Your network contains an Active Directory domain

named contoso.com. The domain contains a DHCP server

named Server1 that runs Windows Server 2012 R2.

You create a DHCP scope named Scope1. The scope has a start address of 192.168.1.10, an end address of 192.168.1.50, and a subnet mask of 255.255.255.192

.

You need to ensure that Scope1 has a subnet mask of 255.255.255.0.

What should you do first?

A. From the DHCP console, reconcile Scope1.

B. From the DHCP console, delete Scope1.

C. From the DHCP console, modify the Scope Options of Scope1.

D. From

Windows PowerShell, run the

Set-DhcpServerv4Scope

cmdlet.

Explanation:

You cannot change the subnet mask of a DHCP scope without deleting the scope and recreating it with the new subnet mask.

Incorrect Answers:

D: Set-DhcpServerv4Scope does not

include a parameter for the subnet mask.

Your network contains an Active Directory domain n

amed contoso.com. The domain contains a member server named Server1. Server1 runs Windows Server 2012 R2 and has the Hyper-V server role installed.

You create an external virtual switch named Switch1. Switch1 has the following configurations:

Connection t

ype: External network

Single-root I/O virtualization (SR-IOV): Enabled

Ten virtual machines connect to Switch1.

You need to ensure that all of the virtual machines that connect to Switch1 are isolated from the external network and can connect to each other

only. The solution must minimize network downtime for the virtual machines.

What should you do?

A. Remove Switch1 and recreate Switch1 as an internal network.

B. Change the Connection type of Switch1 to Private network.

C. Change the Connection type of Sw

itch1 to Internal network.

D. Remove Switch1 and recreate Switch1 as a private network.

Explanation:

You cannot change the type of vswitch from external to private when SR-IOV is enabled at vswitch creation ->you need to recreate the vswitch.
