• YES
• NO

What are the general steps in establishing the Network Baseline? (More than 1 answer)

• Determine types of data to collect
• Identify devices and ports of interest
• Determine baseline duration
• Determine the outcome of the baseline performance

Which is the correct troubleshooting procedure?

• Gather Symptoms > Isolate problem > Implement corrective action > Document if resolved, else start from beginning
• Gather Symptoms > Implement corrective action > Document if resolved
• Gather Symptoms > Implement corrective action > Document if resolved, else start from beginning
• Gather Symptoms > Isolate problem > Implement corrective action

Which principle of Structured Engineering reflects the ability to modify portions of the network, add new services, or increase capacity without going through a major fork-lift upgrade?

• Hierachy
• Modularity
• Resiliency
• Flexibility

Which of the following is correct about the "Educated Guess" approach in troubleshooting.

• Need to have extensive knowledge and experience to identify the root cause based on symptoms of problem
• Compare a working and nonworking situatio and spot significant differences
• Replace problematic device with a known, working one is a quick way to troubleshoot

Which of the following is correct about the "Bottom-up" approach in troubleshooting.

• Troubleshooting starts from physical layer and physical components of network and move up through the layers of the OSI model until problem is identified
• Troubleshooting starts from end-user applications and moves down through the layers in the OSI model until problem is identified

Which approach in troubleshooting starts by collecting info about the problem to make informed decision on which OSI layer to start investigation. When layer is verified functioning, it is assumed layer below are functioning

• Bottom-up
• Top-down
• Divide-and-Conquer
• Follow-the-path

• YES
• NO

The "Telnet" command is used to verify the Transport layer

• YES
• NO
