Load balancing

Azure Load Balancer

Regional Layer 4 load balancing for TCP and UDP flows.

Key points

  • Load Balancer distributes regional TCP or UDP flows using Layer 4 rules and health probes.
  • Frontend IPs, backend pools, probes, rules, outbound design, zone scope, and session behavior determine availability.

Best-known use cases

  • Balance internal TCP connections across healthy regional backend instances.

What candidates often confuse it with

  • Load Balancer is regional Layer 4; Application Gateway and Front Door provide Layer 7 application delivery.

Key takeaway

Choose Load Balancer when regional non-HTTP or transport-level balancing is required.

Mode

Exam fidelity: Microsoft does not publish a fixed live question count or guarantee a question-type mix for AZ-305. This lane contains multiple-choice exam-style practice; no supplemental matching, ordering, or case-study exercises were needed. Practice percentages do not reproduce Microsoft's scaled scoring, and difficulty labels describe this site's Expert-level architecture and trade-off complexity rather than a Microsoft-published question rating.
