TheClient Isolationfeature on RUCKUS access points and controllers prevents wireless clients connected to the same SSID from communicating directly with each other within the same subnet. This is particularly important for guest or public networks to enhance security and privacy. However, administrators may sometimes need to allow access to specific network services or devices—such as printers, gateways, or media servers—within that same subnet.

RUCKUS systems address this need through theIsolation Whitelistcapability. As described in theRUCKUS One Online HelpandRUCKUS Cloud documentation, theIsolation Whitelistallows administrators to specify destination IP or MAC addresses that are exempt from client isolation rules. This enables controlled access without fully disabling client isolation across the network.

Other options likedirected multicastoraccess control list (ACL)manage traffic types or filtering policies but are not specific to client-to-client communication exceptions. Therefore, theIsolation Whitelistis the correct answer.

RUCKUS indoor Access Points usestatus LEDsto communicate key operational states during deployment and runtime. The LEDs provide immediate visual feedback about the AP’s connectivity, power condition, and client activity.

According to theRUCKUS One Online Help – Access Point LED Indicators, and verified in theRUCKUS AI documentation, the LEDs typically display the following primary states:

Controller Connected (A):Confirms that the AP has successfully registered and established a control session with the RUCKUS controller or RUCKUS Cloud instance.

Insufficient PoE Power (C):Indicates that the AP is receiving inadequate power, such as being powered through 802.3af instead of 802.3at, which may disable high-power features or additional radios.

Clients Connected to a Radio (D):Lights up when one or more clients are associated with the AP’s wireless radios, signifying active WLAN operation.

Other listed options—USB dongle inserted,data plane tunnel connected, androutable IP assigned—are not standard LED indications across RUCKUS indoor AP models. They may represent system events but not physical LED states.

When deployingSmartZone-Essentials (SZ-100/SZ-144)forRUCKUS ICX switch management, the switches establish a secure HTTPS-based connection to the controller using theSmartZone registrar IP. A common issue preventing connection occurs whenSmartZone is not configured to accept self-signed certificates—which are typically used by ICX switches by default for initial onboarding.

As described in theRUCKUS One Online Help – SmartZone Switch Management SetupandRUCKUS AI documentation, administrators must explicitly enable the option to“Allow Self-Signed Certificates”in the controller’sSwitch Management settings. Without this configuration, the SmartZone rejects the ICX connection request during SSL/TLS handshake, causing registration failure.

SNMPv3 configuration and DHCP options are unrelated to initial controller registration. Additionally,SmartZone-Essentialsfully supports ICX management;SmartZone High Scaleis not required.

Thus, the correct answer isC— the connection fails because the controller is not set to accept self-signed certificates from the switch.
