B. With the same configuration of each port, the Ethemet 1/0/6 port is the aggregate group Unselected port
C. With the same configuration of each port, SWA randomly selects one of the 7 ports as the aggregate group Unselected port
D. With the same configuration of each port, the Ethemet1/0/1 port is the aggregation group Unselected port

A. NAT64
B. IPv6 over IPv4
C. Dual Stack
D. ISATAP
The following is an error in the OSPF routing calculation (single choice).
A. Compared to the PRC algorithm, the ISPF algorithm only calculates the changed leaf nodes when the route changes PRC algorithm to recalculate routes
B. When the first and second class LSAs on the network change, OSPF uses the ISPF algorithm to recalculate the routes The
C. OSPF router uses the FULL SPF algorithm to calculate all nodes in the network when initially calculating routes
