Exam AZ-204 topic 2 question 1 discussion

Box 1: 4 There are four customers that use this service, and each instance of the WebJob processes data for a single customer and must run as a singleton instance. So, the number of VM should be 4. WebJobs is a feature of Azure App Service that enables you to run a program or script in the same instance as a web app. Like running background tasks. Box 2: Isolated Azure resources must be located in an isolated network . In the Isolated tier, the App Service Environment defines the number of isolated workers that run your apps, and each worker is charged. In addition, there's a flat Stamp Fee for the running the App Service Environment itself. Isolated: This tier runs dedicated Azure VMs on dedicated Azure Virtual Networks. It provides network isolation on top of compute isolation to your apps. It provides the maximum scale-out capabilities.

Got this in the exam yesterday.

WebJob Singleton instance implies that one VM can only run one service instance at a time across all VM instances, so we require 4 VM instances.

Number of VM instances: Since you have four customers, each with a separate instance of the WebJob that must run as a singleton instance, you need at least four instances of the App Service plan to ensure that each customer's WebJob runs independently. Therefore, you should configure the number of VM instances to be at least four. Pricing tier: Given the requirement for an isolated network and the need to minimize costs, the appropriate pricing tier for this scenario would be the "Isolated" tier. The Isolated tier provides dedicated infrastructure for your App Service Environment (ASE), ensuring isolation and security. While it may have higher costs compared to the Standard or Premium tiers, it offers the required level of isolation and network security for your scenario.

The singleton nature of the WebJobs does not necessitate a one-to-one mapping with VM instances, as singleton execution is managed by Azure and ensures that only one instance of a job runs across the entire App Service environment. so the required VMs are two(2) not four.

This was on the exam (July 2023). Went with proposed. Scored 917

Got this in the exam today ! Nov 25, 2022

Wrote exam yesterday, not even 60% question came from here :-(

Going with 4 VM's and Isolated.

the resource must be allocated as Isolate

Many questions are not from the dumps so prepare well before appearing for the exam. I passed with 720 score.

I passed the exam today with score 882.All the case studies and questions were the same with these samples in examtopics, except for two or three questions and one case study related to logic app. Good luck!

4/Isolated

yes the ans is correct
