Your company has two offices. The offices are located in Seattle and Montreal.
The network contains an Active Directory domain named contoso.com. The domain contains two
DHCP servers named Server1 and Server2. Server1 is located in the Seattle office. Server2 is located
in the Montreal office. All servers run Windows Server 2012 R2.
You need to create a DHCP scope for video conferencing in the Montreal office. The scope must be
configured as shown in the following table.
Which Windows PowerShell cmdlet should you run?
A.
Add-DhcpServerv4SuperScope
B.
Add-DhcpServerv4MulticastScope
C.
Add-DHCPServerv4Policy
D.
Add-DchpServerv4Scope
Explanation:
The Add-DhcpServerv4MulticastScope cmdlet adds a multicast scope on the Dynamic Host
Configuration Protocol (DHCP) server.
Note: IPv4 multicast addresses are defined by the leading address bits of 1110, originating from the
classful network design of the early Internet when this group of addresses was designated as Class D.
The Classless Inter-Domain Routing (CIDR) prefix of this group is 224.0.0.0/4. The group includes the
addresses from 224.0.0.0 to 239.255.255.255.Add-DhcpServerv4MulticastScope
i go with answer B but i also can video conference with a unicast transmission.
Multicast isn’t mandatory for videoconferencing…
stupid question.

IPs 224.0.0.0 through 239.255.255.255 are reserved for multicast addresses. Starting and ending IP address belong to that range.

Great blog! Do you have any hints for aspiring writers? I’m hoping to start my own blog soon but I’m a little lost on everything. Would you suggest starting with a free platform like WordPress or go for a paid option? There are so many options out there that I’m completely overwhelmed .. Any ideas? Kudos!|

At first I thought you can simply use Add-DHCPServer4Scope. However, the key in this is paying attention to the scope IP range. The address begins with 224 which makes it a multicast, so the correct answer is Add-DHCPServer4MulticastScope
