Which of the following benefits apply only to creating VLANs with switches and not to segmenting the network with regular switches? - You can create multiple collision domains. - You can create multiple broadcast domains. - You can provide guaranteed bandwidth between two devices. - You can segment the network based on physical location.

You can create multiple broadcast domains.

You are implementing a DHCP server for your segment. Your segment's IP address is 192.168.1.0. Your default gateway address is 192.168.1.254. Your DNS server address is 192.168.1.1. Your default gateway is configured as a NAT router to translate addresses between network segments. You configured the 03 Router option on your DHCP server so it can deliver the IP address of the default gateway to workstations. After configuring your workstations to get their IP addressing information dynamically, your users complain that they are unable to access websites on the internet. How can you resolve this problem?

You must configure your DHCP server with an option that delivers the IP address of the DNS server (Option 06).
