD
, Page | 2
Ans: b. IV
IV stands for Initialization Vector.
The shared secret key is combined with an initialization vector (IV), which
is a 24-bit value that changes each time a packet is encrypted. The IV and
the key are combined and used as a seed for generating a random number
necessary in the encryption process. The IV and encrypted ciphertext are
both transmitted to the receiving device. Upon arrival, the receiving device
first separates the IV from the encrypted text and then combines the IV
with its own shared secret key to decrypt the data.
Question: Zariah is writing an email to an employee about a wireless attack
that is designed to capture the wireless transmissions from legitimate users.
Which type of attack is Zariah describing?
a- WEP-II
b- Bluetooth grabber
c- Rogue access point
d- Evil twin
, Page | 3
Ans: c- Evil twin
An evil twin is an AP set up by an attacker to mimic an authorized AP and
capture transmissions, so a user's device will unknowingly connect to the
evil twin instead of the authorized AP.
While a rogue AP is set up by an internal user, an evil twin is an AP that is
set up by an attacker.
A rogue access point is an illegitimate access point plugged into a network
to create a bypass from outside into the legitimate network. By contrast,
an evil twin is a copy of a legitimate access point.
A rogue AP is an unauthorized AP that allows an attacker to bypass many
network security configurations and opens the network and its users to
attacks.

Rogue APs do not even have to be separate network devices. The wireless
Hosted Network function in Microsoft Windows makes it possible to
virtualize the physical wireless network interface card (NIC) into multiple
virtual wireless NICs (Virtual Wi-Fi) that can be accessed by a software-
based wireless AP (SoftAP). This means any computer can easily be turned
into a rogue AP. Some smartphone apps also allow these devices to
function as APs.
Question: What is a difference between NFC and RFID?
a. NFC is based on wireless technology while RFID is not.
b. RFID is faster than NFC.
c. RFID is designed for paper-based tags while NFC is not.
d. NFC devices cannot pair as quickly as RFID
