Cisco CCT Practice Exam

Correct Answer: To set the name by which the device is identified in the network Explanation: The hostname [name] command, configured in global configuration mode, assigns a unique identifier (hostname) to the Cisco device, which appears in the CLI prompt and in various system outputs.

Correct Answer: To connect devices within a rack or connect a patch panel to active equipment Explanation: Patch cables (or patch cords) are relatively short, flexible cables used to make connections between patch panels and network devices (switches, routers) or directly between devices within a rack.

Correct Answer: no shutdown Explanation: The no shutdown command, when applied to an interface in interface configuration mode, enables the interface. If physical connectivity is present, the interface will then transition to an up/up state.

Correct Answer: File Transfer Protocol (FTP) Control Explanation: TCP port 21 is the standard port for the control connection of the File Transfer Protocol (FTP).

Correct Answer: show processes cpu Explanation: The show processes cpu command displays information about the CPU utilization by individual processes running on the Cisco device, useful for diagnosing performance issues.

Correct Answer: Power Distribution Unit Explanation: A PDU (Power Distribution Unit) is a device equipped with multiple output outlets designed to distribute electric power to computing equipment within a rack or data center.

Correct Answer: To avoid damage to the module or backplane connectors during insertion Explanation: Proper alignment with guide rails ensures that the module slides smoothly into the slot and its electrical connectors engage correctly with the backplane, preventing bent pins or other physical damage.

Correct Answer: To test the functionality of the local TCP/IP stack (loopback address) Explanation: Pinging the loopback address (127.0.0.1) tests whether the workstation's TCP/IP protocol stack is installed and functioning correctly, without involving the network interface card or external network.

Correct Answer: The integrity of the RJ-45 connector's locking tab and overall plug Explanation: The RJ-45 connector's locking tab is fragile and crucial for secure seating. A broken tab or damaged plug can lead to intermittent or lost connectivity.

Correct Answer: 120 Explanation: The default administrative distance for routes learned via RIP is 120, making it less preferred than directly connected (0), static (1), EIGRP (90), or OSPF (110).
