Hello, network-trailblazers! Bit here, perched on a branch overlooking your VPC forest. Today we’re going to explore a powerful tool that helps you see the paths between your AWS network components—whether within one VPC, across peering, or even hybrid setups. The tool? VPC Reachability Analyzer!

If you’re prepping for the Advanced Networking exam, you’ll want to know how to use this service for visibility, validation, and troubleshooting of your AWS (and hybrid) network connectivity.

Hey network adventurers! Bit here, squeaking from the treetops with my acorn of observability. Today we’re going deep on two powerful visibility tools in AWS: Flow Logs and Traffic Mirroring. If you’re preparing for the AWS Advanced Networking exam, you’ll want to know when to use each, what they show, and how they differ—especially when you’re managing hybrid or complex networks.

Hello, visibility voyagers! Bit here, perched in the treetops of your cloud architecture. Today we’re grabbing our binoculars and diving into access logs—the detailed logs you capture from AWS services so you can trace who did what, when, and how. For the AWS Advanced Networking Exam, you’ll want to know which services produce access logs, what those logs capture, and how they fit into network design and monitoring.

Hey there, network explorers! Bit the Chipmunk here — reporting live from deep within the AWS forest of logs, metrics, and alarms! 🌲

In Domain 1.4 of the AWS Certified Advanced Networking – Specialty exam, we’re not just flipping switches to “turn on logging.” Nope! We’re designing systems that answer key operational questions:

• Who accessed what?
• What changed?
• Is it healthy?
• And when did that latency spike start?! 😱

Hey there, network watchers! Bit here, perched high in the branches of your cloud infrastructure. Today we’re going to dig into the “what to monitor” part—meaning which metrics you should pick so you can keep your network healthy, performant and ready for global/hybrid scale. If you’re prepping for the AWS Advanced Networking exam, this is one of the nuts you’ve got to crack.
