Security+ (Incident Response) ACTUAL
UPDATED QUESTIONS AND CORRECT
ANSWERS
Redundant Power Supply - CORRECT ANSWERS✅✅An enclosure that provides two or
more complete power supplies
Surge - CORRECT ANSWERS✅✅An unexpected increase in the amount of voltage
provided
Spike - CORRECT ANSWERS✅✅A short transient in voltage that can be due to a short
circuit, tripped circuit breaker, power outage, or lightning strike
Sag - CORRECT ANSWERS✅✅An unexpected decrease in the amount of voltage provided
Brownout - CORRECT ANSWERS✅✅Occurs when the voltage drops low enough that it
typically causes the lights to dim and can cause a computer to shut off
Blackout - CORRECT ANSWERS✅✅Occurs when there is a total loss of power for a
prolonged period
Uninterruptible Power Supply (UPS) - CORRECT ANSWERS✅✅Combines the
functionality of a surge protector with that of a battery backup
Backup Generator - CORRECT ANSWERS✅✅An emergency power system used when
there is an outage of the regular electric grid power
Redundant Array of Independent Disks (RAID) - CORRECT ANSWERS✅✅Allows the
combination of multiple physical hard disks into a single logical hard disk drive that is
recognized by the operating system
RAID 0 - CORRECT ANSWERS✅✅Provides data striping across multiple disks to increase
performance
, RAID 1 - CORRECT ANSWERS✅✅Provides redundancy by mirroring the data identically
on two hard disks
RAID 5 - CORRECT ANSWERS✅✅Provides redundancy by striping data and parity data
across the disk drives
RAID 6 - CORRECT ANSWERS✅✅Provides redundancy by striping and double parity
data across the disk drives
RAID 10 - CORRECT ANSWERS✅✅Creates a striped RAID of two mirrored RAIDs
(combines RAID 1 & RAID 0)
Fault-resistant RAID - CORRECT ANSWERS✅✅Protects against the loss of the array's
data if a single disk fails (RAID 1 or RAID 5)
Fault-tolerant RAID - CORRECT ANSWERS✅✅Protects against the loss of the array's data
if a single component fails (RAID 1, RAID 5, RAID 6)
Disaster-tolerant RAID - CORRECT ANSWERS✅✅Provides two independent zones with
full access to the data (RAID 10)
Cluster - CORRECT ANSWERS✅✅Two or more servers working together to perform a
particular job function
Failover Cluster - CORRECT ANSWERS✅✅A secondary server can take over the function
when the primary one fails
Load-balancing Cluster - CORRECT ANSWERS✅✅Servers are clustered in order to share
resources such as CPU, RAM, and hard disks
Hot Site - CORRECT ANSWERS✅✅A near duplicate of the original site of the
organization that can be up and running within minutes
