Question - 67 : - What is the difference between Assert and Verify commands in Selenium?
Answer - 67 : -
The difference between Verify and Assert commands in Selenium are:
- The verify commands determine whether or not the provided condition is true. The program execution does not halt regardless of whether the condition is true or not, i.e., all test steps will be completed, and verification failure will not stop the execution.
- The assert command determines whether a condition is false or true. To know whether the supplied element is on the page or not, we do the following. The next test step will be performed by the program control, if the condition is true. However, no further tests will be run, and the execution will halt, if the condition is false.

Question - 69 : - Why are SSL certificates used in Chef?
Answer - 69 : -
SSL certificates are used between the Chef server and the client to ensure that each node has access to the right data.
Every node has a private and public key pair. The public key is stored at the Chef server.
When an SSL certificate is sent to the server, it will contain the private key of the node.
The server compares this against the public key in order to identify the node and give the node access to the required data.
