2. 1.What are two characteristics of a SnapVX Linked Target? A. They are read writable (R/W). B. They support a maximum of 1024 snaps per volume B. They cannot send data to SRDF C. They can be made secure Answer: AC Explanation: Step by Step Comprehensive Detailed SnapVX Linked Targets: SnapVX is a snapshot technology used in Dell PowerMax storage arrays. A linked target is a volume that provides read/write access to a specific point-in-time copy (snapshot) of a source volume. Read/Write Access: Unlike traditional snapshots, which are typically read-only, SnapVX linked targets allow modifications. This makes them suitable for use cases like testing, development, and data analysis where changes need to be made to a copy of the data without affecting the original source. Secure Snapshots: SnapVX offers the capability to create "secure snapshots." These snapshots are write-protected and prevent any modifications or deletion, ensuring data integrity and protection against accidental or malicious changes. Why other options are incorrect: B. They support a maximum of 1024 snaps per volume: This is partially correct. While a source volume can have up to 1024 snapshots, this limit includes all types of snapshots (manual, automated, and legacy), not just linked targets. B. They cannot send data to SRDF: This is incorrect. SnapVX linked targets can participate in SRDF (Symmetrix Remote Data Facility) replication, allowing for disaster recovery and data mobility.

4. Answer: Explanation: Set up the migration environment to migrate applications from the source array to the target array. Examine the specific storage for the applications on the source array and automatically provision 4 / 9

5. equivalent storage on the target array. Initiate data synchronization from the source to the target and cutover to make source array paths inactive so target array services all host I/O. Commit the necessary changes after the source to target data synchronization is complete and all application data has been migrated to the target. Remove the configured array-to-array connectivity for the data migration pathway on both storage arrays. Correct Order: Set up the migration environment to migrate applications from the source array to the target array. Why: This is the initial setup phase, where you configure the necessary settings on both the source and target arrays to enable the migration. This involves actions like: Verifying compatibility between the source and target arrays. Ensuring that the required licenses are in place (e.g., NDM license). Configuring network connectivity (FC or iSCSI) for data transfer between the arrays. Examine the specific storage for the applications on the source array and automatically provision equivalent storage on the target array. Why: Before migrating data, you need to ensure that the target array has the appropriate storage capacity and configuration to host the applications. How: NDM can often automatically provision equivalent storage on the target based on the source configuration. This includes creating storage groups, volumes, and masking views that mirror the source. Initiate data synchronization from the source to the target and cutover to make source array paths inactive so target array services all host I/O. Why: This is the core of the migration process. Data is copied from the source to the target while the application continues to run. Cutover is the final step where I/O is redirected to the target array. How: Synchronization: Data is copied in the background. Cutover: Once synchronization is complete, a brief cutover is performed. In a well-planned NDM, this cutover is designed to be within the I/O timeout limits of most applications. Commit the necessary changes after the source to target data synchronization is complete and all application data has been migrated to the target. Why: This step finalizes the migration and makes it permanent. What it involves: The migration session is acknowledged and the configuration is finalized on the target array. Remove the configured array-to-array connectivity for the data migration pathway on both storage arrays. Why: After the migration is complete, the temporary connections used for data transfer between the arrays should be removed to free up resources and maintain a clean configuration. What it involves: This typically means removing the FC zones or iSCSI settings that were configured specifically for the NDM process. 4.What are two characteristics of a SnapVX Clone? A. Maximum 1024 snaps per volume B. Can be made secure C. Restores directly to the source volume D. Is Read-only 5 / 9

6. E. Can be made crash consistent Answer: BE Explanation: Step by Step Comprehensive Detailed SnapVX Clones: SnapVX clones are full, writable copies of a source volume created using the SnapVX snapshot technology. They are independent volumes that can be used for various purposes, such as testing, development, or data analysis. Secure Snapshots: SnapVX offers the capability to create "secure snapshots." When a clone is derived from a secure snapshot, it inherits the same protection, making it immutable and preventing any modifications or deletion. This ensures data integrity and protection against accidental or malicious changes. Crash Consistent: SnapVX clones can be made crash consistent. This means that the clone captures a point-in-time copy of the source volume that is consistent with a database or application crash. This is important for ensuring data integrity and recoverability in situations where the source volume experiences an unexpected outage. Why other options are incorrect: A. Maximum 1024 snaps per volume: This limit applies to the source volume, not the clones themselves. Each clone is an independent volume. C. Restores directly to the source volume: Clones are independent copies and do not directly restore to the source volume. Data can be copied or moved from the clone to the source if needed. D. Is Read-only: SnapVX clones are fully writable copies, not read-only. Reference and documents of Dell's public documentation for PowerMax Operate v.2: Dell Solutions Enabler 10.0.0 TimeFinder SnapVX CLI User Guide: This guide provides detailed information about SnapVX features and commands, including how to create and manage clones. It confirms the ability to create secure clones and the option to make them crash consistent.
