Actual exam question from CompTIA's 220-1101

Question #: 135
Topic #: 1

A customer is using a satellite internet connection that is experiencing slowness. A technician notices high latency while pinging, but the download test is performing perfectly with very good download speeds. Which of the following represents the NEXT action the technician should perform?

A. Restart the modem and run an online internet connection and speed diagnostic tool.
B. Guide the customer on how to upgrade the internet plan with the provider in order to improve latency
C. Explain to the customer this is not an issue; this situation is normal for this type of internet connection.
D. Replace the modem because it is not working correctly based on the test result.

I think A is correct, it is asking what is the NEXT step we should take, I have at times just skipped down to the solution or telling the customer was is wrong right away without fully going through the necessary steps needed to test everything and documenting it. Eventually we will end up telling the customer that this is normal for satellite connectivity but we want to make sure we do our due diligence as technicians to go through the troubleshooting steps that are laid before us

I agree with A being correct. While its certainly true satellite connections have latency issues, restarting a modem can help to clear out any temporary issues that may be causing high latency.

Satellite suffers from high latency naturally and restarting the modem won't fix that.

Selected Answer: A

The technician should restart the modem and run an online internet connection and speed diagnostic tool1 . High latency is a common issue with satellite internet connections, and it can cause slow internet speeds2 . Restarting the modem can help to resolve the issue1. The technician should also run an online internet connection and speed diagnostic tool to check the connection and speed1. Guiding the customer on how to upgrade the internet plan with the provider in order to improve latency is not likely to be the correct option2.

High latency while pinging can indicate a problem with the modem or the connection between the modem and the satellite. Restarting the modem can often resolve connectivity issues. Running an online internet connection and speed diagnostic tool can help identify any other issues with the connection. Upgrading the internet plan may not resolve latency issues and may not be necessary if the download test is performing perfectly with very good download speeds. High latency is not normal for satellite internet connections, so replacing the modem based on this one test result is premature. References: CompTIA A+ Certification Exam: Core 1 - Page 102

You already ran speed tests and resetting the modem would be completely pointless as you aren't magically getting those satellites any closer. C is the only valid answer.

assume tht the customer hve no experienced with slowness before.. Meaning previously the connection speed was OK. So my aswer is A

C might seem right due to latency issue but A would be applicable as after trying A and ensuring all other options are exhausted. So First A (if not then D, C and B) in that order. Maybe I am wrong but this makes sense

High latency is a given with Satellite. Round trip to satellite in geo syncronous orbit is 72,000KM. Therefore there will always be a latency issue. The download is very good, they state that in the question. Restarting a modem isnt a bad idea but wont solve anything here. So Answer is C

Answer is C. Speed tests have already been performed. As per CompTIA's textbook: One drawback of satellites placed in a high geostationary orbit is increased latency. The signal must travel over thousands of miles more than terrestrial connections, introducing a delay of many times what might be expected over a land link. For example, if accessing an internet web server over DSL involves a 10–20 ms round trip time (RTT) delay on the link, accessing the same site over a satellite link could involve a 600–800 ms RTT delay. This is an issue for real-time applications, such as video conferencing, VoIP, and multiplayer gaming.

Selected Answer: A

The answer is A, restart the modem and run an online internet connection and speed diagnostic tool. High latency is typically caused by a problem with the modem or the internet connection itself. Restarting the modem can often fix this problem by clearing any temporary errors that may be causing the high latency. Running an online internet connection and speed diagnostic tool can also help to identify the source of the problem.

Restart is a good option, however the tech has already ran these speed tests.

Selected Answer: A

A. Restart the modem and run an online internet connection and speed diagnostic tool. Explanation: In this scenario, the high latency indicates a delay in the transmission of data, which could be caused by a number of factors. However, since the download test is performing perfectly, it suggests that the issue is not with the internet plan or the modem itself. Therefore, the best course of action for the technician is to restart the modem to see if it can help alleviate the issue and then run an online internet connection and speed diagnostic tool to further troubleshoot and identify the cause of the latency.

Selected Answer: A

A. Restart the modem and run an online internet connection and speed diagnostic tool. The technician should restart the modem and run an online internet connection and speed diagnostic tool to identify the root cause of the issue. High latency can be caused by a variety of factors, such as network congestion, outdated firmware, or issues with the modem itself. Restarting the modem and running an online diagnostic tool can help the technician determine if the issue is with the modem or with the network and identify any potential solutions.
