350-401 Architecture Practice Question
A network engineer is deploying a new Cisco wireless network using a 9800 Series Wireless Controller. The engineer wants to ensure that the management interface is properly configured for out-of-band management. Which interface type should be configured with an IP address for management access?
⚠ Common exam trap
The trap here is assuming that the service port or virtual interface can be used for management access, when they serve different roles.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Management interface
The management interface on a Cisco 9800 Series Wireless Controller is specifically designed for out-of-band management. It requires an IP address, subnet mask, and default gateway to allow administrators to access the controller via SSH, HTTPS, or SNMP. Other interfaces like the redundancy management interface, service port, and virtual interface serve different purposes and are not used for primary management access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Virtual interface
Why it's wrong here
The virtual interface on a Cisco wireless controller is used for client mobility and DHCP relay, not for management access. It must be configured with an IP address (typically 192.0.2.1) but is not reachable from external networks. It is an internal interface used for client traffic handling, not administrative access.
- ✗
Redundancy management interface
Why it's wrong here
The redundancy management interface is used for communication between controller pairs in a high availability setup. It is not used for general out-of-band management access. While it may have an IP address, it serves a specific purpose for redundancy and should not be used for management access by administrators.
- ✗
Service port
Why it's wrong here
The service port on a Cisco 9800 Series Controller is used for out-of-band management in some deployments, but it is not the primary management interface. The service port is typically used for initial configuration or when the management interface is not available. It does not support all management functions and is not the recommended interface for ongoing management.
- ✓
Management interface
Why this is correct
The management interface on a Cisco 9800 Series Wireless Controller is used for out-of-band management, including device access via SSH, HTTPS, and SNMP. It must be configured with an IP address, subnet mask, and default gateway. This interface is separate from data interfaces and is essential for administrative access to the controller.
