질문 # 51
Which statement describes the additional overhead added when a packet is encapsulated in a GRE tunnel?
정답：C
설명：
A GRE-encapsulated packet consists of the original passenger packet wrapped inside a GRE header and a new outer IP delivery header, and the combined size of these two additions is what constitutes GRE's per-packet overhead. The base GRE header, as defined in RFC 2784 and used in its minimal, non-keyed, non-checksummed form (the default and most common deployment), is exactly 4 bytes in length, containing the flags/version field and the protocol type field identifying the encapsulated payload's ether type. Layered around that GRE header is a completely new outer IPv4 header, which itself consumes a standard 20 bytes, containing the tunnel source and destination addresses used for delivery across the underlying network. Adding these two components together -- 4 bytes for the GRE header plus 20 bytes for the new outer IPv4 header -- yields a total of exactly 24 bytes of overhead imposed on every encapsulated packet, which is precisely why Junos automatically sets the default protocol MTU on gr- tunnel interfaces to 1476 bytes (1500 minus 24) to prevent oversized, post-encapsulation packets from requiring fragmentation on a standard 1500-byte Ethernet path. The 20-byte figure alone describes only the new IP header in isolation and omits the GRE header itself, while 12 and 32 bytes do not correspond to any standard, non-keyed GRE encapsulation configuration and are included purely as plausible-looking distractors.
질문 # 52
Which two statements describe OSPF DR and BDR behavior? (Choose two.)
정답：A,B
설명：
The Backup Designated Router exists specifically to provide immediate failover redundancy for the Designated Router role on a multi-access broadcast or NBMA segment: the BDR maintains full adjacencies with every other router on the segment concurrently with the DR, precisely so that if the DR ever fails or is withdrawn, the BDR can be promoted directly to DR essentially instantaneously, without needing to wait through a fresh, full DR/BDR election process, and a new BDR election then takes place separately among the remaining DROther routers to fill the now-vacant backup role. This immediate promotion behavior confirms the first statement as correct. The Designated Router's other core responsibility on the segment is originating the Type
2 Network LSA, which describes the multi-access network itself as a pseudonode, listing every router attached to that segment; this LSA type exists specifically to avoid the full-mesh explosion of Router LSA adjacency listings that would otherwise be needed to describe a shared broadcast segment, and only the DR -- never the BDR, and never any DROther -- is responsible for generating and maintaining this particular LSA under normal, stable conditions, which confirms the third statement while directly ruling out the fourth. There is no such thing as the DR 'electing' an area border router; ABR status is instead a role a router acquires organically by having interfaces in more than one OSPF area, entirely independent of any DR/BDR election process on any individual segment.
질문 # 53
Referring to the exhibit, which router will become the OSPF BDR if all routers are powered on at the same time?
정답：D
설명：
Priority set to 0 will never become DR or BDR so R1 is excluded.
Higher priority is better in OSPF so R2 is lowest than both R3 and R4.
R3 and R4 has the same priority so RID will decide.
R4 has the highest RID so it will become DR and R3 will then become BDR.
질문 # 54

Which two statements about the IS-IS output shown in the exhibit are correct? (Choose two.)
정답：A,B
설명：
This detailed adjacency output shows R3 maintaining four separate, fully Up adjacencies, evenly split between the two IS-IS levels. R1 and R2 are both formed at Level 1, confirming that R3 is directly adjacent to exactly two Level 1 neighbors within its local area, which validates that statement. R4 and R5 are both formed at Level 2, and Level 2 adjacencies are, by definition, part of the IS-IS backbone that interconnects areas; a router maintaining any Level 2 adjacency is by that fact participating in and connected to the Level 2 backbone, confirming R3's backbone connectivity as well. Every one of the four listed adjacencies explicitly shows 'Speaks: IP, IPv6' in its detail output, which is Junos's way of indicating that both the IPv4 and IPv6 address families have been successfully negotiated and are active over that circuit; this directly contradicts, rather than supports, the claim that IPv6 is disabled on these neighbors - if IPv6 were disabled, the Speaks field would list only IP. Regarding authentication, the output contains no field, flag, or indication whatsoever referencing authentication configuration or state for the R5 adjacency (or any adjacency); Junos would typically surface authentication-related information separately if it were configured and relevant, and its complete absence here means no basis exists in the exhibit to conclude authentication is required for that specific adjacency. Reference topics: Junos Enterprise Routing - IS-IS, Level 1 and Level 2 Adjacencies and Address Family Negotiation.
질문 # 55
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.)
정답：A,B
설명：
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. Reference topics: Junos Enterprise Routing - High Availability, Nonstop Active Routing Requirements and GRES Dependency.
