snia s10-300 practice test

You notice, from continually monitoring a SAN arry, that an array has a number of soft SCSI bus error.
You trace the errors back to a single drive using a vendor's event tool. Which two would correct this?
(Choose two)

• A. You should pull the drive out immediately and replace it to prevent data corruption on the RAID set.
• B. Soft SCSI bus errors can be safely ignored as they do not actually denote any service requirements.
• C. You should research the error to determine the impact and proper response including the vendor in these discussions
• D. Review the logs from the array to identify if there is a pattern of large numbers of these SCSI errors. A large number of these SCSI bus errors may denote a predictive failure.

Company.com has implemented a disaster recovery (DR) plan with remote standby servers and
synchronous data replication. The customer wants to upgrade to 2 Gb HBAs in a server. What should
be done before shutting down the production server and upgrading the HBA?

• A. Failover the storage and applications to the remote facility, shut down production servers and upgrade the HBA
• B. Create a copy-on-write (COW) snapshot and present it to a local host, failover applications, shut down productions servers and upgrade the HBA, delete snapshot.
• C. Creat a split mirror snaphot and present it to a local host, failover applications, shut down production servers and upgrade the HBA, reestablish the snapshot
• D. Create a COW snapshot of the production volume and present it to a remote host, failover applications, shut down production servers and upgrade the HBA, delete snapshot

You are conducting an ILM assessment and just completd the consolidation and assignment phase.
What is your next steps?

• A. Perform gap analysis
• B. Develop detailed design
• C. Collect data and requirements
• D. Prepare actionable recommendations

After lab testing a solution, which two deliverables should be presented to the implementation
team? (choose two)

• A. List of tested and approved versioning and code
• B. Performance metric showing maximum performance
• C. Complete TCO and ROI documentation for the solution
• D. Tested procedures and process for failover and redundancy

A disaster recovery (DR) Plan includes synchronously replicating data between a production and
Remote site and implementing a to-member extended distance cluster. Company.com uses a
database application that can run in parallel mode. What should Company.com do?

• A. Start the database in parallel mode so that it runs on both servers;failover the storage in a disaster
• B. Start the database in parallel mode so that it runs on both servers;you do not need to failover anything.
• C. Run the database in normal mode on the production cluster member and failover the application and storage in a disaster
• D. Run the database in normal mode on each cluster member with each accessing local database files; you do need to failover anything.

Which technique is used to ensure that SAN-attached tape devices are represented consistently in a
host operating system?

• A. LUN mapping
• B. Persistent binding
• C. Fabric initialization
• D. Indexed addressing

You are architecting a redundant SAN which will include 100 hosts with dual HBAs,50 hosts with
Quad HBAs, and storage arrays which have a total of 48 ports. The SAN implements redundant
Fabrics and redundant ISLs. A 128 port director is ten times as expensive as a 16 port switch.
Focusing on management, cost, performance, and future expansion, which solution is the most
effective?

• A. 4 directories
• B. 32 switches in a mesh configuration
• C. 2 directors and 16 switches in a mesh configuration
• D. 2 directors and 16 switches in a core edge configuration

A new host is added to the SAN. The SAN includes 200 hosts. The administrator is providing the Host
with one virtual device. What should be done?

• A. Create a logical volume on the array, configure LUN masking, rescan the SCSI bu.
• B. Create a logical volume on the array zone the host to the array ports, configure LUN masking, rescan the SCSI bus.
• C. Create a logical volume on the array configure LUN masking, zone the host to the array ports, rescan the SCSI bus.
• D. Create a logical volume on the array configure LUN mapping, zone the host on the array ports, rescan the SCSI bus.

A client has four servers they want to attach to a storage array containing 16 ports. Which topology is
the most cost effective for this situation?

• A. Star
• B. Mesh
• C. Point-to-point
• D. Switched Fabric

A four switch Fabric with 8 ports per switch using a full-mesh connectivity approach will have 20
Ports available for Fabric attached devices. How many ports will be available using the full mesh
approach when increasing the number of switches from four to six?

• A. 12
• B. 18
• C. 20
• D. 24
