allows for separation of application that traditionally run in the same host

natively secures access to secrets that are used by the running application

The server cannot find the requested resource because the path specified is incorrect

"The server cannot process the request as it has detected an issue in the request syntax or body

The request has not been accepted because it requires authentication

def get_result()

url="https://sandboxdnac.cisco.com/dna/system/api/v1/auth/token"

A script that creates a log bundle from the Cisco DNA Center every day, runs without error and the bundles are produced, but when the script is run during business hours, report poor voice quality of phones calls. Choose the correct reason for this.

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

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

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."

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

Choose options that describe the purpose of a revision control system such as Git (Choose two.)

Keep all files in the same place

Track who made changes

Enforce file formatting.

Create packages for distribution from source code

Keep historic versions of a file.

Choose the purpose of the Cisco VIRL software tool

automate API workflows

test performance of an application

verify configurations against compliance standards

simulate and model networks

Choose the difference between a synchronous API operation from an asynchronous one.

for synchronous API operation, clients receive responses with a task id for further processing

for synchronous API operation, clients poll for the status of the execution of operations"

for synchronous API operation, clients subscribe to a webhook for operation results

for synchronous API operation, clients can access the results immediately

Choose correct options that are reasons that the use of APIs is growing (Choose two.)

with APIs, computations are performed faster

There are very few use cases for integration with other applications

they allow for reuse of server code to service different clients like mobile, web, and so on.

they solve challenges presented by an unreliable network

they enable developers to use cloud services

Choose the correct option for the statementWith client-side rate limiting, you limit the rate of API requests, while with payload limiting, you limit the size of the API response bodies

False

True

Choose the correct elements that will fill the blanks in option blanks of the following code excerpt

curl -x ...........Option 1 ............. -H " .................Option 2 ................... : application/json" \ -H " .....Option 3 ....... : Bearer

1 DELETE

2 Deny

3 Authentication

1 GET

2 Accept

3 Authorization

1 PUT

2 Authentication

3 json

1 PUT

2 Accept

3 data

If a call from REST API expects a result set of more than 1000 records and each time only 50 of them are returned, choose the feature that is limiting the returned amount of data

payload limit

service timeouts

pagination

rate limiting

Choose the deployment model that uses host operating system features to provide an isolated environment for multiple tenants to run applications on the same server

containers

virtual machines

none of them

bare-metal servers

Choose the possible the start of a chunk from a unified diff

self.assertEqual(a,b)

self.assertSameValue(a,b)

Choose benefits of the Model-view-controller software design pattern (Choose two.)

it simplifies network automation

it separates responsibilities of the code

it allows for multiple views of the same model

it makes code easier to deploy using Cl/CD pipelines

it reduces need for error handling

Choose the characteristics of Bare Metal environments that are related to application deployment (Choose two.)

If updates from a local server fail to download, but the same updates work when a much slower external repository is used, then choose the reason the local updates are failing
