   An engineer notices that OSPF adjacencies on a slow, high-latency WAN link are flapping because hello packets are being dropped. The engineer wants to make the adjacencies more stable without changing the physical link. Which configuration change on the OSPF interface would directly address this issue?

   • ADecrease the hello interval and the dead interval on the interface.
   • BIncrease the hello interval and the dead interval on the interface.
   • CIncrease the retransmit interval on the interface.
   • DSet the interface to passive mode.

   An engineer is troubleshooting an OSPF adjacency that will not come up between two Junos routers on a point-to-point link. The engineer has verified that both routers have the same area ID and that the interfaces are up. Which operational command would directly reveal a mismatch in the OSPF hello or dead interval?

   • Ashow ospf database
   • Bshow ospf interface
   • Cshow route protocol ospf
   • Dshow ospf neighbor

   Which OSPF configuration statement prevents hello packets from being sent on a specific interface while still allowing the interface's subnet to be advertised as an OSPF route?

   • Aset protocols ospf no-hello interface ge-0/0/0.0
   • Bset protocols ospf disable interface ge-0/0/0.0
   • Cset protocols ospf passive interface ge-0/0/0.0
   • Dset protocols ospf interface ge-0/0/0.0 passive

   An OSPF area 1 contains 100 /28 subnets. The network team wants to reduce the number of Type 3 LSAs advertised into area 0 by summarizing these subnets into a single /22 route. Which configuration on the ABR is required?

   • AConfigure a static route for the /22 prefix and redistribute it into OSPF.
   • BAdd a 'generate' route for the /22 prefix and apply it as an export policy on OSPF.
   • CUse a routing policy to reject the individual /28 routes on the ABR.
   • DAdd a 'route-summary' statement for the /22 prefix under the 'area 1' configuration.
