Exam AZ-304 topic 5 question 42 discussion

the answer is correct

i would like to add emphasis also

If the backend pool contains multiple servers, the application gateway uses a round-robin algorithm to route the requests between healthy servers. https://learn.microsoft.com/en-us/azure/application-gateway/how-application-gateway-works#:~:text=a%20health%20probe.-,If%20the%20backend%20pool%20contains%20multiple%20servers%2C%20the%20application%20gateway%20uses%20a%20round%2Drobin%20algorithm%20to%20route%20the%20requests%20between%20healthy%20servers.,-This%20load%20balances

D is correct. Others are non HTTPS

Answer is D

Application Gateway supports autoscaling, TLS offloading, and end-to-end TLS, a web application firewall (WAF), cookie-based session affinity, URL path-based routing, multisite hosting, and other features. Application Gateway is a layer 7 load balancer, which means it works only with web traffic (HTTP, HTTPS, WebSocket, and HTTP/2). It supports capabilities such as TLS termination, cookie-based session affinity, and round robin for load-balancing traffic. Load Balancer load-balances traffic at layer 4 (TCP or UDP). Application Gateway provides Transport Layer Security (TLS) protocol termination ("SSL offload") or per-HTTP/HTTPS request. Answer is D

Azure Front Door HTTP(S) Traffic Manager non-HTTP(S) Application Gateway HTTP(S) Azure Load Balancer non-HTTP(S) only Front Door and Application Gateway support HTTPs and TSL/SSL offload Front door also support round robin using weighted routing method, Front Door will round robin the traffic among the final selected pool of backends in the ratio of weights specified. Answer is correct as Front Door is there.

All of these below threads did not emphasize that empahsis gave an overkill feature as the answer. Even though we all know that all 3 listed features (HTTPS, Round Robin & SSSL Offlaoding) can be fulfiled by good ol' Azure Load Balancer. Answer should be A in my opinion.

I want to give my humble opinion and emphasize that the answer is correct.

emphasis is on emphasis

same as az--303

From https://docs.microsoft.com/en-us/azure/application-gateway/how-application-gateway-works: > The health of the server is determined by a health probe. If the backend pool contains multiple servers, the application gateway uses a round-robin algorithm to route the requests between healthy servers. This load balances the requests on the servers.

As we all know, we can't emphasize enough. So let me emphasize as well that the provided answer is correct.

Right ans. Azure LB doesn't supports SSL offloading but App GW does.
