Question No. 1

A healthcare customer wants to Implement an FC SAN solution consisting of a NetApp ONTAP system, Broadcom switches, and servers.

Which tool contains detailed blueprints and implementation references that can be used to design this solution?

Show Answer Hide Answer
Correct Answer: B

The correct tool for designing an FC SAN solution consisting of a NetApp ONTAP system, Broadcom switches, and servers is the 'NetApp Verified Architecture' (NVA). The NetApp Verified Architecture provides comprehensive blueprints and detailed implementation references. These blueprints are thoroughly tested, prescriptive in nature, and designed to minimize deployment risks and accelerate time to market. They are specifically designed to help ensure that the architecture meets the high standards required for enterprise environments.

NVA documents include design guides, best practices, and detailed configuration steps, making them invaluable for planning and deploying complex solutions like the one described.

For more information, you can refer to the official NetApp documentation on NetApp Verified Architectures:

These resources provide detailed insights into the architecture, including technology requirements, deployment procedures, and additional references for further reading.


Question No. 2

An administrator is configuring ISCSI on an SVM and requires that all network traffic Is encrypted. What must be done to satisfy this requirement?

Show Answer Hide Answer
Correct Answer: B

To ensure that all network traffic is encrypted for iSCSI on an SVM, configuring IPsec is required. IPsec (Internet Protocol Security) provides end-to-end encryption for IP traffic, ensuring that data transmitted over the network is secure.

NetApp Documentation on Configuring IPsec


Question No. 3

When using FCP, what is the minimum number of FC switches needed to redundantly attach three ESXi hosts?

Show Answer Hide Answer
Correct Answer: C

When using Fibre Channel Protocol (FCP), the minimum number of FC switches needed to redundantly attach three ESXi hosts is 2. This setup ensures that each host has multiple paths to the storage, providing high availability and fault tolerance. Each ESXi host should be connected to both switches, allowing for continuous operation even if one switch fails.

Question No. 4

After deleting a LUN, an administrator notices that the space does not show as available. What needs to be done to reclaim the space?

Show Answer Hide Answer
Correct Answer: D

After deleting a LUN, if the space does not show as available, performing space reclamation is necessary. Space reclamation involves identifying and reclaiming unused space on the storage system, making it available for new data. This process ensures that the deleted LUN's space is properly freed up and reflected in the available storage capacity.

Question No. 5

An administrator creates a new volume and a LUN for an SAN-connected application that uses snapshots. The application has fast-growing data that is constantly being populated and deleted afterwards.

Which option can be set to manage the space automatically?

Show Answer Hide Answer
Correct Answer: A

To manage space automatically for a volume containing a LUN with fast-growing data, enabling automatic resizing on the volume is recommended. This feature allows the volume to grow dynamically as needed, accommodating the fluctuating data size without manual intervention. This helps in managing storage efficiently and ensures that the application has the required space.
