質問 # 19
Which feature allows Junos OS to perform recursive lookups for static route next hops?
正解：B
解説：
The resolve option enables recursive next-hop resolution for static routes in Junos OS. When configured, the router performs a lookup in the routing table to determine how to reach the specified next-hop address, allowing the next hop to be resolved through another route instead of requiring it to be directly connected.
質問 # 20
Exhibit:
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：C
解説：
In OSPF networks, when multiple routers are connected to a shared multi-access broadcast segment (like an Ethernet switch), they undergo an election process to select aDesignated Router (DR)and aBackup Designated Router (BDR). This mechanism is essential for reducing the number of adjacencies and limiting the volume of Link State Advertisement (LSA) flooding on the segment.
The OSPF election process follows a strict hierarchy based on the following criteria:
* Interface Priority:The router with the highest OSPF interface priority is elected as the DR. The router with the second-highest priority becomes the BDR. In Junos, the default priority is 128, but it can be manually configured between 0 and 255.
* Router ID:If there is a tie in priority, the router with the numerically highest Router ID (RID) wins the election.
Analyzing the configuration provided in the exhibit:
* R1:Priority 200, Router-ID 192.168.1.1
* R2:Priority 100, Router-ID 192.168.1.2
* R3:Priority 50, Router-ID 192.168.1.3
* R4:Priority 90, Router-ID 192.168.1.4
Comparing the priority values,R1 has the highest priority (200)and therefore becomes theDR. The next highest priority value among the remaining routers is100, which belongs to R2, making it theBDR. Although R4 has a higher Router ID than R2, the priority value is evaluated first and takes precedence.
Since all routers came online within a short window (one minute), they participate in the same election cycle, ensuring the configured priorities dictate the outcome rather than "first-come, first-served" preemption behavior common in OSPF once a DR is already established.
質問 # 21
Click the Exhibit button. Referring to the exhibit, which two statements are true? (Choose two.)
正解：B、C
解説：
The configuration places the interface in VLAN membership for VLAN ID 10, meaning it is part of the VLAN that uses VLAN ID 10. With ethernet-switching and VLAN membership specified, the port expects frames associated with that VLAN, which are carried as tagged frames for that VLAN.
質問 # 22
How are routing loops prevented in external BGP networks?
正解：B
解説：
BGP is apath-vector protocol, and its primary mechanism for ensuring a loop-free topology across the global internet is theAS_PATHattribute. This attribute is a "well-known mandatory" attribute that records every Autonomous System (AS) a prefix has passed through.
According to Juniper Networks Service Provider documentation, the loop prevention rule forExternal BGP (EBGP)is straightforward: when a router receives a BGP Update from an EBGP peer, it examines the AS_PATH list. If the router's ownlocal AS numberis already present in the list, it indicates that the advertisement has already traversed the local AS and has returned. To prevent a routing loop, the routerwill not use the routeand will implicitly discard the update (Option D).
This behavior is a default, hard-coded function of the BGP protocol and does not require the administrator to write manualrouting policies(Options B and C) to achieve basic loop prevention. While there are advanced features like as-path-expand or allow-as-in that can modify this behavior for specific design requirements (such as in certain Hub-and-Spoke MPLS VPN topologies), the standard operational default is to reject any route where the local AS is detected in the path. This ensures that traffic does not circulate infinitely between Autonomous Systems.
質問 # 23
Referring to the exhibit, from which device(s) does R3 learn about Route X?
正解：D
解説：
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.
