Zorluk: OrtaIP Addressing and Network Configuration

A technician is troubleshooting a workstation on subnet 10.20.4.0/2410.20.4.0/24. The workstation can successfully ping other hosts on the local subnet by IP address, but it cannot access internet websites by domain name or reach server resources on remote subnets. Running `ipconfig /all` displays the following network settings:

- IPv4 Address: 10.20.4.8810.20.4.88
- Subnet Mask: 255.255.255.0255.255.255.0
- Default Gateway: 10.20.4.8810.20.4.88
- Preferred DNS Server: 10.20.4.8810.20.4.88

Which of the following configuration steps should the technician perform to resolve the connectivity issues? (Select TWO.)

  1. Update the Default Gateway setting to point to the local router interface IP address.Cevap
  2. Specify the IP address of an active DNS server to handle hostname resolution.Cevap
  3. C
    Configure the workstation to rely on APIPA to obtain a 169.254.x.x169.254.x.x address for external subnet routing.
  4. D
    Reconfigure the local unmanaged Layer 2 switch to act as the primary DHCP and DNS resolution host.

Cevap

The technician must update the Default Gateway setting to the local router interface IP address and configure a valid DNS server IP address.
Updating the Default Gateway to the router's IP address allows packets destined for other networks to be routed appropriately. Specifying a functional DNS server enables the workstation to translate hostnames into IP addresses, restoring domain-based connectivity.

Adım Adım Çözüm

1
Analyze the ipconfig /all output
Determined that Default Gateway and Preferred DNS Server are set to the host's own IP address (10.20.4.8810.20.4.88).
A host configured with its own IP address as gateway and DNS cannot forward traffic off-subnet or resolve hostnames.
2
Correct the Default Gateway configuration
Enter the IP address of the local network router (e.g., 10.20.4.110.20.4.1).
The default gateway routes network packets intended for destinations outside the local 10.20.4.0/2410.20.4.0/24 network.
3
Correct the DNS Server configuration
Enter the IP address of a reachable DNS server.
A functional DNS server translates user domain requests into numeric IP addresses required for network communication.
