A cloud engineer is designing a cloud native, three-tier application. The engineer must adhere to the following security best practices:-Minimal services should run on all layers of the stack.-The solution should be vendor agnostic.-Virtualization could be used over physical hardware.Which of the following concepts should the engineer use to design the system to best meet these requirements?
Answer(s): B
Microservices architecture is ideal for building a three-tier application that adheres to security best practices by enabling each service to run independently with only the necessary components, thus adhering to the principle of minimal services on each layer. Microservices are also vendor-agnostic, meaning the application can be deployed across different cloud providers, meeting the requirement for a vendor-agnostic solution.
A cloud solutions architect needs to have consistency between production, staging, and development environments. Which of the following options will best achieve this goal?
Answer(s): A
Terraform templates with environment variables allow the architect to define infrastructure as code, ensuring that the production, staging, and development environments are consistently provisioned with the same configurations. By using environment variables, specific settings can be adjusted per environment without altering the core template, which supports consistency across environments.
A healthcare organization must follow strict compliance requirements to ensure that PII is not leaked. The cloud administrator needs to ensure the cloud email system can support this requirement. Which of the following should the organization enable?
DLP (Data Loss Prevention) is specifically designed to prevent sensitive data, such as Personally Identifiable Information (PII), from being leaked or improperly shared. In a cloud email system, DLP can monitor and control the flow of sensitive data to ensure compliance with strict regulatory requirements.
A company’s content management system (CMS) service runs on an IaaS cluster on a public cloud. The CMS service is frequently targeted by a malicious threat actor using DDoS.Which of the following should a cloud engineer monitor to identify attacks?
Network flow logs capture details about traffic flowing to and from instances in a cloud environment, including information such as IP addresses, ports, protocols, and packet counts. Monitoring network flow logs allows the cloud engineer to detect unusual traffic patterns or large volumes of requests, which are indicators of a DDoS attack.
Which of the following is the most cost-effective way to store data that is infrequently accessed?
Answer(s): C
Which of the following models will best reduce the cost of running short-term, non-critical workloads?
Spot instances are offered by cloud providers at a significantly reduced cost because they use spare capacity. These instances are ideal for short-term, non-critical workloads, as they can be terminated by the provider with little notice. This makes them highly cost-effective for workloads that can tolerate interruptions.
Which of the following vulnerability management concepts is best defined as the process of discovering vulnerabilities?
Which of the following types of storage provides the greatest performance advantage for a traditional relational database?
Block storage offers the highest performance for traditional relational databases because it provides low-latency, high-throughput access to data, making it ideal for database workloads that require fast and efficient read/write operations.
