QUESTION: 21

An administrator has two Kubernetes clusters: one uses GKE, and the other uses AKS. The administrator wants to migrate from Google to Azure. The migration must be application aware and move all components and data for the application.
Which product should the administrator use?

BlueXP Copy and Sync
SnapMirror
Astra Control Service
Cloud Backup Service

Answer(s): C

Explanation:

For migrating applications between Kubernetes clusters--specifically from Google Kubernetes Engine (GKE) to Azure Kubernetes Service (AKS)--and ensuring that all components and data are moved in an application-aware manner, the best product to use is Astra Control Service. Here's why:
Application-Aware Migration: Astra Control Service is designed to manage, protect, and move applications in Kubernetes environments. It understands the structure of Kubernetes applications and can manage the entire lifecycle, including migration of application data along with its configuration and state.
Cross-Platform Capability: Astra Control Service supports multiple Kubernetes platforms, making it suitable for migrations from GKE to AKS. It ensures that all parts of the Kubernetes application, including persistent volumes and configurations, are consistently replicated to the new environment. Seamless Migration Process: The service automates much of the migration process, reducing the complexity and potential for error when moving applications between different cloud providers or Kubernetes services.
For more detailed guidance on using Astra Control Service for Kubernetes migrations, refer to the NetApp documentation: NetApp Astra Control Service Documentation.

QUESTION: 22

An administrator needs to move several volumes that contain iSCSI LUNs from an ONTAP AFF cluster to CVO.
Which method should be used?

SnapMirror
XCP
Foreign LUN Import (FLI)
CloudSync

Answer(s): A

Explanation:

To move several volumes containing iSCSI LUNs from an ONTAP AFF cluster to Cloud Volumes ONTAP (CVO), the most appropriate method is using SnapMirror. Here's the process:
Utilizing SnapMirror for LUN Migration: SnapMirror is NetApp's replication technology that is ideally suited for efficiently transferring data between ONTAP systems, including from AFF to CVO. It is capable of handling complex data structures like iSCSI LUNs, ensuring data integrity and consistency during the transfer.
Configuration of SnapMirror: Set up a SnapMirror relationship between the source AFF cluster and the destination CVO instance. This involves configuring the SnapMirror policy, scheduling the replication, and initializing the transfer of data.
Advantages for iSCSI LUNs: SnapMirror maintains the layout and attributes of the iSCSI LUNs during replication, which is crucial for ensuring that the storage is ready for immediate use upon completion of the replication to the CVO environment.
For step-by-step instructions on configuring and using SnapMirror for transferring iSCSI LUNs, consult the NetApp documentation on SnapMirror: NetApp SnapMirror Documentation.

QUESTION: 23

ONTAP's Autonomous Anti-ransomware engine reports a potential ransomware attack. The administrator finds the majority of the files appear encrypted and disables the share.
What should the administrator do to minimize data loss?

Create a FlexClone using the locked snapshot and re-enable the share
Perform a SnapRestore using the weekly snapshot and re-enable the share
Rehost the volume to a different SVM and create a new share
Take a manual snapshot and re-enable the share

Answer(s): 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.
For more details on using SnapRestore in ONTAP systems, refer to the NetApp documentation on data protection and recovery: NetApp SnapRestore Documentation.

QUESTION: 24

An outbound Internet connection is not available to send AutoSupport messages. BlueXP has automatically configured the Cloud Volumes ONTAP systems to use the Connector as a proxy server. The Connector requires an inbound connection on port 3128.
What must the administrator do?

Add the Internet gateway IP to the allow list
Modify the associated security group
Modify the policy on the cluster-mgmt LIF
Configure BlueXP with an external IP address

Answer(s): B

Explanation:

When BlueXP has configured Cloud Volumes ONTAP systems to use the Connector as a proxy server, and the Connector requires an inbound connection on port 3128, the necessary action is to modify the associated security group. Here's what to do:
Identify Security Group: Determine which security group is associated with the Cloud Volumes ONTAP or the Connector instance.
Modify Security Group Rules: Update the security group rules to allow inbound traffic on port 3128. This is crucial to enable the Connector to receive connections as a proxy server for sending AutoSupport messages.
Apply and Verify Changes: After updating the security group, apply the changes and verify that the Connector can successfully transmit AutoSupport messages through the specified port. For guidance on configuring security groups in AWS, consult the AWS documentation or the specific guidelines provided by your cloud provider: AWS Security Groups Documentation.
