질문 # 160
Which two statements are correct about IS-IS? (Choose two.)
정답：C,D
설명：
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.
질문 # 161
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?
정답：B
설명：
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.
질문 # 162
Referring to the exhibit, from which device(s) does R3 learn about Route X?
정답：D
설명：
R2 can not forward IBGP learned routes to another IBGP neighbor correct R3 will learn about Route X from R2 only. R1 is in a separate AS and Route X is advertised to R2 through eBGP. R2 will then advertise the route to R3 using iBGP. R3 cannot learn routes directly from another AS without having a direct eBGP session with that AS.
질문 # 163
What prevents routing loops in a single-area OSPF network?
정답：A
설명：
In OSPF, loop prevention within a single area is achieved through the fundamental nature of its link-state architecture. Unlike distance-vector protocols that rely on "routing by rumor," OSPF ensures that every router within an area maintains an identicalLink-State Database (LSDB). This database acts as a complete map of the network topology.
Once the LSDB is synchronized, each router independently executes theShortest Path First (SPF) algorithm
, which is formally known as theDijkstra algorithm. This mathematical process treats the local router as the
"root" of a tree and calculates the shortest path to every other node (router) and prefix in the area based on the cumulative interface costs. Because every router uses the same synchronized map (the LSDB) and the same deterministic algorithm, they all arrive at a consistent, loop-free view of the best paths.
According to Juniper Networks technical documentation, the Dijkstra algorithm is superior to theBellman- Ford algorithm(used by distance-vector protocols like RIP) in this regard. Bellman-Ford is susceptible to
"count-to-infinity" problems and loops because routers only know the distance and direction to a destination provided by their neighbors, rather than the full topology. In OSPF, even if a link fails, the updated Link-State Advertisement (LSA) is flooded rapidly, and the Dijkstra algorithm is re-run to find a new loop-free path.
Routing policies(Option B) are used to manipulate path selection or filter routes but are not the primary mechanism for fundamental loop prevention in OSPF. Similarly,forwarding policies(Option D) govern how traffic is handled at the data plane level rather than determining the control plane's loop-free topology.
질문 # 164
You are evaluating BGP between two Juniper routers and the BGP session is stuck in the Idle state. What would cause this behavior?
정답：B
설명：
In the BGP Finite State Machine (FSM), theIdlestate is the first stage of any BGP connection. When a BGP session is "stuck" in Idle, it typically indicates that the router is unable to even begin the process of establishing a TCP connection with its neighbor. According to Juniper Networks documentation, before BGP can transition to theConnectorActivestates, it must have a valid route to the neighbor's IP address in the routing table and be able to initiate a three-way TCP handshake on port 179.
If thepeer IP address is incorrect(Option D), the router may not have a route to that destination, or it may be attempting to connect to a non-existent or unreachable host. In many Junos configurations, if the underlying IGP (OSPF/IS-IS) or static routing cannot provide reachability to the neighbor address defined in the BGP configuration, the BGP process will remain in the Idle state and periodically retry the connection.
Regarding the other options:
* The local AS number is missing (Option C):In Junos, you cannot commit a BGP configuration if the local autonomous system is not defined at either the [edit routing-options] level or within the BGP group itself. The commit check would fail before the session could even attempt to start.
* The BGP group type (Option B):Having a mismatch in group type (internal vs. external) usually results in the session reaching theOpenSentorOpenConfirmstate before failing due to an
"unacceptable AS" error in the OPEN message.
* BGP hold time (Option A):Issues with hold timers or keepalives generally cause a session that is already in theEstablishedstate to drop; they do not prevent the session from leaving the Idle state.
