Explanation:
There should be documented standards- procedures for the use of cryptography across the enterprise; they should define the circumstances where cryptography should be used. They should cover the selection of cryptographic algorithms and key lengths, but not define them precisely, and they should address the handling of cryptographic keys. However, this is secondary to how and when cryptography should be used.
The use of cryptographic solutions should be addressed but, again, this is a secondary consideration.

An intranet server should be placed on the internal network. Placing it on an external router leaves it defenseless. Since firewalls should be installed on hardened servers with minimal services enabled, it is inappropriate to store the intranet server on the same physical device as the firewall. Similarly, primary- domain controllers do not normally share the physical device as the intranet server.

Explanation:
Some patches can conflict with application code. For this reason, it is very important to first test all patches in a test environment to ensure that there are no conflicts with existing application systems. For this reason, choices C and D are incorrect as they advocate automatic updating. As for frequent server updates, this is an incomplete (vague) answer from the choices given.
