| Question ID 13559 | Which two of these statements regarding RSTP are correct? (Choose two.)
|
| Option A | RSTP cannot operate with PVST+.
|
| Option B | RSTP defines new port roles.
|
| Option C | RSTP defines no new port states.
|
| Option D | RSTP is a proprietary implementation of IEEE 802.1D STP.
|
| Option E | RSTP is compatible with the original IEEE 802.1D STP.
|
| Correct Answer | B,E |
Explanation Explanation: When network topology changes, rapid spanning tree protocol (IEEE802.1W, referred to as RSTP) will speed up significantly the speed to re-calculate spanning tree. RSTP not only defines the role of other ports: alternative port and backup port, but also defines status of 3 ports: discarding status, learning status, forwarding status. RSTP is 802.1D standard evolution, not revolution. It retains most of the parameters, and makes no changes.
| Question ID 13560 | Which command can be used from a PC to verify the connectivity between hosts that
connect through a switch in the same LAN?
|
| Option A | ping address
|
| Option B | tracert address
|
| Option C | traceroute address
|
| Option D | arp address
|
| Correct Answer | A |
Explanation Explanation: ICMP pings are used to verify connectivity between two IP hosts. Traceroute is used to verify the router hop path traffic will take but in this case since the hosts are in the same LAN there will be no router hops involved.
