NETCONF And XML API

You need to lock the candidate configuration datastore in your NETCONF script to prevent concurrent modifications by other administrators. Which XML element accomplishes this?

You need to load a set of configuration changes into the Junos candidate datastore from an inline XML string using NETCONF. Which RPC element is used to load configuration data?

Which TWO methods can an administrator use to verify that a Python script successfully established a NETCONF session with a Junos device? (Choose two)

Which Junos configuration statement enables the NETCONF service over SSH for remote automation clients?

When executing a NETCONF <get-config> request, you specify <source><candidate/></source> but omit any filtering tags. What is returned in the <rpc-reply>?

An administrator issues an edit-config RPC with default-operation="replace" targeting the candidate datastore. What is the impact on the existing configuration on the Junos device?

An engineer writes a Python script using ncclient to push changes to a Junos device. After sending the configuration via <edit-config>, the script needs to make the changes active without dropping the NETCONF session lock prematurely or requiring a separate explicit commit RPC if candidate workflows are bypassed. However, using standard candidate datastore workflow, what is the exact RPC required to activate the candidate configuration?

An engineer executes a NETCONF <discard-changes> RPC. What is the precise effect of this operation on the Junos device?

An engineer needs to establish a NETCONF session with a Junos device securely. Which underlying transport protocol does NETCONF use by default according to RFC 6242?

A network automation engineer is establishing a NETCONF session with a Junos device. After the SSH connection is established, the device and the client exchange <hello> messages. What is the primary purpose of this exchange?

An automation script uses the Junos XML API to retrieve interface statistics every 5 minutes. The script uses the <get-interface-information> RPC with the <interface-name> filter for a specific interface. After several successful runs, the script suddenly receives an empty <interface-information> element. What is the most likely cause?

Which TWO statements are true regarding NETCONF locking mechanisms on Junos devices? (Choose two)

An automation script performs a NETCONF transaction that triggers an alarm. You want to retrieve current system alarms using the Junos XML API. Which RPC tag represents this request?

Which python module is part of the standard library that can be used to parse XML responses returned by NETCONF?

A network engineer is establishing a NETCONF session with a Junos device and needs to lock the candidate configuration to prevent concurrent modifications by other administrators. Which NETCONF operation should be executed?

Which TWO actions occur during the initial NETCONF session establishment phase between a client and a Junos device? (Choose two)

Which THREE attributes are available within the <edit-config> operation element in NETCONF to specify the modification action on a target node? (Choose three)

You are writing a Python script to retrieve the operational state of interfaces from a Junos device using NETCONF. Which XML RPC element must be enclosed within the <rpc> tag to request operational data?

An automation engineer is using the Junos XML API to retrieve operational data from a device. The engineer wants to ensure that the response is well-formed XML and includes the Junos namespace so that it can be parsed correctly. Which XML namespace should the engineer expect in the response for Junos-specific operational tags?

Which THREE error-tag values defined in NETCONF RFC 6241 may be returned by a Junos device when an edit-config operation fails validation? (Choose three)

Which TWO benefits does NETCONF provide over traditional screen-scraping CLI automation? (Choose two)

Which THREE error-type values are defined in the NETCONF protocol specification (RFC 6241) for categorizing <rpc-error> messages? (Choose three)

An automation engineer is using the Junos XML API over SSH to load a configuration snippet into the candidate datastore. The engineer wants to ensure that the configuration is merged with the existing candidate configuration. Which RPC and attribute should be used?

What is the standard IETF RFC that defines the core NETCONF protocol architecture and operations?

An automation script attempts to load a configuration snippet using NETCONF <edit-config> with operation="delete" on a container statement. What happens if the specified container does not currently exist in the candidate configuration?

What is the purpose of the <hello> element exchanged immediately after establishing a NETCONF SSH session?

Which THREE distinct operational states or configuration views can be queried using specific Junos XML API RPCs? (Choose three)

Which transport protocol is mandated by RFC 6241 as the standard secure connection mechanism for NETCONF when operating in typical Junos enterprise automation environments?

You are writing a script that parses NETCONF responses from Junos. You encounter an element named <ok/> inside an <rpc-reply>. What does this indicate?

An automation script attempts to unlock a candidate configuration datastore that was previously locked by a different NETCONF session. Which RPC is required to force-terminate that session and release the lock?

What is the role of the <rpc> element in a NETCONF message exchange?

While executing a NETCONF edit-config operation, you want to ensure that any syntax errors or invalid statements immediately cause the device to roll back the entire transaction without applying partial changes. Which parameter achieves this?

An automation engineer is using the Junos XML API over NETCONF to load a configuration change into the candidate datastore. The engineer wants to ensure that the change is committed automatically only if the candidate configuration passes a validation check. Which NETCONF operation should the engineer use to validate the candidate configuration before committing?

A network automation engineer is using the Junos XML API over NETCONF to make configuration changes. The engineer wants to ensure that if the commit fails, the candidate configuration is automatically rolled back to its previous state without manual intervention. Which NETCONF operation should the engineer use to achieve this?

When using NETCONF to edit a Junos configuration, you include the attribute operation="create" on an existing configuration leaf. What behavior does the device exhibit?

An automation script executes a NETCONF <get-config> query with a specific subtree filter for interface statistics. However, the response contains configuration data instead of operational statistics. Why did this occur?

Which tool or library is commonly used in Python to simplify interacting with Junos NETCONF APIs by abstracting low-level XML handling?

Which NETCONF RPC tag is used to gracefully terminate an active NETCONF session with a Junos device?

Which XML tag encapsulates the entire response returned by a Junos device in reply to a valid NETCONF RPC request?

An engineer applies a configuration change using NETCONF with <edit-config> and specifies default-operation="replace" at the top level, but includes an element with operation="merge". How does Junos evaluate this?

You send an edit-config RPC with an invalid XML tag name. What is the standard structure of the error returned in the <rpc-reply>?

Which TWO statements are true regarding the NETCONF protocol hello message exchange? (Choose two.)

When establishing a NETCONF session over SSH, which standard capability announcement is exchanged during the initial hello message phase?

An automation engineer is writing a Python script that uses the ncclient library to connect to a Junos device via NETCONF. The engineer wants to retrieve the entire candidate configuration from the device. Which NETCONF operation should be used?
