PDF Version DemoSNIA Storage Networking Management & Administration Sample Questions:
1. A customer has a SAS-based storage environment with a SAS domain and some standalone servers, each with multiple built-in SAS disks. The implementation includes direct routing, table routing and subtractive routing. Which role does a fanout expander play in subtractive routing?
A) It forwards routing requests to all other connected edge expanders.
B) It routes between edge expanders connected to it.
C) It disables currently unused branches to increase throughput.
D) It is the sole source of subtractive routing requests in the SAS domain.
2. Your manager has attended an industry event and calls a meeting to discuss some ideas upon his return. One concept that caught his attention was the use of virtual fabrics. What are two (2) advantages of implementing virtual fabric technology? (Choose two.)
A) independent SAN fabric management
B) universally adopted technology
C) isolation of Fault Domains
D) separate fabric services
E) ease of design
3. An application administrator seeks to improve the I/O performance of the server's SAN-attached storage. Which HBA parameter setting change can affect the performance?
A) SCSI ID Mapping
B) Queue Depth
C) PCI Connection Type
D) NL-Port Mode
4. A four-way cluster is attached to two fabrics. Each member has two HBAs connected to each fabric. Each fabric has two subsystem connections. Each cluster member is a primary for one application. All LUNs appear on all storage ports with workload equally distributed across all. Each host has two dedicated HBAs for tape that can each see four independent LTO II (35MB/s) tape drives. All files are large and involve sequential I/O. Performance reporting shows a large read pending at the host during multi-threaded backup. What is the most probably cause for the large read pending at the host?
A) throttling threshold is too high
B) SCSI Queue Depth too low
C) native command queuing
D) SCSI Queue Depth too high
5. The customer has an existing fabric switches installed from one manufacturer.
They have decided to add a redundant fabric using switches from a different manufacturer.
Interoperability is their main concern. What is important when considering interoperability in the SAN?
A) virtualization engine
B) zone naming convention
C) switch interoperability mode
D) HBA firmware/driver code
