An engineer configured a Cisco router to send reliable and encrypted notifications for any events to the management server. It was noticed that the notification messages are reliable but not encrypted. Which action resolves the issue?

1. A. Configure all devices for SNMPv3 informs with priv.
2. B. Configure all devices for SNMPv3 informs with auth.
3. C. Configure all devices for SNMPv3 traps with auth.
4. D. Configure all devices for SNMPv3 traps with priv.

Correct Answer: A
SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send acknowledgments when this device receives traps.”Send reliable and encrypted notifications for any events” so it is SNMP notifications. For encryption we need to configure “priv”.

An engineer is trying to redistribute OSPF to BGP, but not all of the routes are redistributed. What is the reason for this issue?

1. A. By default, only internal routes and external type 1 routes are redistributed into BGP
2. B. Only classful networks are redistributed from OSPF to BGP
3. C. BGP convergence is slow, so the route will eventually be present in the BGP table
4. D. By default, only internal OSPF routes are redistributed into BGP

Correct Answer: D
If you configure the redistribution of OSPF into BGP without keywords, only OSPF intra-area and inter-area routes are redistributed into BGP, by default.
You can redistribute both internal and external (type-1 & type-2) OSPF routes via this command: Router(config-router)#redistribute ospf 1 match internal external 1 external 2
