The storage type that will yield the fastest database read performance is SSD. SSD (Solid State Drive) is a type of storage device that uses flash memory to store data. SSDs have no moving parts and can access data faster than traditional hard disk drives (HDDs) that use spinning platters and magnetic heads. SSDs are especially suitable for databases that are mainly used for archival lookups, as they can provide faster response times and lower latency for read operations.

Before decommissioning and wiping a file server, it's crucial to verify the asset management documentation. This documentation provides detailed records of the server's lifecycle, including procurement, usage, maintenance, and decommissioning information. Ensuring that asset management documentation is up-to-date and accurate is essential before proceeding with the server's decommissioning to maintain proper inventory control, comply with regulatory and organizational policies, and facilitate any potential audits. While the media destruction method, recycling policy, and document retention policy are important considerations in the decommissioning process, verifying asset management documentation is the first step to ensure the server is correctly identified and accounted for in the organization's asset registry.

RAID 5offers bothdisk redundancyandmaximum usable disk capacityby using block-level striping with parity. RAID 5 allows one drive to fail while still retaining data, and it uses only one disk’s worth of space for parity, maximizing the usable capacity.

RAID 5 (Answer C):Provides redundancy with only one disk's space used for parity, maximizing storage.

RAID 0 (Option A):Provides no redundancy; if one drive fails, all data is lost.

RAID 1 (Option B):Mirrors data, so redundancy is provided, but only half the capacity is usable.

RAID 10 (Option D):Combines RAID 1 and 0 for high performance and redundancy but requires half the disk space for mirroring.

CompTIA Server+ Reference:This topic is covered underSK0-005 Objective 1.5: Explain RAID levels and their benefits.

Scenario: Migrating a stand-alone application storing PII to the cloud.

Data to Encrypt: Data at rest (Option B) should be encrypted:

Data in transit (Option A) and backups (Option C) are also important but not the primary concern here.

Data archives (Option D) may or may not contain sensitive data.

Comprehensive and Detailed Explanation:

Data Loss Prevention (DLP) policies are designed to detect and prevent unauthorized transmission of sensitive data outside the organization. Implementing DLP helps monitor and control data flows, ensuring proprietary information remains within the company.​

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:If the fans are running at full speed, it may indicate that the CPU or system temperature is too high. This is often caused by a poorly attached or improperly seated heat sink, which prevents efficient heat dissipation. Reattaching the heat sink with proper thermal paste resolves the issue.

A. Replace the PSU:Not relevant to temperature control.

B. Reseat the video card:Would not affect fan speed unless a GPU temperature issue exists, which is not stated here.

C. Reseat the RAM:Unrelated to fan operation.

Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:ABIOS passwordrestricts access to the motherboard's firmware settings and can prevent unauthorized users from altering critical system configurations, such as boot sequence or hardware settings.

Biometric lockis a physical security feature but does not restrict access to motherboard software directly.

Data-at-rest encryptionprotects data stored on the system's hard drives but does not secure the BIOS or firmware.

Bootloader authenticationensures that the operating system's boot process is secured, but it is not a method to restrict access to the motherboard's software.

If the network cable is functioning but there is no network connectivity, the next step would be to check theIPv4 options. This includes verifying that the server has a correct IP address, subnet mask, and gateway configuration.

IPv4 options (Answer B):Incorrect IP configuration is a common reason for network connectivity issues.

NIC firmware (Option A):Firmware issues are less likely if the NIC is detecting the cable and appears operational.

DHCP options (Option C):DHCP could be checked if automatic IP assignment is being used, but verifying IPv4 options manually is the first step.

Firewall options (Option D):Firewalls can block connectivity but should be checked after confirming IP settings.

DNS settings (Option E):DNS issues usually affect domain name resolution, not basic network connectivity.

CompTIA Server+ Reference:This topic is covered underSK0-005 Objective 3.1: Install and configure server components.

Aloopis a programming construct used to repeat a block of code multiple times. In this case, if a function needs to run ten times, a loop (such as afor looporwhile loop) would be the appropriate choice.

Loop (Answer A):This allows the function to be executed repeatedly without writing redundant code.

Variable (Option B):A variable is used to store data, but it doesn’t handle repetition.

Comparator (Option C):Comparators are used to compare values, not for repeating code.

Conditional (Option D):Conditionals (if, else) are used for decision-making, not repeating actions multiple times.

CompTIA Server+ Reference:This topic is related toSK0-005 Objective 1.1: Understand basic scripting and automation concepts.

Tailgating is a security breach where an unauthorized person follows an authorized individual into a secured area without proper credentials. To prevent tailgating, implementing an access control vestibule, also known as a mantrap, is highly effective.

An access control vestibule is a small room with two interlocking doors, where the first door must close and lock before the second door can be opened. This setup ensures that only one person can enter the secured area at a time, effectively preventing unauthorized individuals from gaining access by following someone else.

Other Options:

B. Cameras: While surveillance cameras can monitor and record entrances, they do not physically prevent tailgating. They serve as a deterrent and provide evidence after an incident has occurred but do not stop unauthorized entry in real-time.

C. Bollards: Bollards are physical barriers used to prevent vehicular access to certain areas. They are not effective in preventing unauthorized individuals from tailgating into a building or secured area.

D. Biometrics: Biometric systems (e.g., fingerprint or retina scanners) verify the identity of individuals but do not address the issue of someone following an authorized person through an open door. Without physical barriers like an access control vestibule, tailgating can still occur even with biometric systems in place.

Therefore, the most effective measure to prevent tailgating is the implementation of an access control vestibule.
