Q1. A startup wants to launch a new web application without buying any physical servers, and wants to pay only for the compute it actually consumes each month. Which cloud characteristic does this describe?
A. High availability
B. Fault tolerance
C. Consumption-based pricing
D. Business continuity
Show answer & explanation
✓ Answer: C. Consumption-based pricing
Consumption-based (pay-as-you-go) pricing means customers pay only for the resources they use, with no large upfront capital outlay. High availability and fault tolerance describe resilience, not cost model. Business continuity is about surviving disruption, not billing.
Q2. Which statement correctly describes the relationship between Azure regions and availability zones?
A. Every Azure region contains at least three availability zones
B. Availability zones are physically separate locations within a region, each with independent power, cooling and networking
C. An availability zone is a single datacentre shared by all regions
D. Availability zones replace the need for region pairs
Show answer & explanation
✓ Answer: B. Availability zones are physically separate locations within a region, each with independent power, cooling and networking
Availability zones are physically separate facilities within the same region, each with independent power, cooling and networking, so a failure in one zone is unlikely to affect another. Not all regions have availability zones, so the first option is wrong.
Q3. A company wants to access an Azure PaaS service, such as a storage account, from within a virtual network using a private IP address instead of the service's public endpoint. Which feature should they implement?
A. Azure Private Link
B. Azure Bastion
C. Network Security Group
D. Azure ExpressRoute Direct
Show answer & explanation
✓ Answer: A. Azure Private Link
Azure Private Link provides private connectivity from a virtual network to Azure PaaS services over a private IP address, keeping traffic off the public internet entirely. Bastion is for secure VM management access, not for connecting to PaaS services.
