Government agencies currently operate their own websites, each with its own directory services. There is a mandate to minimize IT administration. Which of the following should the cloud services archi

Setting up a direct VPN tunnel between sites addresses network connectivity but does not resolve the administrative burden of managing separate, disparate directory services for user authentication and authorization.

Upgrading systems to use mobile technologies is about user access methods or application design, not directly about reducing the administrative overhead of managing separate directory services.

Upgrading operating systems on web servers is a maintenance task that does not inherently address or reduce the administrative complexity arising from managing multiple, independent directory services.

With each agency having its own directory services, centralizing or federating the identification and authorization process would significantly reduce IT administration overhead. This reengineering could involve implementing a single sign-on (SSO) solution or a shared identity provider, simplifying user management and access control across all websites and minimizing redundant administrative tasks.
