AWS CERTIFIED SYSOPS ADMINISTRATOR –
ASSOCIATE EXAM 2025 QUESTIONS AND
ANSWERS
Elasticity as a SysAdmin (2) - ....ANSWER ...-1) Elasticity allows your application
to "stretch" out and "retract" back in based off of utilization.
2) Pay-for-what-you-need concept.
Causes for Instance Status Checks (5) - ....ANSWER ...--Failed System Checks
-Misconfigured networking or startup configuration
-Exhausted memory
-Corrupted file system
-Incompatible kernel
Instance Status Checks (resolution) (2) - ....ANSWER ...-1) Reboot the instance.
2) Make modifications to the operating system.
Causes for System Status Checks (3) - ....ANSWER ...--Loss of network
connectivity
-Loss of system power

, -Software issues on the physical host
Resolutions for System Status checks (2) - ....ANSWER ...--Start/stop the
instance(might change the physical host- unless using dedicated tenancy)
-Terminating and building a new instance
Base IOPS & Burstable Duration : Formula (3) - ....ANSWER ...--Base IOPS =
Volume Size x 3
-Burstable Duration = Credit Balance/(Burst IOPS)-3(Volume Size GIB)
-3000 IOPS = Max Burst Size
EBS I/O Credits: Facts and #'s - ....ANSWER ...-- I/O Credits initial balance of
5,400,000 will sustain 3,000 IOPS for 30 minutes
- Credits are earned every second a volume is at a base IOP rate of 3 IOP per GiB of
volume size
- Larger volumes have higher base performance levels and accumulate I/O credits faster
- The more credits a volume has, the more time it can burst beyond its base performance
level
- If I/O credit is used, then the volume will stay at base performance regardless of
demand
- The larger the volume, the better the performance and faster it replenishes the I/O
credit balance
"Read then Write Back" Method - ....ANSWER ...-- Used when pre-warming an
EBS volume that is created from a snapshot
