A company has two VLANs on the same switch: VLAN 10 (192.168.10.0/24) and VLAN 20 (192.168.20.0/24). The switch is currently a Layer 2 switch. The company wants hosts in VLAN 10 to communicate with hosts in VLAN 20 without adding a separate router. What should be done?

Change the subnet mask on all hosts to 255.255.0.0.

Configure static routes on the switch pointing to each VLAN.

Connect the two VLANs with a crossover cable between two access ports.

Replace the switch with a Layer 3 switch and configure SVIs for each VLAN.

A small office has a single router connected to the internet. A workstation is configured with IP address 192.168.1.10/24 and needs to reach a web server at 203.0.113.5. The workstation's routing table shows only its directly connected network. What must be configured on the workstation for this traffic to leave the local network?

A second IP address on the workstation in the 203.0.113.0/24 network

A static route to 203.0.113.5 via the router's WAN interface

A default gateway pointing to the router's LAN interface

A DNS server address on the workstation

A school has a single switch connecting all computers in one subnet. The school wants to separate student and teacher traffic into different VLANs for security. They also want to allow teachers to access student resources. What is the simplest way to achieve this?

Configure VLANs on the switch and use a Layer 3 switch to route between them

Keep all devices in one VLAN and use access control lists

Create two separate physical networks with two switches and no routing

Use a wireless access point to separate traffic

A technician is troubleshooting a PC that cannot reach a server on a different subnet. The PC's IP is 192.168.1.50/24 and the server's IP is 192.168.2.10/24. The PC can ping its own default gateway. What is the most likely reason the PC cannot reach the server?

The PC's default gateway is not configured or is unreachable

The server is on a different subnet, so the PC must send the packet to its default gateway, which may not have a route to 192.168.2.0/24

The PC's ARP cache is full and cannot resolve the server's MAC address

The server's subnet mask is incorrect
