CCP AWS Global Infrastructure 2 — Questions and Answers
Question 1: Why would a company choose to host resources in multiple AWS Availability Zones?
- To reduce the cost of their workloads
- To achieve high availability and fault tolerance (Correct answer)
- To comply with GDPR data residency requirements
- To access more instance types
Correct answer: To achieve high availability and fault tolerance
Deploying across multiple AZs ensures your application remains available even if one AZ experiences an outage, providing fault tolerance.
Question 2: What does AWS data sovereignty mean in the context of Regions?
- AWS owns all data stored in its cloud
- Your data does not leave a Region unless you explicitly move it (Correct answer)
- Data is replicated globally by default for redundancy
- Only AWS employees can access data in government regions
Correct answer: Your data does not leave a Region unless you explicitly move it
AWS guarantees that your data and services stay within the Region you choose unless you take explicit actions to replicate or transfer data elsewhere.
Question 3: What is the AWS Global Network?
- A public internet connection between AWS services
- A private, high-bandwidth, low-latency fiber network that connects AWS Regions and data centers (Correct answer)
- A VPN service for connecting on-premises networks to AWS
- A CDN for delivering static assets globally
Correct answer: A private, high-bandwidth, low-latency fiber network that connects AWS Regions and data centers
The AWS Global Network is a private, redundant fiber network connecting all AWS infrastructure, providing more reliable and faster inter-Region communication than the public internet.
Question 4: Which AWS service uses the global network to accelerate internet traffic for your application by routing it through the nearest AWS edge location?
- Amazon Route 53
- AWS Direct Connect
- AWS Global Accelerator (Correct answer)
- Amazon CloudFront
Correct answer: AWS Global Accelerator
AWS Global Accelerator routes user traffic through the AWS global network to the optimal endpoint, improving availability and performance.
Question 5: How many factors should you consider when choosing an AWS Region for your workload?
- Only cost
- Only latency
- Compliance, latency, service availability, and pricing (Correct answer)
- Only where AWS has the most capacity
Correct answer: Compliance, latency, service availability, and pricing
When selecting a Region, best practice is to evaluate four factors: data compliance/residency requirements, proximity to users, available services, and pricing.
Question 6: What is AWS Wavelength designed to support?
- Satellite-based internet connections
- Ultra-low latency applications for 5G mobile devices by embedding AWS compute within telecom networks (Correct answer)
- On-premises database migrations
- Cross-region disaster recovery
Correct answer: Ultra-low latency applications for 5G mobile devices by embedding AWS compute within telecom networks
AWS Wavelength embeds AWS compute and storage within 5G networks at the telecom edge, enabling single-digit millisecond latency for mobile applications.
