18
Q

A measure used in science and engineering that compares the level of a desired signal to the level of background noise.

A

Signal-to-Noise ratio

19
Q

What vulnerability does WPA2 possess?

A

It is weak against brute force offline attacks.

20
Q

What version of WPA uses TKIP and RC4?

A

WPA

21
Q

What version of WPA uses CCMP and AES?

A

WPA2

22
Q

What version of WPA uses QR codes for Easy Connect?

A

WPA3

23
Q

What is the purpose of the SSID?

A

To analyze wireless traffic, monitor network activity, identify security vulnerabilities, and troubleshoot networking issues.

24
Q

How does a federated connection work?

A

By connecting a device to multiple trusted networks in the same area.

25
Q

What are the 3 most common channels used on 2.4 GHz and why?

A

1, 6, 11. They are spaced out to prevent channel overlap.

26
Q

What is the relationship between Federation and RADIUS servers?

A

Both connect to trusted networks. RADIUS lets users connect to one network, while Federation lets users connect to multiple trusted networks.

27
Q

A model for establishing a large scale and diverse infrastructure for applications, and authenticate across multiple networks.

A

Federation

28
Q

Introduced MIMO, channel bonding, frame aggregation, up to 4 antennas. Has 2.4 or 5 GHz frequency.

A

WiFi 4

29
Q

Uses MU-MIMO, up to 8 antennas, beam forming. Has 5 GHz frequency.

A

WiFi 5

30
Q

Enchanced MU-MIMO, uses QAM (Quadrature Amplitude Modulation). Has 2.4 or 5 GHz frequency.

A

WiFi 6

31
Q

How many channels are on the 2.4 GHz frequency?

A

11

32
Q

A security protocol that encapsulates the Extensible Authentication Protocol within an encrypted and authenticated Transport Layer Security (TLS) tunnel.

A

PEAP

33
Q

Uses a pre-shared key called Protected Access Credential (PAC) to establish a TLS tunnel in which client credentials are verified.

A

EAP-FAST

34
Q

Uses TLS protocol to secure the authentication process.

A

EAP-TLS

35
Q

Having the server authenticate to the client with a certificate, but the protocol tunnels the client side of the authentication, allowing the use of legacy authentication protocols such as PAP, CHAP, and MS-CHAP. The authentication process is protected by the tunnel from man-in-the-middle attacks.

A

EAP-TTLS

36
Q

Family of digital modulation methods and a related family of analog modulation methods widely used in modern telecommunications to transmit information.

A

Quadrature amplitude modulation (QAM)

37
Q

A block cipher encryption protocol that’s symmetric. It uses the same key to both encrypt and decrypt data.

A

AES

38
Q

A data encapsulation encryption mechanism designed for wireless use.

A

CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol)

39
Q

An organization that promotes the development and application of electrotechnology and allied sciences for the benefit of humanity, the advancement of the profession, and the well-being of our members.

A

IEEE (Institute of Electrical and Electronics Engineers)

40
Q

Credentials that are distributed to clients for optimized network authentication. Can be used to establish an authentication tunnel between client and server.

A

PAC (Protected Access Credentials)

41
Q

A password based key exchange method developed for mesh networks.

A

SAE (Simultaneous Authentication of Equals)

42
Q

A unique identifier assigned to a WiFi network that allows devices on the network to identify and connect to the correct network.

A

SSID (Service Set Identifier)

43
Q

What points should you consider when determining WAP placement in a business environment?

A

Somewhere in the center of the area or in a place where the signal can reach all parts of the building equally.
