A network administrator is conducting a comprehensive network analysis on a workstation experiencing connectivity and resolution issues. Match each command-line utility command on the left with its primary diagnostic function on the right.
- pathping 192.168.10.1Measures packet loss and latency at each network hop over a sustained evaluation period.
- arp -aDisplays the local Layer 2 MAC address mapping for known IP addresses.
- netstat -anoLists all active network connections, listening ports, and their associated Process IDs (PIDs).
- dig -x 10.0.0.50Performs a reverse DNS lookup to determine the domain name associated with an IP address.
Cevap
pathping 192.168.10.1 matches with measuring packet loss and latency per hop; arp -a matches with displaying local MAC address mappings; netstat -ano matches with listing active connections, listening ports, and Process IDs; dig -x 10.0.0.50 matches with performing reverse DNS lookups.
Each command-line tool maps directly to its intended OSI layer and operational troubleshooting purpose: pathping measures per-hop packet loss over time, arp -a displays Layer 2 MAC cache tables, netstat -ano correlates listening sockets to Process IDs, and dig -x performs reverse DNS resolution.
