A 1000BASE-LX 1Gb single-mode plenum fiber connection would best meet the analyst's needs for a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. A 1000BASE-LX is a type of Ethernet standard that supports data transmission at 1 gigabit per second over single-mode fiber cables using long wavelength lasers. A single-mode fiber cable is a type of optical fiber cable that has a small core diameter and allows only one mode of light to propagate through it. A single-mode fiber cable can transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A plenum fiber cable is a type of optical fiber cable that has a special coating that prevents the spread of fire or toxic fumes in case of burning. A plenum fiber cable is suitable for installation in plenum spaces, which are areas used for air circulation in buildings, such as above ceilings or below floors.

Explanation
An out-of-band (OOB) solution is a method of accessing and managing a server remotely without using the network connection or the operating system of the server. An OOB solution can use a dedicated management port, a serial console, or a KVM switch to provide a resilient connection while performing changes to the network configuration of the server. An OOB solution is more reliable than a VNC or RDP console, which depend on the network and the operating system, and more convenient than a crash cart, which requires physical access to the server.

Explanation
DLP (Data Loss Prevention) software is a type of security software that monitors and controls the transfer of sensitive or confidential data outside the organization. DLP software can prevent data breaches, data leaks, or data theft by blocking, encrypting, or alerting on unauthorized data transfers. DLP software can be applied to various channels, such as email, web, cloud, or removable devices.
In this scenario, the human resources analyst is attempting to email the records for new employees to an outside payroll company. The records for new employees may contain sensitive or confidential data, such as personal information, tax information, or bank account information. The DLP software may detect this data and block the email from being sent outside the company, as it may violate the company's data protection policy or regulations. The DLP software may also generate an error message to inform the analyst of the reason for the rejection.

The first thing that the administrator should check is the network cable. The network cable is a physical medium that connects a server to a switch or other network device. The network cable can affect the speed and quality of the network connection, depending on its type, length, and condition. If the network cable is damaged, faulty, or incompatible, it can cause the server to connect at a lower speed than expected. Therefore, the administrator should check the network cable for any signs of wear, tear, or mismatch, and replace it if necessary.
