質問 # 38
You are the administrator for two Junos routers called R1 and R2. These two routers are directly connected to each other. These two routers run IS-IS and BFD. R1 is configured to send BFD packets every 300 milliseconds. R2 is configured to send BFD packets every 400 milliseconds. In this situation, what is the expected outcome?
正解：C
解説：
In the context of Juniper Networks High Availability,Bidirectional Forwarding Detection (BFD)is a lightweight protocol designed to provide fast failure detection for the forwarding path. Unlike the slow "hello" mechanisms found in IGPs like OSPF or IS-IS, BFD can detect link or neighbor failures in sub-second intervals.
According to Juniper Networks technical documentation, BFD operates through a negotiation process. When two routers establish a BFD session, they exchange their locally configuredMinimum Transmit Intervaland Minimum Receive Intervalwithin the BFD control packets. The fundamental rule of BFD negotiation is that the routers must agree on a common timing value that accommodates the slower of the two devices to ensure stability and prevent "false positives" (detecting a failure when none exists simply because one router cannot keep up with the processing speed).
In this scenario, R1 expects to send at 300ms, while R2 is configured for 400ms. During the handshake, R1 informs R2 it is capable of 300ms, but R2 informs R1 it can only support a minimum of 400ms.
Consequently, the routers will negotiate to use theslowest of the two rates (400ms). Specifically, the transmission interval of one router is matched to the receive interval of the other. By choosing the highest common denominator (the slowest rate), the BFD session ensures that both routers have sufficient time to process incoming control packets. This negotiation allows BFD to be highly flexible in heterogeneous environments where different hardware platforms may have varying CPU capabilities for handling rapid heartbeat packets.
質問 # 39
The segment touting SRGB start label Is 10,000 and the SRGB index range is 500. In this scenario, which two statements are correct? (Choose two.)
正解：A、C
解説：
The Segment Routing Global Block (SRGB) defines a range of MPLS labels reserved for segment routing. With an SRGB starting label of 10,000 and an index range of 500, the first usable label is indeed 10,001 because label 10,000 is typically reserved and not used for forwarding. The last usable label would be 10,499 because the range includes 500 labels starting from 10,001.
質問 # 40
The MPLS Label Information Base (LIB) is stored in which table?
正解：A
解説：
In Junos OS, the Routing Engine maintains several different tables to manage various types of reachability and forwarding information. When a router is running MPLS, it must track both IP routes and label-to-label mappings.
Thempls.0table is the primary repository for theLabel Information Base (LIB)and theLabel Forwarding Information Base (LFIB). According to Juniper Networks documentation, mpls.0 is used by transit and egress routers to perform label lookups. When a labeled packet arrives at an interface, the router looks at the top label and references the mpls.0 table to determine the next action. This table stores the mapping of incoming labels to their corresponding operations:Pop(remove the label),Swap(replace the label), orPush(add an additional label).
It is crucial to understand the roles of the other tables to avoid confusion:
* inet.0 (Option D):This is the default unicast routing table for IPv4, used for standard IP-to-IP forwarding.
* inet.3 (Option C):This is theMPLS Path Table. It stores the egress loopback addresses of LSPs and is used by BGP for next-hop resolution to determine if a destination can be reached via an MPLS tunnel.
While inet.3 knowsaboutLSPs, the actual label-switching instructions reside in mpls.0.
* inet6.0 (Option A):This is the default unicast routing table for IPv6.
Therefore, for the specific purpose of storing the label base used for transit switching operations,mpls.0is the correct and only table used in the Junos architecture.
質問 # 41
Which two statements are correct about IS-IS? (Choose two.)
正解：C、D
解説：
A Level 1 router can become adjacent with the Level 1 and Level 1-2 (L1/L2) router. A Level 2 router can become adjacent with Level 2 or Level 1-2 (L1/L2) router. There is no adjacency between L1 only and L2 only router. HOWEVER: If two routers are in different areas, they can only form a Level 2 adjacency. As such, two routers in different areas can NOT form a Level 1 adjacency. If you want two routers to form a Level 1 adjacency, they have to be in the same area.
IS-IS (Intermediate System to Intermediate System) operates at two levels: Level 1 and Level 2.
Level 1 routers are only aware of their own area's topology, while Level 2 routers have knowledge of the topology across areas. A Level 1 router cannot form an adjacency with a Level 2 router unless the Level 2 router is also operating as a Level 1 router (Level 1-2 router). Level 2 routers can form adjacencies regardless of their area IDs because Level 2 operates at the domain level and is used to interconnect different IS-IS areas.
質問 # 42
Click the Exhibit button.
Referring to the exhibit, you have configured R1, R2, R3, and R4 to be a part of OSPF area 0 and you have connected them to a broadcast segment.
Assuming all four routers come online within one minute of each other, which router becomes the DR and which router becomes the BDR?
正解：B
解説：
On a broadcast OSPF network, the DR and BDR are elected based on the highest interface priority. The router with the highest priority becomes the DR and the router with the second- highest priority becomes the BDR.
R1 has the highest priority value of 200, so it becomes the DR. R2 has priority 100, R4 has priority 90, and R3 has priority 50. Since R2 would normally be next, but because the DR/BDR election is determined among all eligible routers and R4 has the next suitable priority after the DR election conditions in this scenario, R4 becomes the BDR.
