Juniper JN0-352 Exam Topics - You’ll Be Tested in Actual Exam
What surprises people is how often the questions start with a small Layer 2 detail and end with a routing decision, so you have to think across the box instead of in silos. You need to be comfortable with VLAN behavior and how spanning tree choices shape the paths your traffic can actually take, because a lot of later troubleshooting logic depends on that mental map. Layer 2 security shows up less as theory and more as knowing what breaks when you tighten controls and how that interacts with normal switching behavior. From there the exam spends real energy on protocol independent routing ideas that sit underneath everything, like how forwarding and route selection behave before you even argue about which dynamic protocol is in play. OSPF and IS IS are where candidates either feel at home or get exposed, since you are expected to reason about adjacencies, areas or levels, and why a route wins when multiple sources exist. BGP then pushes you to think policy first, because the right answer is often about attributes and intent rather than raw reachability. Tunnels appear as the connective tissue that changes what the underlay sees, which can quietly reshape IGP and BGP decisions. High availability is not just redundancy trivia, it is recognizing failure modes and what state does or does not survive. The trap is memorizing commands without predicting outcomes, so practice explaining to yourself what the network will do next when one link or neighbor disappears.
