CompTIA Server+ SK0-005 Release Date

The server has a CMOS battery failure and the time synchronization service is disabled on the servers. The CMOS battery is a small battery on the motherboard that powers the BIOS settings and keeps track of the date and time when the server is powered off. If the CMOS battery fails, the server will lose its configuration and display an incorrect date and time when it is powered on. This can cause access issues for users and applications that rely on accurate time stamps. The time synchronization service is a service that synchronizes the system clock with a reliable external time source, such as a network time protocol (NTP) server. If the time synchronization service is disabled on the servers, they will not be able to update their clocks automatically and may drift out of sync with each other and with the network. This can also cause access issues for users and applications that require consistent and accurate time across the network.

A hot site is a type of disaster recovery site that has all the equipment and data ready to resume operations as soon as possible after a disaster. A hot site is usually located in a different geographic area than the primary site and has redundant power, cooling, network, and security systems. A hot site is best for the company that wants to recover in the shortest possible time and does not want customer data to egress to non-company equipment. A warm site is a type of disaster recovery site that has some equipment and data ready, but requires some configuration and restoration before resuming operations. A cold site is a type of disaster recovery site that has only basic infrastructure and space available, but requires significant setup and installation before resuming operations. Cloud recovery is a type of disaster recovery service that uses cloud-based resources and platforms to store backups and restore data and applications after a disaster.

The write cache is a feature of some RAID controllers that allows them to temporarily store data in a fast memory buffer before writing it to the disk drives. This improves the performance and efficiency of write operations, especially for random and small writes. However, if the battery on the controller goes bad, the controller may disable the write cache to prevent data loss in case of a power failure. This can degrade the disk drive performance significantly, as every write operation will have to wait for the disk drives to complete.

The storage protocol that the administrator is most likely using to save data to the location \server1\ITDept\ is CIFS. CIFS (Common Internet File System) is a protocol that allows file sharing and remote access over a network. CIFS is based on SMB (Server Message Block), which is a protocol that enables communication between devices on a network. CIFS uses UNC (Universal Naming Convention) paths to identify network resources, such as files or folders. A UNC path has the format \servername\sharename\path\filename. In this case, server1 is the name of the server, ITDept is the name of the shared folder, and \ is the path within the shared folder.
