#9 - Certified FlashArray Storage Professional

A VMware administrator is configuring a new NVMe-oF datastore on an ESXi host. They need to ensure that the multipathing configuration is optimized for performance. Which command should they use to verify the current claim rules?

• `esxcli storage core claimrule add`

• `esxcli storage core claimrule list`

• `esxcli storage hpp device list`

• `esxcli storage core claimrule load`

After applying a new claim rule for NVMe devices, the administrator notices that the changes do not reflect immediately. What must they do to apply the changes to existing datastores without restarting the host?

• Run `esxcli storage core claimrule load`

• Reboot the host

• Use the GUI to apply changes

• Run `esxcli storage hpp device set`

An IT team is investigating latency issues on their NVMe-oF storage. They decide to switch to a latency-based path selection policy. What command do they use to change the path selection scheme for a specific device?

• `esxcli storage core claimrule add`

• `esxcli storage hpp device set`

• `esxcli storage core claimrule list`

• `esxcli storage hpp device list`

A Pure Storage FlashArray is configured with NVMe-oF. The administrator wants to set the latency evaluation time to 3 minutes for their devices. Which parameter should they specify in their command?

• `-S 180000`

• `-T 180000`

• `-P LB-Latency`

• `-d eui.003b7b308d98f94224a9375e0001903a`

An administrator needs to add a claim rule for all new NVMe devices from Pure Storage. What is the correct command syntax they should use?

• `esxcli storage core claimrule add --rule 102 -t vendor -P HPP -V NVMe -M "Pure*"`

• `esxcli storage core claimrule add --rule 102 -t vendor -P HPP -V "Pure*" -M NVMe`

• `esxcli storage core claimrule add --rule 102 -t vendor -V NVMe -M "Pure*"`

• `esxcli storage core claimrule add --rule 102 -t vendor -P HPP -M "Pure*" -V NVMe`

A storage administrator is tasked with configuring multipathing for NVMe devices. They want to ensure that the configuration is saved and applied upon reboot. What type of configuration should they use?

• Runtime

• File

• Temporary

• Persistent

When configuring multipathing for NVMe-oF, which of the following is NOT a characteristic of the High Performance Plugin (HPP)?

• It supports latency-based path selection.

• It requires Native Multipathing Plugin (NMP) for configuration.

• It is designed for higher-speed protocols.

• It manages paths for NVMe devices.

An administrator notices that their NVMe-oF datastore is configured with the default path selection policy. They want to switch to a load balancing method based on latency. What command would they execute?

• `esxcli storage hpp device set -d -P LB-RR`

• `esxcli storage hpp device set -d -P LB-Latency`

• `esxcli storage core claimrule add --rule 101 -t vendor -P HPP`

• `esxcli storage core claimrule load`

A company is experiencing intermittent connectivity issues with their NVMe-oF storage. They decide to implement a multipathing configuration. What is the primary benefit of using multipathing in this context?

• Increased storage capacity

• Improved data redundancy

• More reliable connections to datastores

• Simplified management of storage devices

An administrator is configuring a new NVMe-oF datastore and needs to monitor the latency of paths. What is the recommended polling interval to evaluate latency?

• 30 seconds

• 3 minutes

• 5 minutes

• 1 minute
