Which actions could the SysOps administrator take to accomplish this goal?
(Choose two.)
Restore the EBS volume from the snapshot with fast snapshot restore enabled.
Restore the EBS volume from the snapshot using the cold HDD volume type.
Restore the EBS volume from the snapshot and pre-warm the volume by reading all of the blocks.
Restore the EBS volume from the snapshot and configure encryption.
Restore the EBS volume from the snapshot and configure I/O block size at random.
Explanations:
Enabling Fast Snapshot Restore (FSR) reduces the time it takes for a snapshot to be restored and ensures that the volume is fully available and optimized for consistent performance.
Using the cold HDD volume type is not suitable for Provisioned IOPS volumes as it is designed for infrequent access and cannot provide the required consistent I/O performance.
Pre-warming the EBS volume by reading all of its blocks ensures that the volume is fully initialized and ready for consistent performance, eliminating I/O latency due to initialization.
Configuring encryption is unrelated to improving I/O performance consistency. Encryption may add some overhead but does not impact the variability of I/O performance.
Configuring I/O block size at random may lead to inconsistent performance, as it introduces unpredictability in the workload, which contradicts the goal of achieving consistent I/O results.
If I’m not mistaken, the answer is:
Restore the EBS volume from the snapshot with fast snapshot restore enabled.
