Application clusters {Ans: Active-Passive - application only runs on one active node, while the other passive nodes are used only if the application fails on the active node. One of the major ways to ensure application availability and DR Active-Active - the application runs on every node of the cluster. With this setup, cluster agents coordinate the information processing between all of the nodes, providing load balancing and coordinating concurrent data access. Puts a greater demand on network latency. Often, orgs will use a combination of cluster setups.}Orphan Data {Ans: Data lost during a disaster that is unrecoverable}Maximum Tolerable Outages {Ans: Maximum time the org can support processing in alternate mode. After this point, problems may arise, especially if the alternate SDO is lower than the usual SDO.}Unshielded Twisted Pair (UTP) {Ans: in copper will reduce the likelihood of crosstalk.}Operator problem reports {Ans: Manual reports are used by operators to log computer operations problems and their resolutions. Way to monitor the efficiency and effectiveness of services provided by IT personnel.}Library Control Software {Ans: Should be used to separate test from production libraries in mainframe and/or client server environments. The main objective of library control
