Secure Shell (SSH) is a protocol used for secure command-line access to remote systems, while Secure File Transfer Protocol (SFTP) is an extension of SSH used specifically for securely transferring files. Both SSH and SFTP ensure that data is encrypted during transmission, protecting it from interception or tampering.

Ensuring that other team members understand how a script works is essential to prevent a single point of failure. If only one person knows how the script operates, the organization risks being unable to maintain or troubleshoot it if that person is unavailable. Sharing knowledge ensures continuity and reduces dependence on one individual.
* Reducing implementation cost and remediating technical debt are secondary considerations in this context.
* Identifying complexity is important, but the main benefit is to avoid a single point of failure.

Comprehensive and Detailed Explanation From Exact Extract:
A playbook is a step-by-step, just-in-time reference used by Security Operations Center (SOC) analysts when responding to security alerts, incidents, and suspicious activities. Playbooks provide documented procedures for common scenarios such as malware detection, phishing investigations, ransomware response, and account compromise.
According to the CompTIA Security+ SY0-701 exam framework, playbooks support incident response by reducing analyst guesswork and ensuring consistency. They include details such as triage steps, required tools, escalation paths, log sources, and containment actions. This makes playbooks the most suitable document for immediate reference during live investigations.
Change management policies (A) govern system or configuration changes, not SOC operations. Risk profiles (B) provide organizational risk overviews, not incident-response steps. SIEM profiles (D) define correlation rules or dashboards but are not procedural guides.
Therefore, the correct answer is playbooks, which enable efficient, standardized, and repeatable responses to operational security events.

Mobile Device Management (MDM) allows administrators to configure, update, monitor, and push applications or features to company-provided mobile devices remotely and quickly. The requirement to restore missing features within 48 hours means IT needs centralized control and fast deployment-capabilities MDM provides.
With MDM, IT can:
* Push required apps
* Reconfigure devices
* Enforce security policies
* Restore missing features
* Update OS and settings remotely
COPE (B) relates to ownership and usage policy, not configuration management. EDR (A) protects against malware but cannot restore missing productivity features. FDE (D) encrypts storage and is unrelated to application availability.
MDM is the only option allowing rapid, centralized remediation.
Thus, C is correct.
