Mixed Deck — All CVSS Topics Flashcards

What common challenge do professionals face when applying Access Control & Identity Management principles?

Answer: Balancing theoretical best practices with practical constraints and real-world conditions

Professionals commonly face the challenge of adapting theoretical best practices in Access Control & Identity Management to the practical constraints and varying conditions encountered in real-world settings.

Which VMS feature allows operators to define rules that trigger alerts or recording changes when specific conditions are met in video feeds?

Answer: Event-based rules engine

An event-based rules engine in a VMS allows administrators to configure automated responses — such as sending alerts or changing recording modes — when defined conditions are detected.

In VMS terminology, what does 'PTZ preset' refer to?

Answer: A saved pan, tilt, and zoom position that a PTZ camera can move to automatically

A PTZ preset stores a specific pan, tilt, and zoom position so the camera can be commanded to move to that exact position instantly, enabling fast coverage of key areas.

What common challenge do professionals face when applying Cloud Computing & Virtualization principles?

Answer: Balancing theoretical best practices with practical constraints and real-world conditions

Professionals commonly face the challenge of adapting theoretical best practices in Cloud Computing & Virtualization to the practical constraints and varying conditions encountered in real-world settings.

What is the advantage of using 'multicast' streaming in a VMS deployment with many client workstations?

Answer: It reduces bandwidth by sending one stream that multiple clients receive simultaneously

Multicast transmits a single video stream that multiple VMS clients can receive simultaneously, significantly reducing network bandwidth compared to multiple unicast streams.

In VMS licensing, what is typically meant by a 'channel license'?

Answer: A license that authorizes one camera or video input to be managed by the VMS

A channel license grants the VMS the right to manage a single camera or video source, and adding cameras typically requires purchasing additional channel licenses.

What organization develops safety standards for electrical equipment?

Answer: NEMA

NEMA (National Electrical Manufacturers Association) is the organization that develops safety standards for a wide range of electrical equipment, including components used in video systems. These standards ensure the safety, performance, and interoperability of electrical products, contributing to reliable and compliant system installations.

Which best describes the scope of Vulnerability Assessment & Penetration Testing in professional practice?

Answer: A comprehensive area covering both theoretical foundations and practical applications

Vulnerability Assessment & Penetration Testing encompasses both theoretical foundations and practical applications that are essential to professional practice in this field.

What is the purpose of a VMS 'bookmark' feature during video playback?

Answer: Mark specific moments in recorded video for quick future retrieval

Bookmarks allow operators or investigators to tag specific timestamps in recorded video so those moments can be quickly located and reviewed later.

In a multi-megapixel camera system, what trade-off must a designer consider when increasing resolution?

Answer: Higher resolution requires more bandwidth and storage

Megapixel cameras produce larger image files, which directly increases bandwidth consumption and storage capacity requirements.

What is 'back focal length' (BFL) adjustment critical for when installing a CS-mount lens on a C-mount camera body?

Answer: Ensuring the focal plane aligns with the sensor surface for proper focus

The 5mm difference between C-mount and CS-mount requires a C-ring adapter or BFL adjustment to bring the focal plane onto the sensor correctly.

What is the purpose of compression in video processing?

Answer: To reduce data size

Video compression is a vital process that reduces the amount of data required to represent a video signal. This is achieved by removing redundant or less important information, allowing for more efficient storage and transmission of video files. Compression is essential for streaming video, digital broadcasting, and storing large video libraries, as it conserves bandwidth and storage space.

When selecting a camera lens for license plate capture on a highway lane, which characteristic is most critical?

Answer: Long focal length for narrow field of view and subject magnification

A long focal length (telephoto) lens narrows the field of view and magnifies distant subjects, which is essential for capturing legible license plates from a distance.

How does Cloud Computing & Virtualization contribute to overall professional effectiveness?

Answer: It provides essential knowledge and skills that directly impact quality of work and outcomes

Cloud Computing & Virtualization directly contributes to professional effectiveness by providing essential knowledge and skills that improve the quality of work and outcomes across all career levels.

What does the term 'signal-to-noise ratio' (SNR) describe?

Answer: Ratio of signal to noise

Signal-to-noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. In video transmission, a higher SNR indicates a clearer signal with less interference, resulting in better picture quality. A low SNR means the noise is more prominent, degrading the video image.

What is the most important competency assessed in Vulnerability Assessment & Penetration Testing for professionals in this field?

Answer: Applied knowledge and practical problem-solving ability

Vulnerability Assessment & Penetration Testing assessment focuses on applied knowledge and practical problem-solving ability, ensuring professionals can effectively perform in real-world situations.

How can you prevent video signal interference in CCTV systems?

Answer: Properly grounding equipment and using shielded cables.

Preventing video signal interference in CCTV systems is best achieved by properly grounding equipment and using shielded cables. Proper grounding diverts stray electrical currents, while shielded cables protect the video signal from external electromagnetic interference, both critical for maintaining clear and stable video transmission.

What is required before video equipment can be sold in the US?

Answer: Compliance with standards

Before video equipment can be sold in the US, it is required to demonstrate compliance with various safety and performance standards. This often involves certification by recognized bodies like UL and adherence to regulations from agencies such as the FCC, ensuring the product is safe, reliable, and does not cause undue interference.

In video forensics, 'chain of custody' for recorded footage primarily requires:

Answer: Documenting who accessed, copied, or exported footage and maintaining its integrity

Chain of custody requires an auditable record of every person who handled the evidence and verification that the footage has not been altered since capture.

What is the recommended approach to staying current in Vulnerability Assessment & Penetration Testing?

Answer: Regular professional development, industry publications, and peer collaboration

Staying current in Vulnerability Assessment & Penetration Testing requires ongoing professional development, reading industry publications, and collaborating with peers to share knowledge and best practices.
