Dell EMC D-PE-OE-23 Exam Questions - Navigate Your Path to Success

Correct : C

Understanding iDRAC Group Management and Compatibility

Server Management and Configuration Tools (14%)

Define the function of the iDRAC, login procedures, licensing, and connection methods

Explain the management interface options - LCC, racadm, OMSA, iSM, OME

System Administration (18%)

Configure BIOS, Storage, virtual media, networking, user access, lockdown mode, and group management

Scenario Analysis

The customer has acquired six Dell PowerEdge R750 servers and wants to add them to an existing iDRAC Group that currently contains R760 servers. However, they are encountering errors during this process.

Understanding Dell Server Generations

PowerEdge R750: Part of the 15th Generation (15G) servers.

PowerEdge R760: Part of the 16th Generation (16G) servers.

iDRAC Group Manager Limitations

iDRAC Group Manager allows administrators to manage multiple servers from a single interface.

Important Limitation: Servers of different generations cannot be grouped together in iDRAC Group Manager.

This is due to differences in firmware, hardware capabilities, and iDRAC features between server generations.

Impact: Attempting to add 15G servers (R750) to a group containing 16G servers (R760) will result in errors.

Evaluation of Options

Option A: R750 iDRACs firmware is out of date

Analysis: While outdated firmware can cause issues, it is not the primary reason here. Firmware updates would not resolve the incompatibility between different server generations.

Option B: R750 iDRACs are not running the same version of firmware

Analysis: Similar to Option A, firmware version mismatches can cause problems but not errors related to grouping different generations.

Option C: 15G and 16G servers cannot be in the same group

Correct Answe r: This is the primary reason for the errors encountered.

Option D: The feature requires iDRAC Enterprise

Analysis: Since the customer already has an existing iDRAC group with R760 servers, they likely have the necessary licensing.

Dell Operate Reference

Server Management and Configuration Tools (14%)

Emphasizes understanding iDRAC functionalities and limitations.

System Administration (18%)

Highlights the importance of group management and its constraints.

Conclusion

The errors occur because iDRAC Group Manager does not support grouping servers from different generations. The customer cannot add 15G servers (R750) to a group that contains 16G servers (R760).

Correct : A

Understanding Easy Restore Functionality

Server Troubleshooting (32%)

Explain Easy Restore, diagnostic utilities, and hardware diagnostic options

What is Easy Restore?

Easy Restore is a feature in Dell PowerEdge servers that automatically restores system-specific information after a system board replacement.

Purpose: Minimizes downtime and simplifies recovery by retaining critical system identity information.

Data Restored by Easy Restore

Service Tag: The unique identifier (serial number) of the server.

System Configuration Settings: Includes BIOS settings and other non-volatile configurations.

Data NOT Restored by Easy Restore

Option B: HBA Configuration

Host Bus Adapter settings are not restored automatically.

Option C: PERC Configuration

RAID configurations need to be backed up and restored separately.

Option D: Lifecycle Controller Log

Logs are stored on the system board and do not transfer after replacement.

Evaluation of Options

Option A: Service Tag

Correct Answe r: Easy Restore recovers the Service Tag, preserving the server's identity.

Option B: HBA Configuration

Analysis: Requires manual configuration or restoration from a backup.

Option C: PERC Configuration

Analysis: RAID settings are critical but need separate backup and restoration procedures.

Option D: Lifecycle Controller Log

Analysis: Logs are not preserved after system board replacement.

Dell Operate Reference

Server Troubleshooting (32%)

Highlights the importance of understanding what Easy Restore can and cannot recover.

Conclusion

After replacing the system board on a Dell PowerEdge 16G server, Easy Restore will recover the Service Tag, ensuring the server maintains its unique identity within the network and management systems.
