Explanation

Box 1: No. VM4 is in Subnet13 which has NSG3 attached to it.
VM1 is in ASG1. NSG3 would only allow ICMP pings from ASG2 but not ASG1. Only TCP traffic is allowed from ASG1.
NSG3 has the inbound security rules shown in the following table.

Box 2: Yes.
VM2 is in ASG2. Any protocol is allowed from ASG2 so ICMP ping would be allowed.
Box3. VM1 is in ASG1. TCP traffic is allowed from ASG1 so VM1 could connect to the web server as connections to the web server would be on ports TCP 80 or TCP 443.

Explanation

Box 1: VNET4 and VNET1 only
RG1 has only Delete lock, while there are no locks on RG4.
RG2 and RG3 both have Read-only locks.
Box 2: VNET4 only
There are no locks on RG4, while the other resource groups have either Delete or Read-only locks.
Note: As an administrator, you may need to lock a subscription, resource group, or resource to prevent other users in your organization from accidentally deleting or modifying critical resources. You can set the lock level to CanNotDelete or ReadOnly. In the portal, the locks are called Delete and Read-only respectively.
* CanNotDelete means authorized users can still read and modify a resource, but they can't delete the resource.
* ReadOnly means authorized users can read a resource, but they can't delete or update the resource.
Applying this lock is similar to restricting all authorized users to the permissions granted by the Reader role.
Scenario:
User2 is a Security administrator.
Sub1 contains six resource groups named RG1, RG2, RG3, RG4, RG5, and RG6.
User2 creates the virtual networks shown in the following table.

Sub1 contains the locks shown in the following table.
