RUCKUS Updated RCWA Exam Questions and Answers by hashir

When enabling 802.1X authentication on a RUCKUS Access Port via an Ethernet Port Profile (used for ICX switches or AP wired interfaces), the available roles are:

(A) Supplicant: The device (AP or switch port) acts as the client that must authenticate to the upstream authenticator (e.g., a switch or NAC system).

(C) Port-based Authenticator: The device enforces 802.1X authentication for devices connected to it (e.g., a switch controlling a connected host).

According to RUCKUS One Online Help – 802.1X and Wired Authentication Configuration and RUCKUS Analytics 3.5 User Guide – Wired Client Authentication Monitoring , these two roles define whether the port initiates or enforces authentication.

“Host-based” and “MAC-based” refer to specific authentication methods , not roles , and “Authentication Server” (e.g., RADIUS) is an external entity, not a port role.

The Backup Management feature in SmartZone enables administrators to schedule automatic configuration backups at regular intervals. These backups can include cluster, zone, and AP configuration data.

As detailed in RUCKUS One Online Help – Backup and Restore Procedures , this feature supports manual and scheduled backups with options for secure off-box storage.

The RUCKUS Analytics 3.5 User Guide – Backup Compliance Monitoring notes that this ensures disaster recovery readiness and simplifies configuration rollback.

System Snapshot and Cluster Maintenance features track versioning and updates but are not used for configuration backup automation.

The Rule of 10s and 3s provides a fast approximation for converting logarithmic dBm values into absolute power in milliwatts. A 10 dB increase multiplies power by ten, while a 3 dB increase approximately doubles it. Start with the standard reference of 20 dBm = 100 mW. Because 17 dBm is 3 dB below 20 dBm, the power is approximately halved: 100 mW ÷ 2 = 50 mW. Therefore, 17 dBm corresponds to approximately 50 mW. The exact mathematical value is about 50.1 mW, so option C is also accurate beyond the quick approximation. RUCKUS technical specifications routinely express transmit and receive power in dBm while antenna gain is specified separately in dBi, making these conversions fundamental to RF planning and troubleshooting.

Auto Cell Sizing (ACS) is a RUCKUS feature designed to automatically optimize the RF environment by dynamically adjusting transmit power levels of access points to ensure balanced coverage and minimal interference between APs.

According to the RUCKUS One Online Help – RF Management and Auto Cell Sizing and RUCKUS AI documentation – RF Optimization Tools , ACS:

Automatically adjusts radio transmit power (B) based on environmental conditions and neighboring AP coverage.

Requires background scanning to be enabled (D) so the system can measure the surrounding RF conditions and interference patterns.

ACS does not automatically adjust channel selection , as that functionality is handled by ChannelFly , a separate RUCKUS technology. It is not enabled by default , and manual power tuning is typically disabled when ACS is active, since the controller manages power dynamically to maintain optimal cell overlap.

Thus, the correct answers are B (it can automatically adjust radio power) and D (it requires background scanning to be enabled).
