SNIA S10-300 real exam prep : Snia Storage Architect-Assessment,Planning and Design

Which design supports high availability and no single point of failure for storage networks along With performance and scalability?

• A. Clustered serverswith a single host adapters attached to switches that have redundant paths to storage subsystems.
• B. A large single Fabric with any to any connectivity between all switches
• C. High quality fiber optic cabling transceivers cable management and diagnostic tools.
• D. Dual and quad ported servers and storage devices attached to a dual fabric.

A company is designing a Disaster Recovery (DR) plan. They have an RPO of zero. The DR site is located 250km from the production site. The DR plan must not affect application performance at the production facility. Which scenario is appropriate?

• A. Synchronously replicated the data to the DR site
• B. A new DR site must be chosen
• C. Create a split mirror snapshot and replicate the snapshot to the DR site
• D. Asynchronously replicated the data to the DR site

A client is consolidating a database server into an existing SAN attached array with 73 GB drives and a default LUN size of 8.8 GB. The server currently uses O/S based volume management on 9 GB LUNs carved from 36 GB drives in a direct attached disk array. The array is connected using two 100 MB/s FC ports. The file systems are set at a default blocksize of 2048. Which would be the most important to address in your design?

• A. Adapt to standard LUN sizes, paying migrationpenalities
• B. Determine capacity/performance impact of file system parameters
• C. Upgrade connectivity from 100 to 200 GB, incurring upgrade cost
• D. Account for change in access density from 36 GB to 73 GB drive

An existing SAN has been experiencing numerous faults in the past few months, you have been Tasked with bringing the problems to solution and ensure reliability. Your primary concern is visibility into the SAN and the present lack of monitoring. Which two are true about the existing infrastructure? (Choose two)

• A. Since SMI-S is an emerging standard, the likehood of being able to manage equipment bought in previous years is very low. A migration plan should be considered to an SMI-S complaint infrastructure.
• B. Requesting vendor assistance, and if need be custom builds of the firmware/software that runs your array to fix the specific problems that you encounter.
• C. Evaluating vendor supplied tools, and knowledge base type documents may outline best practices for increasing reliability and reporting.
• D. Testing and then Level settings firmware and code levels to a common vendor supported standard will allow you to avoid many of the problems that may have been encountered in the past.

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 configure LUN mapping, zone the host on the array ports, 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 zone the host to the array ports, configure LUN masking,rescan the SCSI bus.
