A network administrator is asked to divide the 192.168.10.0/24 subnet into four equal-sized subnets for four departments. Each department must have enough addresses for at least 50 hosts. Which subnet mask and address range should be used for the first department?

255.255.255.192, 192.168.10.0/26

255.255.255.224, 192.168.10.0/27

255.255.255.128, 192.168.10.0/25

A company has a web server that must be publicly accessible, but management is concerned about exposing the internal network. The server also needs to communicate with an internal database server that should not be reachable from the internet. Which architecture best meets these requirements?

Place both servers in the DMZ with public IP addresses.

Place both servers on the internal network and use port forwarding for the web server.

Place the web server in a DMZ with a public IP, and place the database server on the internal network with a private IP, allowing only the web server to reach the database.

Use NAT to give the database server a public IP address and rely on the firewall to block inbound traffic.

A company wants to isolate its finance department from the rest of the network to reduce the risk of lateral movement if a workstation is compromised. The network uses the 10.0.0.0/8 private address space. The finance department has 50 employees, each with one wired device. Which addressing scheme best meets the requirement?

Place finance devices on the same subnet but enable port security on the switch to limit MAC addresses.

Assign finance devices IP addresses from the same /24 subnet as other departments but with a different VLAN.

Create a separate /26 subnet for finance and use a router or Layer 3 switch to control traffic between subnets.

Use a /16 subnet for finance to allow for future growth and rely on the subnet mask to provide security.

A network technician is assigning IP addresses to devices in a new office. The office has been allocated the 192.168.1.0/24 network. The technician needs to create two subnets: one for 100 hosts and one for 50 hosts. Which subnet masks should be used?

/25 for the 100-host subnet and /26 for the 50-host subnet

/24 for the 100-host subnet and /25 for the 50-host subnet

/26 for the 100-host subnet and /27 for the 50-host subnet
