About this chapter
What this chapter covers
This domain covers how Azure resources are connected, secured and reached. It makes up between 15 and 20 percent of the exam, and networking questions are often scenario puzzles, so it rewards understanding over memorising.
The topics are building virtual networks, peering and routing, securing access with network security groups, Azure Bastion, service endpoints and private endpoints, and name resolution and load balancing.
How the topics fit together
The pages move from the network itself, to who may use it, to how names and traffic find the right machine.
- Virtual networks, peering and routes covers address spaces, subnets, peering, public IP addresses, user defined routes and troubleshooting tools.
- NSGs, Bastion and private access covers security rules, application security groups, Azure Bastion, service endpoints and private endpoints.
- DNS and load balancing covers Azure DNS zones, records, load balancers and how to troubleshoot them.
When a connection fails, work in this order: the route, then the security rule, then the name, then the load balancer. Network Watcher has a tool for each.
How to use these pages
Each topic page has the same shape, so you can skim for what you need.
- What it is: the idea in plain words.
- How it works: the mechanism, with diagrams and tables.
- What to remember for the exam: the facts to memorise.
- Common mistakes: the classic traps.
- Check yourself: three questions to test your understanding.
