=: B. To reduce manual configuration errors and increase efficiency
b b b b b b b b b


Rationale: Network automation aims to reduce human error,
b b b b b b b b


increase consistency, and improve efficiency by automating
b b b b b b b


repetitive tasks such as VLAN configuration, user account
b b b b b b b b


management, and device provisioning .

C. Increased configuration errors b b


D. Slower deployment times b b




Answer: B. Version-controlled, repeatable network configurations
b b b b b


Rationale: Infrastructure as Code allows network configurations to be
b b b b b b b b b


defined in code, version-controlled, and applied consistently across
b b b b b b b b


devices, enabling repeatable and auditable deployments .
b b b b b b b




3. A network administrator wants to automate the configuration of 50
b b b b b b b b b


new switches across multiple school sites. Which approach is most
b b b b b b b b b b


efficient?
b


A. Configure each switch manually using CLI b b b b b

,B. Use a configuration management tool with templated configurations
b b b b b b b


C. Hire additional staff to configure switches
b b b b b


D. Leave switches with default configuration
b b b b




Answer: B. Use a configuration management tool with
b b b b b b b


templated configurations
b b


Rationale: Configuration management tools (e.g., Ansible, Puppet)
b b b b b b


allow administrators to define templates and apply configurations
b b b b b b b b


consistently across multiple devices simultaneously .
b b b b b b




4. In the context of network automation, what does "idempotency" mean?
b b b b b b b b b


A. The ability to run a configuration multiple times with the same result
b b b b b b b b b b b


B. The ability to change configurations randomly
b b b b b


C. The inability to revert changes
b b b b


D. The requirement to run configurations only once
b b b b b b




Answer: A. The ability to run a configuration multiple times with the same
b b b b b b b b b b b b


result
b


Rationale: Idempotency ensures that running an automation script multiple
b b b b b b b b


times produces the same outcome, preventing unintended changes on
b b b b b b b b b


subsequent runs .
b b b




5. Which of the following is a common network automation tool used
b b b b b b b b b b


for configuration management?
b b b


A. Microsoft Word b


B. Ansible
C. Adobe Photoshop b


D. Excel
Answer: B. Ansible b b


Rationale: Ansible is a popular open-source automation tool used for
b b b b b b b b b


configuration management, application deployment, and task automation,
b b b b b b b


including network device configuration .
b b b b b




6. A school district network uses SNMP for monitoring. What is the
b b b b b b b b b b


primary function of SNMP?
b b b b


A. Device configuration b


B. Network monitoring and management b b b

,C. User authentication b


D. File transfer b




Answer: B. Network monitoring and management
b b b b b


Rationale: Simple Network Management Protocol (SNMP) is used for
b b b b b b b b


collecting information about network devices, monitoring performance,
b b b b b b b


and receiving alerts about network conditions .
b b b b b b b




7. Which Python library is commonly used for network automation
b b b b b b b b


to establish SSH connections to network devices?
b b b b b b b


A. Pandas
B. NumPy
C. Netmiko
D. Matplotlib
Answer: C. Netmiko b b


Rationale: Netmiko is a Python library that simplifies SSH connections
b b b b b b b b b


to network devices and provides consistent methods for sending
b b b b b b b b b


commands and receiving output .
b b b b b




8. What is the purpose of using version control (e.g., Git) in
b b b b b b b b b b


network automation?
b b


A. To store binary files
b b b


B. To track changes, collaborate, and revert to previous configurations
b b b b b b b b


C. To compile Python scripts
b b b


D. To monitor network performance
b b b




Answer: B. To track changes, collaborate, and revert to previous
b b b b b b b b b


configurations
b


Rationale: Version control systems like Git allow teams to track changes,
b b b b b b b b b b


collaborate on code, maintain history, and revert to previous versions when
b b b b b b b b b b b


needed .
b b




9. In a school district network, VLANs are used to:
b b b b b b b b


A. Increase network speed b b


B. Segment network traffic for security and organizational purposes
b b b b b b b


C. Replace physical cabling b b


D. Provide internet access b b

, Answer: B. Segment network traffic for security and organizational purposes
b b b b b b b b b


Rationale: VLANs (Virtual Local Area Networks) segment network traffic,
b b b b b b b b b


isolating different groups (e.g., students, staff, guests) for security and
b b b b b b b b b b


performance .
