A small business uses a single firewall to connect its internal network to the internet. The owner wants to allow remote employees to securely access internal resources. Which combination of technologies provides both authentication and confidentiality for remote access?

A site-to-site VPN that terminates at the firewall but does not require user authentication.

VPN with IPsec and digital certificates for user authentication.

A remote desktop gateway that uses only username and password authentication.

Port forwarding on the firewall to allow direct RDP access to internal desktops.

A branch office has 200 employees, each with a desktop and a VoIP phone. The network administrator allocated a single /24 subnet for the entire office. Employees report that call quality degrades during peak hours and file transfers are slow. The administrator suspects broadcast overhead and collisions are contributing. Which change would most directly reduce broadcast domain size and improve overall performance?

Create separate VLANs for data and VoIP, each with its own subnet, and route between them.

Upgrade all switches to gigabit ports and enable jumbo frames on the access layer.

Disable DHCP and assign static IP addresses to every device to eliminate broadcast traffic.

Replace the existing switches with higher-port-density switches and use a single VLAN for all devices.

What is the primary function of DNS?

To translate domain names into IP addresses

To route packets between networks

To assign IP addresses to devices

A hospital deploys wireless access points for staff tablets. The security policy requires that only authorized devices can join the network and that all wireless traffic is encrypted. Which configuration should be used?

Open network with a captive portal

WPA2-Personal with a shared passphrase

WPA2-Enterprise with 802.1X authentication
