HAC Cloud Computing & Services 2 — Questions and Answers
Question 1: Which cloud deployment model hosts infrastructure exclusively for a single organization and can be managed on-premises or by a third party?
- Public cloud
- Hybrid cloud
- Private cloud (Correct answer)
- Community cloud
Correct answer: Private cloud
A private cloud is dedicated to one organization and offers greater control and security than public cloud models.
Question 2: In the context of HubSpot's cloud infrastructure, what does 'multi-tenancy' mean?
- Each customer gets a dedicated server instance
- Multiple customers share the same underlying infrastructure while data remains isolated (Correct answer)
- HubSpot stores data in multiple geographic regions simultaneously
- Admins can manage multiple portals from one login
Correct answer: Multiple customers share the same underlying infrastructure while data remains isolated
Multi-tenancy means multiple customers share cloud infrastructure, but HubSpot logically isolates each customer's data for security and privacy.
Question 3: What cloud service model provides virtualized computing resources such as servers, storage, and networking over the internet?
- SaaS
- PaaS
- IaaS (Correct answer)
- FaaS
Correct answer: IaaS
Infrastructure as a Service (IaaS) delivers virtualized hardware resources that customers can provision and manage without owning physical equipment.
Question 4: A HubSpot administrator notices portal data is syncing slowly during peak business hours. Which cloud concept best explains potential resource contention in a shared environment?
- Elasticity
- The noisy neighbor effect (Correct answer)
- Data sovereignty
- Cold storage tiering
Correct answer: The noisy neighbor effect
The noisy neighbor effect occurs when one tenant's heavy resource usage on shared infrastructure degrades performance for other tenants.
Question 5: What is the primary advantage of cloud elasticity for a HubSpot portal experiencing seasonal traffic spikes?
- Data is permanently replicated across all regions
- Resources automatically scale up or down to match demand without manual intervention (Correct answer)
- API rate limits are removed during peak periods
- All portal features are unlocked temporarily
Correct answer: Resources automatically scale up or down to match demand without manual intervention
Cloud elasticity allows infrastructure to dynamically scale resources in response to demand, ensuring performance during spikes without over-provisioning.
Question 6: Which term describes the ability of a cloud provider to guarantee a specific percentage of uptime over a given period, as stated in a formal agreement?
- RPO (Recovery Point Objective)
- SLA (Service Level Agreement) (Correct answer)
- MTD (Maximum Tolerable Downtime)
- QoS (Quality of Service) tier
Correct answer: SLA (Service Level Agreement)
A Service Level Agreement (SLA) formally commits the cloud provider to a defined uptime percentage and outlines remedies if that target is missed.
Question 7: When HubSpot stores contact data for EU customers under GDPR requirements, which cloud concept governs where that data must physically reside?
- Data portability
- Data sovereignty (Correct answer)
- Data deduplication
- Data federation
Correct answer: Data sovereignty
Data sovereignty refers to legal requirements that data must be stored and processed within specific geographic or political boundaries.
