Module lab: Troubleshoot an internal load balancer

لاب الدرس: حل مشاكل Internal load balancer

The app tier sits behind internal load balancer app-ilb (frontend 10.50.1.100) but every request fails. A colleague configured the health probe on the wrong port and someone added a deny rule to app2 's NIC NSG. Find and fix both problems using Backend health and effective security rules, then add session persistence and a management NAT rule.

The 4 tasks you will do

• Task 1 — Fix the health probe portالمهمة 1 — صلّح بورت الـ Health probe
• Task 2 — Remove the NSG rule that blocks probes on app2المهمة 2 — شيل الـ NSG rule اللي مانعة الـ Probes على app2
• Task 3 — Configure session persistenceالمهمة 3 — ظبط الـ Session persistence
• Task 4 — Add an inbound NAT rule for SSH to app1المهمة 4 — ضيف Inbound NAT rule للـ SSH على app1

The lesson it belongs to

• Configure internal and public load balancers and troubleshoot load balancing
