A cache battery is a battery that provides backup power to the cache memory of a disk array controller. The cache memory stores data that is waiting to be written to the disk array. If the cache battery fails, the data in the cache memory may be lost or corrupted when the power is interrupted. Verified

NIC teaming is a feature that allows the use of multiple network interface cards (NICs) as a single logical interface with a single IP address. It can improve the network performance, bandwidth, and redundancy of a server. Verified

The audit.log file is a file that records security-related events on a Linux server, such as user login, file access, and system commands. The logrotate utility is a tool that rotates, compresses, and deletes old log files based on certain criteria, such as size, time, or frequency. To decrease the number of times the log rotates without losing any information, the administrator should increase the audit.log file size in the appropriate configuration file, such as /etc/logrotate.conf or /etc/logrotate.d/auditd. Verified

DLP (Data Loss Prevention) is a security measure that prevents unauthorized copying, transferring, or leaking of sensitive data from a server or a network. It can block or alert the user when they try to copy a file to certain locations, such as a network share or a USB flash drive, based on predefined policies and rules. Verified

CIFS (Common Internet File System) is a protocol that allows file sharing across different operating systems, such as Unix and Windows. It supports read and write access to files and folders on a network share. It is also known as SMB (Server Message Block). Verified

A host firewall is a software that controls the incoming and outgoing network traffic on a server based on predefined rules and filters. It can block or allow certain ports, protocols, or addresses that are used for communication with other servers or devices. If a server is unable to connect to another server after applying a patch, it is possible that the patch changed or added a firewall rule that prevents the connection. The administrator should check the host firewall rule and modify it if necessary to restore connectivity. Verified

A blade server is a type of server that is installed in a chassis or an enclosure that provides power, cooling, networking, and management features. The blade server does not have any cables attached to it, as it connects to the chassis through a midplane or a backplane. A blade server can save space, energy, and cost compared to other types of servers. Verified

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

JBOD (Just a Bunch Of Disks) is a storage configuration that combines different types and sizes of hard drives into one logical unit without any RAID level or redundancy. It allows users to see all the drives within the unit as one large storage space. JBOD can utilize all the available capacity of the drives but does not provide any performance or fault tolerance benefits. Verified
