It covers basic networking troubleshooting techniques and procedures for performing ICX switch recovery. Candidates should be able to identify and resolve common network issues in ICX environments.

Topic 4

Foundational Networking Concepts: This section of the exam measures the skills of RUCKUS ICX Network Administrators and covers essential networking concepts. It includes VLAN design and configuration, STP and loop prevention protocols, PoE requirements, basic LAN concepts, Layer 3 routing configurations, and basic QoS concepts. Candidates should be able to demonstrate proficiency in designing VLANs for network segmentation.

RUCKUS Certified Networking Implementer Sample Questions (Q50-Q55):

NEW QUESTION # 50
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. Local username/password is only used for SSH and web access.
C. The AAA web-server configuration is missing the radius keyword.
D. Based on the AAA login command, local password will only be used if the RADIUS server is unavailable.

Answer: D

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 # 51
What are two features of Open Shortest Path First (OSPF)? (Choose two.)

A. calculates link cost
B. updates routes dynamically
C. utilizes distance vector
D. automatic redistribution of routes
E. uses exterior gateway protocols

Answer: A,B

Explanation:
Open Shortest Path First (OSPF) is a widely used interior gateway protocol (IGP) designed for routing within an autonomous system (AS). It is a link-state routing protocol that offers several key features:
Key Features of OSPF:
* Calculates Link Cost:
* OSPF assigns a cost to each link, representing the overhead required to send packets across that link. The cost is typically based on the link's bandwidth; higher bandwidth links have lower costs.
* OSPF uses these costs to calculate the shortest path to each network destination, ensuring efficient routing.
* Updates Routes Dynamically:
* OSPF routers exchange link-state advertisements (LSAs) to share information about network topology changes.
* When a change occurs, such as a link failure, OSPF quickly propagates this information, allowing routers to update their routing tables dynamically and converge on a new optimal topology.
Clarifications on Other Options:
* Option A: Utilizes distance vector
* OSPF is a link-state protocol, not a distance vector protocol. Distance vector protocols, like RIP, use different mechanisms for route calculation.
* Option C: Automatic redistribution of routes
* OSPF does not automatically redistribute routes from other routing protocols. Route redistribution between different protocols requires manual configuration.
* Option E: Uses exterior gateway protocols
* OSPF is an interior gateway protocol (IGP) used within a single autonomous system, not an exterior gateway protocol (EGP) like BGP, which is used between autonomous systems.

Answer: C

NEW QUESTION # 53
Which three conditions allow an ARP request or response to pass a Dynamic ARP Inspection (DAI) check?
(Choose three.)

A. There is a static reservation for the IP/MAC pair in the DHCP pool.
B. Client authenticated using RADIUS on an 802.1X enabled port.
C. Client authenticated using MAC authentication.
D. The IP/MAC pair appear in the DHCP binding database.
E. Request originated on a trusted port.
F. A static ARP entry exists for the IP/MAC pair with the inspection flag set.

Answer: D,E,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.
