Explanation
A walk-through of the disaster recovery plan (DRP) is a method of testing the plan by simulating a disaster scenario and having the participants review their roles and responsibilities, as well as the procedures and resources required to execute the plan. A walk-through has the greatest positive impact on the ability to execute the DRP, as it helps to identify and resolve any gaps, errors, or inconsistencies in the plan, as well as to enhance the awareness and readiness of the stakeholders involved in the recovery process.

Explanation:
One of the main problems with using SNMP vl and v°2 is the clear text "community string" that it uses to authenticate. It is easy to sniff and reuse. Most times, the SNMP community string is shared throughout the organization's servers and routers, making this authentication problem a serious threat to security. There have been some isolated cases of remote buffer overflows against SNMP daemons, but generally that is not a problem. Cross site scripting is a web application vulnerability that is not related to SNMP. A man-in-the-middle attack against a user datagram protocol (UDP) makes no sense since there is no active session; every request has the community string and is answered independently.

Explanation:
To be successful in implementing restrictive password policies, it is necessary to obtain the buy-in of the end users. The best way to accomplish this is through a security awareness program. Regular password audits and penalties for noncompliance would not be as effective on their own; people would go around them unless forced by the system. Single sign-on is a technology solution that would enforce password complexity but would not promote user compliance. For the effort to be more effective, user buy-in is important.
