Total control over hardware

Answer

Guaranteed data privacy

Answer

No internet connectivity needed

Question 4

Which THREE components are typically included in the cloud provider's 'Shared Responsibility Model' as the CUSTOMER'S responsibility?

Accepted Answer

Identity and access management (IAM) policies. The customer is responsible for everything they put 'in' the cloud, including data, apps, and OS configurations.

Answer

Global network physical cabling

Answer

Physical data center security

Question 5

Which TWO factors contribute to the risk of 'Vendor Lock-in'?

Accepted Answer

Usage of proprietary APIs. Proprietary APIs and tightly coupled data formats prevent easy migration.

Answer

Using standard HTTP protocols

Answer

Using open-source software

Answer

Hiring many employees

Question 6

What does 'Multi-tenancy' in a public cloud mean?

Accepted Answer

Multiple customers, shared hardware. Multiple customers share the same underlying hardware resources.

Answer

One customer, multiple regions

Answer

Multiple clouds, one company

Answer

Multiple applications, one customer

Question 7

Which THREE factors must be considered when estimating cloud costs?

Accepted Answer

Resource type (instance size). Usage, region, and resource type are primary cost drivers.

Answer

Data center color

Answer

Number of end users

Question 8

Which THREE risks are associated with a 'Lift and Shift' (re-hosting) migration strategy?

Accepted Answer

Lower performance than on-premises. Lifting and shifting fails to take advantage of cloud-native benefits and often results in higher costs.

Answer

Lower security

Answer

Increased hardware maintenance

Question 9

A security auditor requests a solution to ensure that all data stored in the cloud is encrypted at rest. What should the administrator implement?

Accepted Answer

Server-side encryption. Server-side encryption ensures data is encrypted before being stored on disk.

Answer

VPC Security Groups

Answer

SSL/TLS

Answer

Multi-factor authentication

Question 10

A company requires a highly available database that replicates data synchronously across availability zones. Which setting should be chosen?

Accepted Answer

Multi-AZ deployment. Multi-AZ deployment ensures synchronous replication for high availability.

Answer

Auto Scaling

Answer

Read replica

Answer

Database snapshot

Question 11

Which THREE factors should a cloud architect consider when designing for high availability?

Accepted Answer

Multi-region deployment. High availability requires redundancy at multiple layers, geographical distribution, and automated failure detection.

Answer

Centralizing all resources in a single region

Answer

Fixed-capacity hardware provisioning

Question 12

Which THREE of the following tools or methods are used to secure data in transit in the cloud?

Accepted Answer

TLS 1.2/1.3. Data in transit is secured using encryption protocols (TLS/SSL) and private networking methods (VPN/Direct Connect).

Answer

Server-side encryption at rest

Answer

User access logs

Question 13

When evaluating a cloud service provider (CSP), which TWO of the following business-focused documentation should be requested to verify the vendor's reliability and security posture?

Accepted Answer

SOC 2 Type II reports. To assess risk and reliability, organizations must review the CSP's audit reports (like SOC2) and their documented Service Level Agreements.

Answer

The provider's quarterly stock earnings report

Answer

Employee payroll records

Answer

Internal office floor plans

Question 14

What is the purpose of a VPC Endpoint?

Accepted Answer

To access cloud services privately. It allows private communication between a VPC and cloud services, avoiding the public internet.

Answer

To connect two VPCs

Answer

To encrypt data transit

Answer

To provide public access

Question 15

Your organization is reviewing the shared responsibility model. Which TWO of the following are typically the responsibility of the cloud service provider?

Accepted Answer

Maintenance of the host virtualization layer. The provider is responsible for the underlying infrastructure (physical hardware and data center security).

Answer

Configuration of customer firewall rules

Answer

Management of customer guest OS

Answer

User access management

Question 16

Which TWO of the following are essential components of a Cloud Security Policy?

Accepted Answer

Data classification scheme. Security policies must define both authorized access and the classification of data being protected.

Answer

Cloud provider marketing strategy

Answer

Hardware procurement schedule

Answer

Network cable standards
