@KL, I have used this same set of questions from examstopic and passed my exam. The questions are valid. But you can get 50% of the questions free here and if you want to buy the full version I suggest you buy it form here as they offer you 50% discount where you can buy 2 exam for $68. This is way much cheaper than exam topics.

Correct Sequence for Q284 is Create a Log Analytics workspace This is the central store for logs and metrics collected by Azure Monitor. Create an Application Insights resource Application Insights collects application-level logs and telemetry and integrates with Azure Monitor (and the Log Analytics workspace). Add a VMInsights solution VM Insights uses the Log Analytics workspace to collect performance and dependency data from the VMs. Install agents on the VM and VM scale set to be monitored The Azure Monitor agent (or legacy agents) must be installed to actually send data from the VMs to Azure Monitor.
