AZ-305 Question #314: Real Exam Question with Answer & Explanation

Question

Hotspot Question You are developing a multi-tier app named App1 that will be hosted on Azure virtual machines. The peak utilization periods for App1 will be from 8 AM to 9 AM and 4 PM to 5 PM on weekdays. You need to deploy the infrastructure for App1. The solution must meet the following requirements: - Support virtual machines deployed to four availability zones across two Azure regions. - Minimize costs by accumulating CPU credits during periods of low utilization. What is the minimum number of virtual networks you should deploy, and which virtual machine size should you use? To answer, select the appropriate options in the answer area. Answer:

Explanation

The correct answers are 2 virtual networks and a Bv2 (burstable) series VM size. Two virtual networks are required because the solution must span two Azure regions, and virtual networks are region-scoped resources - each region requires its own VNet, with the two VNets connected via Global VNet Peering to enable cross-region communication. The Bv2 (burstable) VM series is the correct choice because it is specifically designed to accumulate CPU credits during periods of low utilization and burst to higher performance during peak periods (8-9 AM and 4-5 PM), directly satisfying the cost-minimization requirement.
