Exhibit.
Referring to the exhibit, which statement about REST is correct?
Junos PyEZ tables are formatted using which file type?
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.
YAML uses which two data structures? (Choose two.)
YAML (YAML Ain't Markup Language) primarily uses two data structures:
Mappings: These are key-value pairs, similar to dictionaries or hashes in programming languages. In YAML, mappings are used to represent associative arrays or objects. They are defined with a colon (:) separating the key from the value.
Example:
key: value
name: John Doe
Sequences: These are ordered lists of items, equivalent to arrays or lists in other programming languages. Sequences in YAML are denoted by a dash (-) followed by a space and then the item.
Example:
fruits:
- Apple
- Banana
- Cherry
Detailed Explanation:
Mappings (B) allow you to define relationships between keys and values, making it possible to represent more complex data structures like dictionaries or objects.
Sequences (C) allow you to represent ordered collections, which is important for listing elements that must maintain a specific order.
YAML is often used in configuration files and data serialization in DevOps environments, such as in Ansible playbooks, Kubernetes manifest files, and CI/CD pipeline definitions. Its simplicity and human-readable format make it a popular choice for these applications.
YAML Official Documentation: YAML's specification outlines these core data structures.
Juniper Automation and DevOps Documentation: Provides best practices for using YAML in network automation scripts and configuration management.
Which two processes are used by Junos automation? (Choose two.)
In Junos OS, automation processes are integral to the system's ability to manage network operations efficiently. The following processes are used by Junos automation:
jsd (Junos XML API Server Daemon): This process is crucial for handling XML API requests, which are essential for automation tasks. The jsd process manages interactions between the Junos XML API and the Junos OS, enabling automation scripts to query and configure network devices using XML-formatted commands.
ifd (Interface Daemon): While ifd is primarily responsible for managing network interfaces, it is involved in automation through its role in the operational state of the network. Automation scripts often need to interact with network interfaces to retrieve status information or modify configurations, making ifd a critical component.
Other options like mod and kmd are not directly related to the primary automation processes in Junos OS. mod is related to chassis management, and kmd handles security services.
Juniper Networks Automation and DevOps Documentation: Provides detailed descriptions of processes like jsd and ifd and their roles in Junos OS.
Junos OS Daemons Documentation: Outlines the purpose and functionality of various daemons, including jsd and ifd.
