Which of the following is not a protocol which can be used when monitoring an endpoint using Route53 health checks.
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - D.
The method that you want Amazon Route 53 to use to check the health of your endpoint:
· HTTP - Amazon Route 53 tries to establish a TCP connection.
If successful, Amazon Route 53 submits an HTTP request and waits for an HTTP status code of 200 or greater and less than 400.
· HTTPS - Amazon Route 53 tries to establish a TCP connection.
If successful, Amazon Route 53 submits an HTTPS request and waits for an HTTP status code of 200 or greater and less than 400.
· TCP - Amazon Route 53 tries to establish a TCP connection.

http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/health-checks-creating.htmlRoute53 is an Amazon Web Services (AWS) service that offers scalable DNS (Domain Name System) web services. Route53 health checks is a feature of the Route53 service which allows the monitoring of endpoints by checking their availability and responsiveness to different types of requests.
When monitoring an endpoint using Route53 health checks, it is possible to use different protocols to send the request and receive a response. The available protocols are:
A. HTTP (Hypertext Transfer Protocol): HTTP is a protocol that is commonly used for transmitting data over the internet. It is used by web browsers to communicate with web servers to retrieve web pages and other content.
B. HTTPS (Hypertext Transfer Protocol Secure): HTTPS is a more secure version of HTTP, which uses encryption to protect data transmitted between a web browser and a web server.
C. TCP (Transmission Control Protocol): TCP is a protocol that establishes a reliable connection between two endpoints, allowing the transmission of data in both directions.
D. UDP (User Datagram Protocol): UDP is a protocol that does not establish a reliable connection between two endpoints. Instead, it sends data in small packets, which may be lost or arrive out of order.
Based on the options provided in the question, it can be inferred that the correct answer is option D (UDP). UDP is not a protocol that can be used when monitoring an endpoint using Route53 health checks. The reason for this is that UDP does not establish a reliable connection, which can result in lost or incomplete data.
In contrast, TCP and HTTP/HTTPS are reliable protocols that can be used to monitor endpoints, ensuring that the data being transmitted is complete and accurate.
