NEW QUESTION # 28
Which two Power over Ethernet (PoE) features on the ICX will be enabled by the inline power poe-ha command? (Choose two.)
- A. power priority
- B. PoE Overdrive
- C. Fast Boot
- D. power limit
- E. Perpetual PoE
Answer: C,E
Explanation:
The inline power poe-ha command on RUCKUS ICX switches enables two key Power over Ethernet (PoE) features:
* Fast Boot PoE: This feature ensures that PoE power is delivered to connected devices immediately upon switch startup, without waiting for the entire system to boot up. This is crucial for devices that need to be operational as soon as possible, such as IP phones or security cameras. To enable Fast Boot PoE, enter interface configuration mode and execute the command:
inline power poe-ha
This command ensures that PoE is delivered promptly during the boot process.
* Perpetual PoE: This feature maintains PoE power to connected devices even when the switch undergoes a soft reboot or firmware upgrade. It ensures uninterrupted power delivery, preventing devices from losing power during such events. To enable Perpetual PoE, use the same command in interface configuration mode:
By configuring this command, the switch provides continuous PoE power during reboots.
For more detailed information on these features and their configuration, refer to the RUCKUS Community Forum post titled "Things to consider about PoE at a glance, when deploying." Ruckus Wireless Community

NEW QUESTION # 30
What is the maximum Wattage for a PoE+ interface with PoE overdrive enabled?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
Power over Ethernet (PoE) technology allows network switches to deliver electrical power to connected devices over standard Ethernet cables. The IEEE 802.3at standard, commonly known as PoE+, provides up to
30 watts of power per port. RUCKUS enhances this capability with a proprietary feature called PoE+ Overdrive, which increases the maximum power output per port.
With PoE+ Overdrive enabled, a PoE+ interface on RUCKUS ICX switches can deliver up to 45 watts of power over two pairs of wires. This enhancement is particularly beneficial for devices that require more power than the standard PoE+ provision, such as advanced wireless access points or video conferencing systems.
It's important to note that the actual power delivered to the powered device (PD) is slightly less due to cable losses. For instance, while the Power Sourcing Equipment (PSE) may supply 45 watts, the PD might receive approximately 35.5 watts. This ensures that devices receive sufficient power even after accounting for transmission losses.
The availability of PoE+ Overdrive and the maximum power output per port can vary depending on the specific ICX switch model. For example, the RUCKUS ICX 7650 supports PoE+ Overdrive with a maximum output of 45 watts per port. Similarly, the ICX 7150-48ZP model offers PoE+ Overdrive capabilities.
For detailed information on PoE+ Overdrive capabilities and supported models, refer to the "Ruckus Power over Ethernet (PoE) Interoperability" document.

NEW QUESTION # 32
Review the following configuration.
A RADIUS server is connected and working. However, a switch technician has forgotten the RADIUS username/password for the ICX. When RADIUS is not functioning, they expect to be able to plug into the console port and use the local username/password as a backup.
The ICX does not accept the local password.
Why can't the technician log in?
- A. Based on the AAA login command, local should be in front of radius for correct backup operation.
- B. Based on the AAA login command, local password will only be used if the RADIUS server is unavailable.
- C. Local username/password is only used for SSH and web access.
- D. The AAA web-server configuration is missing the radius keyword.
Answer: B
Explanation:
* Understanding the Configuration:
* The command aaa authentication login default radius local specifies that the switch will attempt RADIUS authentication first. If the RADIUS server is unavailable, it will fallback to the local username/password.
* If the RADIUS server is operational, the local credentials will not be accepted, even over the console port.
* Why Can't the Technician Log In?
* The local username/password will only work if the RADIUS server is unreachable. In this scenario, the RADIUS server is functional, so the switch continues to authenticate through it and does not fall back to the local credentials.
* This behavior is by design, as dictated by the configuration.
* Solution:
* If access to the console port using local credentials is a critical requirement, consider adjusting the configuration to prioritize local credentials. For example, use:
aaa authentication login default local radius
This configuration ensures that local credentials are tried first, with RADIUS as a secondary option.

NEW QUESTION # 36
ICX reserves some VLAN IDs for system functions. How many VLAN IDs are reserved?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
In RUCKUS ICX switches, certain VLAN IDs are reserved for system functions and cannot be used for user- defined VLANs. Specifically, the following VLAN IDs are reserved:
* VLAN 0: Reserved for priority tagging.
* VLAN 1: Default VLAN for untagged frames.
* VLAN 4095: Reserved and cannot be used.
* VLAN 4094: Reserved and cannot be used.
* VLAN 4093: Reserved and cannot be used.
This totals to 5 reserved VLAN IDs.
These reservations are standard across many networking devices to ensure proper network operations and to avoid conflicts with system-level processes. It's important to note that while VLAN 1 is the default VLAN, it can be reassigned if necessary, but caution should be exercised to avoid disrupting network management and control traffic.

