Exam 2: Storage Networking Management and Administration

Click the Exhibit button. 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 have determined that the root cause of your problem is related to invalid characters being intermittently transmitted on your 4 Gb FC link. What describes this condition?

Your company's Service Level Agreement (SLA) requires that no more then one hour's worth of data be lost in case of a system crash. The data must also be restored within 10 hours. Which two RTO/RPO combinations meet the SLA? (Choose two.)

What is the maximum distance between two 8 Gb FC ports that can be connected using 50 µOM3 grade multimode fiber cable?

You have a new storage array with the following drive types: 1. SAS (6 Gbps) 2. SSD 3. SATA (6 Gbps) 4. FC(4Gbps) You need to decide which drive type to use based on speed, cost, and drive availability for your Tier 1 storage. Which type of drive would you choose?

A business critical enterprise resource planning (ERP) system uses a central database at a company's primary data center. The company has built an out-of-region disaster recovery data center and intends to implement a standby ERP system with an eight hour RTO and 30 minute RPO. Which architectural approach to implement service continuity for the ERP database will meet the RTO and RPO targets?

You want to visibly verify FC port initialization by reading an analyzer trace. Your objective is to find the frames associated with the initialization protocol to ensure that the FC device is operating correctly during the login process, to be recognized as part of the switched fabric, and appear in a directory of attached FC devices. What must all Fibre Channel devices do to accomplish this?

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?

Which type of a backup changes the archive bit?

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 are designing a security solution for a storage array which stores customer credit card information. Data on the storage array must be encrypted and if necessary, you want to be able to revoke access to data on demand. In addition to encryption, which solution would allow you to do this in a secure and automated fashion?

Click the Exhibit button. Referring to the exhibit, which backup type is represented?

You determine that throughput between a server and an FC storage array is lower than expected. Your privileges only allow you to change the configuration of the HBA on the server. Which configuration setting can you change to increase throughput?

Which storage related offering serves as intermediaries to multiple cloud storage providers?

You need to add an iSCSI host and storage array to your environment. Your manager wants at least two options that allow all iSCSI initiators to query a central management server to locate the address of all iSCSI resources (e.g., iSCSI initiators, targets, switches, and management stations). Which two protocol methods would be used? (Choose two.)

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?

The CIO would like to segregate management device IP network traffic from server IP network traffic within the data center to limit potential security threats. What would be used to accomplish this?

Click the Exhibit button. Referring to the exhibit, which RAID level is shown?

You have been asked to secure your FC switches in the data center. Unsecure protocols have already been disabled but you also need to restrict access to the switches only from specific IP addresses located on the production network. What should be used?

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.)
