13. Frage
Which statement correctly describes the purpose of Bidirectional Forwarding Detection (BFD) in Junos OS?
Antwort: B
Begründung:
Bidirectional Forwarding Detection (BFD) is a lightweight protocol used to rapidly detect failures in the forwarding path between two adjacent devices, typically much faster than a routing protocol's native hello/dead timer mechanism. BFD can be associated with multiple routing protocols, such as OSPF, BGP, and static routes, to trigger faster reconvergence upon detecting a failure.
14. Frage
An update to your organization's network security requirements document requires management traffic to be isolated in a non-default routing-instance. You want to implement this requirement on your Junos-based devices.
Which two commands enable this behavior? (Choose two.)
Antwort: B,C
Begründung:
Explanation
To isolate management traffic in a non-default routing-instance on Junos-based devices, you can use the set system management-instance and set routing-instances mgmt_junos commands12.
set system management-instance: This command associates the management interface (usually named fxp0 or em0 for Junos OS, or re0:mgmt-* or re1:mgmt-* for Junos OS Evolved) with the non-default virtual routing and forwarding (VRF) instance1. After you configure the non-default management VRF instance, management traffic no longer has to share a routing table with other control traffic or protocol traffic1.
set routing-instances mgmt_junos: This command creates a new routing instance named mgmt_junos. The name of the dedicated management VRF instance is reserved and hardcoded as mgmt_junos; you cannot configure any other routing instance by the name mgmt_junos1.
Therefore, options C and D are correct. Options A and B are not correct because they attempt to assign an interface to the mgmt_junos routing instance, which is not necessary for isolating management traffic1.
15. Frage
You are using tunnels in your network. It is important that the routes be specific enough to ensure that the tunnels are established. You need to prevent a route that is new to the network from being used.
In this scenario, which type of route should be used?
Antwort: B
16. Frage
Exhibit:
When trying to commit the configuration shown in the exhibit, you receive an error.
What is the problem?
Antwort: B
Begründung:

17. Frage
Exhibit
Referring to the exhibit, which two configuration changes must you apply for packets to reach from R1 to R3 using IS-IS? (Choose two.)
Antwort: A,C
Begründung:
Explanation
A: On R1, enable Level 1 on the ge-0/0/1 interface. In IS-IS, both levels (Level 1 and Level 2) are enabled by default when you enable IS-IS on an interface1. Level 1 systems route within an area2. If the destination is outside an area, Level 1 systems route toward a Level 2 system2. Therefore, enabling Level 1 on the ge-0/0/1 interface on R1 would allow packets to reach from R1 to R3.
D: On R3 enable Level 1 on the ge-0/0/4 interface Similarly, enabling Level 1 on the ge-0/0/4 interface on R3 would allow packets to reach from R1 to R3.
These explanations are based on the IS-IS configuration documents and learning resources available at Juniper Networks1 and Cisco34.
