Which two statements about XML schema definition (XSD) files are correct? (Choose two.)
- A. Every XML document must have an XSD file defined for it.
- B. An XSD file is not an XML document.
- C. XSD files ensure that everyone working with the XML document uses a common set of tags.
- D. XSD files define all the elements in an XML document and the document XML hierarchy.
正解：C、D
解説：
XML Schema Definition (XSD) files are used to define the structure and data types of an XML document.
They ensure that the XML document adheres to a specific structure by defining the allowed elements, attributes, and their data types, thereby enforcing a consistent format.
* Option Ais correct because XSD files define the elements, attributes, and structure (hierarchy) of an XML document.
* Option Dis correct because XSD files provide a standardized format, ensuring that all parties working with the XML document use the same set of tags and structure.
* Option B (Every XML document must have an XSD file defined for it)is incorrect; not every XML document requires an XSD file, although it's beneficial for validation.
* Option C (An XSD file is not an XML document)is incorrect because XSD files themselves are written in XML.
Supporting References:
* W3C XML Schema Definition (XSD) Documentation:Explains the purpose and structure of XSD files, including their role in defining XML document schemas.
質問 # 39
Which two programming languages are used for Junos on-box scripting? (Choose two.)
- A. XSLT
- B. Ruby
- C. Perl
- D. SLAX
正解：A、D
解説：
Junos on-box scripting supports the following programming languages:
SLAX (C): SLAX (Structured Language for XML) is a scripting language designed specifically for Junos devices. It allows for easy manipulation of XML data, making it ideal for creating Junos scripts that interact with device configurations.
XSLT (D): XSLT (Extensible Stylesheet Language Transformations) is another language used for transforming XML documents into other formats. It is commonly used in Junos for transforming XML data into different views or outputs.
Options A (Perl) and B (Ruby) are not used for Junos on-box scripting. While these languages are popular in other contexts, Junos scripting relies heavily on XML-based languages like SLAX and XSLT.
Reference:
Junos XML API and Scripting Guide: Describes the use of SLAX and XSLT for on-box scripting.
Juniper Networks Automation Documentation: Provides examples and best practices for using SLAX and XSLT in Junos scripting.
質問 # 40
Which two statements about Junos automation are correct? (Choose two.)
- A. The Junos REST API client is off-box.
- B. Junos automation allows for device provisioning through the console port.
- C. Junos automation does not allow for device provisioning throuqh the console port.
- D. The Junos REST API client is on-box.
正解：B、D
質問 # 41
Which two statements are valid regarding Junos automation? (Choose two.)
- A. The jsd process handles XML API calls.
- B. The mod process handles XML API calls.
- C. The jsd process handles JET API requests.
- D. The mgd process handles JET API requests.
正解：A、C
解説：
In Junos automation, several processes handle API requests, and understanding which process handles what is crucial:
jsd Process:
XML API Calls (A): The jsd process is responsible for handling XML API calls, which are a significant part of Junos automation. XML API allows for structured and standardized communication with Junos devices, enabling automation scripts to query and configure devices.
JET API Requests (C): The jsd process also handles JET (Junos Extension Toolkit) API requests. JET provides a more modern, programmable interface for interacting with Junos OS, and jsd is the process that manages these interactions.
mgd Process (Incorrect Option):
Not for JET API Requests: The mgd process handles general management operations, such as CLI commands and managing the configuration database, but it does not handle JET API requests. That role is fulfilled by jsd.
mod Process (Incorrect Option):
Not for XML API Calls: The mod process deals with managing chassis components and is not involved in handling XML API calls.
Reference:
Juniper Networks JET and XML API Documentation: Describes the roles of jsd in handling both XML and JET API requests.
Junos Automation and DevOps Documentation: Provides insights into how different processes interact with Junos APIs.
質問 # 42
What are two Junos PyEZ configuration object methods? (Choose two.)
- A. commie ()
- B. config ()
- C. lockO
- D. device ()
正解：B、C
解説：
In Junos PyEZ, the Config object provides various methods for interacting with device configurations. Two of the key methods are:
lock(): This method locks the candidate configuration database to prevent other users or processes from making changes while you are modifying the configuration.
config(): This method is used to create a Config object that represents the configuration database, allowing you to load, modify, and commit configuration changes.
Option C (lock) and Option D (config) are correct because they are valid methods provided by the PyEZ Config object.
Option A (commie) and Option B (device) are incorrect as they are not methods of the Config object.
Supporting Reference:
Junos PyEZ Documentation: Details the methods available in the Config object, including lock() and config().
質問 # 43
Junos PyEZ is a microframework used to operate the Junos OS using which language?
- A. Puppet
- B. Ruby
- C. Python
- D. Chef
正解：C
解説：

20OS).
質問 # 44
Which process is responsible for JET automation requests?
- A. rpd
- B. jsrpd
- C. jsd
- D. mgd
正解：C
解説：
Thejsd(Junos Script Daemon) process is responsible for handlingJET (Junos Extension Toolkit)automation requests. The JET framework allows for more programmable interactions with Junos devices, using APIs to manage and automate network functions. The jsd process handles these API requests, executes the relevant scripts, and interacts with the Junos configuration and operational states accordingly.
JET enables developers to write applications that interact with the Junos OS through APIs, providing a powerful tool for network automation, monitoring, and configuration management. The jsd process ensures that all JET-related operations are processed and executed properly.
Why the Other Options Are Incorrect:
* A. jsrpd:This is not a process associated with JET automation requests.
* B. mgd:The mgd process is responsible for handling management tasks like CLI commands and configuration changes but is not directly responsible for JET automation requests.
* C. rpd:The rpd (Routing Protocol Daemon) manages routing protocols like BGP and OSPF but has no involvement in JET automation.
References from Juniper Documentation:
* Juniper's documentation on JET and the jsd process outlines how this daemon manages script and API request processing for automation tasks.

- C. The Juniper device rejects the connection
- D. The Juniper device took too long to reply to the RPC call
正解：D
質問 # 48
What are two important aspects of the DevOps culture? (Choose two.)
- A. people
- B. use of specific tools
- C. separation of duties
- D. communication
正解：A、D
解説：
Two important aspects of the DevOps culture are:
* Communication (A): In a DevOps environment, continuous and effective communication between development, operations, and other stakeholders is crucial. It ensures that everyone is aligned, reduces misunderstandings, and facilitates faster and more efficient workflows.
* People (D): DevOps is as much about the people as it is about the processes and tools. The culture emphasizes collaboration, shared responsibility, and a mindset focused on continuous improvement.
Empowering people to work together across different disciplines is at the heart of DevOps.
Options B and C are not primary aspects of the DevOps culture. While tools are essential in implementing DevOps practices, the culture emphasizes communication and collaboration among people more than the use of specific tools or rigid separation of duties.
* DevOps Handbook: Discusses the cultural aspects of DevOps, with a focus on communication and people.
* DevOps Best Practices: Highlights the importance of fostering a culture that prioritizes collaboration and shared goals.

質問 # 50
Junos PyEZ tables are formatted using which file type?
- A. txt
- B. IXML
- C. SON
- D. YAML
正解：D
解説：
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.
