• Question 112:

  A customer uses URL authentication to prevent unauthorized access to customer services and makes the following request:

  http://www.test.com/Filenamey-efeabcdefaac7d15edfc6ec8aeffee2cb

  When the CDN server receives this request, which of the following checks will be performed? (Choose three)

  A. Referer check: The Referer field in the request header is empty. The CDN node returns an HTTP 403 error.
  B. Encrypted string verification: After time verification is passed, the string is constructed in sstring mode. The MD5 algorithm is then used to calculate the HashValue, which is compared with the md5hash included in the user's request. If they match, authentication succeeds and the file is returned; otherwise, authentication fails and an HTTP 403 error is returned.
  C. Authentication parameter check: Verify whether authentication parameters are included. If no authentication parameters are carried, the request is considered invalid and an HTTP 403 error is returned.
  D. Time verification: Determine whether the current system time falls within the valid interval. If it exceeds this range, the request is considered expired and an HTTP 403 error is returned.
  B. Encrypted string verification: After time verification is passed, the string is constructed in sstring mode. The MD5 algorithm is then used to calculate the HashValue, which is compared with the md5hash included in the user's request. If they match, authentication succeeds and the file is returned; otherwise, authentication fails and an HTTP 403 error is returned.

  B. Stopped status: It may be that the Agent was manually stopped.
  C. Not started status: It may be that the Agent is not installed on the ECS or the Agent was manually stopped.
  D. Configuration abnormal: It may be caused by a configuration error in the default NIC security group rule of the ECS.
  A. Fault status: When the server does not receive the Agent heartbeat for 1 minute, the Agent status is displayed as "fault."
