Bollards are physical barriers designed to prevent vehicles from ramming into or breaching secure facilities. They are often placed at entrances, around perimeters, or in front of critical infrastructure like data centers.

Locks, cameras, and fences provide important physical security, but they cannot stop a high-speed vehicle from causing damage. Cameras record activity, fences create boundaries, and locks secure access points, but only bollards physically block or mitigate vehicle attacks.

Governmental and critical infrastructure sites commonly deploy bollards to protect against both accidental collisions and deliberate vehicle-borne attacks. Combined with layered security measures—such as surveillance and fencing—they enhance resilience against physical threats to sensitive data centers.

The Domain Name System (DNS) is the cloud infrastructure component that employs a hierarchical and distributed database containing mappings. Managing Cloud documentation explains that DNS maps human-readable domain names to IP addresses and other resource records.

DNS is structured hierarchically, starting from the root level and branching into top-level domains, second-level domains, and subdomains. This distributed architecture ensures scalability, fault tolerance, and efficient resolution of requests across the internet and cloud environments.

TLS secures communications, clustered hosting refers to compute architecture, and resource sharing describes cloud efficiency. Therefore, DNS is the correct answer.

Patch management is a core process implemented during the hardening of an operating system and its workloads. Managing Cloud principles explain that OS hardening involves reducing vulnerabilities by applying security patches, updates, and fixes to eliminate known weaknesses.

Patch management ensures that operating systems, applications, and dependencies are kept up to date with vendor-released security patches. This process reduces the attack surface and prevents exploitation of known vulnerabilities. Effective patch management includes testing, deployment, verification, and ongoing monitoring.

Change management governs how changes are approved, incident management handles security events, and security management is a broader governance function. Therefore, patch management is the correct process associated with OS hardening.

The Data Controller is the role responsible for ensuring that third parties implement adequate technical and organizational security measures to protect data. Managing Cloud principles emphasize that the data controller determines the purpose and means of data processing and remains accountable for how personal or sensitive data is handled, even when third parties are involved.

When data is processed by cloud providers or other external entities, the data controller must ensure that contractual agreements, policies, and controls are in place to maintain data protection standards. This includes verifying that third parties follow approved security practices, comply with legal requirements, and apply appropriate safeguards.

Other roles do not carry this responsibility. A cloud user consumes cloud services but does not define processing requirements. A cloud provider implements security controls but acts under the instructions of the data controller. A data subject is the individual whose data is being processed and has no responsibility for security enforcement. Therefore, the data controller is the correct role.
