800-150 Exam Dumps : Supporting Cisco Devices for Field Technicians (FLDTEC)

The correct sequence for mounting a Cisco device in a rack is:​

Install mounting brackets: Attach the appropriate rack-mount brackets to the sides of the device using the screws provided. This step prepares the device for secure installation in the rack.​

Mount in rack: Carefully place the device into the rack, aligning the brackets with the rack posts, and secure it using the appropriate rack-mount screws.​

Ground the device: After the device is securely mounted, connect the grounding wire to the chassis grounding point and then to the facility ground. This step ensures safety and compliance with electrical standards.​

This sequence is recommended to ensure both the physical security of the device and the safety of personnel during installation.​

When connectingtwo devices of the same type(e.g., two routers, two switches, or two DTEs), acrossover cableis required. This cable swaps the transmit and receive pairs to allow direct communication between devices without the need for an intermediate device like a switch.

Straight-through cablesare used to connect different types of devices (e.g., PC to switch).

Rolled cablesare used for console access.

USB Type A to Bcables are typically used for peripheral device connections, not networking.

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.​
