QUESTION 767
Which two statements about the MAC address table space are true? (Choose two.)
A. |
You can disable learning on a VLAN to reduce table-space requirements. |
B. |
When you disable learning on a VLAN with an SVI, IP packet flooding in the Layer 2 domain is also disabled. |
C. |

D. |
The default setting for static MAC addresses to age out of the MAC address table is 300 seconds. |
E. |
Turning off MAC learning on VLANs 900 through 1005 disables learning on VLANs 900 through 1001. |
Correct Answer: AE

C. |
When a route reflector reflects a route to a client, it transmits the next hop unchanged. |
D. |
The next hop in an eBGP peering is the loopback address of the interface that originated the route. |
E. |
The next hop in an eBGP peering is the loopback address of the neighbor that announced the route. |
