NEW QUESTION # 184
What is a characteristic of Waterfall compared to Agile software development method?
- A. Waterfall focuses on continuous improvement, and Agile focuses on the design phase.
- B. Waterfall specifies requirements before development begins, and Agile responds flexibly to changes in requirements.
- C. Waterfall separates the project development lifecycle into sprints, and Agile does not use cycles.
- D. Waterfall uses reviews with step by step approach, and Agile uses a serially phased approach.
Answer: B
Explanation:
The Waterfall model is a linear and sequential approach to software development. In Waterfall, all requirements are specified at the beginning of the project, and each phase (e.g., design, implementation, testing) must be completed before moving on to the next. This makes it less adaptable to changes once the project is underway.
Agile, on the other hand, is an iterative approach that allows for flexible responses to changes in requirements.
Agile development is organized into small, incremental cycles called sprints, which typically last 1-4 weeks.
During each sprint, a small portion of the project is developed, and changes can be incorporated based on feedback and evolving requirements.

NEW QUESTION # 186
An engineer needs to retrieve a list of locally available Firepower Threat Defense upgrade packages by using the Firepower Management Center REST API. The engineer uses a GET request with the URL:
/api/fmc_platform/v1/updates/upgradepackages/f413afeb-e6f6-75f4-9169-6d9bd49s625e What does "f413afeb-e6f6-75f4-9169-6d9bd49s625e" represent?
- A. container UUID
- B. object UUID
- C. domain UUID
- D. package UUID
Answer: D
Explanation:
In the context of the Firepower Management Center (FMC) REST API, the string
"f413afeb-e6f6-75f4-9169-6d9bd49s625e" represents the unique identifier (UUID) for a specific upgrade package. This UUID is used to uniquely identify and reference the upgrade package when performing operations through the API.
Reference: Cisco DevNet Associate documentation on Firepower Management Center REST API and UUID usage.
NEW QUESTION # 187
A local Docker alpine image has been created with an image ID of a391665405fe and tagged as "latest".
Which command creates a running container based on the tagged image, with the container port 8080 bound to port 80 on the host?
- A. docker run -p 8080:80 alpine:latest
- B. docker exec -p 8080:80 alpine:latest
- C. docker start -p 8080:80 alpine:latest
- D. docker build -p 8080:80 alpine:latest
Answer: A
Explanation:
To create a running container based on a tagged Docker image with the container port 8080 bound to port 80 on the host, you use the docker run command with the -p flag.
A: docker build -p 8080:80 alpine
- Incorrect. docker build is used to build an image, not run a container. B. docker exec -p 8080:80 alpine
- Incorrect. docker exec is used to run a command in a running container. C. docker start -p 8080:80 alpine
- Incorrect. docker start starts a stopped container but does not create one. D. docker run -p 8080:80 alpine
- Correct. This command runs a new container from the image and maps the ports.

Refer to the exhibit. An engineer is comparing two files by using the unified diff format. Which cade snippet belongs to the new.py file?
- A.
- B.
- C.
- D.
Answer: D
Explanation:

NEW QUESTION # 191 
Refer to the exhibit. An engineer runs a network that consists of Cisco Nexus devices. The network is distributed between data centers in different locations. The switches are configured using standalone connections and a single point of failure. Which process is being automated by the Ansible playbook?
- A. executing HSRP configuration from the Ansible controller node
- B. enabling HSRP on the rtr-1a inventory host
- C. enabling HSRP on the nxos_rtr inventory host
- D. executing HSRP configuration from the srv-1a inventory host
Answer: C
Explanation:
The Ansible playbook in the exhibit is designed to automate the configuration of HSRP (Hot Standby Router Protocol) on a Cisco Nexus switch listed in the nxos_rtr inventory group. Here's what the playbook does:
* Hosts: The playbook is targeting nxos_rtr hosts.
* Task: The task uses the nxos_hsrp module to configure HSRP.
* Parameters: Various parameters such as group, VIP, priority, interface, authentication, and version are set for HSRP configuration.
* Delegation: The configuration is delegated to the srv-1a inventory host, but it is still targeting the nxos_rtr for the actual HSRP configuration.
Therefore, the playbook is enabling HSRP on the nxos_rtr inventory host.

NEW QUESTION # 192
Refer to the exhibit. What does the python function do?
- A. It returns DNAC user and password.
- B. It returns HTTP Basic Authentication.
- C. It reads a token from a local JSON file and posts the token to the DNAC URL.
- D. It returns an authorization token.
Answer: D

NEW QUESTION # 193
What is the purpose of grouping devices in a VLAN?
- A. Multicast network traffic is limited to the VLAN connected devices.
- B. Devices communicate as if they are connected on the same wire.
- C. Unicast messages are limited to the clients connected on the same VLAN.
- D. Network traffic is load balanced between the devices connected to the VLAN.
Answer: B
Explanation:
The primary purpose of grouping devices in a VLAN (Virtual Local Area Network) is to segment a network such that devices within the same VLAN can communicate as if they are on the same physical network, regardless of their actual physical location. This allows for logical grouping of devices, providing improved network management and security.

What is a characteristic of the Cisco Finesse platform?
- A. The platform provides a ready-to-go platform for HD video and audio conferencing.
- B. The platform includes an enterprise-class IM engine.
- C. Applications are added to the platform from the desktop remotely.
- D. Applications allow services to be invoked on a network triggered event.
Answer: D
Explanation:
Explanation
A characteristic of the Cisco Finesse platform is that applications allow services to be invoked on a network triggered event. Cisco Finesse is a next-generation agent and supervisor desktop designed to provide a rich, browser-based experience for contact center agents and supervisors. It offers a flexible, open development platform that allows developers to build custom applications and integrations to meet the specific needs of their contact center. One of the key features of Cisco Finesse is the ability to trigger actions based on events within the contact center network, such as an incoming call or a change in the status of a customer's account.
This allows developers to build applications that can react to real-time events and provide relevant information or services to agents as they handle customer interactions.

When a Cisco IOS XE networking device is configured by using RESTCONF, what is the default data encoding method?
- A. application/xml-data+json
- B. application/yang-data+json
- C. application/json-data+xml
- D. application/yaml-data+json
Answer: B
Explanation:
When configuring a Cisco IOS XE networking device using RESTCONF, the default data encoding method is application/yang-data+json. This MIME type indicates that the data is encoded in JSON format and structured according to YANG data models. YANG (Yet Another Next Generation) is a data modeling language used to model configuration and state data manipulated by the NETCONF protocol, which RESTCONF leverages.

What is the purpose of running tests before writing code in test-driven development?
- A. to provide proof of the work carried out
- B. to ensure that the tests pass
- C. to demonstrate that the tests fail for expected reasons
- D. to find unexpected failures in the tests
Answer: C
Explanation:
In Test-Driven Development (TDD), developers write tests before writing code. The purpose of running the tests before writing code is to demonstrate that the tests fail for expected reasons.
This is because the tests are written to test the functionality that the developer is about to add to the codebase, and since that functionality does not yet exist, the tests should fail. This is an important step in the TDD process because it confirms that the tests are correctly identifying the missing functionality and that they are not passing due to an error in the tests themselves.

- A. git merge-file
- B. git bisert
