Exam AZ-700 topic 2 question 21 discussion

C. Azure Standard Load Balancer that has high availability (HA) ports enabled App1 is installed on 10 VMs which can be put in a Backend pool. The req is to minimize the number of load balancing rules. If you select HA it will allow you to have 1 rule for TCP and UDP ports, if you don't select HA you will need to have a minimum of 2 rules for TCP and UDP with a * range.

As stated in https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-ha-ports-overview Load balance a large number of ports You can also use HA ports for applications that require load balancing of large numbers of ports. You can simplify these scenarios by using an internal standard load balancer with HA ports. A single load-balancing rule replaces multiple individual load-balancing rules, one for each port.

C is correct

C is correct When you enable high availability (HA) ports on the load balancer, it creates a single rule for all the ports of the virtual machines in the back-end pool.

Here the requirement is on TCP and UDP ports, not HTTP or HTTPS, hence application gateway is ruled out. Incorrect Answer B: Some application scenarios prefer or require the same port to be used by multiple application instances on a single VM in the backend pool. Common examples of port reuse include: clustering for high availability network virtual appliances exposing multiple TLS endpoints without re-encryption. If you want to reuse the backend port across multiple rules, you must enable Floating IP in the rule definition. https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-floating-ip Correct Answer is C: - The HA ports load-balancing rules are configured when you set the front-end and back-end ports to 0 and the protocol to All. The internal load balancer resource then balances all TCP and UDP flows, regardless of port number https://learn.microsoft.com/en-us/azure/load-balancer/load-balancer-ha-ports-overview

C is correct

C is correct

C. https://docs.microsoft.com/en-us/azure/application-gateway/application-gateway-faq. UDP is layer 4. Application gateway is layer 7.

Application gateway does not support UDP protocol. In order to minimize the number of load-balancing rules, HA ports load-balancing rule should be used.
