Explanation
The best way to facilitate the effective execution of an incident response plan is to ensure that the response team is trained on the plan. An incident response plan is a set of instructions that defines the roles, responsibilities, procedures, and tools for detecting, responding to, and recovering from security incidents. An incident response team is a group of individuals that are assigned to perform specific tasks and activities during an incident response process. The response team may include security analysts, IT staff, legal counsel, public relations, and other stakeholders. To execute an incident response plan effectively, the response team needs to be trained on the plan, which means they need to be familiar with the following aspects of the plan:
The scope and objectives of the plan The roles and responsibilities of each team member The communication and escalation protocols The incident classification and prioritization criteria The incident response procedures and tools The incident documentation and reporting requirements The incident review and improvement processes By training the response team on the plan, the organization can ensure that the team members are prepared and confident to handle any security incidents that may occur, and that they can perform their tasks efficiently and consistently. The other options are not the best way to facilitate the effective execution of an incident response plan, although they may be some steps or outcomes of the process. The plan being based on risk assessment results is a desirable practice, as it ensures that the plan is aligned with the organization's risk profile and addresses the most relevant and likely threats and vulnerabilities. However, it does not guarantee that the plan will be executed effectively unless the response team is trained on the plan. The plan being based on industry best practice is a desirable practice, as it ensures that the plan follows established standards and guidelines for incident response. However, it does not guarantee that the plan will be executed effectively unless the response team is trained on the plan. The incident response plan aligning with the IT disaster recovery plan (DRP) is a desirable practice, as it ensures that the plans are consistent and coordinated in terms of objectives, scope, roles, procedures, and tools. However, it does not guarantee that the plan will be executed effectively unless the response team is trained on the plan

A web server should normally be placed within a demilitarized zone (DMZ) to shield the internal network. Database and file/print servers may contain confidential or valuable data and should always be placed on the internal network, never on a DMZ that is subject to compromise. Switches may bridge a DMZ to another network but do not technically reside within the DMZ network segment.
