Question 157

The following description of the process of sending and receiving data frames in switch interface Access mode is correct? ( Single choice questions).

In Access mode, labeled data frames are discarded directly when they are received.

Access mode strips off the VLAN tag of the dataton when sending .

Access mode receives only unlabeled data frames.

When a data frame enters the switch interface, the switch learns the destination MAC address in the data frame.

Question 159

The OSPF3 protocol is a separately developed protocol that differs somewhat from OSPF2 in that OSPFv3 is link-based rather than network segmented, and the following statement is incorrect?().

Single choice questions).

Two OSPF routers connected to the link can establish a neighbor relationship even if their IPv6 address prefixes are different

The routing information obtained by the B. OSPFv3 router from the neighbor uses the neighbor's Link-Local address as the next hop in the forwarded packet

For two OSPF routers connected to the link, you can establish a neighbor relationship even if you do not configure a unicast IPv6 address

All OSPFv3 interfaces use the Link-Local address as the destination address of the message
