Which network service is required?
- A . SMTP
- B . Kerberos
- C . HTTPS
- D . SMB
Correct Answer: C
C
Explanation:
In the scenario where an administrator is using BlueXP Copy and Sync to move an NFS dataset and the Data Broker shows the status "Unknown" despite confirmed NFS connectivity, the required network service is HTTPS.
Here’s why:
HTTPS for Data Broker Communication: The Data Broker, which orchestrates data movement in BlueXP Copy and Sync, uses HTTPS to communicate securely with both the source and destination systems, as well as with NetApp’s cloud services. This secure communication channel is essential for managing the data transfer processes reliably and securely.
Verifying HTTPS Connectivity: Ensure that all network components, such as firewalls and routers, are configured to allow HTTPS traffic (port 443) from the Data Broker to the NFS endpoints and back. This includes checking for any blocked ports or filtered traffic that could impede the Data Broker’s operation.
Troubleshooting Network Issues: If the status remains "Unknown," further network diagnostics may be necessary to identify any disruptions or misconfigurations in HTTPS connectivity that could affect the Data Broker’s functionality.

What should the administrator do to minimize data loss?
- A . Create a FlexClone using the locked snapshot and re-enable the share
- B . Perform a SnapRestore using the weekly snapshot and re-enable the share
- C . Rehost the volume to a different SVM and create a new share
- D . Take a manual snapshot and re-enable the share
Correct Answer: B
B
Explanation:
When dealing with a potential ransomware attack where files appear encrypted, it is crucial to restore the affected data to a point before the corruption occurred. The best course of action in this scenario is to perform a SnapRestore using a known good weekly snapshot and then re-enable the share. Here’s how:
Assess the Snapshots: Verify that you have snapshots that predate the ransomware attack. These snapshots should be intact and free from encryption or corruption.
Perform a SnapRestore: Use the SnapRestore operation to quickly revert the entire volume to the state captured in the selected weekly snapshot. SnapRestore is efficient because it does not involve data movement; it simply reverts pointers in the filesystem.
Re-enable the Share: After successfully reverting the volume to a good state, the share can be safely re-enabled, allowing users to access the clean, restored data.
Verify System Integrity and Security: Before re-enabling the share, ensure that all system vulnerabilities are addressed to prevent future attacks. Implement improved security measures as needed.
