* Confidentiality with Data at Rest: Confidentiality is a core principle of data security, ensuring that data stored (at rest) is only accessible to authorized individuals. This protection is achieved through mechanisms such as encryption, access controls, and permissions.
* Privileged Access: The statement "Data can be accessed after privileged access is granted" aligns with the confidentiality principle, as it restricts data access to users who have been granted specific permissions or roles. Only those with the appropriate credentials or permissions can access the data.
* Incorrect Options:
* A. "Data can be accessed by anyone on the administrative network." This violates the principle of confidentiality by allowing unrestricted access.
* B. "Data can be accessed remotely with proper training." This focuses on remote access rather than restricting access based on privileges.
* D. "Data can be accessed after verifying the hash." This option relates more to data integrity rather than confidentiality.

Comprehensive and Detailed In-Depth Explanation:
A Change Advisory Board (CAB) reviews and approves network changes. Before approval, they need a detailed action plan outlining the change, potential impacts, and mitigation strategies.
* A Plan of Action includes risk assessments, rollback procedures, and deployment steps, which are critical for decision-making.

MTTR (Mean Time to Repair) is the average time it takes to repair a system or service after a failure. It helps in measuring the downtime and planning recovery processes.

* Definition of GDPR:
* General Data Protection Regulation (GDPR) is a regulation in EU law on data protection and privacy for all individuals within the European Union and the European Economic Area. It also addresses the transfer of personal data outside the EU and EEA areas.
* Scope and Objectives:
* GDPR aims to give individuals control over their personal data and to simplify the regulatory environment for international business by unifying the regulation within the EU.
* It enforces rules about data protection, requiring companies to protect the personal data and privacy of EU citizens for transactions that occur within EU member states.
* Comparison with Other Options:
* SCADA (Supervisory Control and Data Acquisition): Refers to control systems used in industrial and infrastructure processes, not related to personal data protection.
* SAML (Security Assertion Markup Language): A standard for exchanging authentication and authorization data between parties, not specifically for personal data protection.
* PCI DSS (Payment Card Industry Data Security Standard): A set of security standards designed to ensure that all companies that accept, process, store or transmit credit card information maintain a secure environment, not specific to personal data protection in Europe.
* Key Provisions:
* GDPR includes provisions for data processing, data subject rights, obligations of data controllers and processors, and penalties for non-compliance.

An incorrect pinout on the patch cable could prevent network connectivity due to mismatched wiring. Even if the cables are the correct length and type, a pinout issue can cause continuity problems and prevent data transmission. Proper crimping with the correct pinout is essential for network cables to function. (Reference:
