A technician is configuring a static IP network profile for a desktop workstation on a corporate network segment (). The workstation can successfully ping local hosts on , but cannot access external websites or ping servers on adjacent subnets. Running `ipconfig /all` displays the following settings:
- IP Address:
- Subnet Mask:
- Default Gateway:
- Preferred DNS Server:
Which of the following statements accurately explain why off-subnet network traffic is failing? (Select TWO.)
- The default gateway address is assigned to a different logical subnet than the host workstation.Cevap
- The workstation cannot resolve the MAC address of the default gateway via ARP because the gateway is outside the local broadcast domain.Cevap
- CThe host workstation has automatically defaulted to an APIPA configuration due to a failed DHCP lease request.
- DThe DNS server is misconfigured to lease dynamic IP addresses rather than performing hostname resolution.
Cevap
Remote connectivity fails because the default gateway () is assigned to a different IP subnet than the host (), preventing the host from using local Address Resolution Protocol (ARP) to reach its gateway.
For a host to communicate with remote networks, its default gateway must be located on the same local IP subnet. With host address and subnet mask , the gateway must reside within the – range. Because the gateway is configured as , it sits outside the host's local subnet. As a result, the workstation's ARP requests for will go unanswered, preventing off-subnet packet encapsulation.
