Every day we are learning new knowledge, but also constantly forgotten knowledge before, can say that we have been in a process of memory and forger, but how to make our knowledge for a long time high quality stored in our minds? This requires a good memory approach, and the JN0-352 study braindumps do it well. The JN0-352 prep guide adopt diversified such as text, images, graphics memory method, have to distinguish the markup to learn information, through comparing different color font, as well as the entire logical framework architecture, let users on the premise of grasping the overall layout, better clues to the formation of targeted long-term memory, and through the cycle of practice, let the knowledge more deeply printed in my mind. The JN0-352 Exam Questions are so scientific and reasonable that you can easily remember everything.
NEW QUESTION # 36
You have configured a GRE tunnel from your local router with tunnel source 10.0.0.1 to a remote router at destination 192.168.0.1. The tunnel is functioning until you commit set routing-options static route 0.0.0.0/0 next-hop gr-0/0/0. This configuration causes the tunnel to go down.
Which statement is correct in this scenario?
Answer: D
Explanation:
A GRE tunnel's outer, delivery-layer packets are forwarded using the router's ordinary underlay routing table, meaning the tunnel destination address (192.168.0.1 in this case) must itself be resolvable to a physical, non- tunnel next hop for the encapsulated packets to actually leave the router. Before this configuration change, the default route (or some more specific route) presumably pointed toward a real physical next hop, allowing the router to reach 192.168.0.1 and keep the tunnel operational. When the administrator commits a static default route of 0.0.0.0/0 with a next hop of gr-0/0/0, every destination lookup that previously fell back to the default route - including the lookup for the tunnel's own destination address, 192.168.0.1, since no more specific route exists for it - now recurses through the GRE interface itself. This creates a circular dependency: the router needs to route to 192.168.0.1 to keep the tunnel up, but the only route it has to reach 192.168.0.1 now points back into the tunnel that requires 192.168.0.1 to already be reachable, so the interface's next-hop resolution fails and the tunnel drops. This is an entirely valid and common GRE design pitfall rather than any platform restriction; GRE interfaces can be legitimately used as static route next hops, do not require loopback-sourced encapsulation, and do not require a /32 host route to resolve their destination, provided that route does not recursively point back through the tunnel.

NEW QUESTION # 37
You want to use filter-based forwarding (FBF) to forward traffic sourced from subnet 10.0.0.0/24 to a specific destination.
Which two routing instance types would enable you to accomplish this task? (Choose two.)
Answer: A,B
NEW QUESTION # 38
Which two fields must match in an OSPF hello packet to form an adjacency over a broadcast link? (Choose two.)
Answer: A,D
Explanation:
RFC 2328 specifies a precise set of parameters that two OSPF routers on a broadcast network must agree upon before a valid neighbor relationship can be established, and a mismatch in any of these mandatory fields causes the routers to reject each other's Hello packets outright rather than forming even a basic 2-Way state. The network mask carried in each Hello packet must match between neighbors on a broadcast segment, since OSPF uses this field to confirm both routers agree on the subnet boundaries of the shared segment; a mismatched mask (for example, one router configured with a /24 and its neighbor with a /25 on the same physical wire) is treated as a configuration error and blocks adjacency formation. The router dead interval, which defines how long a router will wait without receiving a Hello before declaring a neighbor down, must likewise match exactly between neighbors, alongside the closely related hello interval, since these timers govern the shared expectations both sides have for how frequently Hellos should arrive and how quickly a failure should be detected; Junos explicitly checks and rejects Hello packets carrying a mismatched dead interval value. Router priority, by contrast, is intentionally allowed to differ between neighbors on the same segment -- it exists precisely so that administrators can differentiate router preference for the DR/BDR election, and differing values are expected and normal rather than being blocked. The designated router field, as advertised within each Hello, is informational about the sender's current view of the segment's DR and is not a value that must be identical between the two Hello senders to permit adjacency formation.
NEW QUESTION # 39
You are asked to deploy nonstop active routing (NSR) on a dual-Routing Engine platform. In this scenario, what are two additional requirements for proper operation? (Choose two.)
Answer: A,D
Explanation:
Nonstop active routing is specifically engineered to be completely transparent to the rest of the network:
rather than relying on neighboring routers to preserve state during a Routing Engine switchover the way graceful restart does, NSR keeps a fully synchronized instance of the routing protocol process (rpd) running continuously on the backup Routing Engine, mirroring protocol adjacencies, the RIB, and session state in real time. Because neighbors never observe a session reset or restart signal during an NSR-driven switchover, there is no dependency on those neighbors supporting or enabling graceful restart extensions at all - this is the core architectural advantage that distinguishes NSR from GR and is precisely why the first and third answer choices are incorrect distractors. What NSR does require locally is Graceful Routing Engine Switchover (GRES) enabled first, since NSR is built as an extension on top of GRES and depends on it to synchronize kernel and interface state between the two Routing Engines before protocol-level synchronization can occur. Additionally, Juniper's official guidance mandates that both Routing Engines run the identical Junos OS software version; mismatched versions between the primary and backup Routing Engine can introduce incompatible internal data structures or feature behavior during state replication, jeopardizing the integrity of a switchover and is explicitly called out as a hard operational requirement rather than a mere best practice.
