1U stands for one unit and it is a standard unit of measurement for rack-mounted servers. It is equal to 1.75 inches (4.45 cm) in height. A 42U rack can accommodate 42 1U servers or a combination of servers with different unit sizes. Therefore, the unit size per server should be 1U if there are 19 1U servers in a 42U rack.

A DR site is a backup site that can be used to restore business operations in case of a disaster that affects the primary site. A warm site is a DR site that has some equipment and data ready to be activated quickly, but not as fast as a hot site that has fully operational systems and data. A cold site is a DR site that has only basic infrastructure and no equipment or data. The location of a DR site is an important factor to consider when designing and implementing a DR plan. A DR site that is too close to the primary site may be affected by the same disaster, such as a power outage, a flood, or an earthquake. A DR site that is too far away from the primary site may incur higher costs and latency issues. Therefore, a good practice is to set up a DR site that is geographically located in another region that has different risk factors and environmental conditions than the primary site. This can help ensure that the DR site is available and accessible when needed.

GPT (GUID Partition Table) is a partitioning scheme that allows creating partitions on large hard drives (more than 2 TB). It supports up to 128 partitions per drive and uses 64-bit addresses to locate them. MBR (Master Boot Record) is an older partitioning scheme that has limitations on the size and number of partitions (up to 4 primary partitions or 3 primary and 1 extended partition per drive). To provision a new 4 TB drive, the technician should partition it using GPT. Verified References: [GPT], [MBR]

The domain search variable is used to specify a list of domains that are appended to a hostname when resolving it. If the servername is not fully qualified, the resolver will try each domain in the list until it finds a match or fails. By configuring the domain search variable, the technician can avoid typing the full domain name every time they want to ping a server.
