The CPU of a router becomes directly involved with packet-switching decisions. maintains two tables in the data plane the FIB and adjacency table. Which DHCP option helps lightweight APs find the IP address of a wireless LAN controller? Option 43 Option 67 Option 60 Option 150 Which encryption hashing algorithm does NTP use for authentication? AES256 AES128 SSL MD5 What is the role of the RP in PIM sparse m Qode? The RP maintains default aging timeouts for all multicast streams requested by the receivers. The RP is the multicast router that is the root of the PIM-SM shared multicast distribution tree. The RP acts as a control-plane node only and does not receive or forward multicast packets The RP responds to the PIM join messages with the source of a requested multicast group. A client device fails to see the enterprise SSID, but other client devices are connected to it. What is the cause of this issue?
