最新的 EMC Certification E20-554 免費考試真題:

1. A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets.
There is very little space available in the customer's datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives.
What Isilon capabilities can address the customer's concerns?

A) Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
rebuilds.
N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
Data redistribution runs faster with more nodes in the cluster.
B) N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
Proactive hot sparing eliminates most drive rebuilds.
Endurant Cache reduces the overhead for write operations.
C) Isilon nodes have more drives per rack unit so fewer shelves are required.
Proactive hot sparing eliminates most drive rebuilds.
N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
D) Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
rebuilds.
Data recovery is consistent, taking the same amount of time regardless of cluster size.
Isilon 'short strokes' 4TB drives to reduce rebuild time.

2. An Isilon customer expressed an interest in more effectively managing their storage. Specifically, they would like to plan for future growth.
Which tool would allow the customer to forecast capacity requirements?

A) InsightIQ
B) Isilon SNMP MIB
C) SyncIQ
D) SmartPools

3. A healthcare services provider is implementing an X-Series cluster. Currently they have approximately 200 customers and they are growing at 30% per year. They have 200 TB of storage utilized. Health Insurance Portability and Accountability Act (HIPAA) regulations require they keep all patient data for seven (7) years. They would like to keep all genomic sequencing data stored with N+3 protection, not to exceed 75% utilization.
What is the minimum initial configuration you would recommend?

A) 6 X400 nodes; 4 TB drives
B) 7 X400 nodes; 1 TB drives
C) 13 X400 nodes; 1 TB drives

B) How many users are in your Directory Services?
C) Is your datacenter ISO9001 compliant?
D) What application are you using to create directories?

5. You have had several discussions with your customer in the processor design industry. They have stated that they want a Scale-Out NAS platform for their design environment. Their most significant responses were "We have 125 design engineers accessing large diagrams and we need high throughput to support them. Can we also get the highest performance available? We need to stay ahead of our competitors." Other areas you discussed were their data retention policies and workflow after the chip design is completed. They plan to archive the design files but the files must stay on line.
What is your initial node recommendation?

A) A-Series nodes for the active diagrams and X-Series nodes for the archives.
B) X-Series nodes for the active diagrams and NL 400 nodes for the archives
C) X-Series nodes with SSD for the active diagrams and NL nodes for the archives
D) S-Series nodes for the active diagrams and NL Series nodes for the archives
