A network technician is reviewing host IP configuration symptoms across several workstations on a corporate subnet. Match each observed network diagnostic symptom on the left with its underlying configuration cause or mechanism on the right.
- A workstation receives an IP address of 169.254.108.44 and cannot access internal local network shares or the internet.Automatic Private IP Addressing (APIPA) assignment triggered by DHCP unreachability
- A host can ping local devices on the 192.168.10.0/24 subnet but fails to reach any hosts on external networks.Missing or misconfigured Default Gateway address
- A computer can ping internet servers using their public IP address (such as 1.1.1.1) but fails to load web pages using domain names.Unreachable or misconfigured Domain Name System (DNS) server
- A network printer dynamically receives the exact same IP address from the server every time its network adapter boots.DHCP reservation configured using the device MAC address
Cevap
169.254.x.x address correlates with APIPA assignment due to unreachable DHCP; local connectivity without external access correlates with a Default Gateway misconfiguration; successful IP ping with failed hostname resolution correlates with a DNS server misconfiguration; consistent dynamic IP assignment correlates with a DHCP reservation.
Each diagnostic symptom directly correlates with a fundamental networking role: APIPA (169.254.0.0/16) occurs when a client fails to receive a DHCP response; a default gateway routes traffic beyond the local subnet; DNS translates domain names to IP addresses; and a DHCP reservation dynamically assigns a specific IP to a fixed MAC address.
