A user is expecting a visit from a new customer, and the company's ADSL link has suddenly gone down. Which of the following should the user do to access a smartphone's 4G internet connection from the laptop?
Answer: B
A hotspot would be the best option because it provides internet access to the PC or laptop using a cellular network ( 4G = LTE) from a mobile phone ( smartphone in our case ).

A user's laptop is running out of disk space and requires a new hard drive. The user wants to replace the existing hard drive with the fastest possible 1TB HDD. A technician assesses the user's hardware and determines the connections that are available. Which of the following drive types should the technician recommend as the BEST choice?
Answer: D
When CompTIA says HDD, they literally mean hard disk drive not SSD. I think you have to pick the only HDD option. The question says that the person wants the "fastest possible HDD", so that is what you pick, not what would actually make sense in real life so don't worry about SAS being for workstations etc.

Every time a user sends a print job, the user must walk over to the printer and press OK before the job will print. The same issue is occurring for multiple users. Which of the following is the MOST likely cause of the issue?
Answer: C
It can't be A is the job is already being queued to the printer. It is not B is there will probably be no communication to the printer at all if it is on another VLAN. D does not seem to apply in this scenario. Thus, it should be C. Typically means that the paper type and size configuration defaults on the printer have changed.

Which of the following concepts would be used by an online retailer to quickly add more web servers during peak sales times?
Answer: B
I agree with answer B. Rapid elasticity is the ability of the system to handle changes to demand in real-time and keep good performance; in this case, quick addition of the servers during peak sales time, so answer B is right. Community Cloud is for shared use by a few organizations ( corporate tenants) this is NOT the scenario. Metered service means tracking and paying for storage, precise computing, network service, etc - it is NOT the case here. High availability refers to when services experience very little downtime - it is NOT our case.

A network technician has been tasked with creating a patch cable. The RJ45 connectors will not stay attached to the cable. Which of the following tools is needed to fix this issue?
Answer: B
A and D are usually for testing or verifying cable connectivity. C does not really apply in this scenario. Since the RJ-45 connectors are not staying on the cable, the crimper would be used. Thus, the answer should be B.

To control costs, a company provides a limited number of users with company phones. One of these users opens a support ticket because the phone no longer allows Internet browsing over a cellular connection. The user acknowledges that the phone worked before the user’s child streamed several movies using the device. Which of the following describes why the phone cannot browse the internet?
Answer: C
I don't think so. I think they are trying to get us to confuse group policy with acceptable use policy. First since the company issued the phone, the company should have an MDM solution, so it should have blocked the user's child from streaming movies in the first place, much less several different movies at different times. But let's say they were not blocked and the company saw that the user violated the AUP so the phone's internet access is going to be disabled, then why would they only disable internet browsing over a cellular connection and not internet browsing over a WiFi connection as well? So as long as the user is on WiFi she can still do non-work-related stuff. I think the data cap limit is the correct answer.

A user’s desktop computer slows down after a few minutes of use, and the fans alternate between silent and very loud. Which of the following is MOST likely failing, therefore causing these symptoms?
Answer: A
Based on the given symptoms, the most likely failing component is the CPU fan. The alternating fan noise suggests that the fan is not functioning properly, which can cause the CPU to overheat and slow down the computer's performance. If the CPU overheats, it may cause the computer to shut down or cause permanent damage to the hardware. It is important to address this issue as soon as possible to avoid further damage to the computer.

A customer brings a phone to a repair shop because it is experiencing extreme slowness and applications are crashing. A technician attempts to install a diagnostic application, but the installation fails. Which of the following should the technician do FIRST to troubleshoot the issue?
Answer: A
A. Check the storage space. Options B, C, and D are unlikely to address the issue of extreme slowness and app crashes. Inspecting the screen for damage would not provide any insight into the performance of the device. Installing the latest updates or recalibrating the digitizer may help improve performance in some cases, but they are unlikely to address the specific issue of extreme slowness and app crashes.

Which of the following components enables the input on a mobile device's touch screen?
Answer: B
A. Incorrect - OLED is a new screen technology B. Correct - A digitizer is a device that converts analog signals to digital form. A device that converts human touch to a digital cue is a variant of this C. Incorrect - An inverter converts DC voltage to AC voltage D. Incorrect - A CMOS sensor is a chip that converts light to digital cues. This is different from a CMOS battery, which is a battery found on the motherboard to save BIOS settings.

A user is unable to connect a mobile phone while in a car. However, a second mobile device is able to connect in the same car. Which of the following settings should the user check on the first phone?
Answer: C
Bluetooth is commonly used to pair devices with the car so it is a correct answer. Wi-Fi means Wireless Network that required a wireless router, switch, or WAP to connect devices with each other and broadcast transmission to the Wide Area Network. Hotspot gives SSID from the cellular connection of the mobile phone to other devices ( laptops, tablets, other mobile phones, desktop computers, etc. ); it becomes like a kind of switch or router. Location does it matter here.
