NEW QUESTION # 198
Which two fields must match in an OSPF hello packet to form an adjacency over a broadcast link? (Choose two.)
Answer: B,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 # 199
Referring to the exhibit, why is this OSPF adjacency remaining in this state?
Answer: D
Explanation:
OSPF stuck in ExStart is mainly related to mismatched MTU. It could also be caused by a firewall filter on the loopback interface, but this is not an alternative.
NEW QUESTION # 200
You are establishing a new BGP session to an EBGP peer using loopback addresses. In addition to your general EBGP settings, which BGP feature must be enabled for this session to establish?
Answer: C
Explanation:
By default, EBGP sessions are built with the expectation that peers are directly connected at Layer 3, and Junos enforces this by sending EBGP packets with a TTL of 1. When loopback addresses are used as the session endpoints instead of the directly connected physical interface addresses, the resulting IP packets must traverse at least one additional router hop between the two loopbacks, and a TTL of 1 will expire in transit before reaching the remote loopback, causing the TCP handshake -- and therefore the BGP session -- to fail even though a valid route to the peer's loopback exists. The multihop statement (configured as an EBGP multihop parameter with an accompanying TTL value, most commonly set to 2 for a single intermediate hop) instructs Junos to increase the TTL used for that peer's BGP packets so they survive the extra hop count between loopbacks. This is a mandatory addition any time an EBGP session is deliberately built against non-directly-connected addresses, whereas IBGP sessions, by contrast, do not have this default restriction because IBGP already assumes peers may be multiple hops apart within the same AS. Multipath affects load-balancing across equal-cost paths, damping suppresses flapping routes, and passive controls whether a router waits for the remote peer to initiate the TCP connection -- none of these resolve the TTL expiration problem inherent to loopback-based EBGP peering.
NEW QUESTION # 201
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.
NEW QUESTION # 202
Which statement describes how a generated route determines its next hop?
Answer: D
Explanation:
A generate route is a specialized type of Junos summary route that, unlike an aggregate route, is permitted to inherit and use an actual forwarding next hop rather than being restricted to reject or discard. When multiple contributing routes exist beneath the summarized prefix, Junos selects one of them as the primary contributor using a deterministic process: it first evaluates route preference (choosing the contributor with the lowest, most preferred value), then breaks any remaining tie by preferring the contributing route with the numerically lowest metric, and continues through further tie-breaking criteria if necessary until a single primary contributor is identified. The generate route then adopts the next hop of that specific primary contributor as its own forwarding next hop, meaning traffic matching the generate route but not matching any individual contributing route is forwarded toward whichever real next hop the primary (best) contributing route currently uses. This behavior is fundamentally different from an aggregate route, which never adopts a forwarding next hop at all and instead installs with a reject (or optionally discard) next hop by default, deliberately preventing traffic from being forwarded toward a next hop that might not actually lead to the intended more-specific destination. There is no mechanism by which the next hop is chosen arbitrarily from the 'first' or 'least- specific' contributor, and while a next hop can be manually overridden under the generate route's own configuration, that is not the default resolution behavior being described here.
