ECMS MR Wireless Access Points and RF 1 — Questions and Answers
Question 1: What Meraki MR feature automatically adjusts transmit power and channel selection to optimize wireless coverage?
- Manual RF profiles
- Auto RF (Radio Resource Management) (Correct answer)
- Static channel planning
- Client-driven channel selection
Correct answer: Auto RF (Radio Resource Management)
Meraki Auto RF continuously analyzes the RF environment and automatically adjusts power levels and channels to minimize interference and optimize coverage.
Question 2: Which Meraki wireless security feature detects and alerts on unauthorized access points operating in the airspace?
- Auto VPN
- Air Marshal (Correct answer)
- SSID cloaking
- MAC address filtering
Correct answer: Air Marshal
Air Marshal is Meraki's built-in wireless intrusion detection system (WIDS) that identifies rogue APs, evil twin attacks, and other wireless threats.
Question 3: In Meraki dashboard, what is an 'RF Profile' used for?
- Defining SSID broadcast schedules
- Configuring channel, power, and band steering settings for a group of APs (Correct answer)
- Setting VLAN assignments per AP
- Managing AP firmware rollout groups
Correct answer: Configuring channel, power, and band steering settings for a group of APs
RF Profiles in Meraki allow administrators to define radio settings including channel width, minimum bitrate, and band steering behavior and apply them to APs by group.
Question 4: What is the purpose of Meraki's 'Band Steering' feature on MR access points?
- It physically steers the antenna beam toward clients
- It encourages dual-band clients to connect to the 5 GHz band instead of 2.4 GHz (Correct answer)
- It blocks single-band 2.4 GHz-only clients from connecting
- It combines 2.4 and 5 GHz into a single virtual band
Correct answer: It encourages dual-band clients to connect to the 5 GHz band instead of 2.4 GHz
Band steering uses 802.11k/v mechanisms to encourage capable clients to associate with the less congested 5 GHz radio instead of 2.4 GHz.
Question 5: Which authentication method on a Meraki SSID integrates with an enterprise RADIUS server for user-based access control?
- WPA2-Personal (PSK)
- WPA2-Enterprise (802.1X) (Correct answer)
- Open with MAC filtering
- Meraki authentication only
Correct answer: WPA2-Enterprise (802.1X)
WPA2-Enterprise with 802.1X authentication passes credentials to a RADIUS server, enabling per-user or per-device access policies and dynamic VLAN assignment.
Question 6: What does enabling 'Client Isolation' on a Meraki SSID prevent?
- Clients from accessing the internet
- Wireless clients on the same SSID from communicating directly with each other (Correct answer)
- Clients from using the 5 GHz radio
- DHCP from assigning addresses to clients
Correct answer: Wireless clients on the same SSID from communicating directly with each other
Client isolation prevents wireless clients associated to the same SSID from sending traffic directly to other clients on that SSID, improving security in public or guest networks.
