Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) 認定 JN0-351 試験問題 (Q119-Q124):

質問 # 119
You manage the Layer 2 network shown in the exhibit. You experience a failure on the ge-0/0/0 link between Switch-1 and Switch-2.

Which statement is correct about the expected behavior?

A. Switch-2 will become the root bridge for a separate RSTP topology
B. Switch-2's ge-0/0/2 port role and state will remain as designated and forwarding
C. Switch-2 will remove itself from the RSTP topology
D. Switch-2's ge-0/0/2 port role and state will transition to root and forwarding

正解：D

質問 # 120
Which statement is correct about the configuration shown in the exhibit?

A. The ge-0/0/0 and ge-0/0/1 interfaces are operating in trunk mode.
B. The ge-0/0/2 interface is operating as a Layer 3 interface.
C. The configuration will not complete the commit check process and will error out.
D. All three interfaces are operating in access mode.

正解：D

質問 # 121
Exhibit

You have configured a GRE tunnel. To reduce the risk of dropping traffic, you have configured a keepalive OAM probe to monitor the state of the tunnel; however, traffic drops are still occurring.
Referring to the exhibit, what is the problem?

A. The " event link-adjacency-loss " option must be set.
B. The hold-time value must be two times the keepalive-time value
C. For GRE tunnels, the OAM protocol requires that the BFD protocols also be used.
D. LLDP needs to be removed from the gr-1/1/10.1 interface.

正解：B

解説：
A keepalive OAM probe is a mechanism that can be used to monitor the state of a GRE tunnel and detect any failures in the tunnel path. A keepalive OAM probe consists of sending periodic packets from one end of the tunnel to the other and expecting a reply. If no reply is received within a specified time, the tunnel is considered down and the line protocol of the tunnel interface is changed to down 1 .
To configure a keepalive OAM probe for a GRE tunnel, you need to specify two parameters: the keepalive- time and the hold-time. The keepalive-time is the interval between each keepalive packet sent by the local router. The hold-time is the maximum time that the local router waits for a reply from the remote router before declaring the tunnel down 2 .
According to the Juniper Networks documentation, the hold-time value must be two times the keepalive-time value for a GRE tunnel 2 . This is because the hold-time value must account for both the round-trip time of the keepalive packet and the processing time of the remote router. If the hold-time value is too small, it may cause false positives and unnecessary tunnel flaps.
In the exhibit, the configuration shows that the keepalive-time is set to 10 seconds and the hold-time is set to
15 seconds for the gr-1/1/10.1 interface. This means that the local router will send a keepalive packet every 10 seconds and will wait for 15 seconds for a reply from the remote router. However, this hold-time value is not two times the keepalive-time value, which violates the recommended configuration. This may cause traffic drops if the remote router takes longer than 15 seconds to reply.
Therefore, option D is correct, because the hold-time value must be two times the keepalive-time value for a GRE tunnel. Option A is incorrect, because BFD is not required for GRE tunnels; BFD is another protocol that can be used to monitor tunnels, but it is not compatible with GRE keepalives 3 . Option B is incorrect, because the "event link-adjacency-loss" option is not related to GRE tunnels; it is an option that can be used to trigger an action when a link goes down 4 . Option C is incorrect, because LLDP does not need to be removed from the gr-1/1/10.1 interface; LLDP is a protocol that can be used to discover neighboring devices and their capabilities, but it does not interfere with GRE tunnels 5 .

質問 # 122
You have configured the four EX Series switches with RSTP, as shown in the exhibit. You discover that whenever a link between switches goes up or down, the switches take longer than expected for RSTP to converge, using the default settings.
In this scenario, which action would solve the delay in RSTP convergence?

A. The hello-time must be increased.
B. The max-age must be increased to 20
C. The force-version must be removed.
D. The bridge priority for EX-4 must be set at 4000.

正解：C

解説：
The exhibit shows the configuration of RSTP on EX-4, which has the command force-version stp.
This command forces the switch to use the legacy STP protocol instead of RSTP, even though the switch supports RSTP. This means that EX-4 will not be able to take advantage of the faster convergence and enhanced features of RSTP, such as edge ports, link type, and proposal/agreement sequence. The other switches in the network are likely to be running RSTP, as it is the default protocol for EX Series switches. Therefore, there will be a compatibility issue between EX-4 and the other switches, which will result in longer convergence times and suboptimal performance. The switch will also generate a warning message that says "Warning:
STP version mismatch with neighbor" when it receives a BPDU from a RSTP neighbor.
To solve this problem, the force-version command must be removed from EX-4, so that it can run RSTP natively and interoperate with the other switches in the network. This will enable faster convergence and better stability for the network topology. To remove the command, you can use the delete protocols rstp force-version command in configuration mode.

質問 # 123
You are asked to explore adding BGP route reflectors to allow for increased scale in your core network. Which statement is correct in this scenario?

A. The cluster ID is not required to use route reflectors.
B. Route reflectors require that the network is connected in a physical full mesh.
C. The cluster ID is required to prevent routing loops.
D. Route reflectors are required whenever internal BGP (IBGP) sessions are needed.

正解：C
