1. 1What physical phenomenon carries an RF signal through space?

   1. A. A mechanical pressure wave
   2. B. An electromagnetic wave
   3. C. A stream of electrons crossing between antennas
   4. D. A vibration transmitted through a solid material

   Answer: B

   Explanation: NASA describes radio frequency as one of the "different frequencies of the same phenomenon: electromagnetic radiation." RF propagates as electromagnetic fields. Pressure waves and solid vibrations are mechanical disturbances; radio propagation does not require electrons to travel from one antenna to the other.

2. 2Which IEEE 802.11 amendment introduced WLAN operation in sub-1 GHz frequencies?

   1. A. 802.11ah
   2. B. 802.11ac
   3. C. 802.11ad
   4. D. 802.11ax

   Answer: A

   Explanation: IEEE describes Task Group ah as defining "operation in Sub 1 GHz frequencies." The 802.11ah amendment introduced that operation. The other listed amendments specify different WLAN developments rather than this sub-1 GHz extension.

   Reference: Overview of the IEEE 802.11 Working Group — Task Group ah (TGah)

3. 3When a Meraki MR AP uses NAT mode with Meraki DHCP, how do clients' outbound connections appear on the wired LAN?

   1. A. With every client's original private address unchanged
   2. B. With a new public address assigned by each client
   3. C. With the cloud dashboard's management address
   4. D. With the AP's LAN IP address as the translated source

   Answer: D

   Explanation: Meraki states, "Outbound connections will be initiated with the LAN IP address of the AP using Network Address Translation." This is AP-based NAT, rather than transparent bridging, client-selected addressing, or forwarding through the cloud dashboard.

4. 4A hospital requires clinical wireless services to remain available if an AP or controller fails. Which proposal addresses that requirement?

   1. A. A single controller with more capacity but no controller failover
   2. B. Alternate AP coverage and controller redundancy with tested failover
   3. C. Redundant controllers with no alternative coverage after an AP failure
   4. D. Overlapping AP coverage with a single unprotected controller

   Answer: B

   Explanation: The healthcare profile states, "The network should be able to sustain catastrophic events such as AP or Controller outage." The stated goal covers both failure types, so the proposal must validate alternate AP coverage and controller recovery. Controller capacity alone or redundancy for only one of the two failure domains leaves the other unaddressed.

5. 5Which RF characteristic specifies how many wave cycles occur each second?

   1. A. Amplitude
   2. B. Wavelength
   3. C. Frequency
   4. D. Polarization

   Answer: C

   Explanation: NASA states, "The number of cycles, or times that a wave repeats in a second, is called frequency." Amplitude concerns strength, wavelength concerns spatial length, and polarization concerns field orientation.

6. 6Which radio-frequency band is used for Bluetooth wireless communications?

   1. A. 900 MHz
   2. B. 2.4 GHz
   3. C. 5 GHz
   4. D. 6 GHz

   Answer: B

   Explanation: The Bluetooth SIG states, "Bluetooth® technology uses the 2.4 GHz ISM spectrum band (2400 to 2483.5 MHz)". The other bands do not describe the operating band of Bluetooth.

7. 7How can CW9166 integration with Meraki Systems Manager support a policy that depends on managed-device posture?

   1. A. Use endpoint management context to apply firewall and traffic policies
   2. B. Assign every endpoint the same posture because it uses the same SSID
   3. C. Treat successful WLAN association alone as proof of device compliance
   4. D. Substitute the AP hardware inventory for each endpoint's posture

   Answer: A

   Explanation: The datasheet says Systems Manager can "dynamically tie firewall and traffic shaping policies to client posture." The integration supplies endpoint context for policy. A common SSID, successful association, or AP inventory alone does not establish each endpoint's managed compliance state.

8. 8In the Meraki hospitality design model, which group of services belongs to House Access rather than Guest Access?

   1. A. Complimentary guest web browsing and social media
   2. B. Paid convention-attendee Internet service
   3. C. Guest-room access to personal streaming accounts
   4. D. Point of sale, room automation, and property management

   Answer: D

   Explanation: The guide describes "House Access which hosts Point of Sale, room automation, and property management system (PMS) solutions". Guest Access serves complimentary or paid Internet access; the hotel's operational systems belong to the house-service use case.

9. 9Which characteristic describes the strength of an RF wave?

   1. A. Amplitude
   2. B. Frequency
   3. C. Wavelength
   4. D. Phase

   Answer: A

   Explanation: NASA explains, "The strength, or intensity of the wave (analogous to a sound wave's loudness) is known as its amplitude." Frequency measures repetition and wavelength measures spatial length. Phase describes relative position within a cycle rather than wave strength.

   Reference: Basics of Space Flight — Chapter 6: Electromagnetics — Electromagnetic Spectrum

10. 10Which frequency band is used by IEEE 802.11a WLANs?

    1. A. 60 GHz
    2. B. 2.4 GHz
    3. C. 5 GHz
    4. D. 6 GHz

    Answer: C

    Explanation: In its 802.11a entry, IEEE states, "It supported 5 GHz operation and its 20 MHz bandwidth supported multiple data rates." Confusing 802.11a with 802.11b/g or newer 6 GHz operation leads to the other answers.
