You are deploying OSPF in a Juniper EX Series switch stack that connects to a service provider. The provider requires that your OSPF process not send any external LSAs into the provider's area, and that your internal routers not receive external LSAs from the provider. You need to configure the OSPF area on your edge router to prevent Type-5 LSAs from being flooded into the area. Which OSPF area type should you configure?
You are configuring OSPF on a Juniper Networks router. You want to ensure that the router never becomes the designated router (DR) on a broadcast network, but it can still become the backup designated router (BDR). Which configuration statement accomplishes this?
You are configuring OSPFv3 on a Juniper SRX Series firewall to support IPv6 routing. You need to enable OSPFv3 on an interface and ensure that it participates in the correct area. Which two configuration steps are required to enable OSPFv3 on a specific interface in Junos? (Choose two.)
You are configuring an OSPF NSSA on a Juniper Networks router. You want to prevent the ABR from translating Type-7 LSAs into Type-5 LSAs because another ABR is already performing the translation. Which configuration statement should you use?
You are troubleshooting an OSPF network. Router R1 is not receiving Type-3 summary LSAs from Area Border Router (ABR) R2 for a specific area. R2 is configured with the following: set protocols ospf area 1 stub. What is the most likely reason for the missing Type-3 LSAs?
You are configuring OSPF on a Juniper router that connects to a non-broadcast multi-access (NBMA) network. The network does not support multicast, so you must manually configure neighbors. You want to minimize the number of adjacencies formed while ensuring full reachability. Which OSPF network type should you configure on the interface?
You are configuring OSPF on a Juniper Networks router. You want to change the OSPF hello interval on interface ge-0/0/0.0 to 5 seconds. Which configuration statement accomplishes this?
An administrator needs to filter Type-3 LSAs entering an OSPF stub area on a Junos routing device. Which statement under the area hierarchy is required?

You are configuring an OSPF NSSA and want to suppress the translation of Type-7 LSAs into Type-5 LSAs on one of the ABRs because another ABR is already performing the translation. Which statement is used?

You manage a Juniper Networks enterprise network using OSPF. Router R1 and Router R2 are connected via a point-to-point link. R1 is configured with the interface ge-0/0/0.0 in area 0 with a hello interval of 10 seconds and a dead interval of 40 seconds. R2 has the same interface in area 0 but with a hello interval of 30 seconds and a dead interval of 120 seconds. After configuration, the OSPF adjacency does not form. Which action will resolve the issue?

What is the most likely cause?
