In computer networking a multicast address is an identifier for a group of hosts that have joined amulticast group. Multicast addressing can be used in the Link Layer （OSI Layer 2）， such as Ethernet Multicast， as well as at the Internet Layer （OSI Layer 3） as IPv4 or IPv6 Multicast. Whichtwo descriptions are correct regarding multicast addressing？（）A、The first 23 bits of the multicast MAC address are 0x01-00-5E. This is a reserved value thatindicates a multicast applicationB、The last 3 bytes （24 bits） of the multicast MAC address are 0x01-00-5E. This is a reservedvalue that indicates a multicast applicationC、To calculate the Layer 2 multicast address， the host maps the last 23 bits of the IP address intothe last 24 bits of the MAC address. The high-order bit is set to 0D、The first 3 bytes （24 bits） of the multicast MAC address are 0x01-00-5E. This is a reservedvalue that indicates a multicast application
What is the purpose of the WLC Controller-Multicast-IGMP Timeout feature operating on v5.2?（）A、to determine if there are more clients that are using the multicast streamB、to limit the time that a client has to request an IGMP join to the controller multicast groupC、to determine if the multicast router is still alive and responding to multicast clientsD、to remove clients from the multicast group if the multicast traffic exceeds the allotted bandwidth allowed for multicast clients
What are three valid match criteria in a firewall filter applied to a Layer 3 interface?（）A、IP addressB、MAC addressC、protocolD、portE、session ID
You suspect that a hacker may be performing a MAC address flooding attack somewhere within the network. Which description correctly describes a MAC address flooding attack？（）A、The attacking device spoofs a source MAC address of a valid host currently in the CAM table. The switch then forwards frames destined for the valid host to the attacking device.B、Frames with unique， invalid destination MAC addresses flood the switch and exhaust CAM table space. The result is that new entries cannot be inserted because of the exhausted CAM table space， and traffic is subsequently flooded out all ports.C、The attacking device crafts ARP replies intended for valid hosts. The MAC address of the attacking device then becomes the destination address found in the Layer 2 frames sent by the valid network device.D、The attacking device crafts ARP replies intended for valid hosts. The MAC address of the attacking device then becomes the source address found in the Layer 2 frames sent by the valid network device.E、The attacking device spoofs a destination MAC address of a valid host currently in the CAM table. The switch then forwards frames destined for the valid host to the attacking device.F、Frames with unique， invalid source MAC addresses flood the switch and exhaust CAM table space. The result is that new entries cannot be inserted because of the exhausted CAM table space， and traffic is subsequently flooded out all ports.G、None of the other alternatives apply
Which two multicast modes are valid options for use with Ethernet bridging on a mesh AP?（）A、mesh bridge inB、regularC、bi-directional bridgeD、inE、out
