Your company has a main office and 20 branch offices in North America and Europe. Each branch office connects to the main office by using a WAN link. All the offices connect to the Internet and resolve external host names by using the main office connections.
You plan to deploy Microsoft 365 and to implement a direct Internet connection in each office.
You need to recommend a change to the infrastructure to provide the quickest possible access to Microsoft 365 services.
What is the best recommendation to achieve the goal? More than one answer choice may achieve the goal. Select the BEST answer.
- A . For all the client computers in the branch offices, modify the MTU setting by using a Group Policy object (GPO).
B. In each branch office, deploy a proxy server that has user authentication enabled.
C. In each branch office, deploy a firewall that has packet inspection enabled.
D. In each branch office, configure name resolution so that all external hosts are redirected to public DNS
servers directly.
Suggested Answer: D
Explanation:
Being a cloud service, Office 365 would be classed as an external host to the office computers.
All the offices connect to the Internet and resolve external host names by using the main office connections. This means that all branch office computers perform DNS lookups and connect to the Internet over the WAN link.
Each branch office will have a direct connection to the Internet so the quickest possible access to Microsoft 365 services would be by using the direct Internet connections. However, the DNS lookups would still go over the WAN links to main office. The solution to provide the quickest possible access to Microsoft 365 services is to configure DNS name resolution so that the computers use public DNS servers for external hosts. That way DNS lookups for Office 365 and the connections to Office 365 will use the direct Internet connections.
