What is required to use external antivirus protection in NetApp ONTAP software?
Answer(s): D
External antivirus protection in ONTAP (Vscan) requires a scanner pool, which defines the external antivirus servers that perform file scanning on behalf of the cluster. Without a scanner pool, ONTAP cannot offload scan requests to external antivirus engines.
An administrator has presented a thin-provisioned iSCSI LUN to your ESXi host. The administrator deleted data from the datastore in ESXi. No blocks have been freed on the LUN.Which two steps would you use to solve this problem? (Choose two.)
Answer(s): A,C
Enabling space allocation allows ONTAP to receive SCSI UNMAP commands from the host so freed blocks can be reclaimed on the LUN. Using the VMFS unmap command triggers the ESXi host to send those UNMAP commands, returning unused space to the storage system.
Which NetApp ONTAP component enables clients to access data while using duplicate IP addresses?
IPspaces provide separate network routing tables within ONTAP, allowing identical or overlapping IP address ranges to be used simultaneously. This enables client access to data even when duplicate IP addresses exist.
Which NetApp administration utility provides installation, management, and mediator services for NetApp ONTAP Select?
ONTAP Select Deploy is the administration utility used to install, manage, and monitor ONTAP Select clusters and also provides the mediator service required for high availability operations.
Which NetApp ONTAP command reports the average delay that each ONTAP subsystem contributes to I/O response times?
Answer(s): B
The statistics system show command reports I/O latency broken down by ONTAP subsystems, such as network, WAFL, and disk, allowing administrators to see the average delay each subsystem contributes to overall I/O response time.
Which NetApp tool can pull performance metrics from NetApp ONTAP software and forward the metrics to display on Grafana dashboards?
NetApp Harvest collects performance and capacity metrics from ONTAP systems and exports them in formats compatible with time-series databases, enabling the data to be visualized directly in Grafana dashboards.
Which component on the Vscan server is responsible for communication between the system running NetApp ONTAP software and the Vscan server?
The Antivirus Connector runs on the Vscan server and handles communication between ONTAP and the external antivirus engine, receiving scan requests from ONTAP and returning scan results.
An administrator creates a new FlexCache volume and wants to warm the cache before the client's initial access.How is this task accomplished?
Answer(s): A
FlexCache supports prepopulation, which proactively reads data from the origin volume into the cache. This warms the cache so data is already available locally before any client access occurs, reducing initial access latency.
