2.        

 

Refer to the exhibit. A network administrator is using a Python script to send a REST API request. What is the purpose of the line of code resp = requests.get(url, verify = False) ?

 It omits the sending URL in the response.

 It tests the function of the Python requests library.

 It bypasses the certificate validation check. (True)

 It skips the URL verification step and tests the resource path

 

3.       3Which characteristic of the SOAP architecture specifies communication between all similar and dissimilar application types?

Independence (True)

 extensibility

 neutrality

 interface uniformity

 

4.       What is the meaning of the term flow as it relates to the OAuth 2.0 authorization framework?

 

It is a process for an API user to obtain an access token from the authorization server. (True)

It is the number of requests contained in the token bucket.

It is a process for an API request to send authentication credentials to a web service.

It is the sequence of data exchanged between a REST API request and a response.

 

5.       Which type of credential information is used for the bearer authentication in REST APIs?

 a string generated by an authentication server (True)

 a username and password set by the client

 an MD5 hash string generated by the client application

 a password encoded using Base64

 

 

 

6.       Which API architectural style uses an XML-based messaging protocol to communicate between applications?

SOAP (True)

XML-RPC

NFS

REST

 

7.       Which SOAP message root element defines the XML document as a SOAP message?

 Meta tag

 Body

 Envelope (True)

 Header

 

8.        


Refer to the exhibit. A network administrator is using a Python script to test a REST API request. The traceback message indicates that there is an error in the URI. What is a possible issue?

 

The query component is missing.

The destination host address is wrong. (True)

The protocol is wrong.

The SSL certificate is invalid.

to limit the number of passwords that a client can have in making API requests

 to avoid a server overloading from too many requests at the same time (True)

 to ensure a client uses a multifactor authentication mechanism

 to limit the number of authorization requests per API call
