7
What is the primary purpose of Cisco Discovery Protocol (CDP)?
To encrypt data between two Cisco devices
To perform performance baselining on network links
To assign IP addresses dynamically to Cisco devices
Discover directly connected Cisco devices and gather info for documentation
8
On Linux host, which command is most commonly used in a terminal to display the status of all active network interfaces?
ipconfig
ifconfig
netstat
show interfaces
9
What is the difference between bandwidth and throughput?
Bandwidth in packets/sec; throughput in bits/sec.
Bandwidth is theoretical max data rate; throughput is actual data rate.
Bandwidth applies to wireless; throughput to wired.
Bandwidth measures CPU use; throughput measures memory use.

12
Active listening in a help desk scenario includes which of the following actions?
Avoiding eye contact and multitasking while they speak
Interrupting the user frequently to speed up the process
Let the user finish talking, then summarize to confirm understanding
Immediately jumping to a solution without gathering details
13
When applying the bottom-up structured troubleshooting method, where does the technician begin?
By replacing hardware components randomly
By comparing working and nonworking systems
With user applications at the top of the OSI model
At the physical layer and move up through the OSI layers
14
What is the primary difference between a site-to-site VPN and a remote-access VPN?
Remote-access VPNs only support IPv6, site-to-site only supports IPv4
Site-to-site VPNs encrypt data, remote-access VPNs do not
Site-to-site VPNs link networks; remote-access VPNs link clients.
Remote-access VPNs require hardware appliances; site-to-site VPNs do not
