CTO Cloud Strategy & Architecture 4

Question 1

A CTO is evaluating whether to use a public cloud, private cloud, or hybrid cloud for a defense contractor. What is the primary determinant?

Accepted Answer

Data classification requirements and government compliance mandates (e.g., FedRAMP, IL4/IL5)

Answer

Defense contractors must comply with government data classification standards like FedRAMP or Impact Level requirements, which dictate permissible cloud environments.

Question 2

What is the purpose of a Landing Zone in an enterprise cloud adoption?

Accepted Answer

A pre-configured, secure, multi-account cloud environment baseline that enforces governance from day one

Answer

A Landing Zone is a pre-built, governed multi-account environment that enforces security, networking, and compliance baselines before any workloads are deployed.

Question 3

Which cloud networking architecture pattern is best suited for connecting hundreds of VPCs across multiple AWS accounts while minimizing complexity?

Accepted Answer

Transit Gateway acting as a central hub

Answer

AWS Transit Gateway serves as a centralized hub that simplifies connectivity, replacing the O(n²) complexity of VPC peering meshes with a hub-and-spoke topology.

Question 4

A startup CTO is building a globally distributed application expecting users in 30 countries. Which database architecture best supports low-latency reads globally?

Accepted Answer

Multi-region active-active distributed database with local read replicas

Answer

Multi-region active-active distributed databases (like CockroachDB, Spanner, or DynamoDB Global Tables) provide low-latency reads and writes in each region with automatic replication.

Question 5

What is the correct definition of RTO and RPO in the context of cloud disaster recovery planning?

Accepted Answer

RTO = maximum downtime acceptable; RPO = maximum data loss acceptable

Answer

RTO (Recovery Time Objective) defines the maximum acceptable downtime after a disaster, while RPO (Recovery Point Objective) defines the maximum acceptable data loss measured in time.
