MRU, or Most Recently Used, is a concept that refers to prioritizing a connection that had previously worked successfully. It is often used in load balancing algorithms to distribute the workload among multiple servers or paths. MRU assumes that the most recently used connection is the most likely to be available and efficient, and therefore assigns the next request to that connection. This can help reduce latency and improve performance12. The other options are incorrect because they do not refer to prioritizing a previous connection. Round robin is a concept that refers to distributing the workload equally among all available connections in a circular order12. SCP, or Secure Copy Protocol, is a concept that refers to transferring files securely between hosts using encryption3. Link aggregation is a concept that refers to combining multiple physical links into a single logical link to increase bandwidth and redundancy4.

This is the most likely misconfigured setting because DNS is the service that resolves hostnames to IP addresses and vice versa. If the DNS server is incorrect or unreachable, the administrator will not be able to log on to the server with a domain account because the server will not be able to authenticate with the domain controller.

This is the best description of a synthetic full backup method because it creates a full backup by combining previous incremental backups with the latest backup. An incremental backup copies only the files that have changed since the last backup, while a full backup copies all the files. A synthetic full backup reduces the storage space and network bandwidth required for backups, while also simplifying the restore process by using a single file.

A MD5 checksum is a value that is calculated from a file using a cryptographic hash function. A MD5 checksum is used to verify the integrity of a file by comparing it with the original value provided by the manufacturer or the source. If the MD5 checksums match, it means that the file is authentic and has not been corrupted or tampered with. If the MD5 checksums do not match, it means that the file is potentially corrupt or malicious and should not be installed12. A DLF configuration (A) is a setting that determines how a dynamic link library (DLL) is loaded into memory and executed by an application. A DLF configuration does not check the integrity of a file. A MBR failure (B) is a problem that occurs when the master boot record (MBR) of a disk is damaged or corrupted, preventing the system from booting. A MBR failure does not check the integrity of a file. ECC support © is a feature that enables error-correcting code (ECC) memory to detect and correct data errors in RAM. ECC support does not check the integrity of a file.
