Question 201

Which Cisco platform provides centralized management and automation capabilities for enterprise networks?

1. Cisco DNA Center
2. Cisco AnyConnect
3. Cisco Secure Client
4. Cisco Packet Tracer

Correct Answer: 1

Explanation

Cisco DNA Center is a centralized network management and automation platform designed for enterprise networks. It provides capabilities for device management, network provisioning, assurance, policy, and automation through a centralized interface and APIs. Automation applications can interact with Cisco DNA Center programmatically to retrieve information or perform supported operations. Cisco AnyConnect and Cisco Secure Client are primarily associated with endpoint connectivity and security, while Packet Tracer is a network simulation and learning tool. Therefore, Cisco DNA Center is the appropriate platform for centralized enterprise network management and automation.

Question 202

Which Cisco DNA Center capability provides information about network health and device performance?

1. Discovery
2. Assurance
3. Software packaging
4. CLI parsing

Correct Answer: 2

Explanation

Cisco DNA Center Assurance provides visibility into network health, device performance, client experience, and other operational information. It helps administrators identify potential problems and understand the state of the network using collected telemetry and analytics. Discovery is used to identify and add network devices, while other capabilities support provisioning, policy, and software management. Assurance is particularly relevant to automation because operational data can be used to identify conditions that may require remediation or further investigation. Therefore, Assurance is the correct capability for network health and performance visibility.

Question 203

Which API style commonly uses resources identified by URLs and standard HTTP methods?

1. REST
2. SMTP
3. SNMP
4. FTP

Correct Answer: 1

Explanation

REST is an architectural style commonly used to design web APIs around resources identified through URLs or URI paths. Standard HTTP methods such as GET, POST, PUT, PATCH, and DELETE are commonly used to interact with those resources. REST APIs are widely used in network automation because software can programmatically retrieve information and make supported configuration changes. SMTP is primarily used for email, SNMP is used for network management and monitoring, and FTP is designed for file transfer. Therefore, REST is the API style described.

Question 204

Which HTTP method is generally considered safe because it is intended to retrieve information without modifying the resource?

1. POST
2. DELETE
3. GET
4. PATCH

Correct Answer: 3

Explanation

The HTTP GET method is generally considered a safe method because its intended purpose is to retrieve a representation of a resource without requesting a state-changing operation. Network automation applications commonly use GET requests to retrieve device inventory, interface information, operational statistics, or configuration data from REST APIs. POST, PATCH, and DELETE are generally associated with operations that can modify server-side state. While API implementations can behave differently, standard REST conventions treat GET as a retrieval operation. Therefore, GET is the correct answer.

Question 205

Which HTTP status code indicates that a request was successfully processed but the server has no content to return?

1. 204
2. 401
3. 404
4. 500

Correct Answer: 1

Explanation

HTTP status code 204 means “No Content.” It indicates that the server successfully processed the request but does not have a response body to return. Automation scripts may encounter a 204 response after an operation that successfully changes or removes a resource when the API does not need to return additional information. Status 401 relates to authentication, 404 indicates that a resource was not found, and 500 indicates an internal server error. Therefore, 204 is the correct status code for a successful request with no response content.

Question 206

Which Python expression retrieves the value associated with the key hostname from a dictionary named device?

1. device.hostname
2. device[“hostname”]
3. device(hostname)
4. device->hostname

Correct Answer: 2

Explanation

Python dictionaries use keys to access associated values. The expression device[“hostname”] retrieves the value stored under the hostname key in the dictionary named device. This syntax is common when processing JSON API responses because JSON objects are commonly converted into Python dictionaries. Dot notation such as device.hostname is not the standard way to access dictionary keys. The other two forms are also not valid Python dictionary access syntax. Therefore, device[“hostname”] is the correct expression.

Question 207

Which Python method can be used to add an item to the end of a list?

