A network technician is diagnosing workstation configuration issues following a network migration. Match each observed host symptom to its most likely underlying root cause.
- Workstation self-assigns an IP address in the range to and can only communicate with other hosts on the same physical link.Unreachable DHCP server or failed lease negotiation, causing the client to fall back to Automatic Private IP Addressing (APIPA).
- Workstation can successfully reach internal web portals using direct IP addresses like , but fails to load web pages using domain names such as corporate.local.Unreachable or incorrectly configured DNS server addresses.
- Workstation communicates normally with local hosts on the subnet, but cannot send packets to servers located on the subnet.Misconfigured or missing Default Gateway address on the host network interface.
- Workstation displays an IP address collision alert shortly after joining the network using dynamic configuration settings.Overlapping static IP assignment within the DHCP server's active scope range.
Cevap
Matching pairs:
- Self-assigned address matches Unreachable DHCP server causing APIPA fallback.
- Access by direct IP success but hostname failure matches Unreachable or incorrectly configured DNS server.
- Local subnet communication success but remote subnet failure matches Misconfigured or missing Default Gateway.
- IP address collision alert matches Overlapping static IP assignment within the active DHCP scope range.
- Self-assigned address matches Unreachable DHCP server causing APIPA fallback.
- Access by direct IP success but hostname failure matches Unreachable or incorrectly configured DNS server.
- Local subnet communication success but remote subnet failure matches Misconfigured or missing Default Gateway.
- IP address collision alert matches Overlapping static IP assignment within the active DHCP scope range.
Each diagnostic symptom directly correlates with a specific TCP/IP configuration component: APIPA () indicates a missing DHCP lease response; inability to resolve hostnames while IP routing works points to DNS misconfiguration; loss of off-subnet routing while retaining intra-subnet connectivity indicates a default gateway misconfiguration; and dynamic IP address conflicts stem from static IPs existing within active DHCP scopes.
