Which of the following cloud components can filter inbound and outbound traffic between cloud resources?
Correct Answer:
C
Network security groups are cloud components that can filter inbound and outbound traffic between cloud resources based on rules and priorities. Network security groups can be applied to virtual machines, subnets, or network interfaces to control the network access and security. Network security groups can allow or deny traffic based on the source, destination, port, and protocol of the packets. Network security groups are different from NAT gateways, service endpoints, and virtual private clouds, which are other cloud components that have different functions and purposes.

A network technician is reviewing the interface counters on a router interface. The technician is attempting to confirm a cable issue. Given the following information:
Which of the following metrics confirms there is a cabling issue?
Correct Answer:
C
CRC stands for Cyclic Redundancy Check, and it is a type of error-detecting code used to detect accidental changes to raw data. If the CRC count is increasing on a particular interface, it indicates that there might be an issue with the cabling, which is causing data corruption. References:

A support agent receives a report that a remote user's wired devices are constantly disconnecting and have slow speeds. Upon inspection, the support agent sees that the user's coaxial modem has a signal power of -97dB Which of the following should the support agent recommend to troubleshoot the issue?
Correct Answer:
A
A splitter is a device that divides a coaxial cable into two or more branches, allowing multiple devices to share the same cable connection. However, a splitter also reduces the signal strength and quality of the cable, which can affect the performance and reliability of the devices connected to it. A signal power of -97dB is very low and indicates a weak or poor cable signal, which can cause constant disconnections and slow speeds.
The support agent should recommend removing any splitters connected to the line and connecting the coaxial modem directly to the cable outlet. This can help to improve the signal power and quality of the cable, and thus enhance the performance and reliability of the wired devices. Alternatively, the support agent can also suggest using a signal amplifier or booster, which is a device that increases the signal strength and quality of the cable, to compensate for the signal loss caused by the splitter.
The other options are not correct because they are not the best recommendations to troubleshoot the issue. They are:
✑ Switching the devices to wireless. Switching the devices to wireless may not solve
the issue, as the wireless connection may also depend on the cable signal and quality. Moreover, switching the devices to wireless may introduce other problems, such as interference, security, or compatibility issues, that can affect the performance and reliability of the devices.
✑ Moving the devices closer to the modem. Moving the devices closer to the modem
may not solve the issue, as the problem is not related to the distance between the devices and the modem, but to the signal power and quality of the cable. Moreover, moving the devices closer to the modem may not be feasible or convenient for the user, depending on the layout and setup of the location.
✑ Lowering the network speed. Lowering the network speed may not solve the issue,
as the problem is not related to the bandwidth or capacity of the network, but to the signal power and quality of the cable. Moreover, lowering the network speed may degrade the user experience and satisfaction, as the user may not be able to access or use the network services or applications as expected.
