Azure Load Balancer

Layer 4 internal/public traffic distribution, probes, and rules.

Key points

  • Layer 4 distribution using public or internal frontend configurations.
  • Backend pools list targets and health probes determine eligibility for new flows.
  • Rules map frontend protocol and port to backend protocol and port.

Best-known use cases

  • Distribute private TCP traffic across VMs.
  • Publish a public regional service across healthy backends.

What candidates often confuse it with

  • Public vs internal Load Balancer: internet frontend vs private VNet frontend.
  • Load Balancer vs Azure DNS: distribute flows to healthy targets vs resolve a name to an address.

Key takeaway

Configure frontend, rule, probe, pool, and backend path as one complete Layer 4 load-balancing chain.

Mode

Exam fidelity: Microsoft does not publish a fixed live question count or guarantee a question-type mix for AZ-104. This lane counts multiple-choice and multiple-response items as exam-style practice. Ordering, matching, and case-study items are supplemental site exercises and do not count toward exam-style accuracy. Practice percentages do not reproduce Microsoft's scaled scoring, and difficulty labels describe this site's Intermediate-level scenario complexity rather than a Microsoft-published question rating.
