800-150 Exam Dumps and Practice Questions

In the FLDTEC course, the process for removing or replacing a supervisor module --- especially the standby supervisor --- in a modular switch like the Cisco MDS 9700 is clearly outlined. Cisco documentation states:

'Before removing a standby supervisor module, it must first be placed into out-of-service mode using the CLI command system no supervisor <slot-number> or via the appropriate management interface.'

This action ensures the system acknowledges the supervisor is no longer participating in redundancy, allowing a safe and controlled removal without impacting system operations.

Why not the other options?

A . Shut down the entire switch Not required; MDS switches are built for high availability and allow hot-swap operations.

C . Disconnect all network interface cables This applies to line cards or interfaces, not to supervisor removal specifically.

D . Perform a manual failover Failover is required when removing the active supervisor, not the standby one.

In a blade server environment, the chassis serves as the enclosure that houses multiple blade servers. It provides shared power, cooling, and connectivity resources. Blade servers are compact server modules that insert into the chassis, and the shared infrastructure makes the entire system efficient in space, power, and management.

The chassis does not act as a switch or storage array itself but provides interconnects and sometimes integrated networking components.

A Network Interface Card (NIC) is essential for device connectivity. Two common symptoms indicating that a NIC may be faulty and require replacement are:

Connectivity problems (Option A): Devices may fail to communicate with the network, showing no IP address assignment or inability to ping/connect to other devices.

Consistent link down status (Option D): The link LED may stay off or frequently go down, even when connected to a functioning switch port with a known-good cable.

Other options like configuration issues (Option B) or system crashes (Option E) might be due to software or unrelated hardware components, and boot failures (Option C) typically point to motherboard or storage faults.

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 as Webex 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.

Cisco Webex Calling is a cloud-based, enterprise-grade PBX (Private Branch Exchange) solution designed to provide comprehensive voice communication services via the Webex cloud platform. It enables IP phones and softphones to register to the cloud, allowing for centralized call control, voicemail, and collaboration features without the need for an on-premises call manager.

Cisco Hosted Collaboration Solutions are partner-hosted services.

Webex Meetings supports virtual video conferencing.

Webex Teams (now part of Webex App) supports messaging and collaboration, not PBX functionality.
