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

Migrating the VM to a different host is a common technique to improve the performance of a VM that is suffering from resource contention or contention on the physical server. By moving the VM to a different host, the administrator can:

Reduce the stress and load on the original host, which may be under stress due to a peak usage workload.

Increase the availability and reliability of the VM, which may be experiencing slow performance due to resource contention or contention on the original host.

Balance the workload and resource utilization across multiple hosts, which may improve the overall performance and efficiency of the cloud environment.

Migrating the VM to a different host can be done manually or automatically, depending on the configuration and capabilities of the cloud platform. Some cloud platforms support live migration, which allows moving a VM to a different host without interrupting its operation or service. Other cloud platforms require shutting down or pausing the VM before migrating it to a different host .

The correct answer is B. Missing license.

Some hypervisor features may require a valid license to work properly. If the license is missing, expired, or invalid, the hypervisor may not be able to use those features or may operate in a reduced functionality mode. For example, some features of Hyper-V, such as live migration, replication, and failover clustering, require a license for Windows Server or Windows 10 Enterprise1. Similarly, some features of VMware ESXi, such as vMotion, Storage vMotion, and Fault Tolerance, require a license for VMware vSphere2.

Therefore, if a cloud administrator deployed new hosts in a private cloud and found that some of the hypervisor features did not seem to be working after a few months elapsed, the most likely cause was a missing license. The administrator should check the license status of the hypervisor and renew or activate the license if needed.

Incorrect permissions are not a likely cause of the issue, as they would affect the access to the hypervisor or its resources, not the functionality of the hypervisor itself. Incorrect tags are also not a likely cause of the issue, as they are used for identification and classification of resources, not for enabling or disabling features. Oversubscription is not a likely cause of the issue either, as it would affect the performance or availability of the resources, not the functionality of the hypervisor itself.

Performance monitoring is the process of collecting and analyzing metrics related to the performance and availability of resources in a cloud environment1. Performance monitoring can help a systems administrator to gather information about services and resource utilization on VMs in a cloud environment by providing the following benefits2:

Identify and troubleshoot performance issues and bottlenecks before they affect the end users or business operations.

Optimize the resource allocation and configuration to meet the performance requirements and SLAs of the services.

Plan for future capacity and scalability needs based on the historical trends and patterns of resource utilization.

Compare the performance and costs of different cloud service providers, regions, and SKUs.

Some of the tools and services that can help with performance monitoring in a cloud environment are3:

Azure Monitor: A comprehensive service that provides a unified view of the health, performance, and availability of your Azure resources, applications, and services. Azure Monitor collects metrics, logs, and traces from various sources and provides analysis, visualization, alerting, and automation capabilities.

Azure Advisor: A personalized service that provides recommendations to optimize your Azure resources for performance, security, cost, reliability, and operational excellence. Azure Advisor analyzes your resource configuration and usage data and suggests best practices to improve your cloud environment.

Azure Application Insights: A service that monitors the performance and usage of your web applications and services. Application Insights collects telemetry data such as requests, dependencies, exceptions, page views, custom events, and metrics from your application code and provides powerful analytics, diagnostics, and alerting features.

Azure Log Analytics: A service that collects and analyzes data from various sources such as Azure Monitor, Azure services, VMs, containers, applications, and other cloud or on-premises systems. Log Analytics enables you to query, visualize, and correlate log data using the Kusto Query Language (KQL) and create custom dashboards and reports.

Syslog is a standard protocol for sending log messages from network devices to a central server. Syslog can help with logging and auditing activities in a cloud environment, but it does not provide performance monitoring capabilities. Therefore, option A is incorrect.

SNMP (Simple Network Management Protocol) is a protocol for collecting and organizing information about managed devices on a network. SNMP can help with network management and monitoring in a cloud environment, but it does not provide comprehensive performance monitoring for VMs and services. Therefore, option B is incorrect.

CMDB (Configuration Management Database) is a database that stores information about the configuration items (CIs) in an IT environment. CMDB can help with configuration management and change management in a cloud environment, but it does not provide performance monitoring capabilities. Therefore, option C is incorrect.

Service management is a set of processes and practices that aim to deliver value to customers by providing quality services that meet their needs and expectations. Service management can help with service design, delivery, support, and improvement in a cloud environment, but it does not provide performance monitoring capabilities. Therefore, option D is incorrect.

