What are three extended BGP communities? (Choose three.)

- D. target:65000:65000
- E. domain-id: 192.168.1.1:555
Answer: B,D,E
Explanation:
The BGP extended communities attribute format has three fields:
type: administrator: assigned-number. type is the type of extended community and can be either the 16-bit numerical identifier of a specific BGP extended community or one of these types:
origin-- Identifies where the route originated.
domain-id-- Identifies the OSPF domain from which the route originated.
target-- Identifies the destination to which the route is going.
bandwidth-- Sets up the bandwidth extended community. Specifying link bandwidth allows you to distribute traffic unequally among different BGP paths.
rt-import-- Identifies the route to install in the routing table.
src -as-- Identifies the AS from which the route originated.
You must specify an AS number, not an IP address.

NEW QUESTION 58
Which two statements about RSTP are correct? (Choose two.)

- D. RSTP permits only a single root bridge within a Layer 2 domain.
Answer: B,C
Explanation:
B: RSTP and STP can co-exist. RSTP achieves its rapid converges over STP through new mechanisms. If a RSTP switch connects to an STP switch, the RSTP switch will drop down to STP convergence speeds on a per-port basis.
C: Unlike 802.1d (STP), 802.1w (RSTP) uses Hello packets between bridges to maintain link states and does not rely on the root bridge.
