Question # 2 A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.) A. Connect host and storage ports to the same switches.B. Decrease the default queue depth on the host to eight.C. Zone the host by using the host WWPNs.D. Configure Jumbo frames In the entire data path.
Click for Answer
A. Connect host and storage ports to the same switches.D. Configure Jumbo frames In the entire data path.
Answer Description Explanation:
To ensure the best performance in an iSCSI SAN implementation:
Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.
Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance. Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal performance.

Question # 3 A technician is troubleshooting a user’s PC that is displaying pop-up windows, which are advertising free software downloads. When the technician tries to open a document, the system displays an error message that reads: Not enough memory to perform this operation. Which of the following should be the technician's next step to resolve this issue? A. Install antispywareB. Reimage the systemC. Disable the pop-up blockerD. Upgrade the browserE. Install antivirus software
Click for Answer
A. Install antispyware
Answer Description Explanation:
The presence of pop-up windows advertising free software and the error message about memory are indicative of spyware infection. Installing and running antispyware software is a practical first step to remove the unwanted software and resolve the issue without resorting to more drastic measures like re-imaging the system.
Question # 4 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 # 5 An administrator has a NetApp AFF cluster supporting an application with twelve LUNs allocated across four volumes. There is a requirement to configure a Snapshot copy of all LUNs simultaneously as a single unit.

Question # 6 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.

NetApp Community Discussion on Snapshot Deletion
Question # 7 An engineer Is implementing a data migration scenario for a customer who has multiple FC LUNs across multiple third-party SAN arrays. The engineer wants to use Foreign LUN Import (FLI) for the migration.
What is a requirement on the destination NetApp ONTAP cluster for FLI? A. A valid SnapMirror licenseB. At least one FC port in initiator modeC. A valid NetApp XCP licenseD. At least one FC port in target mode
Click for Answer
D. At least one FC port in target mode
Question # 8 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.
