AWS Certified SysOps Administrator – Associate (legacy) — Question 18

In configuring an Amazon Route 53 health check, a SysOps Administrator selects `˜Yes' to the String Matching option in the Advanced Configuration section. In the
Search String box, the Administrator types the following text: /html.
This is to ensure that the entire page is loading during the health check. Within 5 minutes of enabling the health check, the Administrator receives an alert stating that the check failed. However, when the Administrator navigates to the page, it loads successfully.
What is the MOST likely cause of this false alarm?

Answer options

• A. The search string is not HTML-encoded.
• B. The search string must be put in quotes.
• C. The search string must be escaped with a backslash (\) before the forward slash (/).
• D. The search string is not in the first 5120 bytes of the tested page.

Correct answer: D

Explanation

The most likely reason for the false alarm is that the search string '/html' is not located within the first 5120 bytes of the page, which is the limit that Route 53 checks. The other options refer to formatting issues that would not cause a false positive, as the check would still run regardless of those conditions.
