Exam JN0-105 topic 1 question 74 discussion

A. You can use any IGP for learning prefixes, however, if you don't have a GW IP Address configured, your traffic will be isolated from/to outside world.

Correct Answer A Users in the 10.1.1.0/24 subnet should have their default gateway set to 10.1.1.254. The server in the 10.1.2.0/24 subnet should have its default gateway set to 10.1.2.254. B. Trunk ports must be enabled on the switch: Trunk ports are used for VLAN tagging in a switch, but this scenario does not indicate the use of VLANs. C. A routing protocol must be enabled on the router: A routing protocol is not necessary in this simple setup, as static routing based on the default gateways should suffice for communication between these subnets. D. Users must connect directly to the router: This is not required. The users can connect to the router through the switch, as long as the default gateway is correctly configured.

Already tested in a lab. No routing config is needed.

I think C because although Router has IP, we do not know if routing has been enabled (eg. static route) Questions is also specifically asking for which "routing configuration" Default Gateway can configured on the clients

It's A

A is correct , networks 10.1.1.0/24 and 10.1.2.0/24 are configured on the router's interface . Routing protocols not needed.

a default-gateway is required. While both segment are direct in the same router, routing protocols is not needed.

both A and C are correct , require default gateway for users to communicate with router and required routing because different subnets .

A. Users and the server require a default gateway. This configuration ensures that the devices in different subnets (10.1.1.0/24 and 10.1.2.0/24) can communicate with each other through the router. The default gateway on each subnet points to the router's interface on that subnet, enabling the routing of traffic between the subnets.

A. Users and the server require a default gateway.

A is the answer. Routing protocols are never "required". A default gateway is always required.
