Question 3

Which of the following are true about WPA3? (Choose all that apply.)

Accepted Answer

WPA3 is the strongest wireless encryption standard, improving upon WPA2 by introducing new security features. It requires Protected Management Frames (PMF) to enhance protection against eavesdropping and other attacks. WPA3 is designed to be backward compatible with WPA2 devices, ensuring a smoother transition for existing networks. WPA3 does not use TKIP, which is an older encryption protocol associated with WPA, and it offers both Personal and Enterprise variations, not just the Enterprise version.

Question 6

Which of the following is a type of malware that isn't self-replicating and is usually installed by the user without his knowledge. It's primary goal is to invade your privacy by monitoring your system and reporting your activities to advertisers and spammers.

Accepted Answer

Spyware is not self-replicating and is often installed unknowingly by the user. Its main objective is to collect information about the user and send it back to advertisers or other third parties without the user's permission or knowledge.

Question 8

Which of the following is a type of denial-of-service attack that involves flooding the network with broadcast messages that contain a spoofed source address of an intended victim?

Accepted Answer

A smurf attack is a type of denial-of-service attack where a network is flooded with ICMP echo request packets, typically by using a botnet of compromised computers, and the packets have a spoofed source address of the victim's IP address. The hosts that receive the packets respond with echo replies, overwhelming the victim's network and causing denial-of-service. Packet storm and half-open SYN attacks also involve flooding a network, but do not specifically use broadcast messages with spoofed source addresses. A broadcast flood is a type of attack where the attacker sends a large number of broadcast packets to the network, causing congestion and potentially denying service to legitimate traffic.

Question 11

Which of the following is a credential category used in multifactor authentication? (Choose all that apply.)

Accepted Answer

In multifactor authentication, there are three categories of credentials that can be used: 
- Knowledge: Something the user knows, such as a password or PIN 
- Possession: Something the user has, such as a smartphone or an access card 
- Inherence: Something the user is, such as biometric data (e.g. fingerprint, face recognition)

Authority and rank are not categories of credentials used in multifactor authentication.

Question 16

You have been asked to determine what services are accessible on your network so you can close those that are not necessary. What tool should you use?

Accepted Answer

A port scanner is the best tool for determining which services are accessible on a network. It scans all ports on a system and identifies any open ports that may be running services. This information can then be used to identify which services are necessary and which ones can be closed to improve security.
