A network administrator is reviewing a routing table and sees the entry 172.16.0.0/20. The administrator needs to determine the equivalent subnet mask and the number of usable host addresses per subnet. Which pair is correct?

255.255.248.0 and 2046 usable hosts

255.255.224.0 and 8190 usable hosts

255.255.255.0 and 254 usable hosts

255.255.240.0 and 4094 usable hosts

A network engineer is troubleshooting intermittent connectivity issues. The network uses a single /24 subnet with 200 devices. The engineer suspects broadcast storms are causing the issue. The engineer decides to split the network into two /25 subnets. What is the expected effect on broadcast traffic?

Broadcast traffic increases because there are now two subnets generating broadcasts.

Broadcast traffic is eliminated because /25 subnets do not support broadcasts.

Broadcast traffic remains the same because the total number of devices is unchanged.

Broadcast traffic is reduced because each subnet is a separate broadcast domain, so broadcasts only reach 100 devices instead of 200.

A small company has a single flat network with 200 devices. The network experiences excessive broadcast traffic, and the administrator wants to reduce the size of the broadcast domain without changing the IP addressing scheme's overall structure. The company uses the 192.168.1.0/24 network. Which action will most effectively reduce the broadcast domain size?

Implement VLANs but keep the same /24 subnet for all VLANs.

Increase the subnet mask to /16 to allow more hosts.

Divide the /24 network into multiple /26 subnets and route between them.

Replace all hubs with switches.
