Question #97
A product advertising kiosk at a mall is set up using a thin client without a hard drive and is running a web application managed and updated through an internet connection.
Which of the following application delivery methods is most likely being used for the kiosk?
- A . Local network-hosted
- B . Cloud-hosted
- C . Hybrid-installed
- D . Locally installed
Correct Answer: B
B
Explanation:
The application delivery method that is most likely being used for the kiosk is cloud-hosted. Cloud-hosted is a type of application delivery method that involves running and accessing an application from a remote server or service over the internet. Cloud-hosted applications do not require installation or storage on the local device, but only a web browser or a client software to connect to the application. Cloud-hosted applications can provide benefits such as scalability, availability, security, and automatic updates. A product advertising kiosk at a mall that is set up using a thin client without a hard drive and is running a web application managed and updated through an internet connection is most likely using a cloud-hosted application delivery method, as it does not need any local resources or maintenance for the application. Local network-hosted is not the application delivery method that is most likely being used for the kiosk, but rather a type of application delivery method that involves running and accessing an application from a server or a device within the same local area network (LAN) as the client device. Local network-hosted applications require installation or storage on the server or device that hosts the application, but not on the client device. Local network-hosted applications can provide benefits such as speed, reliability, and control. A product advertising kiosk at a mall that is set up using a thin client without a hard drive and is running a web application managed and updated through an internet connection is not likely using a local network-hosted application delivery method, as it would need to be connected to a server or device within the same LAN as the kiosk. Hybrid-installed is not the application delivery method that is most likely being used for the kiosk, but rather a type of application delivery method that involves running and accessing an application from both a local device and a remote server or service over the internet. Hybrid-installed applications require partial installation or storage on the local device, as well as a web browser or a client software to connect to the remote part of the application. Hybrid-installed applications can provide benefits such as flexibility, functionality, and performance. A product advertising kiosk at a mall that is set up using a thin client without a hard drive and is running a web application managed and updated through an internet connection is not likely using a hybrid-installed application delivery method, as it would need some local resources for the application. Locally installed is not the application delivery method that is most likely being used for the kiosk, but rather a type of application delivery method that involves running and accessing an application from the local device only. Locally installed applications require full installation or storage on the local device, but do not need any web browser or client software to connect to the internet. Locally installed applications can provide benefits such as offline access, customization, and compatibility. A product advertising kiosk at a mall that is set up using a thin client without a hard drive and is running a web application managed and updated through an internet connection is not likely using a locally installed application delivery method, as it would need a hard drive or other storage device for the application.

Question #98
Which of the following is the largest storage capacity?
- A . 1PB
- B . 100TB
- C . 9,000GB
- D . 9,900MB
Correct Answer: A
A
Explanation:
Comparing storage capacities requires understanding the magnitude of each unit. The hierarchy from smallest to largest is megabytes (MB), gigabytes (GB), terabytes (TB), and then petabytes (PB).
1 PB (petabyte) = 1,000 TB (terabytes)
100 TB = 100 terabytes
9,000 GB = 9 terabytes
9,900 MB = 0.0099 terabytes
Therefore, 1 petabyte (PB) is significantly larger than the other options listed.
Reference: Storage capacity units and conversions are covered in IT fundamental courses and materials, including those by CompTIA.

Question #99
A small company has authorized an allowance for employees to purchase their own work computers. The administrator has noticed a sizable increase in network traffic following the arrival of the new computers.
Which of the following is the most likely reason?
- A . Unnecessary OEM software
- B . Lack of antivirus present
- C . Online gaming activity
- D . Firewalls are not configured
Correct Answer: C
C
Explanation:
Online gaming activity is the most likely reason for the increase in network traffic because it consumes a lot of bandwidth and data. Online games often require constant communication with servers and other players, which can generate a lot of network traffic. Unnecessary OEM software, lack of antivirus, and firewalls are not configured are less likely to cause such a significant increase in network traffic, as they are either one-time or periodic processes that do not require as much data transfer as online gaming.
