A small company has a flat network with all users and servers on the same subnet. The finance department handles sensitive data and management wants to isolate finance traffic from the rest of the company without purchasing new hardware. Which approach should the network administrator implement?

Create a separate VLAN for the finance department and configure the existing switch ports accordingly.

Use a hub for the finance department to create a separate collision domain.

Place the finance department behind a separate firewall appliance connected to the core switch.

Assign different IP subnets to finance and other users, but keep them on the same switch without VLANs.

A hospital network has a flat Layer 2 design. The security team wants to isolate the medical-device network from the general user network while keeping both on the same physical switches. They also need to ensure that broadcast traffic from the user network does not reach the medical devices. Which configuration should be implemented?

Use a hub for the medical devices and a switch for the user network to reduce broadcast exposure.

Place all devices in the same VLAN but use a firewall between the user and medical-device subnets.

Configure the medical-device ports as access ports in the user VLAN and rely on the router to filter traffic.

Create two separate VLANs and assign switch ports to the appropriate VLAN based on device type.

A company is designing a network for a new office with 50 workstations. They need high availability so that if one switch fails, the workstations can still communicate with each other. Which topology should they choose?

Ring topology with a single ring

Star topology with a single central switch

Mesh topology with redundant links between switches

Bus topology with a single backbone cable

Part of the Network Fundamentals and Architecture domain, which makes up ~26% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 180-minute exam (~70–120 total, ~18–31 in this domain), expect 9–16 from this objective — we provide 39 practice questions to prepare you well beyond it.

A network administrator is reviewing a packet capture and sees a source IP address of 10.10.10.5/24 sending traffic to 10.10.20.10/24. The administrator knows that the two subnets are on different VLANs. Which device must be involved for this traffic to reach its destination?
