A network technician is troubleshooting a workstation that cannot access resources on remote subnets or resolve domain names. The technician runs `ipconfig /all` on the workstation and receives the following output:
IPv4 Address: 169.254.184.22
Subnet Mask: 255.255.0.0
Default Gateway:
DNS Server: 10.10.1.5
Which TWO of the following statements accurately explain the host's current networking state and the required corrective actions? (Select TWO.)
- The host automatically generated an APIPA address because it was unable to contact a DHCP server to obtain an IP lease.Cevap
- The host cannot communicate with the configured DNS server at 10.10.1.5 because it lacks a valid routable IP configuration and default gateway.Cevap
- CThe DNS server at 10.10.1.5 must be updated to assign dynamic IP address leases to client hosts on this subnet segment.
- DAn unmanaged Layer 2 switch should be installed on the local segment to route APIPA traffic to the remote network.
Cevap
The host automatically self-assigned an APIPA address because it could not contact a DHCP server, and it cannot communicate with the DNS server at 10.10.1.5 due to lacking a routable IP address and default gateway.
The presence of a 169.254.x.x IPv4 address indicates that the host attempted dynamic configuration but failed to reach a DHCP server, causing the operating system to self-assign an APIPA address. Furthermore, because APIPA addresses are link-local non-routable addresses and no default gateway is assigned, the client cannot communicate beyond its local segment to access the DNS server located at 10.10.1.5.
