  Correct Answer: A

  Network Health:

  WAN 2 appears to have a lower average latency and loss percentage, which would make it the preferred WAN station for VoIP traffic. VoIP traffic requires low latency and packet loss to ensure good voice quality and reliability. WAN 1 seems

  to have higher RAM and processor usage, which could also affect the performance of VoIP traffic.

  Here's the summary of the key metrics for WAN 1 and WAN 2 from the image provided:

  WAN 1:

  WAN 2:

  For VoIP traffic, low latency and jitter are particularly important to ensure voice quality. While WAN 1 has higher bandwidth and throughput, it also has higher latency and jitter compared to WAN 2. However, WAN 2 has much lower loss, lower

  latency, and lower jitter, which are more favorable for VoIP traffic that is sensitive to delays and variation in packet arrival times. Given this information, WAN 2 would generally be preferred for VoIP traffic due to its lower latency, lower jitter,

  and significantly lower loss percentage, despite its lower bandwidth compared to WAN 1. The high bandwidth of WAN 1 may be more suitable for other types of traffic that are less sensitive to latency and jitter, such as bulk data transfers.

  

  Device Monitoring:

  the device that is experiencing connectivity issues is the APP Server or Router 1, which has a status of Down. This means that the server is not responding to network requests or sending any data. You may want to check the physical

  connection, power supply, and configuration of the APP Server to troubleshoot the problem.

• Question 1176:

  SIMULATION

  A network technician was recently onboarded to a company. A manager has

  tasked the technician with documenting the network and has provided the technician With partial information from previous documentation.

  Instructions:

  Click on each switch to perform a network discovery by entering commands into the terminal. Fill in the missing information using drop-down menus provided.

  

  

  

  A. See the for detailed information on this simulation. (Note: Ips will be change on each simulation task, so we have given example answer for the understanding)

  B. PlaceHolder

  C. PlaceHolder

  D. PlaceHolder

  Correct Answer: A

  To perform a network discovery by entering commands into the terminal, you can use the following steps:

  Click on each switch to open its terminal window.

  Enter the command show ip interface brief to display the IP addresses and statuses of the switch interfaces.

  Enter the command show vlan brief to display the VLAN configurations and assignments of the switch interfaces.

  Enter the command show cdp neighbors to display the information about the neighboring devices that are connected to the switch. Fill in the missing information in the diagram using the drop-down menus provided. Here is an example of how

  to fill in the missing information for Core Switch 1:

  The IP address of Core Switch 1 is 192.168.1.1.

  The VLAN configuration of Core Switch 1 is VLAN 1: 192.168.1.0/24, VLAN 2:

  192.168.2.0/24, VLAN 3: 192.168.3.0/24.

  The neighboring devices of Core Switch 1 are Access Switch 1 and Access Switch 2.

  The interfaces that connect Core Switch 1 to Access Switch 1 are GigabitEthernet0/1 and GigabitEthernet0/2.

  The interfaces that connect Core Switch 1 to Access Switch 2 are GigabitEthernet0/3 and GigabitEthernet0/4.

  You can use the same steps to fill in the missing information for Access Switch 1 and Access Switch 2.

  D. PlaceHolder

  Correct Answer: A

  Switch 1 and Switch 2 is the only two switches that can be configured. Only switches linked together with there switch ports needs to be "tagged" and "LACP" needs to be enabled. The other ports must be untagged with no LACP enabled.

  You only need to assign the correct vlan via each port. 'Speed and Duplex' needs to be Speed=1000 and Duplex=Full, with is by default.
