Final answer:
The correct answer for monitoring cloud traffic across all resources in a VPC is not clearly provided in the choices. Typically, a cloud provider's native tool like AWS VPC Flow Logs would be the answer, but this isn't listed as an option.
Step-by-step explanation:
The tool that can monitor cloud traffic across all resources hosted in a Virtual Private Cloud (VPC) is not explicitly listed among the options (Wireshark, Packet Broker, Explicit Tagging, Syslog). However, for cloud environments, especially in AWS, one would typically use flow log tools integrated within the cloud service provider's platform. For example, AWS offers VPC Flow Logs for this purpose. The listed options each have their use cases, but none of them inherently monitor all VPC traffic:
- Wireshark is a network protocol analyzer that's useful for capturing and analyzing packet data directly from network interfaces, but not inherently used across cloud resources.
- A packet broker is generally a device or service that distributes network traffic to various monitoring tools but does not monitor traffic itself.
- Explicit tagging refers to assigning specific tags to traffic or resources for identification but isn't a monitoring tool.
- Syslog is a protocol used for system logging and not for monitoring traffic per se.
