Question # 1 Which of the following environmental effects can be the result of using virtualization? A. Greater energy consumptionB. Noise pollutionC. Reduced space requirementsD. Fewer maintenance needs
Click for Answer
C. Reduced space requirements
Answer Description Explanation:
One of the key environmental benefits of using virtualization is the reduction in physical space requirements. Virtualization allows multiple virtual machines to run on a single physical server, reducing the need for multiple physical servers. This consolidation leads to fewer physical machines, saving space in data centers and reducing the overall physical footprint.
A. Greater energy consumption is incorrect as virtualization typically leads to reduced energy consumption due to the consolidation of hardware.
B. Noise pollution can be reduced because fewer physical machines often mean less overall noise.
D. Fewer maintenance needs is a possible benefit but not directly related to environmental effects like reduced space requirements.

Question # 2 A user reports receiving constant, unwanted pop-ups and being unable to close the browser window. These issues have impacted the user's productivity and may have caused the user's files to be altered. Which of the following should a technician do to address these issues with minimal impact to the user? A. Use System Restore to recover the OS files.B. Wipe the computer and install a new copy of the OS.C. Identify whether the disk partition table has been reduced in size.D. Perform a full-system, antivirus scan and check browser notifications.
Click for Answer
D. Perform a full-system, antivirus scan and check browser notifications.
Answer Description Explanation:
For issues related to constant, unwanted pop-ups and browser window problems, a careful approach that minimizes impact to the user's data and productivity is advisable:
Perform a full-system, antivirus scan: This step involves using antivirus software to scan the entire system for malware or adware that might be causing the pop-ups and browser issues.
Check browser notifications: Some unwanted pop-ups may result from browser notification permissions inadvertently granted to malicious or spammy websites. Reviewing and adjusting these settings can help stop the pop-ups.
Question # 3 During an iSCSI deployment, the customer requests a change of front-end network connections on the NetApp ONTAP cluster from twinax cables to fiber-optic cables.
Which two NetApp tools would an administrator use to verify the supported port speeds and transceivers? (Choose two.) A. Hardware Universe to determine supported transceiversB. Interoperability Matrix Tool to determine supported transceiversC. Hardware Universe to determine supported port speedsD. Interoperability Matrix Tool to determine supported port speeds
Click for Answer
A. Hardware Universe to determine supported transceiversB. Interoperability Matrix Tool to determine supported transceivers
Answer Description Explanation:
During an iSCSI deployment, if a customer requests a change from twinax cables to fiber-optic cables, two NetApp tools can be used to verify the supported port speeds and transceivers:
Hardware Universe (HWU): This tool is essential for determining the supported transceivers and port speeds for NetApp hardware. It provides detailed information on hardware compatibility, including supported transceivers, cables, and port speeds, which helps ensure that the selected components are compatible with the NetApp storage system.
Interoperability Matrix Tool (IMT): The IMT provides comprehensive compatibility information between NetApp products and third-party components. It includes details on supported transceivers and port speeds, ensuring that any changes made to the network connections are supported and will function correctly in the given configuration.
For more detailed information, you can refer to the following resources:
NetApp Hardware Universe (NetApp).
NetApp Interoperability Matrix Tool (NetApp).

Question # 7 On a two-node NetApp AFF ASA cluster, what is the recommended minimum number of paths for a SAN environment from the client host perspective? A. 2B. 8C. 4D. 16
Click for Answer
C. 4
Answer Description Explanation:
In a two-node NetApp AFF ASA cluster, the recommended minimum number of paths for a SAN environment from the client host perspective is 4. This configuration ensures high availability and load balancing, which are critical for maintaining performance and resilience in a SAN environment. Each host should have at least two paths to each controller to achieve this setup.

Question # 8 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. Snapshot autodeleteB. Aggregate overcommittedC. Volume thinly provisionedD. Autonomous Ransomware Protection
Click for Answer
A. Snapshot autodelete
Answer Description 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.
