   What is the primary purpose of redundant power supplies in a compute system?

   • ATo reduce energy consumption by sharing the load between multiple power supplies.
   • BTo increase the overall power capacity of the system for additional components.
   • CTo provide backup power in the event of a complete power outage.
   • DTo allow the system to continue operating if one power supply fails.

   A company runs a critical application on a two-node failover cluster. Each node has dual power supplies and dual NICs. The application data is stored on a shared storage array. The cluster uses a quorum disk. During a routine maintenance, the administrator reboots the active node. The passive node takes over, but the application becomes unavailable for 15 minutes because the passive node's application service fails to start. Which additional compute-based fault tolerance technique would most directly prevent this type of outage?

   • AConfigure the passive node to use RAID 1 for its local disks
   • BAdd a third node to the cluster
   • CEnable live migration between the two nodes
   • DRegularly test failover procedures to validate application startup on the passive node

   A web application is deployed on three identical application servers behind a load balancer. Each server has a local RAID 1 array for its operating system and application files. The load balancer uses round-robin scheduling. One of the servers experiences a network card failure and becomes unreachable. Users continue to access the application without interruption. Which compute-based fault tolerance technique is primarily responsible for this continued availability?

   • AFailover clustering
   • BLoad balancing
   • CRAID 1
   • DLive migration

   A small business runs a file server on a single physical server with four 1 TB disks. The administrator wants to protect against a single disk failure without losing more than one disk's worth of capacity. The server's operating system and applications are installed on a separate RAID 1 array. Which RAID configuration should the administrator use for the data volume?

   • ARAID 6
   • BRAID 5
   • CRAID 0
   • DRAID 1
