Important Cisco 800-150 FLDTEC Exam Questions

Answer: A

Explanation:

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.

Answer: B

Explanation:

The install all command is the standard method used to install or upgrade Cisco NX-OS software on Nexus switches. This command streamlines the installation process by automating tasks such as verifying the software image, checking for compatibility, and managing the installation of optional packages or SMUs (Software Maintenance Upgrades). It ensures a comprehensive and efficient upgrade process, minimizing the potential for errors.Cisco

In contrast:

copy tftp: running-config is used to copy configuration files, not software images.

install kickstart is an outdated command from earlier NX-OS versions.

boot system sets the boot variable but does not handle the full installation process.

Answer: B, C

Explanation:

In enterprise networking, remote sites or branch offices connect to the central campus network using:

WAN Links: These are dedicated communication paths that connect geographically dispersed networks. WAN links can be leased lines, MPLS circuits, or other forms of long-distance connectivity that facilitate reliable data transmission between remote sites and the main campus.

IPsec VPN Tunnels: Internet Protocol Security (IPsec) VPNs provide secure, encrypted tunnels over the public internet, allowing remote sites to connect to the enterprise network securely. This method is cost-effective and widely used for connecting branch offices to the central network infrastructure.

Access layer switches (Option A) and LAN core switches (Option E) are components within a local network and do not facilitate remote connectivity. Ad hoc Wi-Fi networks (Option D) are temporary and lack the security and reliability required for enterprise-level remote connections.

Answer: B

Explanation:

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.

Answer: A

Explanation:

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.
