Question 1

Which Cisco DevNet resource allows access to products in a development lab to explore, learn, and build application that use Cisco APLs?

ADevNet communities

BDevNet code Exchange

CDevNet Automation Exchange

DDevNet sandbox

Answer : D

The Cisco DevNet Sandbox is a resource provided by Cisco that allows developers to access a variety of Cisco products in a development lab environment. This resource enables users to explore, learn, and build applications using Cisco APIs. The sandbox environment is equipped with pre-configured topologies and a range of Cisco technologies, offering a safe and secure space to experiment without the need for physical hardware.

DevNet Sandbox: Provides access to virtual environments for learning and development.

DevNet Communities: Are for discussions and collaboration among developers.

DevNet Code Exchange: Offers code repositories and examples for various Cisco technologies.

DevNet Automation Exchange: Focuses on automation scripts and tools shared by the community.

Question 2

Refer to the exhibit.

Which device limits traffic between server 1 and server 2?

ADevice B

BDevice C

CDevice D

DDevice E

Answer : D

In the provided network topology, Device E is positioned between Server 1 and Server 2. Device E, being a Layer 2 switch, will limit traffic between these servers by making forwarding decisions based on MAC addresses. If there are VLANs configured, Device E will ensure that traffic is segregated accordingly, allowing only specific traffic to pass between the servers as defined by the network policies.

Question 3

Refer to the exhibit.

What does the python function do?

AIt returns DNAC user and password.

BIt returns HTTP Basic Authentication.

CIt returns an authorization token.

DIt reads a token from a local JSON file and posts the token to the DNAC URL.

Answer : C

The Python function shown in the exhibit performs the following operations:

It defines a function get_result().

Inside the function, it sets the url variable to the Cisco DNA Center (DNAC) API endpoint for authentication tokens.

It makes a POST request to the specified URL with HTTP Basic Authentication using the credentials DNAC_USER and DNAC_PASSWORD.

The response from the POST request is expected to be in JSON format.

It extracts the value associated with the key 'Token' from the JSON response.

Finally, it returns this token.

This function's purpose is to obtain and return an authorization token from the Cisco DNA Center API, which can be used for subsequent API requests.

Question 4

What is a comparison of YAML and JSON?

AYAML has a more consistent approach to representing data compared to JSON.

BJSON does not support comments and YAML does.

CYAML is a more verbose data structure compared to JSON.

DJSON has more common usage in configuration management tools compared to YAML.

Answer : B

YAML and JSON are both data serialization formats often used in configuration files. One of the key differences is that YAML supports comments, whereas JSON does not.

Comments: YAML allows comments, which makes it easier to add explanatory notes within the configuration files.

Data Representation: Both formats are used to represent data structures, but YAML is often considered more human-readable.

Option B is correct as it highlights the difference that YAML supports comments while JSON does not.

Question 5

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?

Adocker build -p 8080:80 alpine:latest

Bdocker exec -p 8080:80 alpine:latest

Cdocker start -p 8080:80 alpine:latest

Ddocker run -p 8080:80 alpine:latest

Answer : D

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.

Docker Run Command

Question 6

What operation is performed with YANG model-driven programmability in NX-OS?

Aconfigure a device with native and OpenConfig-based models

Bsend CLI commands to a device and retrieve output in JSON format

Crun Linux commands natively on the device

Dbootstrap a device that has a factory-default configuration

Answer : A

YANG model-driven programmability allows for the configuration of devices using data models. In NX-OS, this includes both native and OpenConfig-based models.

YANG Models: These are used to model configuration and state data for network devices. Native models are specific to the vendor, while OpenConfig models are vendor-neutral.

Configuration Management: YANG models facilitate consistent and programmable configuration of network devices, which can be done through APIs like NETCONF or RESTCONF.

Question 7

A company has written a script that creates a log bundle from the Cisco DNA Center every day. The script runs without error and the bundles are produced. However, when the script is run during business hours, report poor voice quality of phones calls. What explains this behavior?

AThe application is running in the Voice VLAN and causes delays and jitter in the subnet.

BThe speed and duplex settings in Cisco DNA Center are sot incorrectly, which causes the transfer to be too slow.

C9 The script is written in a low-level programming language where there is no memory safety. This causes a buffer overflow and disruption on the network.

DGenerating the logs causes the CPU on the network controller to spike, which causes delays m forwarding the voice IP packets.

Answer : D

Generating log bundles is a resource-intensive task that can cause high CPU utilization on the Cisco DNA Center. When the CPU spikes, it can affect the performance of other critical tasks, such as forwarding voice IP packets, leading to delays and poor voice quality. This is especially noticeable during business hours when network utilization is high, and voice traffic is sensitive to latency and jitter. More details can be found in Cisco DNA Center documentation on Managing Logs and System Performance.
