Question

Difficulty: EasyHigh Availability, Scalability, and Elasticity

A company is deploying an application in Azure. The company needs to ensure that the application remains accessible even during localized hardware failures, and that it can automatically scale resources up and down to match fluctuating daily demand. Which two cloud benefits directly address these requirements? (Select two)

  1. High availabilityAnswer
  2. ElasticityAnswer
  3. C
    Disaster recovery
  4. D
    Capital expenditure (CapEx)

Answer

High availability and Elasticity
High availability is correct because it ensures service uptime by providing redundancy to handle localized component failures. Elasticity is correct because it allows resources to scale out or in dynamically in response to changing demand.

Step-by-Step Solution

1
Analyze the requirement for continuous application accessibility during localized hardware failures.
Identify that High Availability is the cloud benefit designed to maximize service uptime and tolerate local component failures.
High availability ensures redundant systems are in place within a region to keep the application accessible.
2
Analyze the requirement to automatically adjust resources based on daily demand fluctuations.
Identify that Elasticity represents the ability to dynamically scale resources in and out automatically to match user load.
Elasticity allows systems to allocate more resources during peak times and deallocate them when demand drops, preventing unnecessary costs.
