- A network engineer carves a subnet of 192.168.44.0/26 for a set of application servers in Azure. How many addresses can be assigned to resources in that subnet?Easy
- A team deploys VMs into a new subnet in a recently created VNet. The VMs must download patches from public repositories using a stable outbound IP, and nothing on the internet should be able to initiate connections to them. What is the best fit?Easy
- A jump host cannot open RDP (TCP 3389) to a VM in another subnet. You need to know which NSG rule, if any, allows or denies that exact flow, and you want a fast answer. Which Network Watcher tool should you run?Medium
- A team proposes attaching an Azure DDoS Network Protection plan directly to a Virtual WAN hub to protect branch-to-cloud traffic. How should you respond?Medium
- Workloads in several spoke VNets need answers for names kept on DNS servers in the corporate datacenter, and a central Azure resolver should enforce one policy. What should be deployed and configured?Medium
- A hub DNS Private Resolver has an inbound endpoint at 10.10.0.4. A ruleset forwards corp.example.net queries to that address, so spoke VNets can use the hub. Which of these VNets must be left unlinked from this ruleset?Hard
