A large e-commerce company is planning to host their applications on Microsoft Azure and is evaluating strategies to ensure high availability and fault tolerance. They are considering two approaches: using Availability Zones within a single Azure region or deploying across multiple Azure regions. Considering factors such as cost, compliance, scalability, and the ability to withstand region-wide outages, which of the following statements accurately describes the benefits and limitations of each approach? (Choose two options)
A
Availability Zones within a single region offer high availability and fault tolerance against most failures but do not protect against region-wide outages, making them a cost-effective solution for applications that can tolerate such risks.
B
Deploying across multiple Azure regions provides the highest level of fault tolerance, including protection against region-wide outages, but introduces higher costs, increased complexity, and potential latency issues.
C
Using Availability Zones is always the best choice for all applications because it guarantees 100% uptime and is the simplest to manage, regardless of the application's requirements or budget constraints.
D
The choice between using Availability Zones and multiple regions should be based solely on the company's current budget, without considering future scalability or compliance requirements.
E
Both Availability Zones and multiple regions have their place in a comprehensive high availability strategy; the optimal choice depends on the application's specific requirements, including tolerance for downtime, budget, and compliance needs.
