RCNI Sample Questions & Answers

A network team is deploying 802.1X port-based authentication in a mixed-vendor environment. They want to ensure that if a user successfully authenticates on an ICX switch port, the RADIUS server can assign them to a specific VLAN for their user role. Which two RADIUS attributes are commonly used to achieve this dynamic VLAN assignment? (Select TWO).

A retail company is setting up a new warehouse using ICX 7150-C12P compact switches. To prevent unauthorized devices from connecting and gaining network access, the administrator implements port security with a mac-address-table static entry and the port-security maximum 1 command on an interface. What happens when a second, unknown device is connected to this secured port?

A consultant is reviewing the Spanning Tree Protocol (STP) configuration on a campus network. They notice that a specific access layer switch unexpectedly becomes the root bridge for a VLAN, causing suboptimal traffic paths. To prevent this switch from ever becoming the root bridge, which STP feature should be enabled on its designated ports that connect to the distribution layer?

A systems administrator is configuring a new ICX 7450 switch. They need to set up a syslog server to collect critical event logs. The command logging __________ is used to specify the destination for these logs. What should be entered in the blank to send logs to a server with the IP address 192.168.10.25?

A university is deploying RUCKUS access points that require PoE+ (802.3at) power. An ICX 7150-48PF switch is selected. According to the product specifications, what is the total PoE power budget available on this specific switch model?

A network engineer is configuring two geographically separate data centers connected by a WAN link. They are using OSPF as the routing protocol on their ICX 7850 routers. To optimize routing and reduce the size of the routing table, they want to summarize routes from several /24 networks within Data Center A before advertising them to Data Center B. Which type of OSPF router is responsible for performing this route summarization between areas?

During a network audit, a security analyst discovers that DHCP starvation attacks are possible on the guest VLAN. To mitigate this, the network administrator decides to implement DHCP Snooping. Which of the following describes the primary function of a trusted port in a DHCP Snooping configuration?

Case Study: Global Logistics Firm Network Upgrade

Company Background:
Global Transport Inc. (GTI) is a logistics company with a central headquarters (HQ) and multiple large distribution centers. They are undertaking a major network refresh to improve performance and security. The core of their network at HQ is being upgraded to a pair of ICX 7850 switches configured for redundancy. The distribution centers use ICX 7450 stacks as their local core/aggregation layer.

Current Situation:
GTI's network has grown organically and suffers from slow convergence times during link failures, leading to disruptions in their critical package tracking system. The current routing is managed by a legacy EIGRP implementation, which is not supported on the new ICX switches. All inter-site connectivity is handled via private MPLS links provided by a carrier.

Technical Requirements:

1. Implement a standards-based, fast-converging interior gateway protocol (IGP) across the entire enterprise.
2. Ensure high availability for the default gateway at all distribution centers. The solution should provide sub-second failover.
3. Prevent routing loops and ensure that routes learned from the MPLS carrier do not interfere with the internal routing domain.
4. All network management must be performed from a dedicated, out-of-band management VLAN (VLAN 99).

Problem:
An implementation engineer at GTI needs to select the most appropriate protocols and features to meet the technical requirements on the new RUCKUS ICX infrastructure. Which of the following solution proposals BEST addresses all the specified requirements?

A technician is troubleshooting a link between two ICX switches that is not passing traffic. The show interface command on Switch A shows the port is Up, Line protocol is down (err-disabled). Further investigation reveals the error is bpdu-guard-shutdown. What is the most likely cause of this issue?

A network administrator needs to select an appropriate RUCKUS ICX switch for a new office building's access layer. The requirements are: support for at least 24 PoE+ devices, 10GbE uplinks to the core, and stacking capabilities for simplified management. Which ICX product family is specifically designed for this campus edge role?
