To make use of IEEE 802.1 X when connecting a camera to the network, you need (Choose two)
Answer : A, C
To utilize IEEE 802.1X for connecting a camera to the network, the following are required:
A. An Ethernet switch with support for IEEE 802.1X, which ensures that only authorized devices can connect to the network.
C. A RADIUS server, which is used to manage authentication, authorization, and accounting (AAA) for network access control.
These components are essential for setting up secure network access using IEEE 802.1X.
Question 2
Which three are types of field of view?
Answer : B
The three types of field of view are telephoto, wide-angle, and normal. A wide-angle lens provides a broader view, a normal lens offers a standard view comparable to the human eye, and a telephoto lens allows for a narrower field of view with greater magnification. Axis Communications' technical resources detail these field of view options for different camera lenses.
Question 3
which describes an opportunistic attack?
Answer : B
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.
Question 4
Accelerometers are required for which feature?
Answer : B
Accelerometers are used in Axis cameras primarily for shock detection. They detect sudden movements or impacts that might indicate tampering or vandalism. When a shock is detected, the camera can trigger alerts or initiate protective actions to safeguard the device and maintain surveillance integrity. Axis technical specifications detail the use of accelerometers in various models for enhanced security through shock detection.
Question 5
A customer wants to minimize the risk of loosing recordings if there is a disconnect between the camera and the server. What is recommended?
Answer : B
To minimize the risk of losing recordings if there is a disconnect between the camera and the server, failover recordings are recommended. This involves having a secondary recording location, such as an SD card in the camera, that can store video footage temporarily until the connection to the server is restored. This ensures continuous recording and prevents data loss. Axis Communications' documentation on system reliability and failover solutions supports this recommendation.
Question 6
What protocol on layer 3 enables network traffic?
Answer : A
On layer 3 of the OSI model, the protocol that enables network traffic is IP (Internet Protocol). IP is responsible for addressing and routing packets of data so that they can travel across networks and reach the correct destination. It provides logical addressing and handles the path through which data is transferred between source and destination nodes. Axis documentation confirms that IP is crucial for network communication and is fundamental for the operation of network video systems.
Question 7
A P-iris lens is
Answer : C
A P-iris lens is a type of DC-iris lens that incorporates feedback to maintain optimal image quality. Unlike a standard DC-iris, which only adjusts based on light levels, a P-iris lens uses a feedback mechanism to optimize the iris position, ensuring consistent image sharpness, depth of field, and optimal contrast. This technology allows for precise control over the iris, which is especially beneficial in varying lighting conditions. According to Axis documentation, P-iris lenses are designed to deliver better performance by continuously adjusting the iris for optimal image quality.
