Juniper JN0-423 free dumps (Part 2, Q41-Q70) V8.02 are below for checking 30 more demo questions:

group_vars/

4. A YANG model needs a reusable custom type named interface-name so multiple leaves can reference the same type definition.

Which statement should define it?

typedef

grouping

container

notification

5. A network management system sends an SNMP request to a Junos device. The administrator wants Junos to run local automation logic and return customized operational information through SNMP.

Which script type fits this use case?

Commit script

SNMP script

6. A JSNAPy test checks whether expected BGP neighbors are established and whether required routes exist after a maintenance window.

What is JSNAPy primarily validating?

Whether Ansible Vault can decrypt passwords

Whether a .proto file compiles successfully

Whether Junos operational state matches expected conditions

Whether Terraform can lock state

7. A Junos commit script detects that a required firewall filter is missing and returns an error during commit processing.

What is the expected result?

The device automatically reboots

The commit is rejected until the configuration is corrected

The script runs only after the commit succeeds

The event policy is disabled

8. An engineer uses gNMIc to retrieve the current value of a Junos interface counter one time. The engineer does not want continuous updates or a long-running telemetry stream.

Which gNMI operation should be used?

Get

Set

Subscribe

Commit

9. A multi-vendor automation platform needs to collect BGP state from Junos and non-Junos devices using a consistent model-driven schema.

Which model family best supports this requirement?

Junos event policy

OpenConfig

Ansible inventory

JSNAPy operator

10. A Junos administrator wants to enforce a rule that every firewall filter must include a required logging term. If the term is missing, the configuration must be rejected before becoming active.

Which script type should be used?

Event script

Commit script

Op script

SNMP script

11. An engineer subscribes to Junos telemetry using gNMIc. The collector connects successfully, but the returned data does not match the expected vendor-neutral model used by the operations platform.

What should the engineer verify first?

Whether Ansible Vault is enabled

Whether the subscription uses the intended OpenConfig path

Whether an op script is executable

Whether Terraform state locking is active

12. A developer is building an automation client that communicates with a Junos-related gRPC service. The service requires efficient binary serialization and typed messages.

Which technology is most directly associated with this requirement?

YAML inventory

Jinja2 rendering

Protocol Buffers

Junos event policy

13. An Ansible playbook must target only Junos devices in the edge group and use variables associated with that group.

Which Ansible component defines the device group membership?

Jinja2 template

Inventory

gNMI path

YANG module

14. A YANG model needs a reusable custom type for interface names so multiple leaves can reference the same type definition.

Which statement should be used?

typedef

container

notification

list

15. An Ansible repository contains Junos device credentials used by several playbooks. The team wants to keep the values encrypted while still allowing playbooks to reference them at runtime.

Which feature should be used?

Jinja2 filters

JSNAPy operators

OpenConfig paths

Ansible Vault

16. A network automation repository stores Junos login credentials used by Ansible playbooks. The team wants those credentials encrypted in the repository but still usable during playbook execution.

Which feature should be used?

Jinja2 inheritance

Ansible Vault

JSNAPy tests

OpenConfig typedefs

17. Before a maintenance window, a team captures BGP neighbor state, interface status, and route counts from Junos devices. After the change, they compare the results to expected values.

Which tool is most appropriate?

Terraform

Ansible Vault

JSNAPy

Protocol Buffers

18. A telemetry pipeline collects Junos metrics and needs to store them as time-series data before Grafana displays them.

Which TIG stack component performs the storage function?

Telegraf

Grafana

gNMIc

InfluxDB

19. A YANG model contains the following simplified structure:

container interfaces {

list interface {

key "name";

leaf name {

type string;

}

}

}

What does the key "name" statement indicate?

The name leaf uniquely identifies each list entry

The name leaf stores the telemetry sample interval

The name leaf imports another YANG module

The name leaf encrypts interface configuration

20. An engineer needs to retrieve the current value of an OpenConfig interface counter from a Junos device one time. The engineer does not want to create a telemetry stream or receive continuous updates.

Which gNMI operation should be used?

Subscribe

Set

Get

Commit

21. A Junos device should collect diagnostic output automatically when an interface-down event occurs. The action should be triggered by the event itself.

Which combination best fits this requirement?

Commit script triggered by candidate configuration

SNMP script triggered by Ansible inventory

Jinja2 template triggered by Vault

Event policy triggering an event script

22. An Ansible playbook renders Junos interface configuration from a Jinja2 template. Interface names are correct, but VLAN IDs are wrong for one site.

What should the engineer check first?

The gRPC service definition

The site-specific host_vars or group_vars

The Grafana dashboard query

The SNMP script output

23. An engineer uses gNMIc to subscribe to Junos interface statistics. Authentication succeeds, but no data is returned.

Which item should be verified first?

Whether the selected gNMI path is supported by the device

Whether Ansible Vault is enabled

Whether Terraform state locking is active

Whether an op script is executable

24. A multi-vendor automation platform needs to collect interface state from Junos and non-Junos devices using a consistent vendor-neutral data model.

Which model family best fits this requirement?

Native Junos CLI hierarchy

OpenConfig

Ansible inventory

SNMP event policy

25. A Junos telemetry pipeline uses Telegraf to collect metrics and Grafana to display dashboards. The design also requires a time-series database to store collected metrics.

Which TIG stack component provides that storage?

gNMIc

JSNAPy

Ansible inventory

InfluxDB

26. A Junos device streams telemetry data only when subscribed interface counter values change. The operations team does not want updates at a fixed interval when values remain unchanged.

Which gNMI subscription mode best matches this requirement?

ONCE

POLL

SAMPLE

ON_CHANGE

27. A YANG model contains an interface configuration node that stores a single IP address value.

Which YANG construct should this node most likely be?

container

list

leaf

grouping

28. A team wants to organize reusable Ansible content for Junos automation, including tasks, templates, defaults, files, and handlers.

Which Ansible structure is most appropriate?

Inventory group

Role

.proto package

gNMI path

29. A developer builds a gRPC automation interface. The service methods and request/response message structures must be defined in a shared file used by both client and server.

Which file type is most directly involved?

YAML inventory file

Jinja2 template file

.proto file

JSNAPy snapshot file

30. An automation workflow loads configuration changes onto Junos devices, validates the candidate configuration, and commits only if validation succeeds. If validation fails, the active configuration must remain unchanged.

Which Junos behavior makes this workflow possible?

Candidate configuration and explicit commit model

TIG metric collection and dashboarding

SNMP trap forwarding

YANG module import priority
