Which two commands can be used to display the IP address of a device attached to a switch port? (Choose two.)
Correct Answer:
D, E
Explanation
The show inline power and show inline power detail commands both display PoE power budget information on ICX switches. The first command gives a basic overview of inline power status and available budget, while detail provides more comprehensive information including per-port power consumption and remaining budget. These are the standard commands for monitoring PoE power allocation on ICX devices.
ICX reserves some VLAN IDs for system functions. How many VLAN IDs are reserved?
Correct Answer:
D
Explanation
Zero-touch stacking requires both enabling stacking on the active controller and ensuring all units have clean configurations before they can join the stack properly. A clean configuration removes any previous settings that might prevent the devices from discovering and joining each other automatically. Without both prerequisites in place, the stacking process will fail or behave unpredictably.
Which command could be used to find the system name of an attached device?
Correct Answer:
B
Explanation
When ordering a replacement power supply for an ICX7650, you must consider the voltage (110 vs 220 volt), power delivery type (DC vs AC), and whether the power supply needs to support PoE functionality. These three factors determine compatibility with your current infrastructure and deployment requirements. Getting any of these wrong means the power supply will not work with your switch.
Which switch cannot exceed a maximum of 30W per port?
Correct Answer:
C
Explanation
The inline power power-by-class 3 command provides 15.4 watts to connected PoE devices. Class 3 is the IEEE 802.3af standard classification that delivers exactly this power level. This command configures the interface to supply power according to the Class 3 specification rather than negotiating or using different power levels.
What is the maximum Wattage fur a PoE+ interface with PoE overdrive enabled?
Correct Answer:
C
Explanation
The command 'ip ospf area 0' is used to assign an interface to an OSPF area. This is a Layer 3 routing configuration task that falls under ICX Solution Implementation. When configuring OSPF on an ICX switch, you enter the interface configuration mode and then assign it to a specific OSPF area using this command. The area number determines which OSPF area the interface belongs to, which is essential for proper OSPF network segmentation and operation. This practical configuration skill is tested in the implementation domain rather than foundational concepts.
Which command will transfer a code image between flash modules, from the primary partition to the secondary partition?
Correct Answer:
B
What are two differences between Class of Service (CoS) and Differentiated Services Code Point (DSCP)? (Choose two.)
Correct Answer:
B, D
Explanation
CoS and DSCP are both QoS mechanisms but operate at different layers and serve different functions. CoS works at Layer 2 using a 3-bit field in the Ethernet frame to define priority levels for traffic. DSCP operates at Layer 3 using a 6-bit field in the IP header and actually manipulates or marks traffic according to those defined priority levels. Option B correctly identifies that CoS defines priorities while DSCP manipulates traffic based on them. Option D correctly states the layer difference. The other options misrepresent how these mechanisms work or confuse their purposes.

RCNI Exam FAQ
Common questions about the exam itself
What experience do I need before taking the RCNI exam?
You should have at least five years of network experience or exposure, with solid understanding of advanced Layer 2 and Layer 3 protocols and basic network troubleshooting skills. While the exam does not require a prior RUCKUS certification, strong foundational networking knowledge is essential to succeed.
Which objective area of RCNI is the hardest to prepare for?
ICX Solution Implementation carries the most weight at 45 percent of the exam and covers the widest range of topics. Focus on hands-on practice with ICX software management, stacking configuration, and Layer 2 and Layer 3 protocol implementation to master this domain.
How long should I prepare for the RCNI exam?
Most candidates need four to six weeks of focused preparation, though this depends on your existing network experience. Spending time on the official study guide, the ICX 150 Implementer free course from CommScope University, and hands-on lab practice will significantly improve your readiness.
What is the format of the RCNI exam?
The exam contains 60 multiple choice and scenario-based questions that you must complete in 120 minutes. Questions progress in difficulty and reflect real-world deployment and troubleshooting situations you will encounter with ICX switches in production networks.
What is the passing score for RCNI?
You need to achieve a score of 64 percent to pass the exam. This means getting approximately 38 or more of the 60 questions correct.
How much does the RCNI exam cost?
The exam fee is USD 150. Pricing may vary by region or if you purchase a training voucher bundle, so check the RUCKUS Certification Store or your regional reseller for current options.
What happens if I fail the RCNI exam?
You can retake the exam immediately once at no additional fee. After the second attempt, you must wait 14 days before retaking. From the third to fifth attempt, you must wait 30 days between retakes, with a maximum of five retakes allowed within one year. Each retake costs the standard USD 150 fee.
How long is the RCNI certification valid?
Your RCNI certification is valid for three years from the date you pass the exam. After three years, you will need to renew your certification to maintain your credential.
What role is the RCNI certification designed for?
The RCNI certification is designed for RUCKUS ICX implementers, network engineers, deployment engineers, support engineers, and sales engineers who manage, administer, or troubleshoot RUCKUS ICX networking deployments in production environments.
Is RCNI the entry-level RUCKUS wired networking certification?
Yes, RCNI is one of the foundational certifications in the RUCKUS Wired Networking track and does not require a prior RUCKUS certification to attempt. After passing RCNI, you can pursue more advanced RUCKUS certifications to deepen your expertise in specific product areas.
