You have been asked to create a LUN on a storage array that is comprised of 7,200 rpm SATA drives. Each drive is rated at 100 IOPS. The LUN should provide a minimum of 1100 IOPS and withstand multiple drive failures using the least number of drives.
How many drives and which RAID level should you use to create this LUN?
You have twelve 500 GB drives and you need to provide two LUNs using RAID 6 protection for a customer.
What will be the size of each LUN?
You are provisioning storage to a host with multipathing software installed and correctly configured. You discover that there are four paths to LUNs instead of the expected eight paths.
Why does this happen?
When troubleshooting an issue on a host, you discover that the existing file system partition has been corrupted after you provisioned a LUN to another host connected to the same FC fabric.
What is the cause of this problem?
A new FC switch has been installed into the data center. You want to disable any unsecure protocols used to access the management ports.
Which two protocols should be disabled? (Choose two.)
Which two high availability elements can be achieved by remote storage replication? (Choose two.)
What are two concerns when trying to migrate from one cloud storage provider to another one? (Choose two.)
You need to implement a solution for a high transaction database which should have the lowest write latency as possible and still be able to sustain a failure of a single drive in a RAID group.
Which type of RAID you would use?
A company needs to replicate a database from its main office to a disaster recovery site 3,000 km away with a five minute recovery point objective.
Which type of replication should the company use to replicate the data?
Some business critical database applications have been suffering from slowly increasing performance issues with one enterprise SAN-attached storage system. In particular, the applications are showing higher than normal read response times.
What should the storage administrator monitor to determine the root cause?
