Storage Networking Management and Administration v6.0

You have been hired as a consultant to help resolve boot-from-SAN server reboots. The company has hosts, storage devices, and tape drives in the same zones. A large number of RSCNs are generated during the backup window.
What is the cause of the problem?

A storage subsystems Web browser management interface reports that the subsystem has become degraded and remotely opens a service request with the vendor. Your vendors level three storage support engineer wants to remotely access your storage subsystem for troubleshooting.
What is a SNIA Storage Security Best Current Practices solution?

Which standard would be used to increase interoperability between solutions of different cloud storage providers?

Referring to the exhibit, which three switch indicators will help you to determine the stability of a link? (Choose three.)

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?

Which two high availability elements can be achieved by remote storage replication?
(Choose two.)

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?

Your company uses a cryptographic key system to encrypt tapes. After several years of use and thousands of tapes shipped to off-site locations, an IT audit reveals that encryption keys have been inadvertently stored as ciphertext on file shares to which everyone in the company has read permissions.
Which response reflects industry best practice?

Which RAID level is shown in the exhibit?

The customer configuration shown in the exhibit is not meeting the throughput needs of a newly installed application. The application's I/O profile consists of 100% 4 kilobyte reads and all servers require a sustained bandwidth of 150 MBps.
Which location within the configuration presents a performance bottleneck?

You receive a ticket from a database group which is complaining about slow access to storage on only one particular server, as compared to other servers in an active-active cluster. You verify zoning and LUN masking which are fine. On the FC switch, you verify link speed, errors, and throughput for the FC switch ports used by this server. There are no errors on the ports and the link speed is the same as on the switch ports used by other servers in the cluster. You notice that on one port on the FC switch used by this server, that there is no throughput at all.
What is causing the problem?

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?

Click the Exhibit button.
The customer application requires a 50/50 R/W ratio with 100 MBps throughput requirements for each direction of the link. The application servers will simultaneously sustain these data rates across all LUNs in parallel.
Referring to the exhibit, where will the oversubscribed link(s) occur?

Which protocol commonly uses CNA devices?
