Practice test questions 4 Flashcards
A user submits a trouble ticket for their laptop. The user states that every time they move the laptop from one place to another, the system loses power and shutdowns. You have examined the laptop fully and then removed and reinstalled the hard drive, RAM, ribbon cable to the LCD, and the battery, but the laptop is still shutting down whenever it is moved. What is MOST likely causing the issue with this laptop shutting down?
Battery connection is loose. Based on the symptoms provided (laptop shutting down whenever it is moved), it is most likely a loose battery connection causing the issue. If the battery connection wasn’t loose and the laptop was unplugged, the laptop would continue to run on battery power. Overheating can cause a laptop to shut down, but it wouldn’t necessarily happen each time the laptop is moved. If the CMOS battery fails, it will not cause the laptop to shut down, but instead will cause the laptop to lose the correct date/time.
What types of hard drives would be used in a gaming laptop to increase the system’s boot-up performance while providing a large amount of storage at a lower overall cost?
Hybrid Drive. A hybrid hard drive (SSHD) is a storage drive that combines the large storage capacity of an HDD with the faster read/write speed of an SSD. The majority of the drive uses a spinning disk and actuator arm, like a traditional magnetic drive, but it also contains a small SSD (solid-state drive) as part of the combined hybrid drive unit. This allows data to be written to either the SSD portion (for data accessed more frequently like the OS and programs) while using the HDD portion to store larger amounts of rarely accessed files (such as photos and video files). Hybrid hard drives constantly monitor the data retrieved from storage, and it automatically determines which data you open the most. It places the files that you use most often on the SSD to read/write that data faster.
You have been asked to fix an old computer whose CD-ROM has stopped working. The CD-ROM drive is using a 40-pin ribbon cable, and you suspect the cable is defective. What cable should you buy to replace the cable?
IDE. An IDE (Integrated Drive Electronics) cable is an older cable interface that used to be used for the transmission of data between the motherboard and various internal devices like hard drives and CD-ROM drives. An IDE cable is a 40-pin ribbon cable that operated at relatively slow speeds (less than 50 Mbps). IDE cables were also known as PATA (Parallel ATA) cables, as opposed to SATA (Serial ATA) cables. You will rarely come across an IDE cable in use today, but if you are working on a very old computer in an office (legacy machine) then you may find one in use.
Your office has a legacy wide-format printer that must be connected to your network. The connection on the printer is an older DB-9 serial connection. What is the BEST option for connecting this legacy device to your corporate network?
Purchase an RS-232 to RJ-45 adapter so that you can connect it to the network. The most convenient and least expensive way to connect the printer would be to buy an RS-232 to RJ-45 adapter, which will allow you to connect the legacy printer to the network directly. Then, the printer will be accessed by all users directly from their computers while printing to it using the appropriate print drivers. Networks do not have USB connections, so you need to select a network connection type like RJ-45 to use instead.
You are configuring a print server on the network. What type of IP address should you configure it with?
Static. A static IP address should be used for servers to ensure they are easy to find, access, and manage on the network. When configuring a static IP address, you need to include the IP address, subnet mask, gateway, and DNS server’s IP address. A static IP address is used when the DHCP server is disabled and clients are configured manually to join the network properly. A dynamic IP address is configured automatically by a DHCP server when a new host joins the network.
What cloud computing concept is BEST described as focusing on the replacement of applications and programs on a customer’s workstation with cloud-based resources?
SaaS. Software as a Service (SaaS) is ca loud computing service that enables a service provider to make applications available over the Internet to end-users. This can be a calendar, scheduling, invoicing, word processor, database, or other programs. For example, Google Docs and Office 365 are both word processing SaaS solutions. Infrastructure as a Service (IaaS) is a cloud computing service that enables a consumer to outsource computing equipment purchases and running their own data center.
What motherboard form factor measures 6.7” x 6.7” (17 cm x 17cm) in size?
mITX. The mITX (Mini-ITX) form factor is 6.7” x 6.7” in size (17 cm x 17cm). The mITX is commonly used in smaller computer systems with a small form factor (SFF) case. These motherboards are usually used in computers designed for passive cooling and a low power consumption architecture, such as a home theater PC system. The mATX (microATX) motherboard’s form factor is 9.6” x 9.6” in size (24 cm x 24 cm). The mATX form factor is commonly used in smaller computer systems with a small form factor (SFF) case. An mATX motherboard is backward-compatible with the larger ATX motherboard since it contains the same mounting point locations as the full-size board. An ATX motherboard’s form factor is 12” x 9.6” in size (305mm x 244mm). ITX is a series of form factors that began with the mini-ITX, but there is no specific size called ITX.
As a PC Technician, you are on the road most of the day and use a laptop. When you get back to your office at the end of the day, you would like to be able to quickly connect a larger external monitor, keyboard, and mouse to your laptop through a single USB port to perform additional work on the larger screen. What type of device should you choose to provide all the functionality above?
Port Replicator. A port replicator is a simple device to extend the range of ports (for example, USB, DVI, HDMI, Thunderbolt, network, and so on) available for a laptop computer when it is used at a desk. A docking station is a sophisticated type of port replicator designed to provide additional ports (such as network or USB) and functionality (such as expansion slots and drives) to a portable computer when used at a desk. The difference between a docking station and a port replicator is that a docking station can add additional capabilities beyond what is already integrated into the laptop whereas a port replicator can only reproduce the same ports that already exist on the laptop. Thunderbolt is a connector type that can be used either as a display interface (like DisplayPort) or as a general peripheral interface (like USB 3). Thunderbolt 3 uses USB-C connectors. A USB hub is a device that connects to a USB port to allow additional USB devices to be connected to the PC, essentially increasing the number of USB ports available.
