Sure, I'd be happy to provide a detailed explanation of the answer choices for this Juniper Networks Certified Associate Junos exam question.
The correct answers are: A. The BGP import policy accepts all BGP routes. C. The OSPF import policy accepts all OSPF routes.
Here's an explanation of each answer choice:
A. The BGP import policy accepts all BGP routes: By default, Junos devices will accept all BGP routes received from BGP peers. This means that all BGP routes will be installed into the device's routing table, unless a specific import policy is configured to filter out certain routes. This default behavior is useful because it ensures that all BGP routes are available for use, but it can also lead to a large number of routes being installed in the routing table, which can consume resources.
B. The BGP export policy rejects all active BGP routes: This answer choice is incorrect because it describes a policy that is not a default policy on Junos devices. By default, there is no BGP export policy configured, which means that all BGP routes are available for export to BGP peers.
C. The OSPF import policy accepts all OSPF routes: Similar to BGP, Junos devices will by default accept all OSPF routes received from OSPF neighbors. This means that all OSPF routes will be installed into the device's routing table, unless a specific import policy is configured to filter out certain routes. This default behavior is useful because it ensures that all OSPF routes are available for use, but it can also lead to a large number of routes being installed in the routing table, which can consume resources.
D. The OSPF export policy accepts all active OSPF routes: This answer choice is incorrect because it describes a policy that is not a default policy on Junos devices. By default, there is no OSPF export policy configured, which means that all OSPF routes are available for export to OSPF neighbors.
I hope this explanation helps clarify the correct answers for this Juniper Networks Certified Associate Junos exam question!
