Exam 2: Storage Networking Management and Administration

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?

You are installing an OLTP application on a new server. The I/O profile of the application consists of 100% random read operations of 8 kilobyte transfers. You need to determine which HBA to use in your application to accommodate 50,000 IOPS. What is the minimum FC link speed that will satisfy the application's requirements?

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?

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

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 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?

What should be considered when implementing remote replication of storage?

Which type of storage replication is required, at a minimum, for a non-critical application?

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

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?

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?

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?

You are asked to set up a server to boot from a SAN. Which setting on the HBA needs to be configured?

What is the storage protocol used between initiators and targets connected to an FCoE fabric?

You are asked to secure 2.5 PB of data so that in case of a failed drive replacement, data on the drives is not usable. Which data protection method should be used in this case?

A storage networking device has experienced a failure that has "phone home" and opened a service request for a part that can be a customer replaceable unit (CRU). Your support vendor has dispatched a replacement part using a secure courier service. According to SNIA Storage Security Best Current Practices, which statement is correct about the repair process?

Which process allows for the reduction of disk space consumption on a shared storage of OS images used by 200 users?

A security audit reveals deficiencies in your company's FC zoning practices. Your manager asks you to make a recommendation to implement the most secure FC zoning possible. Your company is using switches from a single vendor. What do you recommend?

Click the Exhibit button. Your company has purchased a new storage array that has dual management access network ports. You need to connect the array and provide maximum redundancy without affecting production traffic. Referring to the exhibit, where should the ports be attached?

Only one of many servers has poor performance within an enterprise SAN. The server administrator has found high disk timeout values without a decrease in throughput. The server has multiple paths to the storage system but only one path is active at this time. What should the storage administrator monitor to assist with troubleshooting?
