D-PWF-OE-00 Exam Dumps - EMC Converged Infrastructure Questions and Answers

While "alerting" is a broad topic, in the context of security:

Notify administrators of potential security issues (Option B): The alerting system is designed to trigger notifications for security-relevant events. Examples include:

Failed Login Attempts: Repeated failures which might indicate a brute-force attack.

Unauthorized Access: Connections from unapproved IPs (if restrictions are set).

Certificate Expiry: Warning that SSL/TLS certificates are about to expire, which would break secure management connections.

Encryption Failures: Alerts if a SED drive is unlocked or CloudLink key retrieval fails.

Configuring PowerFlex File (NAS) involves creating the logical file system and then defining how clients access it.

Create the shared file system using the GUI (Option A): The administrator uses the PowerFlex Manager (or Block UI) to define the file system properties, such as name, size, and the Storage Pool it will consume capacity from.

Configure multi-node access permissions (Option C): Once the file system exists, it is not accessible until it is "Exported" (NFS) or "Shared" (SMB). During this step, the administrator must configure the access control lists (ACLs) or export policies that define which client IPs or Subnets (nodes) are allowed to mount the file system and whether they have Read-Only or Read-Write permissions.

In PowerFlex terminology, the Storage Data Server (SDS) acts as the "Target" for I/O operations.

Organize drives for storage pools (Option B): The SDS takes ownership of the local physical drives (NVMe/SSD/HDD) installed in the server. It aggregates these drives and contributes them to the Storage Pool. It handles the reading and writing of data blocks to this physical media.

Incorrect Options: Metadata is managed by the MDM (A). Access to external resources (C) is not the function of the SDS (which provides internal storage). Deduplication (D) is a specific feature, not the primary function of the component.

Creating a Storage Pool is a foundational step in configuring PowerFlex, as it defines the physical capacity available for volume creation.

Define the Protection Domain (Option B): PowerFlex utilizes a strict hierarchy. Top Level $\rightarrow$ Protection Domain (PD) $\rightarrow$ Storage Pool (SP). You cannot create a Storage Pool without first identifying which Protection Domain it resides in. The Protection Domain groups a specific set of SDS (Storage Data Server) nodes. The Storage Pool creates a logical subset of drives within those nodes.

Assign drives with consistent performance metrics (Option D): This is a critical best practice and requirement. PowerFlex distributes data chunks (mesh mirroring) across all drives in a Storage Pool. If you mix NVMe SSDs with slow SATA HDDs in the same pool, the performance of the entire pool will drop to the speed of the slowest drive (the "straggler" effect). Therefore, a Storage Pool must consist of homogeneous media types (e.g., all SAS SSDs or all NVMe) to ensure predictable and consistent IOPS and latency.
