質問 # 282
Which of the following has the best penetration through physical objects, such as walls?
正解：D
解説：
2.4GHz Wi-Fi signals have better penetration through walls and other obstacles compared to 5GHz and
6GHz. Lower frequency waves (like 2.4GHz) travel farther and are less absorbed by physical barriers.
From the CompTIA A+ 220-1101 Official Study Guide, Objective 2.5 - Compare and contrast wireless networking protocols:
"The 2.4GHz frequency band offers greater range and better penetration through walls and obstacles than higher frequencies like 5GHz and 6GHz. Higher frequencies provide faster speeds but are more easily absorbed by walls." NFC (Near Field Communication) is not a Wi-Fi technology and works only over very short distances (a few centimeters).

A marketing developer creates a new DNS record called promotions.comptia.org so it references the same IP address as
正解：C
解説：
A CNAME record creates an alias that points one domain name to another domain name, allowing promotions.comptia.org to resolve to the same IP address as www.comptia.org indirectly.
質問 # 284
A company deploys server machines in a public cloud. Which of the following cloud service models is this an example of?
正解：C
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. This includes virtual servers, storage, and networking. Deploying server machines falls under IaaS since the organization is responsible for managing the OS and applications on top of the infrastructure.

質問 # 285
Which of the following technologies can cause an application to open even though no device has been paired with the phone?
正解：D
解説：
Near-field communication can trigger a compatible application without requiring the phone to be paired with another device. NFC operates across a very short distance, normally only a few centimetres. When a phone is brought close to an NFC tag, payment terminal, access reader, or other NFC-enabled object, the tag can provide information that causes the operating system to open a browser, payment application, configuration screen, or another registered application.
Unlike Bluetooth, NFC does not require a conventional discovery and pairing process before exchanging the small amount of information needed to initiate the action. Wi-Fi connects the phone to a wireless local area network but does not inherently trigger an application through proximity. A hotspot allows the phone to share its cellular connection with other devices.
Bluetooth generally requires pairing or an established device relationship for persistent peripheral communication.
