The answer should be NO here and the 3rd question answer should be Yes in this set. Deploying one VM with PIP does not solve anything as the monitoring solution is on a different vnet and it needs access to all the VMs in this vnet, whereas if all the VMs have PIPs then that monitoring solution will have access to all of them and the requirement will be met.

In general, Azure scale set virtual machines do not require their own public IP addresses. For most scenarios, it is more economical and secure to associate a public IP address to a load balancer or to an individual virtual machine (aka a jumpbox), which then routes incoming connections to scale set virtual machines as needed (for example, through inbound NAT rules).

It doesnt make sens.You setup scale set with private ip and six machines (to be isolated and get HA) and then you put it behind single VM with public IP? Absolutly no. Use Insights from Azure Monitor and Log Analitics agents to do monitoring. Also get Application Gateway\FrontDoor to provide public access to app on VMs in Scale Set.

Question is not really clear, I presume here the VM with the public IP will also run the Log Analytics Gateway and the Monitoring solution is Azure Monitor (through Log Analytics). In this scenario then Yes the answer is correct. https://docs.microsoft.com/en-us/azure/azure-monitor/agents/gateway

VM with public IP should server the job. As public IP or routable IP is needed to allow "public access" . Hence answer should be A

If you do nothing but add a VM with a public IP, how would the monitoring solution be able to access 'all the (other) VMs'? (There is nothing mentioned that you would install a gateway on that VM or something else.)

A is correct answer. Azure Monitor for VMs stores its data in Azure Monitor Logs, which allows it to deliver powerful aggregation and filtering and to analyze data trends over time. You can view this data in a single VM from the virtual machine directly, or you can use Azure Monitor to deliver an aggregated view of multiple VMs.

Correct anser is no, Use Virtual machine scale set insights from Azure Monitor. Install Log Analytics agent on the virtual machine scale set. https://azure.microsoft.com/en-us/blog/virtual-machine-scale-set-insights-from-azure-monitor/ https://docs.microsoft.com/en-us/azure/azure-monitor/insights/vminsights-enable-overview#supported-operating-systems

This is valid if Bastion is used which is not specified in the question.

But per the question you do not configure 'the new machine as a jump server'. You just install a VM with a public IP. That ALONE does surely not solve the problem.
