Devnet Final 61-80

Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to an external server at the IP address 209.165.200.254 across a router R1 that is running dynamic NAT. (Not all options are used.)

• 
• 

A network administrator can successfully ping the server at www.cisco.com, but cannot ping the company web server located at an ISP in another city. Which tool or command would help identify the specific router where the packet was lost or delayed?

• • traceroute

• • ipconfig

• • telnet

• • netstat

Which two HTTP functions correspond to the UPDATE function in CRUD? (Choose two.)

• • POST

• • DELETE

• • PATCH

• • PUT

• • GET

Match the term to the RESTAPI request http://example.com/update/person?id=42&email=person%40example.com. (Not all options are used.)

• 
• 

Which HTTP status code category is used in the response to indicate that a REST API request contains an error on the client side?

• • 1xx

• • 2xx

• • 3xx

• • 4xx

• • 5xx

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 the error?

• • The protocol is wrong.

• • The resource path is wrong.

• • The SSL certificate is invalid.

• • The destination web host address is invalid.

What are two requirements for an application to communicate with a webhook provider? (Choose two.)

• • The application must support JSON.

• • The application must always be running.

• • The application must register a URL with the webhook provider.

• • The host where the application is running must have an SSH client installed.

• • The host where the application is running must have an SSH server running.

A student is learning network automation by using a REST API. The student sends a request to a network device and receives a response with the status code of 202. What does this status code mean?

• • The request was understood but has been rejected by the server.

• • The request was successful and typically includes a payload.

• • The request has been accepted for processing, but the processing has not been completed.

• • Because of a server error, the request cannot be fulfilled.

What are two characteristics of stateless applications? (Choose two.)

• • They must run on container orchestrators like Kubernetes.

• • They can be freely scaled across available capacity without disrupting ongoing customer connections.

• • They can be scaled only by redeploying them and destroying the data that users or operators previously needed.

• • They maintain the user state within the local user machine so that automation can work non-destructively.

• • They can store a user state in an accessible database separate from application servers and other components.

What is a characteristic of the continuous integration component of the CI/CD philosophy for software development?

• • Code changes are continually merged with the main branch of the application, so change sets are small.

• • Code changes are tested and integrated with the main branch then tested again before they are deployed into production.

• • Code is constantly deployed into production where users serve as the final testers.

• • Application development is performed in short sprints so that enough code is always in a deployable state.