When migrating an on-premises database to DBaaS, it is important to consider the database application version compatibility, the database IOPS values, and the database storage utilization. These factors can affect the performance, functionality, and cost of the migration. Database application version compatibility refers to the ability of the DBaaS provider to support the same or compatible version of the database software as the on-premises database. This can ensure that the database features, syntax, and behavior are consistent and compatible across the environments. Database IOPS values refer to the input/output operations per second that the database performs. This can indicate the workload and throughput of the database, and help determine the appropriate size and configuration of the DBaaS instance. Database storage utilization refers to the amount of disk space that the database consumes. This can affect the cost and scalability of the DBaaS service, and help optimize the storage allocation and backup strategies. References := CompTIA Cloud+ source documents or study guide

Answer: A. Chain of custody

A chain of custody is a document that records the sequence of custody, control, transfer, analysis, and disposition of physical or electronic evidence. A chain of custody is important to ensure the integrity and admissibility of evidence in legal cases. A cloud administrator who receives a physical disk that was analyzed by the incident response team should update the chain of custody to document when, how, and by whom the disk was handled, and what actions were performed on it12.

An incident taxonomy is a classification system that provides additional information about an incident, such as the nature, impact, intent, root cause, and data exposed. An incident taxonomy is useful for identifying trends and patterns, but it does not track the movement or manipulation of evidence3.

A risk register is a document that identifies, records, and assesses potential risks in a project or an organization. A risk register helps to prioritize and mitigate risks, and to develop contingency plans. A risk register is not directly related to the analysis of a physical disk by the incident response team4.

An incident playbook is a document that provides a series of prescriptive steps and guidance for responding and resolving incidents. An incident playbook helps to simplify and standardize the response process, and to reduce human error. An incident playbook does not record the details or outcomes of the response actions5.

B. USB devices and F. Printers are most likely to be allowed in the upgrade. USB devices are common peripherals that users may want to connect to their virtual workstations, such as flash drives, keyboards, mice, webcams, etc. Printers are also useful devices that users may need to print documents from their virtual desktops. VDI software can support USB redirection and printer redirection to enable these devices to work with virtual workstations12.

Display monitors, SATA devices, PCIe devices, and PCI devices are less likely to be allowed in the upgrade, as they are either part of the physical hardware of the end device or the server, or they require direct access to the host system. VDI software typically does not support these types of devices, as they are not compatible with the virtualization layer or the remote display protocol34.

An Intrusion Detection System (IDS) is a software or hardware system that monitors network traffic for malicious activity and alerts the administrator of any potential threats. An Intrusion Prevention System (IPS) is a software or hardware system that not only detects but also blocks or mitigates the malicious activity. Both IDS and IPS are essential for securing a web application in a cloud environment1.

A web proxy server is a server that acts as an intermediary between the client and the web server. It can provide caching, filtering, and authentication services, but it does not offer IDS/IPS functionality. Therefore, option A is incorrect.

Load balancing using SSI (Server Side Includes) is a technique that distributes the workload among multiple web servers by inserting dynamic content into web pages. It can improve the performance and availability of a web application, but it does not provide IDS/IPS protection. Therefore, option B is incorrect.

Implementing IDS/IPS agents on each instance running in that virtual private network is a valid solution for providing IPS protection for traffic coming from the internet. The agents can monitor and inspect the network traffic on each instance and block or report any suspicious activity to a central management console. This can prevent attacks from reaching the web application or spreading to other instances in the same network. Therefore, option C is correct.

Implementing dynamic routing is a technique that allows routers to select the best path for forwarding packets based on network conditions. It can enhance the reliability and efficiency of a network, but it does not offer IDS/IPS functionality. Therefore, option D is incorrect.

Hardened baselines are a set of security best practices that reduce the vulnerability of a system to exploits by reducing its attack surface1. They are also known as security configurations or benchmarks, and they provide a standard level of system hardening for an organization23.

Checking the hardened baselines of the servers is the first step that a cloud administrator should take to ensure compliance with the company’s security policy. This is because hardened baselines can help to:

Identify and eliminate common vulnerabilities and exposures (CVEs) that attackers can exploit1.

Remove unnecessary or unused services, accounts, software, and ports that can increase the attack surface23.

Apply appropriate settings and controls for encryption, authentication, authorization, firewall, and logging23.

Streamline audits and testing by reducing complexity and providing a reliable benchmark23.

Detailed Explanation:

C. Revoke the misconfigured permission policy: Reverting the incorrect policy ensures no further public access.

E. Change the affected credentials: If credentials were exposed, they must be updated to prevent unauthorized use.
