CWISA-103 Lernhilfe, CWISA-103 Exam

Im Informationszeitalter kümmern sich viele Leute um die IT-Branche. Aber es fehlen trozt den vielen Exzellenten doch IT-Fachleute. Viele Firmen stellen ihre Angestellte nach ihren Fragenkataloge Zertifikaten ein. Deshalb sind die Zertifikate bei den Firmen sehr beliebt. Aber es ist nicht so leicht, diese Zertifikate zu erhalten. Die CWNP CWISA-103 Zertifizierungsprüfung ist eine schwierige Zertifizierungsprüfung. Obwohl viele Menschen beteiligen sich an der CWNP CWISA-103 Zertifizierungsprüfung, ist jedoch die Pass-Quote eher niedrig.

CWNP Certified Wireless IoT Solutions Administrator(2025 Edition) CWISA-103 Prüfungsfragen mit Lösungen (Q77-Q82):

77. Frage
What process, used for security in wireless solutions, is defined as the encoding of information to prevent readability by unauthorized users?

A. Encryption
B. Access Control
C. Authorization
D. Authentication

Antwort: A

Begründung:
Access Control: Limits who can access data, but doesn't make it unreadable.
Authentication: Validates user/device identity, but not focused on data confidentiality.
Authorization: Determines the actions a user is allowed, separate from securing the data itself.
How encryption works: Encryption uses algorithms and keys to turn plaintext into unreadable ciphertext. Only those with the correct key can decrypt it.
Data in motion vs. data at rest: Encryption protects sensitive information both when transmitted over the wireless network and when stored on devices.

78. Frage
What provides the security (encryption) in an HTTPS connection?

A. SNMPv3
B. SSL/TLS
C. IPSec
D. SSH

Antwort: B

Begründung:
SSL/TLS Secures Web Traffic: HTTPS builds upon HTTP, adding the encryption provided by Secure Sockets Layer (SSL) or its successor, Transport Layer Security (TLS).

79. Frage
As an RF signal propagates it becomes weaker as it gets farther away from the transmitter. What concept is described?

A. Diffraction
B. Free Space Path Loss
C. Beamwidth
D. RF latency

Antwort: B

Begründung:
The concept described is Free Space Path Loss (FSPL). FSPL refers to the reduction in power density of an electromagnetic wave as it propagates through a clear, unobstructed path in free space. This weakening of the signal is due to the spreading of the wavefront as it travels, causing the power to be distributed over a larger area. The FSPL can be calculated using the Friis Transmission Equation, which shows that the received power decreases with the square of the distance from the transmitter. This concept is fundamental to understanding the behavior of RF signals in various communication systems, including wireless IoT, where the signal strength at the receiver is a critical factor for reliable data transmission.

80. Frage
Which one of the following location tracking technologies is most energy efficient in typical implementations?

A. Wi-Fi
B. Cellular
C. GPS
D. BLE Beacons

Antwort: D

Begründung:
* BLE Beacon Power Efficiency: Bluetooth Low Energy (BLE) beacons are designed for low power consumption. Their primary function is to periodically broadcast short data packets (advertising their presence).
* Other Technologies:
* Cellular: More power-hungry due to long-range communication and complex protocols.
* GPS: Power intensive, especially when actively tracking location.
* Wi-Fi:

81. Frage
What kind of PoE device can be used to power a non-PoE connected object assuming PoE power is provided on the Ethernet cable?

A. PoE endspan switch
B. PoE coupler
C. PoE splitter
D. PoE midspan injector

Antwort: C

Begründung:
* PoE Splitter: A PoE splitter separates power and data from a PoE-enabled Ethernet cable, allowing the powering of non-PoE devices.
* Other PoE Devices:
* PoE Injector: Adds power to non-PoE Ethernet cable.
* PoE Switch: Provides power directly through its ports.

82. Frage
......
