Before installing or replacingDIMMs (Dual In-line Memory Modules)in a Cisco UCS server, it is essential to verify thecurrent DIMM configuration and the population order. Cisco UCS servers have strict memory population rules to ensure optimal performance and compatibility, particularly in relation to memory channels and banks.

While the type, capacity, and firmware compatibility are important, failing to follow the correct population guidelines can result in failed boot processes or suboptimal performance.

Within theFLDTECtraining, especially underMaintenance and RMA Procedures, there is a strong emphasis on safely transferring and adapting configurations from failed or decommissioned devices to replacement units.

The official guidance includes the following:

"When reusing a configuration from an old device, make sure to retain the necessary security elements such as username entries. This ensures the replacement device is still accessible under the correct user credentials."

Here's a breakdown of why the correct answer isB:

A. Remove all configurations under line vty 0 4:This would eliminate remote access settings, making it harder to manage the device.

B. Retain all username entries:Correct. Keeping the username entries ensures continued secure access and avoids loss of administrative control.

C. Keep all access-list commands intact:Not always required — ACLs are often tailored to interface-specific settings or environments which may differ between devices.

D. Add the enable password cisco command:Not a best practice. Default passwords (like cisco) should be avoided for security reasons, and it's not required if enable secret is already in use.

The highlighted component on the Cisco I/O module is the chassisconnections LED, which indicates the status of connectivity between the I/O module and the chassis.

In the exhibit, the orange arrow points to asmall rectangular LED indicatorlocated to the left side of the I/O module (Cisco UCS-IOM-2304). This specific LED isnot aligned with the ports, fans, or screws, which helps identify it correctly.

Chassis connections LED (B)is responsible for indicating thestatus of uplink/downlink communicationbetween the I/O module and the chassis.

Greenusually indicates a healthy link.

Amberoroffmay indicate a problem or no connection.

Why the other answers are incorrect:

A. Captive screw→ These are at the far corners, not where the arrow points.

C. Fan module LED→ This IOM doesn’t have user-visible fan LEDs atthe front face.

D. Fixed port→ These are the large rectangular SFP ports clearly visible in the middle, not near the arrow.

This identification is important whentroubleshooting chassis-to-IOM connectivityor verifyingmodule status LEDsduring field maintenance.

Cisco Unified Communications Manager (CUCM) is typically deployed onCisco UCS C-Series servers. These rack-mount servers provide the necessary computing resources to support CUCM's call control and session management functions in enterprise environments. The UCS C-Series servers offer scalability, reliability, and integration capabilities essential for unified communications deployments.​

Options A (Cisco ASR routers), B (Cisco Catalyst switches), and C (Cisco ISR routers) are networking devices designed for routing and switching functions and are not intended as platforms for deploying CUCM.​
