Before shutting down any Cisco collaboration device (such as an IP phone, video endpoint, or codec) for replacement, it is essential to back up the configuration. This ensures that all custom settings, including user profiles, network configurations, and service settings, are preserved and can be quickly restored on the replacement device.

This backup minimizes downtime and avoids manual reconfiguration errors during the swap process.

In the hierarchical network design model, the access layer is the first layer and serves as the entry point for end-user devices to connect to the network. This layer connects user devices such as PCs, IP phones, wireless access points, printers, and scanners to the network. It facilitates the initial connection between end-user devices and the network infrastructure. The access layer also enforces security policies and provides services such as VLAN membership, port security, and Quality of Service (QoS).

Options A, C, and D refer to functions typically associated with the core or distribution layers, or with WAN connectivity, rather than the access layer.

In the Infrastructure as a Service (IaaS) model, the cloud provider is responsible for managing and maintaining the underlying infrastructure components, including:

Networking: The cloud provider handles all aspects of network configuration, hardware, and virtual networking.

Storage: The cloud provider supplies and manages the physical and virtual storage infrastructure required to support the consumer's data needs.

The customer is responsible for managing:

Operating Systems

Applications

Data

This model offers flexibility while shifting infrastructure maintenance responsibilities to the service provider.

The highlighted components in all three Cisco UCS server models (5108 B-Series Blade Server Chassis, X9508 X Series Modular Server Chassis, and C225 M6 Rack Server) are fan modules, which are field-replaceable units responsible for cooling the system.

The highlighted components in the images correspond to cooling fans --- these are essential for maintaining optimal thermal conditions within each Cisco UCS server type. Here's a breakdown of what's visible in each:

Cisco UCS 5108 B-Series Blade Server Chassis: The highlighted vertical rectangular components are fan modules, which provide high-efficiency airflow for the densely packed blades.

Cisco UCS X9508 X-Series Modular Server Chassis: The front-facing fan trays are clearly marked, used to cool the modular nodes and shared infrastructure.

Cisco UCS C225 M6 Rack Server: The highlighted components on the side of the motherboard are also fan modules, directly responsible for cooling the CPU, memory, and other internal components.

These fans are field-replaceable units (FRUs) and are routinely accessed by technicians during preventive maintenance or fault replacement.

When replacing a fabric interconnect in a Cisco Unified Computing System (UCS), the recommended procedure to minimize traffic disruption is to use the fabric evacuation procedure on the subordinate fabric interconnect. This ensures that traffic is redirected to the other (active) fabric interconnect, allowing the system to maintain connectivity while one interconnect is replaced.

High availability should remain enabled to preserve redundancy.

Powering down both interconnects would cause a complete outage.

Disconnecting cables without graceful evacuation can result in traffic loss.
