Question #61
Given the following pseudocode:
If the Breakfast program ran on Sunday, which of the following would be the output?
- A . Oatmeal
- B . Bacon and eggs
- C . Waffles
- D . Pancakes
Correct Answer: D
D
Explanation:
The output of the Breakfast program if it ran on Sunday would be pancakes. The program uses an if-else-if-else statement to choose among different breakfast options based on the day of the week input. The program first checks if the day input is equal to “Saturday”. If this condition is true, it prints “Waffles” and ends. If this condition is false, it checks if the day input is equal to “Sunday”. If this condition is true, it prints “Pancakes” and ends. If this condition is false, it prints “Oatmeal” and ends. Since the day input is “Sunday”, the second condition is true, and the program prints “Pancakes”.

Question #62
Which of the following is an example of an interpreted language?
- A . C++
- B . Java
- C . Python
- D . Go
Correct Answer: C
C
Explanation:
Python is an example of an interpreted language, which is a type of programming language that does not need to be compiled before execution. Instead, an interpreter program translates and executes the source code line by line at run time. Interpreted languages are usually easier to write and debug, but slower to execute than compiled languages. C++ and Java are examples of compiled languages, which are types of programming languages that need to be translated into executable machine code by a compiler program before execution. Compiled languages are usually faster to execute but harder to write and debug than interpreted languages. Go is an example of a hybrid language, which is a type of programming language that combines features of both compiled and interpreted languages. Hybrid languages use an intermediate code that can be executed by a virtual machine or an interpreter at run time.

Question #68
Which of the following connection types is typically used for a display monitor?
- A . USB
- B . DVI
- C . Bluetooth
- D . RJ45
Correct Answer: B
B
Explanation:
The connection type that is typically used for a display monitor is DVI. DVI stands for Digital Visual Interface, which is a standard that defines how digital video signals are transmitted from a source device, such as a computer or a DVD player, to a display device, such as a monitor or a projector. DVI can support various resolutions and refresh rates, depending on the type and length of the cable and the capabilities of the devices. DVI can also support analog video signals, using a DVI-A connector, or both digital and analog video signals, using a DVI-I connector. However, DVI does not support audio signals, so a separate audio cable is needed. USB is not the connection type that is typically used for a display monitor, but rather a connection type that is typically used for peripheral devices, such as keyboards, mice, printers, scanners, etc. USB stands for Universal Serial Bus, which is a standard that defines how data and power are transmitted between devices using a common interface. USB can support various types and speeds of devices, depending on the version and mode of the USB port and cable. USB can also support video and audio signals, using a USB-C connector, which can be converted to other standards, such as HDMI or DisplayPort. Bluetooth is not the connection type that is typically used for a display monitor, but rather a connection type that is typically used for wireless devices, such as headphones, speakers, keyboards, mice, etc. Bluetooth is a technology that defines how data and audio are transmitted between devices using short-range radio waves. Bluetooth can support various profiles and protocols that enable different types of communication and functionality between devices. Bluetooth can also support video signals, using a Bluetooth Low Energy Video Streaming (BLE-VS) protocol, but it is not widely adopted or supported by most devices. RJ45 is not the connection type that is typically used for a display monitor, but rather a connection type that is typically used for network devices, such as routers, switches, computers, etc. RJ45 stands for Registered Jack 45, which is a connector that defines how data are transmitted between devices using twisted pair cables. RJ45 can support various standards and speeds of network communication, depending on the category and length of the cable and the capabilities of the devices. RJ45 can also support video signals, using an Ethernet AVB (Audio Video Bridging) protocol, but it is not widely adopted or supported by most devices.

Which of the following descriptions is correct?
- A . LAN access Is required.
- B . The application exists locally.
- C . Files are saved in the cloud.
- D . Internet access Is required.
Correct Answer: A
A
Explanation:
LAN access is required for an application that is hosted on a local network. A local network, also known as a local area network (LAN), is a group of devices that are connected within a limited geographic area, such as a home, an office, or a school. A LAN allows the devices to communicate and share resources, such as files, printers, or applications. An application that is hosted on a local network means that the application is installed and running on one or more devices within the LAN, and can be accessed by other devices within the same LAN. However, to access the application, the device must be connected to the LAN, either by a wired or wireless connection. The application does not exist locally on the device that accesses it, unless it is also installed on that device. The application does not save files in the cloud, unless it has a feature that allows it to sync with a cloud service. The application does not require internet access, unless it needs to communicate with external servers or services outside the LAN.
