The Domain Name System Security Extensions (DNSSEC) is a suite of Internet Engineering Task Force (IETF) specifications for securing certain kinds of information provided by DNS for use on IP networks.
DNSSEC is a set of extensions to DNS provide to DNS clients (resolvers) origin authentication of DNS data, authenticated denial of existence, and data integrity, but not availability or confidentiality. DNSSEC is necessary because the original DNS design did not include security but was designed to be a scalable distributed system. DNSSEC adds security while maintaining backward compatibility.

Launching Fileless Malware through Phishing Attackers commonly use social engineering techniques such as phishing to spread fileless malware to the target systems. Fileless malware exploits vulnerabilities in system tools to load and run malicious payloads on the victim's machine to compromise the sensitive information stored in the process memory. (P.978/962)

NOTE: In my opinion, this is an absolutely wrong statement of the question. But you may come across a question with a similar wording on the exam. What does "fast" mean? If we want to increase the speed and intensity of the scan we can select the mode using the -T flag (0/1/2/3/4/5). At high -T values, we will sacrifice stealth and gain speed, but we will not limit functionality.
nmap -T4 -F 10.10.0.0/24: This option is "correct" because of the -F flag.
-F (Fast (limited port) scan)
Specifies that you wish to scan fewer ports than the default. Normally Nmap scans the most common 1,000 ports for each scanned protocol. With -F, this is reduced to 100.
Technically, scanning will be faster, but just because we have reduced the number of ports by 10 times, we are just doing 10 times less work, not faster.

A Wireless Intrusion Prevention System (WIPS) is a network device that monitors the radio spectrum for the presence of unauthorized access points (intrusion detection), and can automatically take countermeasures (intrusion prevention).

In CEH v13 Module 11: Hacking Wireless Networks, WPA3-Personal is discussed as the latest wireless encryption standard designed to address the weaknesses of WPA2, particularly PSK brute-force vulnerabilities.
Key Features of WPA3-Personal:
Replaces the pre-shared key (PSK) with Simultaneous Authentication of Equals (SAE), also known as the Dragonfly Key Exchange.
SAE performs a zero-knowledge proof which makes it resistant to offline dictionary attacks.
Even if attackers capture the handshake, they cannot use it to brute-force passwords offline.
Option Clarification:
A). WPA3-Personal: Correct - uses SAE instead of PSK.
B). WPA2-Enterprise: Uses 802.1X, not related to SAE.
C). Bluetooth: Wireless protocol but unrelated to SAE or WPA.
D). ZigBee: IoT protocol; unrelated to Wi-Fi security protocols.
