SIMULATION
A network technician needs to resolve some issues with a customer's SOHO network. The customer reports that some of the devices are not connecting to the network, while others appear to work as intended.

INSTRUCTIONS

Troubleshoot all the network components and review the cable test results by clicking on each device and cable. Type help in each terminal to view a list of available commands.
Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

Router and Firewall Configuration:
Ensure that all routers are configured with correct static routes to facilitate proper network traffic routing between different VLANs and external networks.
Install a firewall at the network's entry point to inspect and filter Internet traffic as required by the security policy.
Switch Configuration:
Configure switches to ensure PCs in different VLANs do not see each other's traffic. Implement VLAN tagging on the switches to segregate traffic between the different departments as indicated.
Cable Test Results:
Address any faulty cables as indicated by the test results. For example, any cable showing physical connection issues (crossed pairs, etc.) should be replaced.
Ensure that cables are appropriately labeled and meet the length requirements to avoid potential transmission issues over long distances.
Device Specific Issues:
For devices showing incorrect configuration details such as bad IP addresses, subnet masks, or DNS configurations, apply appropriate corrections. For instance, resetting IP configurations or updating DNS settings where mismatches are found.
Printer Configuration:
Check the printer configuration to ensure it aligns with the network settings, particularly the IP address, subnet, and gateway to guarantee connectivity for all users needing access.
Overall Network Health:
Continuously monitor the network for any emerging issues, perform regular updates to the firmware of network devices, and ensure compliance with the latest security standards to maintain network integrity and performance.



SIMULATION
After a recent power outage, users are reporting performance issues accessing the application servers. Wireless users are also reporting intermittent Internet issues.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

WAN 1:
Uplink Speed: 10G
Total Usage: 26.969GB Up / 1.748GB Down
Average Throughput: 353MBps Up / 23.42MBps Down Loss: 2.51%
Average Latency: 24ms Jitter: 9.5ms
WAN 2:
Uplink Speed: 1G
Total Usage: 930GB Up / 138GB Down
Average Throughput: 12.21MBps Up / 1.82MBps Down Loss: 0.01%
Average Latency: 11ms Jitter: 3.9ms
Although WAN 1 offers greater bandwidth and throughput, it exhibits higher latency and jitter, which could detract from VoIP performance. In contrast, WAN 2, despite its lower bandwidth, offers much lower latency, nearly negligible packet loss, and reduced jitter. These characteristics are essential for VoIP applications, which demand consistent and quick packet delivery.
Therefore, for VoIP communications, WAN 2 is recommended due to its enhanced stability in latency and jitter handling, which are pivotal for the clarity and reliability of voice calls. WAN 1 could be better utilized for other tasks that require high bandwidth and are less affected by latency variations, such as large-scale data transfers.



Which of the following steps of the troubleshooting methodology would most likely include checking through each level of the OSI model after the problem has been identified?

  1. Establish a theory.
  2. Implement the solution.
  3. Create a plan of action.
  4. Verify functionality.

Answer(s): A



While troubleshooting a VoIP handset connection, a technician's laptop is able to successfully connect to network resources using the same port. The technician needs to identify the port on the switch. Which of the following should the technician use to determine the switch and port?

  1. LLDP
  2. IKE
  3. VLAN
  4. netstat

Answer(s): A
