Which of the following defines split horizon?
Sending routes out the interface they were learned from
Sending routes out the interface they were learned from with infinite metric
Holding a recently unreachable route in the table for a fixed time to allow other routers to be notified
Not sending routes out the interface they were learned from
When you configure RIP on a Juniper Networks router, how do you specify what interfaces the protocol should operate on?
You use a network statement with a network mask
You use a network statement with a wildcard mask
You specify interface names and logical units explicitly as part of RIP neighbor configuration
You use routing policy
None of the above
What command displays the RIP routes a Juniper Networks router is sending out to a given interface?
This is not possible given the LS nature of RIP
show route protocol rip
show route advertising-protocol rip
<neighbor>
show route receiving-protocol rip
<neighbor>
Which type of router generates a Type 2 LSA?
Internal
ABR
ASBR
DR
Which is true regarding a stub area with no-summaries?
The area uses a default to reach interarea destinations
The area imports external routes as Type 7 LSAs
The area does not receive Type 3 summary LSAs from the backbone
The area has no OSPF routers in it
When you add a new OSPF router to a LAN, what factor(s) determine whether it will become the DR?
Its priority setting
The RID
Whether any other routers are already operating on that LAN
All of the above
What determines which route will be active when a given prefix is learned by multiple routing protocols?
The lowest metric
The path with the fewest hops
The protocol with the highest numerical preference is chosen
The protocol with the lowest numerical preference is chosen
Which syntax at an ABR would suppress individual summaries for routes in the 10.0/16 block in area 1 while replacing them with a single summary?
Which is true regarding the overlay migration model?
You first set the legacy IGP to be less preferred than the new IGP
You first set the new IGP to be less preferred than the legacy IGP
Route redistribution is needed to maintain connectivity through the migration
A new backbone is needed
What is the primary mechanism for loop prevention in the redistribution model?
A common LSDB ensures a loop-free topology
Strict controls that ensure routes are not redistributed back to their originating IGP
Setting the new IGP to be more preferred than the legacy IGP
A careful mapping of metrics between originating and receiving IGPs
What types of authentication are supported in JUNOS software for OSPF?
Simple password
MD5 checksum
Hitless key chain of MD5 keys/checksums
All of the above
Which configuration will inject a default route into stub area 1?
