Question 10

The script returns an output of 401. To use the supplied URL. an HTTP GET request must Be sent with an Authorization

header. The header value is a BaseG4 encoded concatenation of the username and password. Which action must be

taken to return an output of 200?

A. Change the verify=False setting in the request to verify=True to enable HTTP Basic authentication

B. Modify the method from LOGIN to GET and supply the username ;password value as JSON payload

C. Verify that the username and password values imported from the configuration file ate still valid.

D. Insert an Authorization header with the values username password from the supplied configuration file.

Correct Answer: B

This seems like a trick question. Simply changing "login" to "get" should fix it. You\\'re still keeping the HTTPBasicAuth

header intact while also sending the user/pass in the json payload according to this answer. Sending it in the payload

shouldn\\'t do anything since it\\'s a simple GET. The payload will be ignored and the basic auth header will be used.

Question 11

A developer pushes an application to production. The application receives a webhook over HTTPS without a secret. The

webhook information contains credentials to service in cleartext. When the information is received, it is stored in the

database with an SHA-256 hash. Credentials to the database are accessed at runtime through the use of a vault

service. While troubleshooting, the developer sets the logging to debug to view the message from the webhook. What is

the security issue in this scenario?

A. Database credentials should be accessed by using environment variables defined at runtime.

B. During the transport of webhook messages, the credentials could be unencrypted and leaked.

C. During logging, debugging should be disabled for the webhook message.

D. Hashing the credentials in the database is not secure enough; the credentials should be encrypted.

Correct Answer: B

Question 12

What is the impact on an application from having a large distance between a client device and a host server?
