EC2 INSTANCE SET UP

Go to https://aws.amazon.com/ec2/pricing/on-demand/ and select Northern Virginia as the region, and 32 for vCPUs.

If the instance must be running Windows then you're out of luck. If you can somehow make use of Linux then you are able to get a c6g.8xlarge for $1.088 per hour, or a c7g.8xlarge for $1.16 per hour, both of these are 32 vCPU and 64GB memory. These are the only two instance that are suitably specced and within budget. Prices are before tax, and don't include any storage.

The c7g is build around Arm-based AWS Graviton3 processors, whereas c6g uses Graviton 2. You weill know whether this is worth an extra 7 cents per hour to you.

Northern Virginia and Ohio tend to be the cheapest regions for any resources, but there is no harm in searching other regions.

If the instance must be running Windows then as @Kallu has already said these start at more than double what you are willing to pay. You may be able to get closer to your price point if you purchase one-year or three-year Reserved Instances, depending on how well that fits with your CCNP study plans https://aws.amazon.com/ec2/pricing/reserved-instances/ (bear in mind these prices are best for an always-on system, so if you intend to stop your instance when you're not using it for study then RIs are probably going to work out more expensive in the long run).

I don't think you will be able to run VMware workstation on any of these, if you want an instance that will host a virtual machine there is more information about running Hyper-V on EC2 here https://aws.amazon.com/blogs/compute/running-hyper-v-on-amazon-ec2-bare-metal-instances/ but this is going to be way outside the budget you have set yousrself.
