A network engineer is configuring a new Juniper router for OSPF. The router has the following interfaces: lo0.0 = 10.255.255.1/32, ge-0/0/0.0 = 172.16.1.1/30, and ge-0/0/1.0 = 192.168.1.1/30. The engineer wants to ensure the router ID is 10.255.255.1. What is the most reliable way to achieve this?

Ensure the loopback interface is active and has the highest IP address

Configure a manual router ID using 'set protocols ospf router-id 10.255.255.1'

Disable OSPF on all physical interfaces

Set the router ID at the routing-options level

A service provider is designing a new OSPF network and needs to ensure that each router has a unique identifier within the OSPF domain. The network will consist of Juniper MX routers. What is the primary purpose of the OSPF router ID?

To identify the router in the OSPF domain and to source OSPF packets

To specify the OSPF version running on the router

To determine the OSPF area that the router belongs to

To set the OSPF cost for all interfaces on the router

A network engineer is planning to change the router ID on a router that is the designated router (DR) on a broadcast segment. The change will be done during a maintenance window. What is the most important consideration for this change?

The change will be transparent to the network and no disruption will occur

The change will only affect the DR/BDR election, not the adjacencies

The change will cause all adjacencies to reset, potentially causing a brief routing disruption

The change will only affect the router's own database, not its neighbors

A network engineer is reviewing the OSPF configuration on a Juniper router. The router has a manual router ID configured as 10.255.255.1. The router also has a loopback interface with address 10.0.0.1/32 and a physical interface with address 192.168.1.1/30. What will be the OSPF router ID?

The router ID will be randomly assigned

Part of the Open Shortest Path First (OSPF) domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–1 from this objective — we provide 14 practice questions to prepare you well beyond it.

A network engineer is preparing a new Juniper MX router for deployment in an OSPF area. The router has the following IP addresses configured: ge-0/0/0.0 = 10.0.1.1/30, lo0.0 = 192.168.1.1/32, and ge-0/0/1.0 = 172.16.0.1/30. No manual router ID has been configured. Which IP address will the router select as its OSPF router ID?
