NEW QUESTION # 32
Which Junos API supports direct modification of the Ephemeral database?
Answer: C
Explanation:
In Junos, the JET (Junos Extension Toolkit) API supports direct modification of the Ephemeral database. The Ephemeral database is a temporary configuration database used in Junos OS, allowing for changes that do not persist after a reboot unless explicitly committed to the permanent configuration.
JET API: Allows for high-performance interactions with Junos, including the ability to make changes to the Ephemeral database, which is useful for temporary configurations, dynamic policies, and other operational tasks.
Other options like WebSocket, SOAP, and REST do not provide direct access to the Ephemeral database in Junos.
Reference:
Juniper Networks JET Documentation: Details how JET API interacts with the Ephemeral database.
Junos Automation and DevOps Documentation: Discusses the use of JET for automation and dynamic configuration.
NEW QUESTION # 33
Which statement about the NETCONF content layer is true?
Answer: D
Explanation:
The NETCONF protocol, used for network management, utilizes XML for encoding the RPC (Remote Procedure Call) requests and responses. XML is chosen because of its flexibility and ability to represent hierarchical data structures, making it well-suited for representing network configurations and states.
Option B is correct because XML is the standard format used for NETCONF RPC payloads.
Options A (YAML), C (JSON), and D (HTML) are incorrect because these formats are not used by NETCONF for its RPC payloads.
Supporting Reference:
RFC 6241 - NETCONF Protocol: This RFC describes the use of XML for encoding NETCONF messages.
NEW QUESTION # 34
Which two standard logical operators does XPath support? (Choose two.)
Answer: B,C
Explanation:
XPath is a query language used for selecting nodes from an XML document. It supports various logical operators that can be used to create complex queries. The two standard logical operators supported by XPath are:
NOT: This operator negates a condition, returning true if the condition is false, and vice versa.
AND: This operator is used to combine two conditions, and it returns true only if both conditions are true.
Option A (IOR) and Option D (MAMD) are not standard XPath operators.
Supporting Reference:
XPath Documentation: The W3C XPath specification lists the standard operators supported in XPath, including AND and NOT.
NEW QUESTION # 35
Junos PyEZ tables are formatted using which file type?
Answer: B
Explanation:
Junos PyEZ uses YAML (YAML Ain't Markup Language) files to define the format for tables and views when working with operational and configuration data. YAML is a human-readable data format that is commonly used for configuration files, making it suitable for defining data structures in PyEZ.
Option B (YAML) is correct because PyEZ tables are defined using YAML files.
Options A (JSON), C (txt), and D (IXML) are incorrect in this context, as YAML is the standard format used.
Supporting Reference:
Junos PyEZ Tables Documentation: Explains the use of YAML files for formatting tables and views in Junos PyEZ.
NEW QUESTION # 36
Which Junos configuration database is updated by PyEZ by default?
Answer: D
Explanation:
An event script is used to automate responses to system events in Junos, such as an interface going down. These scripts are triggered automatically when a specified event occurs, making them suitable for tasks like monitoring interface status and executing actions when the status changes.
Option B (event) is correct because event scripts are designed for reacting to system events like an interface going down.
Option A (commit) is used for configuration changes, Option C (operation) is used for operational tasks, and Option D (SNMP) is not applicable in this context.
Supporting Reference:
Juniper Networks Event Scripts Documentation: Details how event scripts are used to automate responses to specific system events in Junos
