RAID 0 (striping) provides the fastest read (and write) speeds at the lowest cost, as all disk capacity is used for storage and performance. However, it offers no redundancy.
From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 - RAID types:
"RAID 0 stripes data across multiple disks, offering the best performance and lowest cost but no fault tolerance." Verified Source:

Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide) To run Secure Boot, the system must have:
# UEFI firmware (not legacy BIOS)
Secure Boot is a UEFI feature that validates bootloaders using digitally signed keys stored in secure firmware.
# TPM (Trusted Platform Module)
The TPM stores cryptographic keys in tamper-resistant hardware, enabling secure key management that cannot be altered by normal users.
CompTIA materials describe TPM as essential for enhanced platform security and for storing validated boot keys when Secure Boot is enabled.
Together, UEFI + TPM provide:
* Verified boot loader
* Hardware-level key protection
* Prevention of unauthorized OS tampering
* Non-user-controllable secure key storage
Why the other options are incorrect
A). VDI - Virtual desktops; unrelated to Secure Boot hardware requirements.
B). BIOS password - Helps protect firmware settings but is not required for Secure Boot.
E). Disabled boot drive - Irrelevant to Secure Boot.
F). USB permissions - Not part of Secure Boot requirements.

If the system reports"Bootable device not found", and the BIOS is configured correctly, the next step is torun diagnostics on the hard driveto check for physical or logical failure. It could be a sign of afailing drive or corrupt boot sector.
Option A:Reformatting the drive would erase data not a diagnostic step.
Option C:RAM does not affect whether a drive is bootable.
Option D:Replacing the drive should only be doneafter diagnostics confirm failure.

Objective 3.5: Given a scenario, troubleshoot problems related to storage devices.

AnMX (Mail Exchange)record defineswhich mail servers are responsible for receiving emailfor a domain. If you want to change or redirect email traffic, theMX recordmust be updated with the correct server information.
Option B (TXT):Stores text-based info - used for SPF, DKIM, etc.
Option C (SPF):Part of email authentication stored in a TXT record; doesn't redirect traffic.
Option D (CNAME):Alias for another domain name - not used for email routing.