NEW QUESTION # 40
Why is the following command failing?
RKUS-01(config)#vlan 1
RKUS-01(config-vlan-1)#tagged ethernet 1/2/1
Invalid input -> tagged ethernet 1/2/1
Type ? for a list
- A. This model ICX does not have an interface Ethernet 1/2/1.
- B. VLAN 1 must be configured as a protocol-based VLAN before tagged ports can be added.
- C. A Virtual Ethernet interface must be defined before a tagged port can be added.
- D. The default VLAN cannot be tagged to any interfaces.
Answer: D
Explanation:
In RUCKUS ICX switches, VLAN 1 is the default VLAN and is typically used for management purposes. By default, all ports are members of VLAN 1 as untagged. Attempting to configure VLAN 1 as tagged on a port can result in an error, as the system restricts tagging the default VLAN.
Understanding the Error:
RKUS-01(config)# vlan 1
RKUS-01(config-vlan-1)# tagged ethernet 1/2/1
Invalid input -> tagged ethernet 1/2/1
Type ? for a list
This error occurs because the switch does not allow tagging of the default VLAN (VLAN 1) on any interface.
Resolution:
* Option 1: Use a Different VLAN for Tagging
* Create a new VLAN (e.g., VLAN 2) and configure it as tagged on the desired port.
RKUS-01(config)# vlan 2
RKUS-01(config-vlan-2)# tagged ethernet 1/2/1
* Option 2: Change the Default VLAN ID
* If you must use VLAN 1 as tagged, you can change the default VLAN ID to another VLAN (e.g., VLAN 2), allowing VLAN 1 to be configured as tagged.
RKUS-01(config)# default-vlan-id 2
RKUS-01(config)# vlan 1
RKUS-01(config-vlan-1)# tagged ethernet 1/2/1

NEW QUESTION # 43
Which three conditions allow an ARP request or response to pass a Dynamic ARP Inspection (DAI) check?
(Choose three.)
- A. Request originated on a trusted port.
- B. Client authenticated using MAC authentication.
- C. The IP/MAC pair appear in the DHCP binding database.
- D. There is a static reservation for the IP/MAC pair in the DHCP pool.
- E. Client authenticated using RADIUS on an 802.1X enabled port.
- F. A static ARP entry exists for the IP/MAC pair with the inspection flag set.
Answer: A,C,F
Explanation:
Dynamic ARP Inspection (DAI) is a security feature that intercepts and validates Address Resolution Protocol (ARP) packets in a network. It ensures that only legitimate ARP requests and responses are relayed, preventing ARP spoofing and man-in-the-middle attacks.
Conditions Allowing ARP Packets to Pass DAI Checks:
* IP/MAC Pair in the DHCP Binding Database:
* When DHCP snooping is enabled, the switch maintains a binding table of IP-to-MAC address mappings assigned by the DHCP server.
* DAI uses this database to verify that ARP packets have legitimate IP/MAC address pairs.
* If the ARP packet's IP/MAC pair matches an entry in the DHCP binding database, it passes the DAI check.
* Static ARP Entry with Inspection Flag Set:
* Administrators can configure static ARP entries for known devices, marking them as trusted for DAI purposes.
* These entries include the IP/MAC pair and are flagged to bypass DAI checks.
* An ARP packet matching a static entry with the inspection flag set will pass the DAI check.
* Request Originated on a Trusted Port:
* Ports can be designated as trusted, typically those connected to other switches or network devices.
* DAI does not inspect ARP packets arriving on trusted ports, assuming they are from legitimate sources.
* Therefore, ARP requests or responses from a trusted port pass the DAI check.
References:
* For more information on configuring DAI and related security features, refer to the RUCKUS FastIron Layer 3 Routing Configuration Guide: Dynamic ARP Inspection overview Implementing DAI with these conditions helps protect the network from ARP-based attacks by ensuring that only validated ARP traffic is permitted.

- B. ICX(config-vlan-2)# enable
- C. ICX(config-vlan-2)# router-interface ve 2
- D. ICX(config-vlan-2)# interface ve 2
Answer: C
Explanation:
In RUCKUS ICX switches, a Virtual Ethernet (VE) interface, also known as a routed interface, is used to route traffic between VLANs. To create a VE interface and associate it with a VLAN, follow these steps:
* Access VLAN Configuration Mode: Enter global configuration mode and then VLAN configuration mode for the desired VLAN. For VLAN 2, the commands are:
* Create and Associate VE Interface: Within VLAN configuration mode, create the VE interface and associate it with the VLAN using the router-interface command:
router-interface ve 2
This command creates VE interface 2 and links it to VLAN 2.
* Configure the VE Interface: Exit VLAN configuration mode and enter interface configuration mode for the newly created VE interface to assign an IP address:
interface ve 2
ip address <IP_address> <subnet_mask>
Replace <IP_address> and <subnet_mask> with the desired IP address and subnet mask for the VE interface.
By following these steps, you create a VE interface that enables routing for the associated VLAN. This configuration is essential for inter-VLAN routing,
