NEW QUESTION # 86
What is the Backup Data packet flow from the NetWorker Client to the PowerProtect DD appliance?
- A. Through the Backup Server and then to PowerProtect DD
- B. Through the Media Server and then to PowerProtect DD
- C. Through the Storage Node and then to PowerProtect DD
- D. Direct from the SAN Media Server to PowerProtect DD
Answer: D
Explanation:
In a typical NetWorker backup architecture, the data flow starts at the NetWorker Client, which sends backup data to the Media Server. The Media Server is responsible for processing the data and then forwarding it to the PowerProtect DD appliance for storage. This flow allows for efficient data handling, including deduplication and compression before the data reaches the PowerProtect DD system.

What is the correct sequence to configure and enable Cloud Tier on a PowerProtect DD system?
Answer:
Explanation:
Explanation:
Disable Filesystem: This step ensures that any current filesystem operations are halted to safely modify the configuration.
Add Available Storage: This involves allocating additional storage resources for the Cloud Tier functionality.
Enable Filesystem: After adding storage, the filesystem needs to be re-enabled to make the system operational again.
Configure Cloud Tier: Set up the necessary parameters and options for the Cloud Tier, specifying how it will interact with the cloud storage.
Enable Cloud Tier: Finally, this step activates the Cloud Tier, allowing data to be tiered to cloud storage according to the configured settings.

Answer: A
NEW QUESTION # 94
Refer to the exhibit.
To which shelf and port should SAS HBA slot 1 port B be connected?
- A. Shelf 04 BH
- B. Shelf 01 BE
- C. Shelf 04 BE
- D. Shelf 01 BH
Answer: C
Explanation:
Based on the configuration:
SAS HBA Slot 1 has ports labeled A and B.
The connection sequence suggests that:
Shelf 01 is the first shelf connected, and it has ports BE and BH.
Shelf 02 through Shelf 04 continues the pattern with their respective ports.
Given the layout:
SAS HBA Slot 1 Port B should be connected to Shelf 01 BH to maintain proper connectivity according to the configuration flow.
NEW QUESTION # 95

What is the correct sequence of operations used by the PowerProtect DD DIA in the end-to-end verification process?
Answer:
Explanation:
Explanation:
A screenshot of a computer Description automatically generated
1. Writes request from the backup software
First, the backup software sends a write request to the DD system.
2. Analyzes data for redundancy and stores new data segments
Next, DDOS analyzes the incoming data for redundancy and stores only the unique data segments to optimize storage.
3. Stores the fingerprints
After deduplication, the system stores the unique fingerprints of the data.
4. Verifies that the checksum that is read back matches the checksum that is written to the disk This step involves verifying the data integrity by matching the written checksum with the read checksum.
5. Verifies that DDOS can read data from the disk
Finally, the system verifies that the data can be read back correctly from the disk, ensuring the write was successful.

NEW QUESTION # 104
A customer needs to adjust the PowerProtect DD authentication. Which three methods are available in the DD System Manager? (Select 3)
- A. PAP
- B. AD
- C. NIS
- D. RADIUS
- E. SSO
- F. OAuth
Answer: B,D,E
Explanation:
In the DD System Manager of PowerProtect DD, authentication methods available for configuration include RADIUS, Active Directory (AD), and Single Sign-On (SSO). Here's a breakdown of each method:
* RADIUS: Remote Authentication Dial-In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for users. It enables secure user authentication across the network, especially useful for managing access in large environments.
* Active Directory (AD): Integrating with AD allows administrators to manage user access through Microsoft's directory service, leveraging existing credentials and policies. This is beneficial for organizations with established AD environments as it provides seamless integration and centralized management.
* Single Sign-On (SSO): SSO allows users to authenticate once and gain access to multiple applications or systems without being prompted to log in again. This is particularly useful in environments where users need frequent access to different resources, reducing the need for repeated logins and enhancing user convenience.
