  1. The l-TAG in the l-SID is inspected to determine where the frame should be delivered.
  2. When the B-MAC header is stripped the customer MAC address is then looked up in the FDB
  3. The l-SID in the l-TAG is inspected to determine where the frame should be delivered.

If the max remote-age timer of a B-VPLS is reached, what happens to the remotely learned MAC addresses in the l- VPLS service?

  1. There is no effect. The MAC addresses for the l-VPLS age out independently of the aging of B-VPLS addresses.
  2. The MAC addresses for the l-VPLS will age out immediately following the remote-age out of the backbone-macs of the B-VPLS.
  3. By default, the remote-age timer of the B-VPLS is configured to 0 and addresses do not age out. The l-VPLS uses its own timer.
  4. The same timer is used for B-VPLS and l-VPLS addresses on the node.

Question 2:

  • Answer: D. Azure Advisor

  • Why: To view security-related recommendations for resources in the Compute and Apps area (including App Service Web Apps and Functions), you use Azure Advisor. Advisor surfaces personalized best-practice recommendations across resources, including security, and shows which resources are affected and the severity.

  • Why not the others:
- Azure Log Analytics is for ad-hoc querying of telemetry, not for viewing security recommendations. - Azure Event Hubs is for streaming telemetry data, not for security recommendations.
  • Quick tip: In the portal, navigate to Azure Advisor and check the Security recommendations for App Services to see actionable items and affe

The DP-900 exam can be tricky if you aren't familiar with Microsoft’s specific cloud terminology. I used the practice questions from free-braindumps.com and found them incredibly helpful. The site breaks down core data concepts and Azure services in a way that actually mirrors the real test. As a resutl I passed my exam.