1. insert_end()
2. append()
3. add_item()
4. push()

Correct Answer: 2

Explanation

The Python append() method adds a single item to the end of a list. This is useful in automation scripts when dynamically building collections of devices, IP addresses, interfaces, or API results. For example, a script can start with an empty list and append device names as they are discovered. Python does not use push() as the standard list method, and insert_end() and add_item() are not standard list methods. Therefore, append() is the correct method for adding an item to the end of a Python list.

Question 208

Which Python operation can extract a portion of a list using start and end positions?

1. Slicing
2. Casting
3. Importing
4. Hashing

Correct Answer: 1

Explanation

Python slicing allows a program to extract a portion of a sequence such as a list or string. A slice is commonly written using syntax such as items[start:end], where the start position is included and the end position is normally excluded. Slicing can be useful when an automation script needs to process only a subset of devices, API results, or configuration lines. Casting changes a value from one data type to another, importing loads modules, and hashing generates hash values. Therefore, slicing is the correct operation.

Question 209

What does a Python list comprehension provide?

1. A concise way to create a list from an iterable
2. A method for connecting through SSH
3. A mechanism for encrypting passwords
4. A replacement for JSON

Correct Answer: 1

Explanation

A Python list comprehension provides a concise syntax for creating a new list from an iterable, optionally applying an expression or condition to each item. For example, an automation script could create a list of device hostnames from a collection of device objects. List comprehensions can make simple data transformations more compact and readable when used appropriately. They do not provide SSH connectivity, password encryption, or replace JSON. Network automation scripts often use list comprehensions when processing API responses or transforming structured data. Therefore, creating a list from an iterable is the correct answer.

Question 210

Which Python function can be used to determine the number of items in a list?

1. countall()
2. size()
3. len()
4. total()

Correct Answer: 3

Explanation

The Python built-in len() function returns the number of items in a collection such as a list, tuple, dictionary, or set. In network automation, it can be used to determine how many devices were discovered, how many interfaces are present in a data structure, or how many API results were returned. Other functions such as size() and total() are not the standard Python built-ins for this purpose. Therefore, len() is the correct function for determining the number of items in a collection.

Question 211

Which Python file mode opens an existing file for reading?

1. w
2. a
3. r
4. x

Correct Answer: 3

Explanation

The Python file mode r opens a file for reading. This is useful when automation scripts need to load information from configuration files, inventories, templates, or other text-based sources. The w mode opens a file for writing and can overwrite existing content, while a opens a file for appending data. The x mode is used to create a new file and can fail if the file already exists. Therefore, r is the correct mode when the goal is to read an existing file.

Question 212

Which Python statement is commonly used to safely open a file and automatically close it after processing?

1. with open(…)
2. file.start(…)
3. open.safe(…)
4. using file(…)

Correct Answer: 1

Explanation

The Python with open(…) statement is commonly used for file operations because it manages the file context and ensures that the file is properly closed after the associated block finishes. This is especially useful in automation scripts that frequently read templates, inventories, logs, or configuration data. Proper resource handling helps prevent problems associated with leaving files open unnecessarily. The other listed forms are not standard Python syntax for safely managing file resources. Therefore, with open(…) is the correct approach for this purpose.

Question 213

Which Python module is commonly used to work with regular expressions?

1. re
2. regexlib
3. pattern
4. matchtext

Correct Answer: 1

Explanation

The Python re module provides support for regular expressions. Regular expressions can be useful in automation when searching, matching, or extracting patterns from text such as device output, log messages, configuration files, or command results. For example, a script could use a regular expression to identify IPv4 addresses or specific lines in CLI output. Although third-party libraries can also provide pattern-matching functionality, Python’s standard library includes the re module. Therefore, re is the correct module for regular-expression operations.

Question 214

Which Git command downloads a remote repository and creates a local working copy?

1. git merge
2. git clone
3. git branch
4. git diff

Correct Answer: 2

Explanation

The git clone command creates a local copy of an existing remote Git repository. It downloads the repository’s content and metadata so that a developer can work with the project locally. This is commonly the first step when joining an existing automation project stored on a remote Git server. git merge combines branch changes, git branch manages branches, and git diff displays differences between versions or working states. Therefore, git clone is the correct command for creating a local working copy of a remote repository.

