Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
A company named Contoso, Ltd. has several servers that run Windows Server 2016. Contoso has a Hyper-V environment that uses failover clustering and
Windows Server Update Services (WSUS). The environment contains several Windows containers and several virtual machines.
The WSUS deployment contains one upstream server that is located on the company's perimeter network and several downstream servers located on the internal network. A firewall separates the upstream server from the downstream servers.
You plan to deploy a human resources application to a new server named HRServer5. HRServer5 contains a FAT32-formatted data volume.
The CIO of Contoso identifies the following requirements for the company's IT department:
Deploy a failover cluster to two new virtual machines.

✑ Store all application databases by using Encrypted File System (EFS).
✑ Ensure that each Windows container has a dedicated IP address assigned by a DHCP server.
✑ Produce a report that lists the processor time used by all of the processes on a server named Server1 for five hours.
✑ Encrypt all communication between the internal network and the perimeter network, including all WSUS communications.
✑ Automatically load balance the virtual machines hosted in the Hyper-V cluster when processor utilization exceeds 70 percent.
Which networking mode should you configure for the Windows containers?

  • A. 12tunnel
  • B. 12bridge
  • C. network address translation (NAT)
  • D. transparent
Show Suggested Answer Hide Answer
Suggested Answer: D 🗳️
From the scenario:
✑ Ensure that each Windows container has a dedicated IP address assigned by a DHCP server.
Transparent mode supports static or dynamic (using external DHCP server) IP allocation and assignment from IP addresses within container host's network prefix.
Incorrect Answers:
A: L2Tunnel mode is reserved for private and public cloud deployments when containers are running on a tenant VM.
B: L2Bridge mode only supports static IP assignment.
C: NAT is the default network mode and attaches containers to a private IP subnet. This mode supports dynamic IP allocation and assignment but by Host
Networking Service (HNS) from internal NAT subnet prefix.

NAT is the correct answer. Any thoughts?

NAT will never understand the DHCP traffic, so that's not possible
