Question 1

A developer needs to prepare the file README.md in the working tree for the next commit operation using Git. Which command needs to be used to accomplish this?

Agit add README.md staging

Bgit -a README.md

Cgit add README.md

Dgit commit README.md

Answer : C

To prepare the file README.md in the working tree for the next commit operation in Git, the command git add README.md should be used. This command stages the file, meaning it adds the file's current content to the staging area, which is a preparatory step before committing it to the repository.

git add README.md: Adds the README.md file to the staging area.

git commit README.md: Commits all staged changes (not just README.md unless it is the only file staged).

Question 2

Which standard supported by Cisco IOS XE and Cisco NX-OS is used for automating the configuration of multiple devices across a network?

ASNMP -- YANG

BSYSLOG -- YANG

CCLI -- YANG

DNETCONF -- YANG

Answer : D

NETCONF (Network Configuration Protocol) is a standard used for network device configuration, and it utilizes YANG (Yet Another Next Generation) as a data modeling language. Cisco IOS XE and Cisco NX-OS support NETCONF and YANG to automate the configuration and management of network devices across a network. YANG defines the data models, while NETCONF provides the protocol to manipulate these models.

Question 3

Which type of webhooks must be configured to receive all the events that relate to a specific system?

Abroadwork

Bbroadcast

Cfallback

Dfirehose

Answer : D

Question 4

What is a characteristic of RPC APIs compared to REST APIs?

AAuthentication is done over provisions for the service caller and vice versa for RPC API, and REST API uses HTTP headers for authentication.

BAll communications between the client and server must be stateless for RPC API, and REST API is stateful.

CThe architecture model for RPC API is resource-focused, and REST API is procedure-focused.

DThe data payload must be in JSON format for RPC API, and REST API allows JSON and XML formats.

Answer : A

RPC (Remote Procedure Call) APIs and REST (Representational State Transfer) APIs have different approaches to communication and authentication.

RPC APIs: Authentication can be more complex and is often embedded within the service calls themselves, sometimes requiring specific provisions for the caller and the service.

REST APIs: Authentication typically relies on standardized methods such as HTTP headers, including Basic Auth, OAuth tokens, or API keys, making it more straightforward and standardized across different services.

Question 5

An engineer creates a script that makes calls to the Cisco Webex API to create a new room and then add users to the room. The engineer runs the script and receives an HTTP response with status code 200. The engineer wants to make an enhancement to the script to send an email to the added users that includes the title and ID of the room. Which part of the HTTP response contains the additional information?

Aresponse body

Bresponse header

Cresponse content-type

Dresponse status code

Answer : A

Question 6

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 7

Refer to the exhibit.

An API call is constructed to retrieve the inventory in XML format by using the API. The response to the call is 401 Unauthorized. Which two headers must be added to the API call? (Choose two.)

AOption A

BOption B

COption C

DOption D

EOption E

Answer : C, E

The 401 Unauthorized response indicates that the API call lacks proper authentication. To authenticate a request using a Bearer token, the correct headers must be included. The 'Authorization: Bearer <token>' header is the correct format for including a Bearer token in an API request. Additionally, specifying the correct content type can also be important, but in this case, the critical headers are related to authorization.