Question 215

Which Git command displays changes between different versions or states of files?

1. git diff
2. git push
3. git init
4. git remote

Correct Answer: 1

Explanation

The git diff command displays differences between versions, commits, the working tree, or other Git states depending on how it is used. It is useful during automation development because engineers can review changes to Python scripts, Ansible playbooks, templates, or configuration files before committing them. git push sends local commits to a remote repository, git init initializes a repository, and git remote manages remote repository information. Therefore, git diff is the correct command for reviewing differences.

Question 216

What is the primary purpose of a pull request in a collaborative software project?

1. To request review and integration of proposed changes
2. To automatically replace the operating system
3. To assign an IP address to a router
4. To encrypt a Git repository

Correct Answer: 1

Explanation

A pull request is commonly used to propose changes for review before they are integrated into another branch. In automation projects, developers can use pull requests to have Python scripts, Ansible playbooks, templates, or infrastructure code reviewed by other team members. Reviewers can comment on the changes and automated checks can run before the changes are merged. A pull request does not assign IP addresses, replace an operating system, or automatically encrypt a repository. Therefore, requesting review and integration of proposed changes is its primary purpose.

Question 217

Which software-development practice automatically checks code changes whenever they are submitted to a shared repository?

1. Continuous Integration
2. Manual configuration
3. Packet forwarding
4. Static routing

Correct Answer: 1

Explanation

Continuous Integration, or CI, is a software-development practice in which code changes are frequently integrated and automatically validated through processes such as builds and tests. In network automation projects, CI can run Python tests, linting, configuration validation, or other checks whenever changes are submitted. This helps identify problems earlier in the development lifecycle. Manual configuration, packet forwarding, and static routing are unrelated to software-development integration practices. Therefore, Continuous Integration is the correct answer.

Question 218

Which type of test generally focuses on a small, isolated piece of application logic?

1. Unit test
2. System outage test
3. Packet capture
4. Acceptance-only test

Correct Answer: 1

Explanation

A unit test generally focuses on a small, isolated piece of application logic, such as a function or method. In a network automation project, a unit test could verify that a Python function correctly validates an IP address, transforms API data, or generates a specific value. Unit tests are usually designed to execute quickly and identify errors in individual components. Larger tests may evaluate interactions between multiple components or complete workflows. Packet captures and system outage testing serve different purposes. Therefore, a unit test is the appropriate type of test for isolated application logic.

Question 219

Which automation approach uses commands or procedures that explicitly describe how to reach a desired configuration?

1. Declarative
2. Imperative
3. Passive
4. Event-only

Correct Answer: 2

Explanation

Imperative automation specifies the actions or procedures that should be performed to accomplish a task. The automation logic focuses on the steps required to produce a result, such as executing commands in a particular sequence. Declarative automation instead describes the desired final state and allows the automation system to determine the necessary changes. Both approaches can be useful depending on the technology and workflow. Therefore, when automation explicitly describes the commands or procedures required to reach a configuration, it is considered imperative.

Question 220

Which component is commonly used as a centralized source for storing information about devices, addresses, and network assets?

1. Source-of-truth system
2. Packet sniffer
3. Terminal emulator
4. Web browser cache

Correct Answer: 1

Explanation

A source-of-truth system provides a centralized and authoritative location for structured information used by automation and network operations. It may contain details such as device names, management addresses, interfaces, VLANs, locations, or other infrastructure attributes. Automation systems can retrieve this information rather than relying on manually maintained spreadsheets or disconnected data sources. Keeping infrastructure information centralized can improve consistency and make automation workflows more predictable. A packet sniffer captures traffic, a terminal emulator provides command-line access, and a browser cache stores web resources. Therefore, a source-of-truth system is correct.
