Alerts are notifications that inform the technician or the team of any issues or events that occur on a server or a network. Alerts can be configured to trigger based on certain thresholds, such as CPU usage, disk space, memory utilization, or response time. Alerts can help the technician monitor and troubleshoot the server performance in real time. Verified Reference: [Alerts], [Server performance]

A print backup is a type of backup that can be used to mitigate the risk of being unable to access the daily vital records if there is an IT disaster that causes both servers and the network to be offline. A print backup is a backup that involves printing out the data on paper and storing it in a secure location. A print backup can provide offline access to the data without relying on any hardware or software components that may be affected by the disaster. However, a print backup has some drawbacks such as high cost, low efficiency, low security, and environmental impact. A tape backup is a type of backup that involves storing the data on magnetic tape cartridges that can be accessed using a tape drive or a tape library. A tape backup can provide offline access to the data with high capacity, low cost, and long durability, but it requires special equipment and software that may not be available during a disaster. A cloud backup is a type of backup that involves storing the data on remote servers or platforms that can be accessed over the internet using a web browser or an application. A cloud backup can provide online access to the data with high scalability, flexibility, and security, but it requires network connectivity and bandwidth that may not be available during a disaster. A disk backup is a type of backup that involves storing the data on hard disk drives or solid state drives that can be accessed using a computer or a device. A disk backup can provide online or offline access to the data with high performance, reliability, and portability, but it requires compatible hardware and software that may not be available during a disaster.

Replacing hardware components, such as a video card, can sometimes lead to compatibility issues, especially if the system's firmware (BIOS/UEFI) does not support the new hardware. In this scenario, the server operates, and the display functions correctly, but there are performance issues like slow response times. This suggests that while the basic functionality is intact, there may be underlying compatibility problems affecting overall system performance.

A tabletop exercise is a type of disaster recovery testing exercise that is primarily used to discuss incident response strategies for critical systems without affecting production data. A tabletop exercise is a discussion-based session where team members meet in an informal, classroom setting to review their roles and responsibilities during an emergency and their responses to a hypothetical scenario. A facilitator guides the participants through the discussion and evaluates the strengths and weaknesses of the preparedness program.A tabletop exercise does not involve any actual deployment of resources oractivation of systems12. A backup recovery test (B) is a type of disaster recovery testing exercise that involves restoring data from backup media to verify its integrity and availability. A backup recovery test may affect production data if it is not performed on a separate environment. A live failover is a type of disaster recovery testing exercise that involves switching operations from a primary site to a secondary site in case of a failure or disruption. A live failover may affect production data if it is not performed on a simulated environment. A hot-site visit audit (D) is a type of disaster recovery testing exercise that involves inspecting and evaluating a hot site, which is a backup location that has fully operational equipment and resources to resume business operations in case of a disaster.A hot-site visit audit does not involve any discussion of incident response strategies or simulation of scenarios.

The most efficient subnet mask for a point-to-point heartbeat connection between two servers using IP addressing is /30. A /30 subnet mask has 255.255.255.252 as its decimal representation and 11111111.11111111.11111111.11111100 as its binary representation. This means that there are only two bits available for the host portion of the IP address, which allows for four possible combinations: 00, 01, 10, and 11. However, the first and the last combinations are reserved for the network address and the broadcast address, respectively. Therefore, only two IP addresses are usable for the point-to-point connection, which is the minimum required for such a link.A /30 subnet mask is also known as a point-to-point prefix because it is commonly used for point-to-point links between routers or servers1.

A /28 subnet mask has 255.255.255.240 as its decimal representation and 11111111.11111111.11111111.11110000 as its binary representation. This means that there are four bits available for the host portion of the IP address, which allows for 16 possible combinations. However, two of them are reserved for the network address and the broadcast address, respectively. Therefore, 14 IP addresses are usable for the subnet, which is more than needed for a point-to-point connection and would result in wasted addresses.

A /29 subnet mask has 255.255.255.248 as its decimal representation and 11111111.11111111.11111111.11111000 as its binary representation. This means that there are three bits available for the host portion of the IP address, which allows for eight possible combinations. However, two of them are reserved for the network address and the broadcast address, respectively. Therefore, six IP addresses are usable for the subnet, which is still more than needed for a point-to-point connection and would result in wasted addresses.

A /32 subnet mask has 255.255.255.255 as its decimal representation and 11111111.11111111.11111111.11111111 as its binary representation. This means that there are no bits available for the host portion of the IP address, which allows for only one possible combination: all ones. Therefore, only one IP address is usable for the subnet, which is not enough for a point-to-point connection and would result in an invalid configuration.

Therefore, a /30 subnet mask is the most efficient choice for a point-to-point heartbeat connection between two servers using IP addressing because itprovides exactly two usable IP addresses withoutwasting any addresses or creating any conflicts1.
