Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  ping: Tests connectivity to a remote host

  Why this is correct

  In Windows, ping is a diagnostic utility that sends Internet Control Message Protocol (ICMP) Echo Request packets to a specified destination IP address or hostname and listens for Echo Reply packets. A successful reply confirms end-to-end IP-level connectivity and round-trip latency, while timeouts or 'Destination Host Unreachable' errors indicate network path failures. This makes ping the go-to first step for verifying basic Layer 3 reachability before investigating higher-layer protocols or services.

  tracert: Traces the route packets take to a destination

  Why this is correct

  tracert (short for 'trace route') is a Windows command-line tool that maps the network path from the local host to a destination by sending ICMP Echo Requests with incrementally increasing Time-to-Live (TTL) values. As each router along the path decrements the TTL to zero, it sends back an ICMP Time Exceeded message, revealing that router's IP address and the round-trip time (RTT) for each hop. This command is essential for identifying where packets are being dropped or where latency spikes occur across multi-hop networks, such as the internet or a large enterprise WAN.

• ✓

  ipconfig: Displays IP configuration

  Why this is correct

  ipconfig is the Windows utility that displays the current TCP/IP network configuration for all active network adapters on the system. By default it shows the IPv4 address, subnet mask, and default gateway; when used with the /all switch, it also reveals MAC addresses, DHCP lease information, and DNS server assignments. This command is the first stop for verifying whether a workstation has obtained a valid IP address, is on the correct subnet, and has the proper gateway and DNS settings to reach other networks.

• ✓

  netstat: Displays network connections and listening ports

  Why this is correct

  netstat (network statistics) is a command-line tool that displays active TCP and UDP connections, listening ports, and protocol statistics on a Windows machine. When run without arguments, it lists established connections with local and foreign addresses and their connection states (e.g., ESTABLISHED, LISTENING). This is invaluable for detecting unexpected open ports, verifying that a service is bound to the correct interface, or identifying suspicious outbound connections that might indicate malware or unauthorized activity.

• ✗

  ping: Displays IP configuration

  Why it's wrong here

  Selecting ping for this description is incorrect because displaying IP configuration is the job of ipconfig, not ping. ping operates at the network layer (Layer 3) by sending ICMP echo requests to test reachability; it does not read or report the local system's IP address, subnet mask, or default gateway. While ping can resolve a hostname to an IP and show the reply's source address, it never enumerates the local adapter's TCP/IP settings, which is the specific function that belongs to ipconfig.

• ✗

  ipconfig: Traces the route to a destination

  Why it's wrong here

  Attributing route tracing to ipconfig is a mistake: ipconfig is purely a local configuration reporting tool, whereas the route-tracing task describes tracert. ipconfig retrieves and displays current TCP/IP settings from the local system's adapter configuration and DHCP client, showing static values or leased addresses—it never sends packets out to the network or interacts with intermediate routers. Only tracert uses ICMP with incrementing TTL values to elicit responses from each hop, revealing the path packets take to a remote destination.
