- Topic 4: Application Deployment and Security: In this section, the advantages of edge computing are defined in addition to identifying attributes of different application deployment frameworks. It also covers how to identify the attributes of these application deployment types, virtual machines, bare metal, and containers. More topics covered include how to describe elements for a CI/CD pipeline in application deployments, construct a Python unit test, interpret contents of a Dockerfile, use Docker images in a local developer environment, and to identify application security issues related to secret protection, encryption (storage and transport), and data handling.
- Topic 5: Infrastructure and Automation: The topics covered include how to describe the value of model-driven programmability for infrastructure automation, compare controller-level to device-level management, describe the use and roles of network simulation and test tools, explain the components and benefits of CI/CD pipeline in infrastructure automation, define foundations of infrastructure as code, the skills related to automation tools such as Ansible, Terraform, and Cisco NSO, identify the workflow being automated by a Python script. Moreover, the topics include how to pinpoint the workflow being automated by an Ansible playbook, pinpoint the workflow being automated by a bash script, interpret the outcomes of a RESTCONF or NETCONF query, YANG models, and a unified diff.
- Topic 6: Networking Fundamentals: The topics covered include how to explain the purpose and usage of MAC addresses and VLANs, the purpose and usage of IP addresses, routes, subnet mask/prefixes, and gateways. It also covers topics such as explaining the function of switches, routers, firewalls, and load balancers and analyzes a basic network topology diagram with switches, routers, firewalls, load balancers, and port values. The topics also include the function of management, data, and control planes in a network device, the functionality of these IP Services: DHCP, DNS, NAT, SNMP, NTP, recognize common protocol port values including SSH, Telnet, HTTP, HTTPS, and NETCONF, and how to pinpoint the cause of application connectivity problems related to NAT, proxy, and VPN.

What are the two purposes for using a VLAN in a network? (Choose two)
VLANs (Virtual Local Area Networks) serve several purposes in a network. Two primary purposes are:
Segmentation of the Network: VLANs logically segment a network into different broadcast domains, which helps in managing and controlling broadcast traffic. This segmentation helps improve performance and security by isolating certain types of traffic from others.
Creating Broadcast Domains: Each VLAN is a separate broadcast domain. By using VLANs, a network administrator can reduce the size of broadcast domains, thereby reducing broadcast traffic and increasing the efficiency of the network.
These purposes are in line with Cisco's network design principles and best practices for using VLANs. Reference: Cisco DevNet Associate Certification Guide, Chapter on VLANs and their uses.
Refer to the exhibit.
Fill in the blanks to complete the cURL command to the list of networks in the Meraki organization with an id of 384279060
Solution below
To list the networks in a Meraki organization using the Meraki API, you need to construct a proper cURL command. The command must include the URL endpoint specific to the Meraki organization ID and the required API key for authentication. The correct cURL command to list networks in the organization with ID 384279060 is:
curl -X GET -L \
--url https://api.meraki.com/api/v0/organizations/384279060/networks \
-H 'X-Cisco-Meraki-API-Key: $meraki_api_key'
Here:
-X GET: Specifies the request method as GET.
-L: Follows any redirects.
--url: Specifies the API endpoint URL.
-H 'X-Cisco-Meraki-API-Key: $meraki_api_key': Adds the API key header for authentication.
Refer to the exhibit.
A developer just finished testing a Python script and wants to save the list of packages and versions installed on the current machine. The developer must make sure that it will not cause any issues if tested on another device due to different library versions. Which line of code needs to be placed on the snippet where the code is missing?
The pip freeze command is used to output installed packages in the current environment and their versions. The > operator redirects this output to a file, in this case, requirements.txt.
pip freeze: Outputs the list of installed packages and their versions.
Redirection: The > operator is used to redirect the output to a file.
Option B is correct as it uses the > operator to redirect the output of pip freeze to requirements.txt.
What should a CI/CD pipeline aim to achieve?
A CI/CD (Continuous Integration/Continuous Deployment) pipeline aims to automate the process of integrating code changes, testing them, and deploying them to production with minimal manual intervention. This automation improves efficiency, reduces errors, and ensures consistency across deployments. The key goal is to streamline and expedite the software development lifecycle by allowing developers to focus more on coding and less on the deployment process. Manual interaction is minimized to maintain the flow and reliability of the pipeline. Reference: Cisco DevNet Associate Certification Guide, Chapter 5, Section on CI/CD Pipelines.
Refer to the exhibit.
A developer is part of a team that is working on an open-source project in which source code is hosted in a public GitHub repository. While the application was built, security concerns were addressed by encrypting the credentials on the server. After a few months, the developer realized that a hacker managed to gain access to the account. The exhibit contains part of the source code for the login process. Why was the attacker able to access the developer's account?
The exhibit shows that the credentials are base64 encoded and included in the source code. Base64 encoding is not a secure method of protecting credentials as it can be easily decoded. Therefore, an attacker who gains access to the source code can decode the credentials and gain unauthorized access to the account. Proper security practices should involve storing credentials securely, such as using environment variables or secure vaults, and not hardcoding them in the source code.