What devices would allow you to control and provide input commands to multiple servers within the same server rack using a single set of input devices?
KVM. A keyboard video mouse (KVM) switch is used to support a single set of input and output devices controlling several PCs. A KVM is typically used with servers but 2- port versions allow a single keyboard, mouse, and display to be used with two PCs. Generally, a single KVM installed in each server rack allows the administrator to quickly switch between physical servers within the rack using the same keyboard, mouse, and monitor. A touchpad is an input device used on most laptops to replace a mouse. The touchpad allows the user to control the cursor by moving a finger over the pad’s surface. A mouse is an input device that is used to control the movements of a cursor and to select objects on the screen. A keyboard is an input device that is used to enter data into a computer using different key layouts based on the geographical region in which it is used.
What type of cloud service provides users with an end-to-end application solution for a recurring monthly or yearly fee?
SaaS. Software as a service (or SaaS) is a way of delivering applications over the Internet as a service. Instead of installing and maintaining software, you access it via the Internet, freeing yourself from complex software and hardware management. It allows a company to pay a monthly or yearly fee to receive access to the software without managing the software locally within their own network. For example, many small businesses use Shopify to create an online e-commerce store that is classified as a SaaS product. Other examples include G Suite, Office 365, or Adobe Creative Cloud. Platform as a Service (PaaS) is a cloud computing service that enables consumers to rent fully configured systems that are set up for specific purposes.
What of the following ports is used by SNMP by default?
- The simple network management protocol (SNMP) is a protocol for monitoring and managing network devices over UDP ports 161 and 162. A management system collates data sent by agents running on each device. The agents maintain a Management Information Base of configuration and usage data. An agent can also generate a trap, alerting the management system of some notable event. The simple mail transfer protocol (SMTP) is the protocol used to send mail between hosts on the Internet using TCP port 25. The domain name system (DNS) protocol is the protocol used to provide names for an IP address based on their mappings in a database using TCP/UDP port 53.
Your firewall is blocking outbound email traffic that is attempting to be sent. What port should you verify is set to ALLOW in the firewall to ensure your emails are being sent?
- The simple mail transfer protocol (SMTP) is the protocol used to send mail between hosts on the Internet using TCP port 25. Port 25 must be set to OPEN or ALLOW in the firewall for SMTP (Sendmail transfer protocol) to function properly. Secure shell (SSH) is the protocol used for remote administration and file copying using TCP port 22. SSH is considered secure since it uses authenticated and encrypted sessions for communication. Secure shell (SSH) is the protocol used for remote administration and file copying using TCP port 22.
John is setting up 100 Windows 10 computers for a new corporate office. He wants to ensure that no one can change the boot order and boot from an unauthorized operating system. What feature should he ensure is enabled?
BIOS Password required. John should utilize the BIOS to set up a password to prevent unauthorized access to the Basic Input/Output System (BIOS) by other users. The BIOS is software that utilizes a small memory chip on the motherboard to hold the settings specialized for an organization to prevent access and tampering, thus reducing the workstations’ overall attack surface and the network. Full disk encryption is used to encrypt the user and system data stored in the device’s internal storage. RAM integrity checking is conducted by default on most systems during the initial boot process but it doesn’t prevent a user from booting the system or changing the boot order. The purpose of Secure Boot is to prevent malicious and unauthorized apps from loading into the operating system (OS) during the startup process. Secure Boot is enabled by default in Windows 10.
A computer technician is trying to set up a shared printer on the corporate network. The users must send print jobs directly to the printer, and the printer will be used by multiple operating systems, including Windows, macOS, and Linux. What of the following should the technician configure to meet these requirements best?
TCP/IP printer server. The technician should set up a TCP/IP print server since it will eliminate any compatibility issues associated with using different operating systems and allow the users to send jobs directly to the printer. TCP/IP printing is considered a high-speed and reliable method for sending a print job directly to a printer. AirPrint is a feature in the macOS and iOS operating systems, it does not support Windows or Linux. Bonjour is Apple’s implementation of zero-configuration networking and does not support Windows or Linux systems. Virtual printers can print a document to a PDF or XPS file, therefore this will not let user’s send documents to the printer for physical printing.
A salesman has been traveling to different businesses all day to give a sales presentation. Each time, he starts up his laptop and logs into Windows to show his PowerPoint presentation to the customer. During his second appointment, his laptop lost power and shut itself off abruptly. He arrives at his third appointment and plugs in his laptop to recharge it. When he powers on his laptop, he sees a very low-resolution version of his normal desktop. He attempts to change the resolution from 800 x 600 to 1920 x 1080 (his normal resolution) but cannot find it in the Display Settings options inside of Windows. What could be the cause of this error?
Corrupted or missing display driver. If your display is shown in low resolution (640 x 480 or 800 x 600), but the computer isn’t in Safe Mode, it is usually a driver issue. For some reason, the laptop’s display driver has become corrupted between the salesman’s last appointment and this appointment. Without a valid display driver, Windows will revert to the “Generic VGA” driver, limiting the system’s highest resolution to 1024 x 768. To solve this issue, you should reinstall a new display driver for the laptop’s appropriate graphics card.
