2-2-3 reading Douglas is setting up VM instances on a Hyper-V server to host some basic web server and legacy software workloads along with some light app testing. He needs to know how many vCPUs to allocate to each VM. The server's motherboard has two CPU sockets, both populated with 8-core processors, and hyperthreading is enabled. He's decided that the VMs' workloads can easily handle a 3:1 overcommitment ratio. He plans on creating 15 VMs at first and eventually increasing to 25 VMs as he fine-tunes the workloads and resource allocations.

1-5-2 reading Anika has run into a problem with the VPN connection to her company's cloud-hosted database. She has a good Internet connection and can access her work email account, which uses the same sign-in credentials as the VPN. But she still can't pull reports from the database service. She calls Patrick, who works for the company's help desk. As Anika describes the problem to Patrick, he tells her to try again and make sure she's using the right password, then restart her router, and if that still doesn't fix it, to restart her computer.

4-3-6 reading Tim is troubleshooting a problem with his VM in AWS. He created a new VPC and a new subnet, enabled auto-assign public IPs, added an IG and a VM, and attached the VM's interface to a subnet within the VPC. This is where he ran into problems. Tim has been trying for 30 minutes to open an RDP connection to the VM and it's not working. He confirmed the VM is set to allow RDP traffic, and the VPC and subnet both also allow RDP traffic. He also confirmed the VM is running.

He should configure a route to the IG

3-3-1 reading Mykel and his team recently completed a major migration of several business-critical applications to AWS's public cloud, and they're performing some final tests before going live. While taking a short break at a nearby coffee shop, Mykel decided to remote into one of the primary servers from his personal laptop so he could make some additional configuration changes. As he's completing the changes, it occurs to him that this particular server is supposed to be locked down to provide access only from his computer back at his desk. He pokes around in the account to see how much access he has with this user account and then returns to the office to address the problem.
