Question 42
Which of the following causes the image to get black corners?
Options:
A.
WDR is disabled and image is overexposed
B.
The lens is intended for a smaller image sensor
C.
WDR is disabled and image is underexposed
D.
The lens is intended for a larger image sensor
Answer:
D
Explanation:
"When a lens intended for a larger sensor is used on a smaller sensor camera, the projected image circle does not fully cover the sensor area, causing vignetting or black corners in the image."
— Axis Lens Guide White Paper
"Black corners or vignetting often result from a mismatch between lens and sensor size."

Question 43
Which are the main benefits of OptimizedlR? (Select two)
Options:
A.
External IR illuminators can be used
B.
The IR light has a wavelength of 940 nm
C.
The beam of the IR follows the camera's field of view
D.
The images do not get overexposed
E.
Smooth transition between day and night mode
Answer:
C, D
Explanation:
OptimizedIR technology in Axis cameras adjusts the IR illumination to match the camera's field of view. This ensures that the IR light is evenly distributed across the scene, reducing the risk of overexposure and enhancing image quality. Furthermore, this alignment helps to maintain image clarity and detail by preventing hot spots and ensuring a balanced exposure across the entire frame. According to Axis documentation, these benefits help improve the effectiveness of night-time surveillance and reduce the need for additional external IR illuminators.
Question 44
which describes an opportunistic attack?
Options:
A.
Typically performed by a person with legitimate access
B.
The attacker is usually not acquainted with the target
C.
Often organized, with several people involved
D.
Targeted at a specific system with a specific goal
Answer:
B
Explanation:
An opportunistic attack is characterized by the attacker not being acquainted with the target. These attacks are typically random and take advantage of any available vulnerability rather than being specifically targeted at a particular system or organization. The attacker usually seeks easy targets with known vulnerabilities and acts quickly when an opportunity arises. Axis security documentation describes opportunistic attacks as generally unsophisticated, focusing on exploiting common and readily available weaknesses in systems.
