Refer to the Exhibit. A customer reports that they cannot access your organization's website. Which option is a possible reason that the customer cannot access the website?

Excessive bandwidth consumption by an internal server would degrade or slow access for all users but would not produce a clean external block; this describes resource exhaustion rather than an access control action.

A virus on the server is an internal security finding and does not by itself cause external customers to be blocked from connecting to the website.

A vulnerability scanner result indicating compromise is an internal assessment output and does not directly result in external parties blocking customer access to the site.

Internet sensors operated by threat intelligence services such as Cisco Talos can identify and report outbound traffic from an IP as malicious. Once flagged, that IP address may be added to reputation blocklists consumed by upstream ISPs, firewalls, and DNS resolvers, causing customer connections to the website to be silently dropped or refused. This external reputation-based blocking is a direct and realistic cause for customers being unable to access the organization's site even when the server itself is technically online.
