Five out of 4S servers using one particular enterprise storage system are experiencing performance degradation during normal working hours. All 48 servers have similar workload characteristics. There are multiple disk groups that make up your enterprise storage.
What should be monitored to determine the root cause?
Your company does a full backup on Sunday night and incremental backups from Monday through Saturday at midnight. The full backup requires two tapes and each incremental backup requires one tape. There is a system failure Wednesday morning.
How many tapes will be used to restore to the most current backup?
What is the storage protocol used between initiators and targets connected to an FCoE fabric?
A SAN environment with zones containing a large number of members is experiencing hosts randomly, losing connectivity to SAN-attached storage resources. You have been asked by the customer to address this situation.
Which action should you implement to resolve this issue?
You are using asynchronous storage replication to protect your critical database server. There are no replication agents installed on the database server. After a disaster, you are unable to bring up the database at the DR site.
What is the cause?
You need to merge two existing FC fabrics. After connecting the ISL to join the fabrics, numerous switches segment.
What should be done to prevent the segmentation?
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?
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 two new FC switches from the same vendor and want to connect them together. You have ensured that the domain IDs are unique, switch names are unique, and the firmware levels are identical. When you connect the ISL cables from one switch to the other, the fabric does not merge.
What should be confirmed?
What is the maximum distance between two 8 Gb FC ports that can be connected using 50 µOM3 grade multimode fiber cable?
You are asked to secure management access to your SAN devices.
Which three actions should you perform? (Choose three.)
A server has lost half of its paths to its LUN on a storage system. The help desk determines that one of the two HBAs was just replaced. The SAN administrator has modified the zoning with the new WWPN of the replacement HBA port, but the missing paths have still not recovered.
Which action would you perform next?
After provisioning a new LUN to a host, new storage cannot be detected on the host. Which three actions should be performed to troubleshoot this problem? (Choose three.)
You have completed installing your FC SAN. When everything is powered on, numerous devices are not available. You need to verify that the devices appear within the FC fabric by accessing the appropriate FC service that provides a list of devices and their respective function.
Which server within the Fibre Channel fabric would be used to do this?
