Which of the following connectors supports High-bandwidth Digital Content Protection (HDCP)?
A. DVI-A
B. F-type
C. VGA
D. DisplayPort
Show Answer
Correct Answer: D
Explanation: HDCP is a digital content protection standard supported by digital video interfaces such as DisplayPort, HDMI, and certain forms of DVI. Among the options given, DisplayPort explicitly supports HDCP. DVI-A and VGA are analog-only, and F-type coaxial connectors are not used for HDCP-protected digital links.
Question 6
An IT specialist is setting up a new shared network printer. The printer will receive a pre-allocated IP address via DHCP. Attempting to connect to the printer's web interface produces a Page not found message. The specialist runs diagnostics and finds that the IP is different than expected. Which of the following should the specialist check next?
A. The MAC address used in the reservation
B. The printer driver on the print server
C. The subnet mask that the printer is using
D. The default gateway in the address pool
Show Answer
Correct Answer: A
Explanation: If the printer is supposed to receive a specific pre-allocated IP via DHCP but is instead getting a different address, the most likely issue is that the DHCP reservation is not matching the printer. DHCP reservations are tied to a device’s MAC address; if the wrong MAC address was entered or the printer is using a different interface/MAC than expected, the reservation will not apply. The other options would not cause the printer to receive a completely different IP from the DHCP server.
Question 7
An office is experiencing frequent wireless outages and slow network speeds. A technician confirms that all wireless devices are experiencing the same symptoms. Which of the following should the technician do to determine whether the issue is external or internal?
A. Restart all devices and ensure they join the workgroup.
B. Check the DNS configuration to make sure it is correct.
C. Connect a machine using Ethernet and test connectivity.
D. Perform a policy update on Active Directory and reset network settings.
Show Answer
Correct Answer: C
Explanation: Connecting a machine via Ethernet isolates the wireless network from the rest of the infrastructure. If the wired connection is stable and fast, the problem is internal to the wireless network (APs, interference, configuration). If issues persist on wired, the problem is likely external or upstream. This is the fastest way to distinguish internal vs. external causes.
Question 7
An administrator selects a new platform that provides the following benefits:
• Shares a host OS
• Shares kernel resources
• Rapid start and deployment
• Limited isolation
Which of the following virtualization options did the administrator select?
A. Type 1 hypervisor
B. Containers
C. Virtual desktop
D. Virtual machine
Show Answer
Correct Answer: B
Explanation: The described platform shares the host operating system and kernel, starts rapidly, and provides limited isolation—characteristics of container-based virtualization. Type 1 hypervisors and virtual machines have stronger isolation with separate kernels, and virtual desktops do not fit these traits.
Question 8
Which of the following DNS records should a technician configure to allow domains that are not owned by the company to send messages on the company's behalf?
A. SPF
B. MX
C. CNAME
D. DMARC
E. DKIM
Show Answer
Correct Answer: A
Explanation: SPF (Sender Policy Framework) records specify which mail servers or domains are authorized to send email on behalf of a domain, including third-party or external domains. This allows domains not owned by the company to legitimately send messages for the company. MX routes mail, CNAME aliases names, DMARC enforces policy, and DKIM signs messages but does not authorize senders.
Question 8
Users in a 200-person call center report that phone calls experience severe performance degradation on busy days. The technician confirms:
• Upload and download speeds are 50Mbps during a speed test.
• VoIP call prioritization settings are properly configured for the VLAN that the call center uses.
Which of the following is most likely the cause of this issue?
A. The QoS is not configured correctly on the router.
B. The switchports dedicated to the call center are flapping.
C. The call center’s VLAN is not configured to allow voice traffic.
D. The bandwidth dedicated to the call center is insufficient.
Show Answer
Correct Answer: D
Explanation: A 200-person call center generates significant simultaneous VoIP traffic, especially on busy days. Although QoS prioritization is correctly configured and speed tests show 50 Mbps, that bandwidth is likely shared with other traffic and insufficient to handle peak concurrent calls without degradation. Correct QoS cannot compensate for a lack of total available bandwidth, making insufficient bandwidth the most likely cause.
Question 9
A healthcare facility is printing government documents on preprinted forms. The output has shifted downward on the paper and the printed data is not aligned with the blank spaces on the forms. Which of the following should a technician do first?
A. Verify that the correct paper type is loaded into the tray.
B. Make sure that PostScript drivers are being used.
C. Check the orientation settings of the printer.
D. Ensure that the pickup rollers are firmly gripping the paper.
Show Answer
Correct Answer: A
Explanation: When printing on preprinted forms, vertical misalignment is most commonly caused by a mismatch between the form’s paper size/type and the printer’s tray or driver settings. Verifying that the correct paper type/size is loaded and selected ensures the printer uses the proper margins and feed offsets. Orientation settings would rotate content, pickup rollers affect feeding reliability, and PostScript drivers are not the first step for alignment issues.
Question 9
An organization upgrades all of its desktop machines to Windows 11. The organization must ensure that all machines are protected from malicious software on startup. Which of the following advanced options should the organization enable?
A. Trusted Platform Module
B. Hardware security module
C. Secure Boot
D. BIOS password
Show Answer
Correct Answer: C
Explanation: Secure Boot ensures that only trusted, digitally signed bootloaders and operating system components are allowed to run during system startup. This directly protects Windows 11 machines from malicious software that could load before the OS, making it the correct advanced startup protection option.
Question 10
A user's company-issued smartphone is swollen and will not fit in its protective enclosure. Which of the following would a technician most likely do?
A. Replace the battery.
B. Upgrade the RAM.
C. Change the case.
D. Restore to the factory settings.
Show Answer
Correct Answer: A
Explanation: A swollen smartphone is a classic sign of a failing or damaged lithium‑ion battery. Gas buildup inside the battery causes it to expand, pushing against the phone’s enclosure. The appropriate and safe technician response is to replace the battery, not change the case, upgrade RAM, or perform a factory reset.
Question 10
Which of the following is the best to use to stream real-time video from a network camera?
A. UDP
B. TCP
C. FTP
D. RDP
Show Answer
Correct Answer: A
Explanation: UDP is best for real-time video streaming because it has low latency and does not require retransmission of lost packets, which is preferable for live video where timely delivery is more important than perfect reliability. TCP adds latency due to acknowledgments and retransmissions, FTP is for file transfers, and RDP is for remote desktop sessions, not raw video streaming.
