You meet a customer for the first time. They explain that their current environment for NAS does not meet their needs. You want to make sure that Isilon is a good fit for their needs.
What would be a good prequalifying question to ask?
- A . What Applications access this storage?
- B . What type of racks are in your datacenter?
- C . Are you using a KVM to access your storage?
- D . How many NICs do your clients have?
Which data access pattern uses moderate prefetching?
- A . Streaming
- B . Mirroring
- C . Random
- D . Concurrency
A customer plans to consolidate 200 TB of digital images and video content. Performance is important for recently created files. However, the customer wants any content that has not been accessed within 30 days to be stored in the cluster at a much lower cost because performance is no longer critical.
Which Isilon configuration should be recommended?
- A . X-Series nodes, NL-Series nodes, and SmartPools
- B . X-Series nodes and SmartQuotas
- C . S-Series nodes, X-Series nodes, and SmartPools
- D . NL-Series nodes and SmartLock
While designing SyncIQ policies for a new cluster, an architect wants to ensure that data is not deleted.
What should the architect create?
- A . SyncIQ copy policy
- B . SyncIQ sync policy
- C . SyncIQ policy with option: "Whenever the source is modified"
- D . SyncIQ policy with Encryption
A customer is evaluating PowerScale and NetApp FAS solutions. They are storing many unique files and want to understand how each solution deduplicates data.
What is the difference between how PowerScale and NetApp FAS deduplicate data?
- A . PowerScale uses separate deduplication at the volume level.
NetApp FAS uses global deduplication across the cluster. - B . PowerScale uses global deduplication across the cluster.
NetApp FAS separates deduplication at the volume level. - C . PowerScale does not have deduplication.
NetApp FAS uses local deduplication. - D . PowerScale uses local deduplication.
NetApp FAS does not have deduplication.
A customer wants to replace a legacy storage environment used for high definition video editing. Each workstation connecting to the shared storage needs to sustain 650 MB/s of single stream bandwidth.
Which node type is recommended?
- A . Performance Accelerator nodes
- B . NL-Series nodes
- C . X-Series nodes
- D . S-Series nodes
The security team at a customer site has created a new requirement that in-flight replication traffic must be encrypted end-to-end. The customer is running OneFS 8.2.1 on their cluster.
What encryption protocol versions does SyncIQ support?
- A . TLS 1.3 and OpenSSL 1.1.1
- B . IPSec 2.1 and OpenSSL 1.0.2
- C . TLS 1.2 and OpenSSL 1.0.2
- D . x.509 13.37 and OpenSSL 0.9.8
A customer has two Isilon clusters in an Active-Passive setup. The customer has latency sensitive media editing workflows. Most of the media editing work occurs prior to broadcasting between 7:00-8:00, 11:00- 12:00, 17:00-18:00 and 19:00-20:00.
What should be recommended to minimize the risk of including latency to the client workflow?
- A . Retain the default job impact policies that would run the Job Engine jobs. Do not run SyncIQ policies during the given hours.
- B . Create and set a custom job impact policy that would exclude the running SyncIQ policies during the given hours.
- C . Create and set a custom job impact policy that would exclude the running of the Job Engine jobs. Do not run SyncIQ policies during the given hours.
- D . Retain the default job impact policies that would run the Job Engine jobs. Run SyncIQ policies during the given hours.
What is a correct statement concerning InsightIQ, excluding FSA?
- A . InsightIQ runs on separate hardware from the cluster and does not take cluster resources beyond the data collection process.
- B . InsightIQ runs on separate hardware from the cluster and provides data used by the isi statistics CLI command set.
- C . InsightIQ runs on the lowest logical node (LNN) on the cluster and provides data used by InsightIQ appliance for graphical output.
- D . InsightIQ runs on the lowest logical node (LNN) on the cluster and provides data used by the isi statistics CLI command set.
You are involved with a Proof of Concept where the performance is not what you expect.
What can you use to collect process stack information and a listing of process waiting on I/O?
- A . netstat
- B . tcpdump
- C . isi statistics
- D . isi_get_itrace
