Cisco Certified Support Technician (CCST) IT Support Sample Questions (Q126-Q131):
NEW QUESTION # 126
When attempting to charge their phone, a user notices that the charging symbol appears briefly but then disappears, and the phone does not charge.
What is a likely cause of this issue?
Answer: A
Explanation:
Correct Answer. A. The phone's charging port is dirty or obstructed Debris or dirt in the charging port can intermittently disrupt the connection between the charger and the phone, causing the charging symbol to appear briefly before disappearing.
Option B is incorrect because syncing with a computer is unrelated to the charging capability of the phone Option C is incorrect as background apps do not affect the physical ability of the phone to charge Option D is incorrect because airplane mode disables wireless transmissions but does not affect charging
NEW QUESTION # 127
A network administrator is troubleshooting connectivity issues on a small office network and finds that some devices have IP addresses assigned that are outside the subnet range specified by the DHCP server.
What should the administrator do first?
Answer: A
Explanation:
Correct Answer. C. Reconfigure the affected devices to receive IP addresses automatically from the DHCP server Ensuring that all devices are configured to automatically receive IP addresses from the DHCP server can eliminate issues with manual misconfigurations or static IP conflicts.
Option A is incorrect. Rebooting the DHCP server might temporarily disrupt the network and is not guaranteed to resolve configuration errors on client devices.
Option B is incorrect. While scanning the network can identify devices, it does not resolve the issue of devices being on the wrong subnet.
Option D is incorrect. Expanding the DHCP range does not address why some devices are set with incorrect static IPs.
NEW QUESTION # 128
During an office expansion, a technician sets up additional wireless access points. However, employees in the new area report intermittent WLAN connectivity despite the SSID being visible.
What is the most likely cause of this issue?
Answer: A
Explanation:
Correct Answer. B. The new access points have overlapping channels with existing ones Overlapping channels can cause interference and connectivity issues in environments with multiple access points.
Option A is incorrect. A lack of IP addresses would prevent connections but would not typically cause intermittent connectivity.
Option C is incorrect. While important, firmware updates are less likely to cause intermittent issues specifically related to new expansion areas.
Option D is incorrect. Cable quality affects wired connections, not the wireless signal quality or connectivity.
NEW QUESTION # 129
A user needs to connect a portable hard drive to their laptop using a Micro USB cable but is concerned about the security of their data during transfer. What is a critical aspect the IT support technician should inform the user about regarding the use of Micro USB for data transfer?
Answer: D
Explanation:
Correct Answer. C. Physical security of the connection is important as Micro USB does not provide data encryption When transferring data via Micro USB, it's important to ensure physical security of the connection, as the cable and port do not offer built-in encryption for data. Users should ensure secure handling and avoid public or untrusted charging points when transferring sensitive data.
Option A is incorrect because Micro USB cables do not inherently provide encryption for data transfers; this is managed by the devices and software involved.
Option B is incorrect because while USB 3.0 can offer faster data transfers, speed does not equate to increased security.
Option D is incorrect because Micro USB connections do not have the capability to automatically detect and disable transfers under security threats.
NEW QUESTION # 130
During a support call, a macOS user needs to verify their operating system version to troubleshoot compatibility issues with an application.
Which step should the technician recommend to accurately determine the macOS version?
Answer: C
Explanation:
Correct Answer. B. Click on the Apple menu and select "About This Mac" "About This Mac" from the Apple menu provides immediate, detailed information about the macOS version. This is the simplest and most direct method for users to find their OS version.
Option A is incorrect because "System Preferences" allows users to adjust settings but does not directly display the macOS version.
Option C is incorrect because while system_profiler in Terminal does provide extensive system details, it is more complex and may provide more information than necessary for just checking the OS version.
Option D is incorrect because navigating to System Preferences > Software Update primarily focuses on updating the software and might only incidentally display the current OS version.
