Supporting Wireless Solutions questions tend to give symptom sets and ask which diagnostics or remediation steps to take using KPIs such as latency, retries, and packet loss. Practice reading AP and controller logs, correlate client-side versus network-side metrics, and know simple escalation steps, which helped me pass the CWISA-103.

Planning Wireless Solutions questions are often scenario-based, asking you to produce heatmap-driven AP placement, estimate capacity for device density, or create a channel reuse plan for a building layout. Focus on translating device counts into throughput needs, interpreting site survey outputs, and regulatory channel constraints, I relied on those planning skills to clear the CWISA-103.

Free CWNP CWISA-103 Exam Actual Questions

Note: Premium Questions for CWISA-103 were last updated On Aug. 31, 2026 (see below)

Question #1

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

Reveal Solution Hide Solution
Correct Answer: C

Encryption vs. Other Options:

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.


Encryption standards and protocols:Resources on common wireless encryption types (WPA2, WPA3, TLS) and their implementation.

Question #2

What is the typical range of a wireless body area network (WBAN)?

Reveal Solution Hide Solution
Correct Answer: A

WBAN Range:Wireless Body Area Networks (WBANs) specialize in short-range communication around the human body. Typical ranges fall within 1-2 meters.

Purpose:This range is designed to:

Connect sensors monitoring health metrics.

Transmit data to a central coordinator device (e.g., smartphone).

Minimize interference potential with other wireless networks.

Question #3

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

Reveal Solution Hide Solution
Correct Answer: C

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).

Other Protocols Have Different Purposes:

IPSec: Secures IP traffic at a network level, can be used alongside TLS.

SNMPv3: Management protocol, offers security features, but not the primary mechanism in HTTPS.

SSH: Secure remote shell, unrelated to web data encryption.


TLS (and SSL):Explanations of their role in HTTPS and how they provide encryption for web communication.

HTTPS Overview:Materials showing how TLS fits into the overall HTTPS architecture.

Question #4

What is the primary difference between LoRa and LoRaWAN

Reveal Solution Hide Solution
Correct Answer: B

LoRa:This refers to the underlying radio modulation technique using Chirp Spread Spectrum (CSS). It defines how data is physically encoded onto the wireless signal.

LoRaWAN:This is the network protocol built on top of LoRa. It manages device communication, network topology, and aspects like security. It operates at the MAC sublayer of the Data Link layer (Layer 2) of the OSI model

LoRa vs. LoRaWAN:Key takeaway is that LoRa is the physical layer technology, while LoRaWAN adds the networking layer for management.


LoRa Modulation:Technical explanations of Chirp Spread Spectrum (CSS).

LoRaWAN Specification:Official documentation detailing the network architecture and MAC layer functions.

OSI Model:Descriptions of the Data Link layer and its role in networking.

Question #5

How does OFDMA differ from OFDM?

Reveal Solution Hide Solution
Correct Answer: C

OFDM vs. OFDMA:

OFDM (Orthogonal Frequency-Division Multiplexing):Divides a channel into multiple subcarriers for data transmission.

OFDMA (Orthogonal Frequency-Division Multiple Access):Extends OFDM by allowing multiple users to share subcarriers simultaneously, improving efficiency and spectral utilization.
