NEW QUESTION # 35
Which security algorithms are used for MSDP in NetBackup?
- A. AES 256 bit CTR encryption and SHA256 fingerprinting
- B. AES encryption and MD5 fingerprinting
- C. Blowfish encryption and MD5 fingerprinting
- D. AES 128 bit encryption and SHA-2 fingerprinting
Answer: A
Explanation:
The correct answer is AES 256 bit CTR encryption and SHA256/SHA-2 fingerprinting. In NetBackup, MSDP stands for Media Server Deduplication Pool, and its security model protects deduplicated data using modern encryption and fingerprinting algorithms. Cohesity NetBackup documentation identifies the MSDP data-at- rest cipher as AES-256-CTR, specifically listing "MSDP: AES-256-CTR" under NetBackup data-at-rest encryption ciphers. For fingerprinting, Cohesity documents that NetBackup 8.1 introduced a more secure MSDP fingerprint algorithm where the SHA-2 algorithm replaces the existing MD5-like algorithm. The upgrade documentation further explains that rolling MSDP data conversion converts older containers to the AES encryption and SHA-2 fingerprint algorithm, confirming that Blowfish and MD5-like fingerprints are legacy mechanisms rather than the current MSDP security standard. Therefore, option A is the only choice that combines the correct MSDP encryption mode, AES-256-CTR, with the correct secure fingerprinting family, represented in the option as SHA256 fingerprinting. References/topics: NetBackup Security and Encryption Guide, Ciphers used in NetBackup, MSDP fingerprinting algorithm changes, and MSDP rolling data conversion.

Which Role-Based Access Control permissions does a user need to have in order to add an asset to a Protection Plan?
- A. View and Update
- B. View and Subscribe
- C. View and Manage
- D. View and Create
Answer: B
Explanation:
The correct permissions are View and Subscribe. In NetBackup RBAC, adding an asset to a Protection Plan is treated as subscribing the asset to that plan, not creating, updating, or managing the plan itself. Cohesity documentation describes the workflow as selecting one or more assets, clicking Add protection, choosing a protection plan, and clicking Protect; it also states that a single asset or group of assets can be subscribed to one or more protection plans. The RBAC permissions model separates plan administration from asset subscription. The role-permissions topic defines protection plans as the area used to manage how backups are performed with protection plans, while assets are managed separately under the Assets permission category.
Official NetBackup RBAC guidance states that to add assets to a protection plan, the user requires View and Subscribe permissions on the protection plan, with corresponding asset permissions to view and protect the assets. Therefore, View and Subscribe is the permission pair directly aligned with adding an asset to a Protection Plan. References/topics: RBAC role permissions, Protection Plans, Subscribe an asset or asset group, and Workload asset protection workflow.
