NEW QUESTION # 13
You are defining capacity for a wireless solution. What is the most important factor related to each use case defined in relation to capacity?
- A. Number of devices
- B. Protocols used on each device
- C. Total airtime utilization
- D. Support for mobility
Answer: A
Explanation:
Capacity Planning: The number of devices a wireless network can support is the primary determinant of its required capacity. This is because:
Traffic Load: Each device generates network traffic that contributes to the overall load.
Resource Sharing: Devices compete for airtime and bandwidth resources.
Device Type: Requirements vary; a simple sensor has different needs than a video camera.
NEW QUESTION # 14
What is an advantage of an overlay monitoring system for wireless networks as opposed to an Integrated monitoring system?
- A. An overlay solution functions without disrupting services provided by the wireless network
- B. An overlay solution collects less data so that reporting is more efficient
- C. An overlay solution is less expensive than an integrated solution
- D. An overlay solution does not require power provisioning
Answer: A
Explanation:
Overlay vs. Integrated Monitoring:
Overlay: A separate monitoring system independent of the primary wireless infrastructure.
Integrated: Monitoring functions built into wireless access points or controllers.
Overlay Advantage: Since the overlay system is separate, it doesn't add overhead or complexity to the core network, avoiding potential disruption of wireless services.
NEW QUESTION # 15

NEW QUESTION # 16
In a wireless link, as the signal strength decreases, what else may decrease?
- A. Interference
- B. Latency
- C. Transmission speeds
- D. Noise
Answer: C
Explanation:
Signal Strength and Data Rate: In wireless links, weaker signal strength often directly correlates to reduced transmission speeds. Modern wireless technologies use adaptive modulation and coding, sacrificing speed for reliability when signals become weaker.
Noise and Interference: While these can impact performance, they don't inherently decrease simply because signal strength drops.
Latency: Latency can be affected by poor signal, but its primary drivers are distance and network congestion.
References:
Wireless Signal Strength vs. Speed: Articles explaining the relationship and how adaptive modulation works.
Modulation and Coding Schemes (MCS): Technical descriptions of how Wi-Fi and other wireless technologies adjust speeds based on signal quality.

NEW QUESTION # 19
What statement best describes the difference between authentication and authorization?
- A. Authentication is used in wireless solutions and authorization is not
- B. Authentication ensures privacy and authorization ensures availability
- C. Authentication is not used in wireless solutions and authorization is used in wireless solutions
- D. Authentication proves identity and authorization determines access to specific resources
Answer: D
Explanation:
Authentication: Verifying "who" the user or device is (e.g., via passwords, certificates).
Authorization: Controlling "what" a user or device can do once authenticated (e.g., read-only vs. read/write permissions).
Combined for Security: Both are essential. Authentication alone doesn't control access levels, and authorization without verification is meaningless.
References:
Identity and Access Management (IAM): Articles and resources outlining the core principles of authentication and authorization.
Cybersecurity Best Practices: Guides on securing systems will often emphasize the need for both authentication and authorization controls.
NEW QUESTION # 20

NEW QUESTION # 21
What consideration is found in PtMP systems that is not found in PtP systems?
- A. Interference avoidance
- B. Airtime management
- C. SINR optimization
- D. Frequency selection
Answer: B
Explanation:
PtMP (Point-to-Multipoint): A single access point (AP) communicates with multiple client devices. This means the AP needs to manage how the available airtime is shared among those clients.
Airtime Fairness: Mechanisms are needed to ensure that:
Each client gets a fair chance to communicate
High-priority traffic isn't starved by low-priority traffic
PtP (Point-to-Point): A dedicated link only has two devices, eliminating the need for complex airtime management.
Considerations in Both: While interference, SINR, and frequency selection are important in both PtMP and PtP systems, the need for airtime management is unique to the multipoint scenario.
References:
Wireless Network Topologies (PtP vs. PtMP): References of the differences in how communication is managed in each scenario.
TDMA (Time Division Multiple Access): A common airtime sharing method used in PtMP systems.
NEW QUESTION # 22
What user authentication method is commonly used in guest Wi-Fi networks in the hospitality industry?
- A. SIM cards
- B. Kerberos
- C. NTLM
- D. Captive portal
Answer: D
Explanation:
Captive Portals for Guest Access: These are web pages that intercept users' requests before granting full internet access. They often require agreeing to terms, entering basic information, or viewing ads.
Hospitality Fit: Captive portals are simple to deploy, require minimal user setup, and provide control for the hospitality provider (e.g., usage limits).
Why Other Options Are Less Common:
NTLM: Microsoft authentication, mainly for corporate networks, too complex for casual guest use.
Kerberos: Complex authentication for enterprise, overkill for guest Wi-Fi SIM Cards: Used in cellular devices, not for general Wi-Fi access.
References:
Captive Portals: References of how they work and their use cases.
Guest Wi-Fi in Hospitality: Best practices highlight the prevalence of captive portals in this industry.

NEW QUESTION # 26
What process, used for security in wireless solutions, is defined as the encoding of information to prevent readability by unauthorized users?
- A. Access Control
- B. Authorization
- C. Authentication
- D. Encryption
Answer: D
Explanation:
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.

NEW QUESTION # 29
What is the primary difference between LoRa and LoRaWAN
- A. LoRa uses RF and LoRaWAN uses light-based communications
- B. LoRa is used for communicating across the Internet and LoRaWAN is used only on the local link
- C. LoRa is the modulation method (using CSS modulation at the Physical Layer) and LoRaWAN is the MAC sub-layer of the Data Link layer
- D. LoRa is the Physical Layer and LoRaWAN is the Transport Layer
Answer: C
Explanation:
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.
