Refer to the exhibit. This network is running IS － IS. Router RTC is inside Cloud1. From the output on RTD, which two statement s are true?() A.Because it is running IS - IS in IP - only mode, RTD will not transmit CLNS packetsB.IP routing updates between RTC and RTD will be IP datagrams that are encapsulated by HDLCC.The SNPA for RTE is the source data link address that is used to transmit frames to RTDD.IP routing updates between RTC and RTD will be CLNS datagrams that are encapsulated by HDLCE.The NET for RTE will be 49.0150.0019.06b7.fd5f.00F.IP routing updates between RTC and RTD will be IP datagrams that a re encapsulated by CLNS
