Which three conditions allow an ARP request or response to pass a Dynamic ARP Inspection (DAI) check?(Choose three.)  The IP/MAC pair appear in the DHCP binding database.  A static ARP entry exists for the IP/MAC pair with the inspection flag set.  Client authenticated using MAC authentication.  Client authenticated using RADIUS on an 802.1X enabled port.  Request originated on a trusted port.  There is a static reservation for the IP/MAC pair in the DHCP pool. 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.Q15. Which statement is true about Secure Shell (SSH) functionality in FastIron 08.0.95?  Default login timeout is 30 seconds.  Default SSH authentication type is RSA with 2048-bit modulus.  Server function is disabled by default.  Outbound SSH sessions are not supported. Q16.

Which command enables global IPv6 capabilities?  ipv6 dhcp6-server enable  ipv6 unicast-routing  ipv6 multicast  ipv6 nd proxy Q18. What are two differences between Class of Service (CoS) and Differentiated Services Code Point (DSCP)?(Choose two.)  DSCP defines priority levels and CoS manipulates traffic according to these defined priority levels.  CoS defines priority levels and DSCP manipulates traffic according to these defined priority levels.  DSCP operates at Layer 2 in OSI model, whereas CoS operates in Layer 3.  CoS operates at Layer 2 in OSI model, whereas DSCP operates in Layer 3.  DSCP is simpler and can scale easily as the network grows. CoS becomes more complex as network demand for prioritized data increase. Class of Service (CoS) and Differentiated Services Code Point (DSCP) are both mechanisms used to prioritize network traffic, but they function at different layers of the OSI model and have distinct characteristics:* Operational Layer:* CoS:* Operates at Layer 2 (Data Link Layer) of the OSI model.* Utilizes a 3-bit field within the 802.1Q VLAN tag, known as the Priority Code Point (PCP), to assign priority levels ranging from 0 to 7.* DSCP:* Operates at Layer 3 (Network Layer) of the OSI model.* Uses a 6-bit field in the IP header to assign priority, allowing for up to 64 different values, providing more granularity in traffic classification.* Scalability and Complexity:* CoS:* With only 8 possible priority levels, CoS offers limited granularity.* As network demands increase, especially with diverse applications requiring different levels of service, managing and differentiating traffic with CoS can become complex due to its limited priority levels.* DSCP:* Provides 64 distinct priority levels, allowing for finer differentiation of traffic types.* This granularity enables easier scalability and more straightforward management of diverse and growing network traffic demands.References:* For a detailed comparison between CoS and DSCP, refer to the NetworkLessons Notes on QoS CoS vs DSCP: QoS CoS vs DSCP – NetworkLessons Notes* For an overview of Differentiated Services and traffic classification, see the article on GeeksforGeeks:Differentiated Services (DiffServ) and Traffic ClassificationUnderstanding these differences is crucial for network administrators when designing Quality of Service (QoS) policies to ensure efficient and effective traffic management across the network.Q19.

Which two Power over Ethernet (PoE) features on the ICX will be enabled by the inline power poe-ha command? (Choose two.)  power priority  Fast Boot  PoE Overdrive  Perpetual PoE  power limit Q34. What are two features of Open Shortest Path First (OSPF)? (Choose two.)  utilizes distance vector  calculates link cost  automatic redistribution of routes  updates routes dynamically  uses exterior gateway protocols 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.References:* OSPF Design Guide* Understanding OSPFQ35.
