A workstation running Windows 11 is relocated to a new corporate subnet ( $10.0.4.0/24$ ). A technician manually assigns a static IPv4 address of $10.0.4.45$ and a subnet mask of $255.255.255.0$ . The workstation can successfully ping other host computers on the local $10.0.4.0/24$ subnet, but users report that it cannot reach external internet web servers or resolve public domain names. Which TWO of the following IPv4 properties must be properly configured on the client network adapter to resolve these issues? (Select TWO.)

Default gateway IP address matching the local subnet router interfaceAnswer
Preferred DNS server IP address capable of resolving domain namesAnswer
C
WINS server address designated for external packet forwarding
D
Remote Desktop Gateway path configured in the Control Panel System applet

Answer

The correct answers are the default gateway IP address matching the local subnet router interface and the preferred DNS server IP address capable of resolving domain names.

For a Windows client to communicate beyond its local subnet and resolve website addresses, it must have a Default Gateway configured (to route packets out of the subnet) and a Preferred DNS Server configured (to translate domain names into IP addresses).

Step-by-Step Solution

Analyze local vs. remote network communication symptoms

The client host can communicate within its local

10.0.4.0/24

subnet, confirming that the static IP address and subnet mask are valid for Layer 2 and Layer 3 local communications.

Local traffic does not require a router or gateway to cross network boundaries.

Identify the required setting for out-of-subnet routing

Assigning a Default Gateway address allows the client to send traffic destined for external networks to the local router.

Without a default gateway configured in TCP/IPv4 properties, packets addressed to IP addresses outside the local subnet mask range are dropped.

Identify the required setting for hostname resolution

Assigning a Preferred DNS server address enables the workstation to query domain name servers.

Without a functional DNS server assigned, the client cannot resolve human-readable domain names into IP addresses.
