NEW QUESTION # 196
Your switches are managed using Junos Space Network Director. You want to secure the switches using a Network Director filter profile. A filter profile containing one term shown in the exhibit is deployed to ports on managed devices.
Which traffic will be accepted by the filter?
Answer: B
NEW QUESTION # 197
Click the Exhibit button. An OSPF broadcast segment has four routers with roles as shown in the exhibit. R1 is currently offline, and default OSPF settings are in place.
In this scenario, what happens when R1 comes back online?
Answer: A
Explanation:
OSPF's Designated Router election, as defined in RFC 2328 and implemented unchanged in Junos, is explicitly non-preemptive. Router priority is used only at the moment an election actually takes place -- that is, when no DR or BDR currently exists on the segment. Once a DR and BDR have been elected and are functioning, a router with a numerically higher priority that joins the segment afterward does not trigger a new election and does not displace the incumbent DR or BDR, no matter how much higher its priority value is. In this scenario, R2 (priority 150) and R3 (priority 100) were already elected DR and BDR respectively while R1 was offline. When R1, whose priority of 200 would have made it the preferred DR had it been present during the original election, returns to the segment, it simply forms a full adjacency with the existing DR and BDR and takes on the DROther role like R4, without any re-election occurring. This design choice exists specifically to prevent unnecessary and disruptive Network LSA regeneration and adjacency churn every time a high-priority router reboots or rejoins a stable broadcast network.
The only ways R1 could become DR going forward are if the current DR fails (promoting the BDR to DR and triggering a new BDR election) or if the entire segment's OSPF process is restarted, forcing a fresh election from a clean state.
NEW QUESTION # 198
Which IS-IS TLV should be used to advertise information about the router's neighbors and link metrics?
Answer: D
Explanation:
TLV 22, the Extended IS Reachability TLV defined in RFC 5305, is the modern and Junos-preferred mechanism for advertising a router's adjacent neighbors together with the metric associated with each link. It carries the seven-octet system ID and pseudonode number of each neighbor along with a 24-bit wide metric field, and supports an extensible set of sub-TLVs used for traffic-engineering data such as interface and neighbor IP addresses, bandwidth, and administrative groups. The original IS Reachability TLV, TLV 2, defined in the base ISO 10589 standard, carries similar neighbor and metric information but is constrained to a 6-bit narrow metric with a maximum value of 63, which is inadequate for expressing meaningful cost differentiation in modern, high-capacity enterprise and service-provider topologies; consequently, Junos deployments are commonly configured for wide-metrics-only, favoring TLV 22 over the legacy TLV 2 whenever traffic-engineering-capable or simply more granular metric representation is desired. TLV 132, the IP Interface Address TLV, only advertises the IPv4 addresses configured on the originating router's interfaces and carries no neighbor-adjacency or metric information. TLV 129, the Protocols Supported TLV, merely lists which network-layer protocols (such as IPv4 or IPv6) the originating router is capable of routing, and likewise has nothing to do with neighbor reachability or link cost.

NEW QUESTION # 199
A GRE tunnel is experiencing fragmentation issues. You confirm that the tunnel is up and is functioning correctly. You confirm that hosts are sending 1500-byte packets.
In this scenario, which statement is correct?
Answer: A
Explanation:
GRE encapsulation adds a fixed 24 bytes of overhead to every packet it carries - 4 bytes for the GRE header itself and 20 bytes for the new outer IPv4 delivery header. When a host transmits a full 1500-byte Ethernet payload into a gr- interface, the resulting encapsulated packet becomes 1524 bytes, which exceeds the physical interface's standard 1500-byte MTU and forces fragmentation or drops if the don't-fragment bit is set.
The correct remediation is to reduce the effective MTU seen by end hosts so that encapsulated packets never exceed the physical link's transmission limit. Junos automatically applies this logic to gr- logical interfaces, which default to a 1476-byte protocol MTU (1500 minus 24), but when the underlying physical interface or a manually configured path is involved, administrators must explicitly size the interface MTU to 1476 bytes to prevent post-encapsulation oversize packets. Allowing fragmentation with clear-dont-fragment is a workaround that increases CPU load and can degrade performance rather than solving the root cause, BFD addresses link-failure detection rather than MTU sizing, and ToS copying affects only the type-of-service byte, not packet length.

NEW QUESTION # 200
Click the Exhibit button. You have three Juniper Networks EX Series Switches in an STP domain as shown in the exhibit. Which statement describes the switch that will be elected as the root bridge?
Answer: C
Explanation:
Root bridge election in Spanning Tree Protocol is governed entirely by the Bridge Identifier, an 8- byte value formed by concatenating the configured bridge priority (the higher-order, more significant portion of the comparison) with the switch's MAC address (used strictly as a tiebreaker when priorities are identical). Every participating switch compares Bridge IDs, and the switch advertising the numerically lowest Bridge ID is elected root. In this exhibit, the three switches have distinctly different priority values -- EX-1 at the Junos/IEEE default of 32768, EX-2 at 8192, and EX-3 at 16384 -- meaning the comparison is decided entirely at the priority stage and never needs to proceed to a MAC address tiebreak at all. Since 8192 is numerically the lowest of the three priority values, EX-2 is elected root bridge purely on the strength of its lower priority, regardless of what its MAC address happens to be. This is precisely why the correct answer cites priority rather than MAC address as the deciding factor: MAC address only becomes relevant as a tiebreaker in the specific case where two or more switches share an identical priority value, which is not the situation presented here. Understanding that priority is evaluated first and is independently sufficient to decide the outcome whenever it differs is a foundational and heavily tested Spanning Tree concept on the JNCIS-ENT exam.
