Most networks have some supporting services to ensure users don’t need to configure their laptop, mobile, or workstation to get access to corporate resources or the internet. Dynamic Host Configuration Protocol (DHCP) helps users connect to a network by assigning them an IP address and several other settings. The Domain Name System (DNS) allows them to visit websites with a friendly name. Rather than needing to stand up a server at each location, we will be configuring the firewall to provide these services.
High-availability clustering and virtualization make deployments more resilient to failure and ensure that businesses can go on, even if something breaks. We will be setting up High Availability and reviewing implications for using both Active/Passive mode and Active/Active mode. We will also take a deeper look at using virtual systems on a chassis to logically split up network segments.
In this chapter, we’re going to cover...
