The first thing the administrator should check is whether the server is in the collection that was scheduled to receive the update through SCCM. A collection is a group of resources, such as computers or users, that can be managed as a single entity by SCCM. If the server is not in the collection, it will not receive the update. The other options are less likely to be the cause of the problem, as they would affect other aspects of the server's functionality besides receiving updates. Reference: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.4: Given a scenario, apply patches/updates and validate their installation.

iSCSI is a protocol that allows SCSI commands to be transmitted over IP networks, enabling remote access to storage devices. iSCSI uses IP addresses to identify and communicate with the storage array, so having multiple IP addresses for the array indicates that iSCSI is being used. eSATA, USB, and FC are other types of connections that use different protocols and connectors than iSCSI. Reference: CompTIA Server+ Certification Exam Objectives, Domain 3.0: Storage, Objective 3.1: Given a scenario, install and deploy primary storage devices based on given specifications and interfaces.

After removing the virus from the server, the administrator should perform the following actions to mitigate the issue from reoccurring and to maintain high availability:

Run a vulnerability scanner on the server to identify any other potential weaknesses or exposures that could be exploited by attackers.

Patch the vulnerability that allowed the virus to infect the server in the first place, using the latest updates from the database software vendor or a trusted source.

Update the antivirus software on the server to ensure it has the most recent virus definitions and can detect and prevent future infections. The other options are either unnecessary or counterproductive for this scenario. Repartitioning the hard drive, reformatting the OS, removing the database software, or air gapping the server from the network would cause downtime and data loss, while enabling a host firewall would not prevent a virus infection from within the network. Reference: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.2: Given a scenario involving a security threat/vulnerability/risk, implement appropriate mitigation techniques.

The loud noises from the servers are most likely caused by failing hard disk drives, which can produce clicking or grinding sounds. Replacing the drives with new ones can prevent data loss and downtime.

Replacing the drives can be done without shutting down the server if they are hot-swappable, which means they can be removed and inserted while the server is running. Reference: CompTIA Server+ Certification Exam Objectives, Domain 3.0: Storage, Objective 3.1: Given a scenario, install, deploy, configure and update physical storage devices.

An access control vestibule is a physical security concept that limits personnel access to a restricted area within a data center. It is a small room or hallway that has two doors: one that leads to the outside and one that leads to the restricted area. The doors are controlled by an electronic lock that requires authentication, such as a card reader, biometric scanner, or keypad. Only authorized personnel can enter the vestibule and access the restricted area. Reference: CompTIA Server+ Certification Exam Objectives, Domain 5.0: Security, Objective 5.1: Given a scenario, apply physical security methods to a server.

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. Reference: CompTIA Server+ Certification Exam Objectives, Domain 2.0: Hardware, Objective 2.2: Given a scenario, install, configure and maintain server components.

A microSD card is the best method to stage the new media for the default boot device of a remote embedded IoT server that is having a Linux OS upgrade installed. A microSD card is a small and portable storage device that can store large amounts of data. It can be easily inserted into the slot of an embedded IoT server, which is a small and low-power device that performs specific tasks and connects to other devices over a network. A microSD card can also be formatted with different file systems, such as FAT32 or ext4, which are compatible with Linux OS. Reference: CompTIA Server+ Certification Exam Objectives, Domain 4.0: Networking, Objective 4.3: Given a scenario, configure servers for IoT applications.

Updating the firmware on the NIC is the most likely solution to fix the issue of a new 40GB NIC not being detected within the Windows server OS. Firmware is a software program that controls the functionality of a hardware device, such as a NIC (network interface card). A NIC is a device that enables network communication for a server by providing an interface between the server and the network cable or wireless connection. Updating the firmware on the NIC can improve its performance, compatibility, and stability with the server OS and network protocols. Reference: CompTIA Server+ Certification Exam Objectives, Domain 4.0: Networking, Objective 4.1: Given a scenario, configure network settings for servers.

The # symbol is used to write a text description per line within a PowerShell script. A text description is also known as a comment, which is a line of code that is ignored by the PowerShell interpreter and serves as documentation or explanation for human readers. The # symbol indicates that everything following it on the same line is a comment and not part of the script commands or expressions. For example:

This is a comment in PowerShell

Write-Host "Hello World" # This command prints Hello World to the console

Reference: CompTIA Server+ Certification Exam Objectives, Domain 6.0: Troubleshooting, Objective 6.3: Given a scenario, troubleshoot scripting errors using PowerShell commands.
