Network Appliance Implementation Engineer - SAN ONTAP Exam Sample Questions (Q64-Q69):

NEW QUESTION # 64
What Is the storage construct that enables an NVMe client to store data in an SVM?

A. LUN
B. Subsystem
C. FlexGroup volume
D. Namespace

Answer: B

Explanation:
In an NVMe environment, the storage construct that enables an NVMe client to store data in an SVM (Storage Virtual Machine) is aSubsystem. A subsystem is a collection of one or more namespaces, which are used to store data. This abstraction allows for efficient management and scaling of NVMe storage within the ONTAP environment.
For further information, refer to:
* NetApp NVMe/FC Configuration (NetApp).

NEW QUESTION # 65
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?

A. Enable space reservation on the LUN.
B. Unmap the LUN.
C. Disable volume snapshot autodelete.
D. Enable automatic resizing on the volume.

Answer: D

Explanation:
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.
For further details, refer to:
* NetApp Documentation on Volume Management
* NetApp Community Discussion on Automatic Resizing

NEW QUESTION # 66
What are two benefits of implementing VLANs for NVMe/TCP configurations? (Choose two.)

A. Increased resiliency
B. Increased security
C. Reduced number of IPspaces
D. Reduced number of broadcast domains

Answer: A,B

Explanation:
Implementing VLANs for NVMe/TCP configurations provides several benefits, two of which are increased resiliency and increased security:
* Increased Resiliency: VLANs help segment the network traffic, reducing the risk of a single point of failure. By isolating NVMe/TCP traffic into specific VLANs, network issues can be contained within a VLAN, preventing them from affecting other parts of the network. This isolation ensures that disruptions are minimized and network resiliency is enhanced.
* Increased Security: VLANs provide an added layer of security by segregating traffic. This segregation ensures that NVMe/TCP traffic is isolated from other types of traffic, reducing the risk of unauthorized access or data breaches. VLANs help in enforcing stricter access controls and monitoring, thereby increasing the overall security of the network.
For more information on the benefits of VLANs in NVMe/TCP configurations, you can refer to NetApp's technical resources:
* Implementing and Configuring Modern SANs with NVMe-oF (NetApp).
* SAN Configuration Best Practices (NetApp Community).

NEW QUESTION # 67
A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.
What could cause this behavior?

A. Volume thinly provisioned
B. Autonomous Ransomware Protection
C. Aggregate overcommitted
D. Snapshot autodelete

Answer: D

Explanation:
The likely cause for the disappearance of all snapshots after a ransomware attack that encrypted all files on the LUN is the Snapshot autodelete feature. When the volume becomes full due to the encryption, the autodelete feature removes older snapshots to free up space, preventing the volume from running out of space and ensuring write operations can continue.
For more information, see:
* NetApp Documentation on Snapshot Autodelete
* NetApp Community Discussion on Snapshot Deletion

NEW QUESTION # 68
When using FCP, what is the minimum number of FC switches needed to redundantly attach three ESXi hosts?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
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.
For more information, refer to:
* NetApp Documentation on FC Switch Configurations
* NetApp Community Discussion on Redundant FC Setup
