Your network contains servers that run Windows Server 2008 R2 and client computers that run Windows 7.
All network routers support IPsec connections. Client computers and servers use IPsec to connect through network routers.
You have two servers named Server1 and Server2. Server1 has Active Directory Certificate Services (AD CS) installed and is configured as a certification authority (CA). Server2 runs Internet Information Services (IIS).
You need to recommend a certificate solution for the network routers. The solution must meet the following requirements:
Use the Simple Certificate Enrollment Protocol (SCEP).
Enable the routers to automatically request certificates.
What should you recommend implementing?
A. Certification authority Web enrollment services on Server2
B. Network Device Enrollment Service on Server2
C. Online Responder service on Server1
D. Subordinate CA on Server1
