You need to recommend a communication solution that meets the following requirements…

Your network contains a System Center 2012 Configuration Manager environment. The
environment contains a single primary site. The primary site has a distribution point and a
management point.
You need to recommend a communication solution that meets the following requirements:
Communication between the client computers in the research department and the
management point must use HTTPS.
Communication between all of the other client computers and the management point must
be able to use HTTP.
Minimize the number of site systems.
What should you do?

A.
Configure the existing management point to use HTTPS. Configure the research
department computers always to use HTTPS.

B.
Install a new management point and configure the management point always to use
HTTPS. Configure the research department computers always to use HTTPS.

C.
Create a new primary child site and configure the site to use native mode. Assign all of
the research department computers to the new site.

D.
Install a new management point and configure Windows Firewall to block inbound TCP
port 80. Configure the research department computers always to use HTTPS.

Explanation:
You can have one management point that accepts HTTPS client communication and
another management point that accepts HTTP client communication.
Note:
To communicate with a site system role, the client must first locate a site system support the
protocol (HTTPS or HTTP) that the client can use. By default, clients use the most secure

method available to them. Using HTTPS before it communicates with a site system role that
uses HTTP.
When you deploy a site system role include management points, an Application Catalog
website point, a state migration point, or distribution points, you must specify whether clients
connect to the site system by using HTTP or HTTPS. If you use HTTP, you must also
consider signing and encryption choices.
In a single site, you can have one management point that accepts HTTPS client
communication and another management point that accepts HTTP client communication.
You can use one site to manage clients across different network locations that use different
communication protocols and security settings.

Other client computers can be configured for Internet and intranet client management.
They can automatically switch between Internet-based client management and intranet client
management when they detect a change of network. If these clients can find and connect to
a management point that is configured for client connections on the intranet, they attempt to
connect to an Internet-based management point.
