 Application consistent backup is a method of backing up data that ensures the integrity and consistency of the application state. It involves notifying the application to flush its data from memory to disk and quiescing any write operations before taking a snapshot of the data. If the databases were not backed up to be application consistent, they might contain incomplete or corrupted data that cannot be restored properly.

Drives, fans, and power supplies are server components that can most commonly be replaced without downtime if they are hot-swappable. Hot-swappable components can be removed and inserted while the server is running, without affecting its operation or performance. Drives store data and applications, fans cool down the server components, and power supplies provide electricity to the server. Replacing these components can prevent data loss, overheating, or power failure. References: CompTIA Server+ Certification Exam Objectives, Domain 2.0: Hardware, Objective 2.2: Given a scenario, install, configure and maintain server components.

When a virtual server crashes and presents a Purple Screen of Death (PSOD), the immediate response should be to document the incident. Collecting a screenshot of the PSOD is crucial as it contains error codes and state information that can be used for diagnosing the root cause of the crash. Noting the details, especially those that come after the line detailing the OS version, can provide specific clues to what might have caused the server to crash. This is a standard best practice before rebooting the server, as it ensures that there is a record of the event to investigate and potentially prevent future occurrences. A hard reboot should only be done after this critical information has been recorded.

Using a network-based deployment, such as network booting (PXE - Preboot Execution Environment) or imaging through a server, is the most efficient way to load operating systems onto multiple machines simultaneously. This approach minimizes the manual intervention required for each device, as the administrator can initiate the operating system installation or imaging process across all desktops at once through the network. In contrast, using an SD card, DVD (Optical), or USB would require the administrator to physically move the media from one desktop to another, significantly increasing the setup time for each device.

A cold site is a backup facility with little or no hardware equipment installed. A cold site is the most cost-effective option among the three disaster recovery sites. However, due to the fact that a cold site doesn’t have any pre-installed equipment, it takes a lot of time to properly set it up so as to fully resume business operations1.

QSFP+ (Quad Small Form-Factor Pluggable Plus): This transceiver type is designed specifically to handle 40Gbps network speeds. QSFP+ connectors are hot-swappable and support various cable types, including fiber optic and copper (DAC).

10GigE: While a valid network technology, 10GigE only supports up to 10Gbps, not the required 40Gbps.

SFP (Small Form-factor Pluggable): A common transceiver type, but the standard SFP only supports a maximum of 1Gbps.

SFP+ (Enhanced Small Form-factor Pluggable): Supports up to 10Gbps, not sufficient for 40Gbps in this scenario.

A perpetual license is a one-time purchase that allows the software to be used indefinitely without recurring costs. This meets the requirement of a non-renewing, one-time capital expense.

Perpetual (Answer D): This is a one-time purchase and does not require renewal, making it ideal for capital expenditure.

Open-source (Option A): Open-source software is usually free but may not meet specific licensing requirements.

Subscription (Option B): This typically involves recurring payments, which contradicts the non-renewing expense requirement.

Volume (Option C): Volume licenses are used for purchasing multiple licenses at a discount but may still involve subscription-based renewals.

CompTIA Server+ Reference:This topic is covered under SK0-005 Objective 2.1: Explain licensing concepts for software.

The server has a CMOS battery failure and the time synchronization service is disabled on the servers. The CMOS battery is a small battery on the motherboard that powers the BIOS settings and keeps track of the date and time when the server is powered off. If the CMOS battery fails, the server will lose its configuration and display an incorrect date and time when it is powered on. This can cause access issues for users and applications that rely on accurate time stamps. The time synchronization service is a service that synchronizes the system clock with a reliable external time source, such as a network time protocol (NTP) server. If the time synchronization service is disabled on the servers, they will not be able to update their clocks automatically and may drift out of sync with each other and with the network. This can also cause access issues for users and applications that require consistent and accurate time across the network.
