CV0-003 Exam Dumps - CompTIA Cloud+ Questions and Answers

The technology that provides the most portability for a multicloud environment is containers. Containers are units of software that package an application and its dependencies into a standardized and isolated environment that can run on any platform or cloud service. Containers are lightweight, scalable, and portable, as they do not depend on the underlying infrastructure or operating system. Containers can also be managed by orchestration tools that automate the deployment, scaling, and networking of containerized applications across multiple clouds.

CI/CD tools are software tools that enable continuous integration and continuous delivery or deployment, which are methods to frequently deliver software products to customers by introducing automation into the stages of software development. CI/CD tools can help a product-based company to transition to a method that provides the capability to enhance the product seamlessly and keep the development iterations to a shorter time frame, as they can offer the following benefits:

Faster and more reliable delivery of software products, as CI/CD tools can automate the processes of building, testing, and deploying code changes, reducing manual errors and delays.

Higher quality and performance of software products, as CI/CD tools can facilitate ongoing feedback, monitoring, and improvement of the code, ensuring that it meets the customer expectations and requirements.

Greater collaboration and communication among the development teams, as CI/CD tools can integrate with various tools and platforms, such as version control systems, code repositories, testing frameworks, and cloud services, enabling a seamless workflow and visibility across the software lifecycle.

Some examples of popular CI/CD tools are Jenkins1, CircleCI2, GitLab CI/CD3, and AWS CodeBuild4.

The best solution to resolve the issue of network slowness caused by high uplink bandwidth utilization on the core switch is to enable quality of service (QoS) to prioritize production traffic over other types of traffic. QoS is a mechanism that allows network administrators to classify and manage network traffic according to its importance, latency, bandwidth, and reliability requirements. By enabling QoS, the core switch can allocate more resources and guarantee better performance for production traffic, while limiting or dropping less critical traffic.

System hardening. System hardening is the process of securing a system by reducing its surface of vulnerability, which is larger when a system performs more functions. In contrast to system hardening, which is performed once, patch management, vulnerability scanning, and log monitoring are ongoing processes. By hardening the VDI instances, the provider can prevent users from installing prohibited software or making unauthorized changes to the system configuration. This can be done by applying security policies, disabling unnecessary services, removing default accounts, and enforcing strong passwords. For more information on system hardening, you can refer to the CompTIA Cloud+ CV0-003 Certification Study Guide1 or the CompTIA Cloud+ (Plus) Certification website2.

The chain of custody is a process that documents and preserves the integrity and authenticity of evidence from the time it is collected until it is presented in court. The chain of custody includes information such as who collected, handled, stored, or transferred the evidence, when and where it was done, and how it was done. By accidentally deleting the perpetrator’s user data, the security administrator has violated the chain of custody, as the evidence has been altered or destroyed and can no longer be used in court.

The best way to connect all the VPCs for the company that is planning its cloud architecture and wants to use a VPC for each of its three products per environment in two regions, totaling 18 VPCs, is to use a hub and spoke model. A hub and spoke model is a networking model that uses a central hub VPC that connects to multiple spoke VPCs that host the products or workloads. The hub VPC can provide common services and security policies for the spoke VPCs, such as network virtual appliances, DNS servers, firewalls, or VPN gateways. The spoke VPCs can communicate with each other through the hub VPC, using private IP addresses or peering connections. A hub and spoke model can simplify the management and scalability of the network, as well as reduce the costs and complexity of peering multiple VPCs directly.

Maximum resource consumption is what will help predict the operational expenditures in the cloud for an application that is being migrated from on premises to a public cloud provider. Operational expenditures are the ongoing costs of running and maintaining a system or service, such as cloud resources or services. Operational expenditures can vary depending on various factors, such as usage, demand, performance, etc. Maximum resource consumption is the highest amount of resources or capacity that are used or consumed by a system or service during peak periods of activity or load. Maximum resource consumption can help predict operational expenditures in the cloud by providing information such as:

Resource type: This indicates what type of resources are used or consumed by the system or service, such as compute, storage, network, etc.

Resource amount: This indicates how much of each resource type are used or consumed by the system or service, such as CPU cores, memory, disk space, bandwidth, etc.

Resource price: This indicates how much each resource type costs in the cloud provider’s pricing model, such as per hour, per GB, per Mbps, etc.

The fastest way to restore the service after deploying a new application release to the green stack of a blue-green infrastructure model and making the green stack primary is to failback to the blue stack. Failing back means switching back to the previous version of the application that is running on the blue stack, which is still available and functional. This will minimize the downtime and impact on the users, while allowing the systems administrator to troubleshoot and fix the issues on the green stack.

The best options to implement for a public cloud solution for an existing application using lift and shift that requires scalability and external access are a load balancer and a VPN (virtual private network). A load balancer is a device or service that distributes incoming traffic across multiple servers or instances based on various criteria, such as availability, capacity, or performance. A load balancer can improve scalability by balancing the workload and optimizing resource utilization. A VPN is a technology that creates a secure and encrypted connection over a public network, such as the internet. A VPN can provide external access by allowing remote users or sites to connect to the cloud resources as if they were on the same private network.
