What is the range of values from which an ISP can assign a private AS number?

Which configuration will enable the CK1 router in the AS51003 sub-AS (member-AS) as a route reflector with neighbors 10.1.1.1 and 10.2.2.2 as its route-reflector clients?

What do the following commands accomplish?
router(config-router)#neighbor {ip addressII} route-map {name} out router(config)#route-map {name} permit 10
router(config-route-map)#set as-path prepend {AS-Number} {AS-Number}

Exhibit:

Which two configuration commands will complete the BGP configuration on Domain 1 so it will conditionally announce the 172.0.0.0/8 to Domain 4 via BGP? (Choose two) hostname Domain 1

Given the AS-path of (51002 51003) 51001 i from the show ip bgp output, what is the origin?

Based on this configuration, which two peering router neighbor statements are correct? (Choose two.)
router bgp 50001
neighbor 192.168.1.1 remote-as 50001
neighbor 10.1.1.1 remote-as 50002
neighbor 10.1.1.1 local-as 50003

Refer to the show outputs in the exhibit. R1 is using a route-map to perform AS-path prepending for only a set of prefixes. When the route-map is applied, R1 only sends the prefixes with the AS-path prepended. All other prefixes in the BGP table are no longer advertised out to the BGP neighbor.What is causing this problem?
Exhibit:

If there is no exact match in the local routing table, what three conditions would result in BGP introducing the classful network 172.0.0.0 with the mask 255.0.0.0 into the BGP table? (Choose three.)

Refer to the BGP configurations and the show outputs in the diagram. What are two reasons why the 197.1.0.0/16 and 192.168.1.0/30 prefixes are not in the BGP table of WGR1? (Choose two.)
Exhibit:

Refer to the exhibit. Service provider A (AS 123) has an EBGP session to Domain where the AS number 65053 is used at Domain ‘s end. Service provider B (AS 234) also has an EBGP session to Domain where the AS number 65286 is used at Domain ‘s end. The customer decides to use AS 65053 internally. All router BGP configuration lines have 65053 as the AS number. The customer uses AS number 65286 only when establishing the EBGP session to AS 234. In this case, which is the correct configuration?
