Question 1
An administrator is connecting a Linux host to a PowerStore appliance and must know which storage network interface to use.
Which nvme subcommand should be used?
Answer : D
Understanding NVMe-oF and the nvme Utility
NVMe over Fabrics (NVMe-oF): This technology allows NVMe storage to be accessed over a network fabric, such as Ethernet or InfiniBand. It provides high performance and low latency for demanding applications. PowerStore supports NVMe-oF, enabling efficient connectivity for Linux hosts.
nvme Utility: Linux systems use the nvme command-line utility to manage and interact with NVMe devices, including those accessed over a network. This utility provides various subcommands for tasks like discovering targets, connecting to them, and managing namespaces.
Why nvme discover is Essential
Discovering NVMe-oF Targets: The nvme discover subcommand is crucial for identifying the available NVMe-oF targets (like your PowerStore appliance) on the network. It scans the network based on the specified parameters (transport type, address range) and returns information about the discovered targets.
Identifying Storage Network Interfaces: The output of nvme discover includes details about the target's network interfaces, such as their addresses, transport types (e.g., TCP, RDMA), and NQN (NVMe Qualified Name). This information is essential for the administrator to determine the correct network interface to use when connecting the Linux host to the PowerStore appliance.
Example Usage
Bash
nvme discover -t tcp -a 192.168.1.0/24
This command would discover NVMe-oF targets that are accessible over TCP within the specified subnet. The output might look something like this (simplified):
Discovery Log Number of Records 1, Generation counter 2
=====Discovery Log Entry 0======
trtype: TCP
adrfam: IPv4
treq: not specified
portid: 8009
trsvcid: 4420
subnqn: nqn.2014-08.org.nvmexpress:uuid:01234567-89ab-cdef-0123-456789abcdef
traddr: 192.168.1.10
This output shows the target's NQN, transport type (TCP), IP address (192.168.1.10), and the port used for communication (8009).
Dell PowerStore Reference
While the nvme discover command is a general Linux utility, here are some Dell PowerStore resources that provide context for connecting Linux hosts:
PowerStore Host Configuration Guide: This guide provides comprehensive information about configuring different types of hosts, including Linux hosts, to connect to PowerStore. It covers various connectivity options and best practices. You can find the latest version of this guide on the Dell Support site.
By using nvme discover, the administrator can gather the necessary information about the PowerStore appliance's network interfaces and ensure proper connectivity for the Linux host.
Question 2
SIMULATION
An administrator must configure a new protection policy for an existing VM with the following parameters.
Rule Name: 2x5x14
Days: M-F
Every: 12 Hours
Retention: 14 Days
Access Type: Snapshot
Policy
Name: Bronze
Snap Rule: 2x5x14
Apply the policy to VM1.
When you have finished continue to the next question.
Answer : A
Question 3
SIMULATION
A storage administrator needs to group Volume-1 and Volume-2 for consistency. The group should have a snapshot every day that is retained for 25 hours.
Use the simulator to make this configuration change.
When you have finished continue to the next question.
Answer : A
1. Open the simulator and log in with the default credentials: admin/Password123#.
2. SelectStorage>Volumesfrom the left menu.
3. SelectVolume-1andVolume-2from the list of volumes and clickGroup.
4. Enter a name for the volume group, such asConsistent-Group, and clickCreate.
5. SelectProtection>Protection Policiesfrom the left menu.
6. Click+ CREATEto launch the Create Protection Policy wizard.
7. Enter a name for the protection policy, such asDaily-Snapshot, and clickNext.
8. Click+ CREATEto create a new snapshot rule for the policy.
9. Enter a name for the snapshot rule, such asDaily-Rule, and clickNext.
10. SelectAll Daysfor the days to run the rule andTime of dayfor the frequency. Enter00:00as the start time and clickNext.
11. Enter25as the retention hours and clickNext.
12. Review the summary and clickFinishto create the snapshot rule.
13. ClickNextto continue the protection policy wizard.
14. Review the summary and clickFinishto create the protection policy.
15. SelectStorage>Volume Groupsfrom the left menu.
16. SelectConsistent-Groupfrom the list of volume groups and clickEdit.
17. ClickProtection Policyand selectDaily-Snapshotfrom the drop-down list. ClickSave.
18. The volume group is now configured with a protection policy that creates a snapshot every day at 00:00 and retains it for 25 hours.
Question 4
Which three features are included in PowerStore X licensing? (Choose three.)
Answer : A, D, E
Question 5
SIMULATION
In a PowerStore T source cluster create a 100GB volume with name ''Prod_vol'' with a category of ''Other''. Set its protection policy to replicate the volume with an RPO of 30 minutes to Cluster1. The destination cluster is already configured.
When you have finished, continue to the next question.
Answer : A
1. Log in to the PowerStore Manager of the source cluster.
2. From the top menu, click Storage and select Volumes from the drop-down list
3. Click Create and enter the following information:
4. Name: Prod vol
5. Description: (optional)
6. Quantity: 1
7. Size: 100 GB
8. Application Tag: Other
9. Click Next and select the protection policy that has a replication rule to Cluster1 with an RPO of 30
minutes. If there is no such policy, click Create and follow the steps to create a new protection
policy with a replication rule
10. Click Next and review the summary of the volume creation.
11. Click Create to create the volume and start the replication session to Cluster1.
Question 6
SIMULATION
Use the simulator to create a new 100 GB volume. Use a category of Other. Associate the new volume with a protection policy that includes a rule that takes a snapshot every hour Monday-Friday and retains it for 5 days.
When you have finished continue to the next question.
Answer : A
1. Create the Volume
Navigate to Storage > Volumes.
Click + CREATE.
Enter a name for the volume (e.g., 'MyVolume').
Set the volume size to 100 GB.
In the 'Category' dropdown, select Other.
Click Add.
2. Create the Protection Policy
Navigate to Protection > Protection Policies.
Click Add Protection Policy.
Enter a name for the policy (e.g., 'HourlySnapshots').
Click Next.
3. Configure the Snapshot Rule
In the 'Snapshot Rules' section, click Add Rule.
Enter a name for the rule (e.g., 'HourlyRule').
Set the Days to Monday through Friday.
Set the Every field to 1 Hour.
Set Retain to 5 Days.
Click Add.
Click Next.
4. Review and Finish
Review the protection policy summary.
Click Finish.
5. Associate the Protection Policy with the Volume
Navigate back to Storage > Volumes.
Locate the 100 GB volume you created.
Click the More Actions button (three vertical dots) and select Edit.
In the 'Protection Policy' field, select the newly created HourlySnapshots policy from the dropdown list.
Click Save.
Verification
To verify the configuration, go to Protection > Protection Policies.
Select the HourlySnapshots policy.
You should see the configured snapshot rule ('HourlyRule') with the specified settings.
Key Considerations
Snapshot Frequency: The snapshot rule you created will take hourly snapshots of the volume every weekday (Monday to Friday).
Retention Period: The snapshots will be retained for 5 days before being automatically deleted.
Storage Space: Snapshots consume storage space. Ensure you have enough free space to accommodate the snapshots taken based on the frequency and retention period.
By following these steps, you'll successfully create a 100 GB volume, configure a protection policy with the specified snapshot rule, and associate the policy with the volume, fulfilling the requirements of the simulation task.
