Exam 220-1101 topic 1 question 531 discussion

Running the described tests on a laptop with a wireless NIC will provide the following information: B. Connection latency: The ping tests (ping of the default gateway and ping of the localhost) will help determine the latency or delay in establishing communication with these destinations. Higher latency could indicate network congestion or connectivity issues. E. Subnet mask of the network: Traceroute (tracert) to the IP address of the default gateway will provide information about the path taken by packets to reach the default gateway. Additionally, it may reveal details about the subnet mask used in the network configuration.

B. Connection latency The ping and tracert commands measure response times, helping to determine network latency between the laptop and the default gateway. C. Firewall status If the ping of the localhost (127.0.0.1) fails, it could indicate that the local firewall is blocking ICMP requests, which suggests a firewall is active. A. DNS suffix – These tests check connectivity, not DNS settings. The ipconfig /all command would show the DNS suffix. D. Wireless signal strength – These commands do not measure signal strength. A tool like netsh wlan show interfaces (Windows) or iwconfig (Linux) would provide this information. E. Subnet mask of the network – The subnet mask is not determined by these tests; it is found using ipconfig or ifconfig. F. MAC address of the wireless NIC – MAC addresses are not revealed by these tests. The MAC address can be found using ipconfig /all or getmac.

B&E answers are correct By running the specified tests (ping of the default gateway, ping of the localhost, and tracert of the IP address of the default gateway), the technician can find connection latency and the subnet mask of the network. Connection latency: The time it takes for a ping or tracert command to send and receive a response helps in determining the latency in the network connection. Higher latency values can indicate delays in communication over the network. Subnet mask of the network: The ipconfig command, which the technician would initially run to perform these tests, provides various details about the network configuration, including the subnet mask. The subnet mask is essential in determining the network and host portions of an IP address, which is crucial for networking and troubleshooting connectivity issues

I'm going with B and C. The tests mentioned (pinging the default gateway, pinging localhost, and running a tracert) do not directly provide the subnet mask of the network (Option E). These commands are primarily used to check connectivity and latency, not to reveal network configuration details like the subnet mask. To find the subnet mask, you would typically use commands like ipconfig (on Windows) or ifconfig (on Unix-based systems), which display detailed network configuration information.

B & E is correct

BE should be highlighted as correct. Not BC

The technician will find the following: B. Connection latency: Ping tests measure the round-trip time for packets to reach a destination and return, providing information about network latency. E. Subnet mask of the network: The ping and traceroute commands can provide information about the network configuration, including the subnet mask. The other options are not directly related to the tests performed: A. DNS suffix: DNS suffixes are used to resolve domain names and are not typically revealed by ping or traceroute tests. C. Firewall status: Firewall settings can affect network connectivity, but they are not directly visible in the output of ping or traceroute commands. D. Wireless signal strength: While wireless signal strength can affect network performance, it's not directly measured by ping or traceroute. F. MAC address of the wireless NIC: The MAC address is a hardware identifier and is not typically displayed in the output of ping or traceroute commands. GG
