Which of the following are valid reasons for using an emulated network adapter rather
than a synthetic one? (Choose all that apply.)
- A.You want to install the guest OS by using a Windows Deployment Services server.
- B.There is no Guest Integration Services package available for the guest OS you plan to use.
- C.The manufacturer of your physical network adapter has not yet provided a synthetic network adapter driver.
- D.The emulated network adapter provides better performance.
- Answer & Explanation

Answer : [A, B]
Explanation :
Explanation :
| A. Correct: A Windows Deployment Server installation requires the network adapter to support PXE, which emulated adapters do, but synthetic adapters do not. B. Correct: Synthetic adapter drivers are installed as part of the Guest Integration Services package; if there is no package for the guest OS, then there are no synthetic drivers. C. Incorrect: Synthetic adapter drivers are not provided by hardware manufacturers. D. Incorrect: Synthetic adapters provide better performance than emulated adapters. |

Which of the following statements is not true about synthetic network adapters?
- A.Synthetic adapters communicate with the parent partition by using the VMBus.
- B.Synthetic adapters require the Guest Integration Services package to be installed on the guest OS.
- C.Synthetic adapters provide faster performance than emulated adapters.
- D.Synthetic adapters can start the child VM by using a PXE network boot.

Answer : [D]
Explanation :
Explanation :

A. Incorrect: Synthetic adapters use the faster VMBus for communications with the
parent partition; emulated adapters must use calls to the hypervisor. B. Incorrect: Synthetic adapter drivers are installed as part of the Guest Integration Services package on the guest OS. C. Incorrect: Because of their more efficient communication with the parent partition, synthetic adapters perform better than emulated adapters. D. Correct: Synthetic network adapters load with the Guest Integration Services on the guest OS, which prevents them from supporting PXE. |

How many dynamically assigned MAC addresses can a Hyper-V server provide by default?
- A.8
- B.256
- C.4,096
- D.Unlimited
- Answer & Explanation
- Report
Answer : [B]
Explanation :
Explanation :
|
A. Incorrect: A pool of eight MAC addresses would be insufficient for many Hyper-V
installations. B. Correct: A Hyper-V server provides a pool of 256 MAC addresses by default. You can create more by modifying the default address range. C. Incorrect: Hyper-V, by default, dedicates only one byte of the MAC address to a dynamic value, which is not enough to support 4,096 addresses. D. Incorrect: Hyper-V creates a finite pool of MAC addresses by specifying minimum and maximum address values. |
