An administrator is investigating the performance of one of their Dell EMC Isilon clusters. Using the isi statistics drive command, the performance of the first five drives is shown.
Based on the exhibit, what represents the status of the drives?
- A . I/O latency is approximately half a millisecond
- B . Drives operate well within their estimated IOPS limits
- C . I/Os are not queuing due to high latency
- D . Drives exceed their estimated IOPS limits
An IT team is preparing to replicate a dataset from their existing primary Dell EMC Isilon cluster to a secondary cluster. Both clusters are licensed for SmartLock Enterprise and SyncIQ is used for replication. The source directory is a SmartLock directory and the target directory must be a SmartLock directory.
When consulting with the IT team, what is a key consideration before running the replication policy?
- A . Enable WORM on the target directory after the initial synchronization.
- B . Allow OneFS to create the target directory automatically.
- C . Manually create target SmartLock directory before replicating.
- D . Specify the “root” user that can delete files committed to a WORM state.
A company has three Dell EMC Isilon X2000 nodes and needs to configure two subnets on the cluster. The production subnet will only use a 10 GigE-1 port from each node. The second subnet will use both ext-1 and ext-2 ports on each node. The company will access each subnet with its SmartConnect zone name.
Given that the second subnet is isolated with no route to the DNS server, how many IP addresses are needed for each subnet to accommodate the requirements?
- A . 3 for production and 7 for isolated
- B . 4 for production and 6 for isolated
- C . 4 for production and 7 for isolated
- D . 6 for production and 4 for isolated
What enables CloudPools to achieve a recall of data from the cloud?
- A . Creating a HardLink file for every file whose data is archived to the cloud
- B . Creating a SoftLink file for every file whose data is archived to the cloud
- C . Creating a SmartLink file for every file whose data is achieved to the cloud
- D . Creating a copy file for every file whose data is achieved to the cloud
SyncIQ policies are being configured between two Dell EMC Isilon clusters at a company’s location. In addition, the company wants the ability to perform a failover at an Access zone level.
Which actions should be performed to meet the requirement?
- A . Create one NS record delegation per cluster. NS record should always point directly to the cluster SSIP address.
- B . Create one NS record delegation per SmartConnect zone. NS record should always point to an “A” record containing the zone SSIP.
- C . Create one NS record delegation per SmartConnect zone. NS record should always point directly to the SmartConnect zone IP address.
- D . Create one NS record delegation per cluster. NS record should always point to an “A” record containing the cluster SSIP address.
A company uses the Dell EMC Isilon cluster’s A200 nodes for short-team archiving of digitized film. Historical and trending information shows that the cluster capacity will reach 90% full in 60 days. To avoid the need to purchase additional A200 nodes, the company requires a solution that archives data not accessed for 18 months to a more cost-effective platform. The long-term archive data must be online and accessible. Some performance loss is acceptable.
Which IT strategy provides a long-term solution that meets the requirements?
- A . Use data deduplication on achieved data accessed within 180 days
- B . Use SyncIQ to replicate the archive to the H600 nodes on the secondary cluster
- C . Use NDMP to backup to disk using compression and deduplication
- D . Use a CloudPools policy to move the target data to an ECS-powered cloud
A company uses a Dell EMC Isilon cluster to store greater than one billion files. The company often restores files from NDMP backups.
Which backup technology is recommended for the environment?
- A . Two-way NDMP restore
- B . Directory DAR
- C . Three-way NDMP restore
- D . Direct Access restore
A company is planning to replicate a dataset to a newly implemented Dell EMC Isilon cluster. SyncIQ will be used from the source cluster to the target cluster. The company’s systems administrator wants to know how long the initial synchronization will take without seeding.
The administrator provides the following information:
– Link speed between clusters is 1 Gb/s
– Link speed efficiency is 85%
– SyncIQ domain size is 125TB
If no SyncIQ performance rules are set, what is the estimated number of days?
- A . 10
- B . 12
- C . 14
- D . 16
A company has a medical application that generates a large number of media files. The file count is well over one billion and is stored on a Dell EMC Isilon 8-node NL410 cluster. Currently, each node is connected to the network using two 10GbE connections. The Linux-based application does not require high bandwidth; however, it is latency sensitive. Additionally, the Linux hosts are connected to the cluster over NFSv3. The application generates approximately 10,000 files every 10 minutes.
For the past four years, the cluster has been growing at a rate of one additional node per year. The company is running out of free ports on their redundant network switches. They want to know what can be done to ensure continuous availability. They do not want to invest in upgrading the network infrastructure. In addition, the company needs to reduce the number of consumed interface ports on the switches.
Which recommendation should be provided?
- A . Leave the first four nodes of the cluster connected to both network switches with LACP and free up the remaining connections
- B . Leave the first node of the cluster connected to both network switches and free up the remaining connections
- C . Leave the first four nodes of the cluster connected to both network switches and free up the remaining connections
- D . Leave the first 10GbE interface from each node connected to the same network switch and free up the remaining connections
An IT team is implemented a disaster recovery solution. A Dell EMC Isilon cluster will replicate production data from the existing primary cluster to a planned secondary cluster. The primary cluster is licensed for SmartLock Enterprise. A SmartLock enterprise type directory on the primary cluster is planned for SyncIQ replication to the secondary cluster.
When consulting with the IT team.
What is a key consideration when replacing the data in a SyncIQ source directory configured with SmartLock Enterprise mode?
- A . Replication is allowed but a failback will copy the entire dataset
- B . SyncIQ will support a failback regardless of the target’s directory type.
- C . Target directory must be a SmartLock enterprise type.
- D . A SyncIQ policy is not supported on a WORM domain.
