Refer to the exhibit. Which security incident is causing a drop in website availability?

Question

Options

• Anetwork forwarding loss between the 10.40.225.2, 10.40.225.3, and 10.40.225.1 devices
• Bnetwork end-to-end loss between the 10.40.225.2, 10.40.225.3, and 10.40.225.1 devices
• Cnetwork outage between the 10.40.225.2, 10.40.225.3, and 10.40.225.1 devices
• Dnetwork degradation between the 10.10.10.1, 10.40.225.2, and 10.40.225.3 devices

• A
  69% (27)
• B
  10% (4)
• C
  5% (2)
• D
  15% (6)

Explanation

Option A is correct because the exhibit shows packet forwarding failures specifically within the forwarding plane of the 10.40.225.1, .2, and .3 devices - meaning those devices are receiving packets but failing to forward them onward, which directly degrades website availability rather than eliminating it entirely.

Option B is wrong because end-to-end loss describes packet loss measured across the full source-to-destination path, not a localized incident at specific forwarding devices - it's a measurement metric, not the root cause incident shown.

Option C is wrong because an outage implies complete connectivity failure, whereas the scenario describes a drop (partial degradation) in availability; a full outage would remove the site entirely, not just reduce it.

Option D is wrong because it references the wrong device set - 10.10.10.1 is not among the affected devices shown in the exhibit; the incident is isolated to the 10.40.225.x subnet devices.

Memory tip: Think of it this way - "forwarding loss" targets the data plane (how packets move through a device), so it causes partial availability drops rather than a full outage. On the exam, when you see a drop (not a complete failure) tied to specific devices, look for forwarding-plane issues first.
