                                                                          2. There is a new HW office that needs to use their router as a DHCP server.

                                                                          A) Configure the startup file of the DHCP server

                                                                          A) Provide a built-in policer to limit the maximum available bandwidth of low latency queues during congestion

                                                                          C) It indicates that the reference CR is used to calculate the burst size of the built-in policer token bucket.

                                                                          4. If the OSPF protocol is running on the network, configure the non-backbone area in the OSPP area as the LSA with the ls-id of 0.0.0.0 in the Totally Stub Totally Stub area. Which LSA does the LSA belong to?
