Cisco 800-150 Dumps

A speed mismatch occurs when two connected Ethernet devices are configured to operate at different speeds. In scenario A, one device is manually set to 1 Gbps, while the other is set to 100 Mbps. Since both ends are hard-coded to different speeds, they cannot successfully negotiate a common speed, leading to a mismatch and resulting in a failed or unstable link.​

In contrast, scenario B, where both ends are manually set to the same speed, ensures compatibility and stable communication. Scenario C can lead to a duplex mismatch rather than a speed mismatch; the auto-negotiating end may default to half-duplex if it cannot determine the duplex setting of the manually configured end. Scenario D is less common; if auto-negotiation fails, devices may revert to their lowest common speed, but this typically results in reduced performance rather than a complete mismatch.​

The Cisco Collaboration Infrastructure is designed to support unified communications, video conferencing, and team collaboration through an integrated architecture involving both hardware (e.g., endpoints, media servers) and software (e.g., CUCM, Webex apps).

According to the FLDTEC course content under Cisco Collaboration Equipment and Infrastructure:

Facilitating Connections (C):

Cisco infrastructure components such as CUCM, Expressway, and Cisco Meeting Server enable real-time connections between users across voice, video, and messaging systems.

Supporting Meeting Experiences (E):

Devices such asWebex Boards, Room Kits, and Cisco Quad Cameras, in combination with platforms like Webex, provide immersive and seamless meeting experiences, supported by the infrastructure.

Incorrect Options:

A. Network bandwidth allocation: Typically managed by network QoS policies and WAN optimizations, not the collaboration infrastructure directly.

B. Hosting large-scale databases: Not a function of Cisco’s collaboration system — this falls under data center or database server roles.

D. Phone book administration: Often a function within directory services or external LDAP integration, not a core collaboration infrastructure task.

In Cisco Nexus switches, when transitioning from a single supervisor module to a dual supervisor configuration, the behavior depends on the redundancy mode configured.​

Stateful Switchover (SSO):In configurations supporting SSO, the active and standby supervisors synchronize their state and configuration, allowing for seamless failover without resetting other modules.​

Stateless Switchover (Warm Standby):In certain modes, such as the ACI-mode on Cisco Nexus 9508 switches, the standby supervisor does not maintain synchronized state information with the active supervisor. In this scenario, if a switchover occurs (e.g., due to the replacement of the active supervisor), all modules in the switch are reset because the switchover is stateless.​

Therefore, when a supervisor module is replaced in a configuration that does not support stateful switchover, all modules in the switch are reset due to the stateless nature of the switchover.​
