A user is trying to play a DVD on a projector. The user can hear the audio; however, the projector is showing an error message that states:
HDMI Blocked due to Copy Protection
Which of the following is the MOST likely cause of the error?
Correct Answer: C
The error message 'HDMI Blocked due to Copy Protection' is most likely caused by the projector not supporting the necessary HDCP (High-bandwidth Digital Content Protection) protocol. HDCP is designed to prevent unauthorized copying of digital content as it travels across connections such as HDMI. If the projector does not support HDCP, it cannot properly display the protected content from the DVD player, resulting in the error message. Therefore, the correct answer is that the projector does not support the necessary HDCP protocol.
While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is extremely polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel.
Which of the following is the MOST likely reason for this issue?
Correct Answer: A
The most likely reason the technician cannot select the channel with almost no RF pollution is that the channel is reserved for licensed band use. Licensed channels are designated for specific uses, often by regulated entities such as government agencies or telecommunications providers, and require special permission or licenses for access. Non-carrier-grade devices typically do not have the authorization to operate on these licensed channels, which explains why the technician is unable to select that otherwise vacant channel.
A user submitted a support ticket that states all of the printouts from a laser printer appear to have double images imposed on them. A review of past printer support tickets shows that a maintenance kit has not been installed in more than a year. Which of the following printer consumables is MOST likely causing the issue?
Correct Answer: B
Double images on printouts, often referred to as ghosting, are commonly caused by issues with the transfer roller in laser printers. The transfer roller is responsible for transferring toner from the drum onto the paper. If the roller is dirty or worn out, it can result in improper toner transfer, leading to residual images being printed along with the new ones. Given that a maintenance kit has not been installed in over a year, it is likely that the transfer roller is the culprit, as it needs regular maintenance to function correctly.
A technician is configuring a workstation to be used as a VM host. After installing the necessary software, the technician is unable to create any VMs. Which of the following actions should be performed?
Correct Answer: B
When configuring a workstation to be used as a VM host, it is important to enable the necessary hardware virtualization features. One of the key components for modern virtualization is the Trusted Platform Module (TPM), which provides hardware-based security functions. Enabling TPM ensures that the system supports secure boot and hardware virtualization, which are often necessary for creating and running virtual machines. The other options, such as disabling the BIOS password, enabling multithreading, or enabling Fast Startup, do not directly address the inability to create VMs and are not relevant to this issue.
A user's computer is not receiving a network connection. The technician confirms that the connection seems to be down and looks for the user's port on the patch panel. The port and patch panel are not labeled. Which of the following network tools should the technician use to identify the port?
Correct Answer: C
A toner probe is the most appropriate tool for identifying the port in this situation. It is used to trace and identify cables by sending a tone through the cable, which can be detected with a probe at the other end. This would allow the technician to identify the correct port on the patch panel. A network tap, punchdown tool, or crimper would not be useful for locating the specific port connected to the user's computer.
