You must use Junos PyEZ to configure unique IP addresses on individual machines.
Which two features willpermit this requirement? (Choose). Ian SCP module
- A. a BSON data file
- B. a Jinja2 template
- C. a YAML data file
- D. an SCP module
Answer: B,C
Explanation:
To configure unique IP addresses on individual machines using Junos PyEZ, you can use the following features:
* YAML Data File (C): YAML files are used to store configuration data in a human-readable format.
They are often used in combination with Jinja2 templates to provide the data necessary for template rendering.
* Jinja2 Template (D): Jinja2 is a templating engine for Python that allows you to create dynamic templates. When used with Junos PyEZ, a Jinja2 template can be filled with data (such as IP addresses from a YAML file) to generate configuration snippets that are applied to different devices.
Options A (SCP module) and B (BSON data file)are not typically used with Junos PyEZ for this purpose.
* Junos PyEZ Documentation: Discusses the use of YAML files and Jinja2 templates for generating configurations.
* Jinja2 Templating Documentation: Provides details on how to create and use templates in Python scripts.

NEW QUESTION # 32
You want to use a Python package or module.
In this scenario, which statement would accomplish this task?
- A. Import
- B. dir
- C. input
- D. reap
Answer: A
Explanation:
In Python, to use a package or module, you use theimportstatement. This statement allows you to load a module into your script so that you can use its functions, classes, and variables. For example, if you wanted to use themathmodule, you would writeimport math. This makes all the functions and constants in themathmodule available for use in your program.
* Option A (reap), B (dir), and C (input)do not serve the purpose of importing modules.diris used to list the attributes of an object,inputis used to get user input, andreapis not a valid Python command related to importing modules.
Supporting References:
* Python Documentation on Imports:The Python documentation provides clear guidelines on how to use theimportstatement to include modules in your Python scripts.
NEW QUESTION # 33
Which two statements are correct about a Python dictionary data type? (Choose two.)
- A. The data stored in a dictionary data type is sequenced and indexed.
- B. The data contained in a dictionary data type is a key/value pair.
- C. The data stored in a dictionary data type is not sequenced or indexed.
- D. The data contained in a dictionary data type cannot be removed once the dictionary has been created.
Answer: B,C
Explanation:
A Python dictionary is a data type that stores data in the form of key/value pairs. It has the following characteristics:
* Key/Value Pair (C): Each entry in a dictionary is a pair consisting of a unique key and a value. The key is used to access the corresponding value.
* Not Sequenced or Indexed (D): Unlike lists or tuples, dictionaries do not maintain order for their entries (in versions prior to Python 3.7). Even though Python 3.7+ maintains insertion order, dictionaries are not considered indexed or sequenced in the traditional sense like lists, where elements are accessed via positional index.
Option A is incorrectbecause dictionary entries can be added, modified, or removed after the dictionary is created.Option B is incorrectbecause dictionaries are not accessed by a numeric index but rather by their keys.
* Python Official Documentation: Details the nature of dictionaries, including their mutability and key
/value structure.
* Python Data Structures Guide: Explains dictionary operations and characteristics.

NEW QUESTION # 34
Which API does the Junos CLI use to modify the configuration database?
- A. XML API
- B. REST API
- C. JET API
- D. RPC API
Answer: B
NEW QUESTION # 35
Which two statements about the REST API are correct? (Choose two.)
- A. The TCP session state is maintained by the server.
- B. The TCP session state is maintained by the client
- C. The REST API application is stateful.
- D. The REST API application is stateless.
Answer: B,D
Explanation:
REST (Representational State Transfer) is an architectural style for designing networked applications, and its key principles include:
* Statelessness (B): Each request from the client to the server must contain all the information needed to understand and process the request. The server does not store any session state between requests, meaning each request is independent and does not rely on previous ones.
* TCP Session State (C): While REST itself is stateless, the underlying TCP connection's state, such as keeping the connection alive or managing retries, is handled by the client. The server does not retain information about the TCP connection beyond the processing of the individual request.
Options A and D are incorrect because they imply that the REST API is stateful, which contradicts the stateless nature of REST.
* REST API Design Principles: Describes the stateless nature of REST and the responsibility of clients in managing session state.
* Web Development Documentation: Discusses how REST APIs operate, focusing on statelessness and client-server interaction.

device - Device(host-host, user-"lab", passwd-"lab123")... - C. while True:
device - Device(host-"vmx-1", user-"lab", passwd-"lab123")... - D. with Device(host="vmx-1", user="lab", passwd="lab123") as device:...
Answer: D
Explanation:
The "open" builtin function Python was implemented to support the Context Manager protocol (called using "with").
NEW QUESTION # 39
Which Junos API supports direct modification of the Ephemeral database?
- A. SOAP
- B. WebSocket
- C. REST
- D. JET
Answer: D
Explanation:
In Junos, theJET (Junos Extension Toolkit)API supports direct modification of theEphemeral 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.
* 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 # 47
Which two statements are true about an XML schema document? (Choose two.)
- A. lit is formatted as an XSD file.
- B. It is formatted as an XLT file.
- C. It cannot be examined in the Junos CLI.
- D. It is an authoritative source for operational and configuration XML.
Answer: A,D
Explanation:
An XML schema document (XSD) is a key component in defining the structure and constraints of XML data used in various applications, including Junos:
* Authoritative Source (C): An XML schema document serves as the authoritative definition of the structure, content, and semantics of XML documents. It ensures that the XML data adheres to specific rules and formats, which is essential for both operational and configuration XML.
* XSD Format (D): XML schema documents are typically written in the XSD (XML Schema Definition) format, which provides a formal description of the XML document's structure.
Option A is incorrectbecause XML schemas are not formatted as XLT files (which are related to XSLT transformations), andOption B is incorrectbecause XML schemas can indeed be examined in the Junos CLI using appropriate commands.
* W3C XML Schema Definition Language (XSD) Documentation: Provides comprehensive information on the XSD format.
* Juniper Networks Documentation: Discusses the role of XML schemas in managing Junos configurations.

Which type of on-box script should you use to accomplish this task?
- A. event
- B. SNMP
- C. operation
- D. commit
Answer: A
Explanation:
Aneventscript 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, andOption D (SNMP)is not applicable in this context.
