Suggested answer: B, E

Explanation:

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.

CompTIA A+ Core 1 (220-1101) Exam Objectives, specifically sections dealing with troubleshooting network connectivity issues and understanding network configurations, including the use of diagnostic commands like ping and tracert.

Networking fundamentals, which explain the purpose and use of diagnostic tools such as ping (to measure latency) and ipconfig (to view IP configuration details including the subnet mask).
