A technician deployed a VM with NL-SAS storage to host a critical application. Two weeks later, users have begun to report high application latency. Which of the following is the best action to correct the latency issue?
Explanation:
The high latency issue is likely due to the slow performance of NL-SAS (Nearline SAS) storage, which is a lower-tier, high-capacity storage option but not optimized for high-speed operations.
✔ Flash storage (SSD) provides significantly lower latency and higher IOPS (Input/Output Operations Per Second) compared to NL-SAS and even SAS storage.
✔ Migrating the critical application’s data to flash storage will result in faster read/write speeds, reducing application latency and improving performance.
D. Migrate the data to flash storage.
The best action to correct the latency issue is to migrate the data to flash storage. NL-SAS (Nearline Serial Attached SCSI) storage typically offers lower performance compared to flash storage, which includes SSD (Solid State Drive) technology. Flash storage provides faster read and write speeds, lower latency, and better overall performance compared to traditional spinning disks like NL-SAS.
