A. B. C. D. E.BE.
The given configuration on RA router specifies the management-plane inband interface TenGigE 0/0/0/0 to allow SSH traffic from a specific IPv4 address range 5.0.0.0/8.
Based on this information, the correct statements are:
B. SSH connections coming through TenGigE 0/0/0/0 from 5.5.5.5 host are accepted: Since the configuration specifies that the TenGigE 0/0/0/0 interface allows SSH traffic from the IPv4 address range 5.0.0.0/8, any SSH connections from the specific host 5.5.5.5 would be accepted.
D. Telnet connections coming through MgmtEth0/RSP0/CPU0/0 interface are accepted: The given configuration does not mention anything about the MgmtEth0/RSP0/CPU0/0 interface. However, since it is the default management interface for Cisco IOS XR routers, it is likely that Telnet connections coming through this interface would be accepted.
The other statements are incorrect because:
A. SNMP traps going out on TenGigE 0/0/0/0 interface are dropped: The configuration only specifies SSH traffic from a specific IPv4 address range. It does not mention anything about SNMP traps going out on the TenGigE 0/0/0/0 interface. Therefore, it cannot be determined whether they would be dropped or not.
C. TACACS traffic going through TenGigE 0/0/0/0 interface are dropped: The configuration only specifies SSH traffic from a specific IPv4 address range. It does not mention anything about TACACS traffic going through the TenGigE 0/0/0/0 interface. Therefore, it cannot be determined whether it would be dropped or not.
E. SNMP polling coming through TenGigE 0/0/0/0 interface are dropped: The configuration only specifies SSH traffic from a specific IPv4 address range. It does not mention anything about SNMP polling coming through the TenGigE 0/0/0/0 interface. Therefore, it cannot be determined whether it would be dropped or not.
