The CompTIA 220-901 exam is one of two exams requires to obtain the CompTIA A+ (900 series). This exam will cover topics like networking, mobile devices and hardware and network troubleshooting.
PS/2 is an older port type that was predominately used for input devices like keyboards and mice. Lightning is a newer technology used primarily in Apple products. Firewire is not a likely answer, input devices for firewire is rare/nonexistent. Bluetooth is not likely to be supported on a server, especially an old server.

If your processor does not support virtualization you cannot run VMs on the server. Hyperthreading and multicore processors are nice-to-have but not essential. Dual voltage options are for power supplies, not processing.

Tone generator/probe will help you identify which cable runs to your office so you can see if it is connected. A loopback plug is for testing the NIC, which we already confirmed good. PING is an application/command used to test network connectivity, it won't help here. A cable tester would likely be the next tool used once we find our cable and confirm that it is connected.

The computer is likely a Linux/Unix (*nix) machine, ifconfig is the appropriate command to find the IP address in a *nix OS. Netstat will show active connections but not the IP address. Nslookup is for querying DNS. Tracert is not likely to work on a *nix box, nor will it display for IP since it is used for showing path information to a remote system.

Since the offset is inconsistent and the clock issues seem to revolve around the system not being powered on it could be a CMOS battery issue. If it were an NTP (port 321) or timezone issue you would likely see a consistent offset. None of these symptoms are typical of an overheating system.

Warehouses are often very dusty, which could cause a fan to stop working and promote overheating. These symptoms (freezing/rebooting) indicate overheating, the noise could be a failing fan. These symptoms do not indicate a battery issue or sticky keys. They could a bad driver, but coupled with the noise it and location is not likely.

Satellite connections often have notable delay/latency issues which would be unacceptable for VoIP and video conferences, they are also negatively impacted by weather. The hand-off for satellite is likely RJ-45 or something similar, you may need a new modem but re-wiring the entire network is an unlikely requirement. Satellite connections can be used with encryption.

Of the options provided DVD-R DL (DVD-Recordable Dual Layer) is the only one with the capacity (8.5GB) to support this. Both CD options have a 0.7GB capacity, and a DVD-R has a 4.7GB capacity.

The only ports that the iPhone 6S and iPad Pro have for interacting with a computer are Lightning ports, thus USB to Lightning cable is the correct answer.

RAID 1 is the only technology that meets the goals stated (redundancy) for the current setup. Dualcore processing is for processing, not storage/backups. RAID 0 is for speed, not redundancy. RAID 5 offers redundancy but requires 3 or more storage devices, you only have 2 HDDs.

RJ-11 supports both a 1 (2 wire) and 2 (4 wire) pair configuration, typically used in telephone systems only 1 pair is traditionally utilized. RJ-45 has 4 pairs (8 wires), Coax has 1 wire, and 4-pin 12V is for power supplies.

The Security tab under Printer Properties on the host computer is where you set the permissions for a shared printer, thus it is the correct answer. There is no Security tab under Printing Preferences which is where you set print quality, paper orientation, etc.

The touchpad is likely damaged or has driver issues, a temporary fix might be disabling it and using a mouse. There is no indication that mouse drivers are causing this problem. The arrow keys and Scroll Lock do not usually influence cursor movement.

A docking station is the only listed choice that will allow you to quickly connect a monitor, network cable, and input devices to the laptop. A cable lock is a physical security device. Monitors do not typically support a wireless connection, and a USB hub does not usually support monitor output or network connections.

These symptoms describe a phone that is in airplane mode. The best option available would be to disable airplane mode. On most smart phones you could also re-enable WiFi and keep Airplane mode.

Each octet of an IP must be between 0-255 but the second octet of this IP is 256. The IP is not an APIPA and DHCP would not affect manually setting a static IP. Classes are used to determine the default subnet mask for an IP but you are not required to use it, therefor the class B address can be used with the class A subnet mask.

Checking the power cable is the most logical answer. You do not know if the power supply is good yet, so replacing it would be premature. These symptoms are not indicative of a CMOS battery issue or a boot sequence issue (also, you can't access the BIOS/UEFI if there is no power).

Port 22 (SSH) is the best answer, SSH is used for secure communications such as console connections to a remote server. Port 23 is for TELNET and is not a secure connection, it is unlikely (or a horrible practice) that TELNET would be used to connect to a sensitive database. Port 80 is for HTTP traffic, not for console connections. Port 3389 is for RDP, and would not usually be used for a console connection but a remote desktop connection.

A hybrid drive will meet these requirements, it is more affordable than an SSD and quicker than a HDD. A tape drive is more of a backup tool, and is slow, not ideal for regular use as described.

255.255.255.128 is the correct answer. Windows does not allow you to input CIDR for network configurations. 255.255.255.192 is a /26 netmask, 255.255.255.0 is a /24 netmask.
