Comprehensive and Detailed Explanation From Exact Extract:

Video surveillance (A) provides continuous monitoring and allows for real-time, remote visibility of secure locations, such as computer rooms. When integrated with analytics, video surveillance systems can detect movement after hours or unauthorized access and generate immediate alerts. These systems also maintain video logs that can be audited later.

NFC access cards (B) allow controlled access to physical areas, generating time-stamped logs for each entry attempt. When connected to an access control system, these cards can trigger alerts for unauthorized access attempts, such as the use of expired credentials or access during restricted hours.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — Security Controls and Physical Security Section:

“Security access systems using NFC or smart cards allow traceability of personnel entry through electronic logs, while surveillance systems provide visibility and support forensic investigations.”

“Video surveillance allows real-time monitoring of physical environments and helps detect unauthorized presence or access in sensitive locations.”

Comprehensive and Detailed Explanation From Exact Extract:

Using an active-active deployment across two regions with at least two Availability Zones (AZs) each provides the highest level of fault tolerance and geographic redundancy. This ensures continuity even if an entire region or multiple zones become unavailable. In regulated sectors such as healthcare, this meets strict availability and disaster recovery requirements.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “High Availability and Multi-Region Design”:

“Active-active configurations across multiple regions and availability zones maximize uptime and ensure failover in the event of localized or regional failures.”

Other options:

B. Active-passive introduces delays in failover.

C. Active-active in one region offers no geographic redundancy.

D. Active-passive in two regions is slower and less efficient during failover.

Comprehensive and Detailed Explanation From Exact Extract:

A 403 Forbidden error indicates that the request was understood by the server but is refusing to fulfill it due to insufficient authorization. The developer is attempting to call a protected API that requires valid credentials such as an access key and signature (often used in HMAC-based APIs), but the values appear as Postman variables (e.g., {{rapyd_access_key}}), which suggests they were not replaced with actual credentials.

This typically means that the request lacks proper authentication or authorization headers, or the keys/signature are incorrect or missing. The presence of access_key, signature, salt, and timestamp in the request implies the API requires authentication, but the variables were not resolved or valid.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “API Security and Authentication”:

“A 403 error typically results from failed authentication or lack of proper authorization. Developers must ensure that tokens or signatures are valid, not missing, and properly injected.”

Other options:

A. 404 is the code for a missing resource, not 403.

C. A firewall rule would block the request entirely (e.g., no response or a 0 status), not result in a 403 from the server.

D. HTTP redirection issues typically result in 3xx codes, not 403.
