Cisco Certified Support Technician (CCST) Networking: CCST-NETWORKING

Correct Answer: C

On a Cisco switch, a port with a blinking green LED typically indicates that the port is up (active) and is currently transmitting or receiving data. This is a normal state indicating active traffic on the port.

-A. Link is up with cable malfunctions: Usually indicated by an amber or blinking amber light.

-B. Link is up and not stable: Not typically indicated by a green blinking light.

-D. Link is up and there is no activity: Would be indicated by a solid green light withoutblinking.

Thus, the correct answer is C. Link is up and active.

Correct Answer: A

Firewall: A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It permits or denies traffic based on IP addresses, port numbers, or applications. Access Point: This is a device that allows wireless devices to connect to a wired network using Wi-Fi. It does not perform traffic filtering based on IP, port, or application. VPN Gateway: This device allows for secure connections between networks over the internet, but it is not primarily used for traffic filtering based on IP, port, or application. Intrusion Detection System (IDS): This device monitors network traffic for suspicious activity and policy violations, but it does not actively permit or deny traffic.

Correct Answer:

Statement 1: Low bandwidth can increase network latency. Statement 2: High levels of network latency decrease network bandwidth. Statement 3: You can increase throughput by decreasing network latency.

Bandwidth vs. Latency: Bandwidth refers to the maximum rate at which data can be transferred over a network path. Latency is the time it takes for a data packet to travel from the source to the destination.
