2.4GHz Wi-Fi signals have better penetration through walls and other obstacles compared to 5GHz and
6GHz. Lower frequency waves (like 2.4GHz) travel farther and are less absorbed by physical barriers.
From the CompTIA A+ 220-1101 Official Study Guide, Objective 2.5 - Compare and contrast wireless networking protocols:
"The 2.4GHz frequency band offers greater range and better penetration through walls and obstacles than higher frequencies like 5GHz and 6GHz. Higher frequencies provide faster speeds but are more easily absorbed by walls." NFC (Near Field Communication) is not a Wi-Fi technology and works only over very short distances (a few centimeters).

High resource usage along with frequentpop-upsare strong signs of amalware infection. The next logical step is toupdate anti-malware definitionsandrun a full scanto detect and remove threats.
Option A:Network performance is likely not the root cause - local system behavior points to malware.
Option B:Drivers affect hardware functionality; they don't resolve malware-related slowness.
Option D:DHCP issues usually cause IP conflicts or no network access, not CPU spikes or pop-ups.
CompTIA A+ Core 1 Exam Objective Reference:
Objective 4.2: Given a scenario, detect, remove, and prevent malware using appropriate tools and methods.

Comprehensive and Detailed Explanation From Exact Extract:
SaaS (Software as a Service) is a cloud model that allows users to access applications over the Internet without managing the infrastructure or platform. Users can log in via a browser or app on any device, such as a laptop, with minimal configuration required.
Reference: CompTIA A+ Core 1 220-1201 Official Study Guide, Section: Virtualization and Cloud Computing ConceptsSaaS provides "ready-to-use" applications and is ideal for organizations looking to minimize local infrastructure needs.

An IDE hard drive uses a Molex connector for power. This 4-pin connector is a standard for older drives.
Why Not A (F type): F type connectors are used for coaxial cables in video and internet applications.
Why Not B (SC): SC connectors are for fiber optic cables.
Why Not D (Lightning): Lightning connectors are for Apple devices.

CompTIA A+ explains that Secure Boot is a UEFI security feature that prevents unauthorized or malicious bootloaders, rootkits, and unsigned OS loaders from starting during the boot process. Secure Boot verifies digital signatures on the OS and critical boot files before allowing startup, ensuring the system has not been tampered with.
TPM (Option A) provides encryption key storage and is used for BitLocker, but alone does not block malicious bootloaders. HSMs (Option B) are enterprise cryptographic devices, not PC boot protection features. BIOS passwords (Option D) restrict access to configuration but do not protect against malicious boot- level malware.
Windows 11 specifically requires Secure Boot, making it the correct protection mechanism for preventing startup-level malware.
Thus, Secure Boot is the proper choice.
