A technician is trying to delete six decommissioned VMs. Four VMs were deleted without issue. However, two of the VMs cannot be deleted due to an error. Which of the following would MOST likely enable the technician to delete the VMs?
- A. Remove the VMs from the resource group
- B. Remove the lock from the two VMs
- C. Remove the snapshots
- D. Remove the VMs' IP addresses
Answer: B
Explanation:
Explanation
Removing the lock from the two VMs is what would most likely enable the technician to delete the VMs that cannot be deleted due to an error. A lock is a feature that prevents certain actions or operations from being performed on a resource or service, such as deleting, modifying, moving, etc. A lock can help to protect a resource or service from accidental or unwanted changes or removals. Removing the lock from the two VMs can enable the technician to delete them by allowing the delete action or operation to be performed on them.
NEW QUESTION # 190
A cloud engineer recently used a deployment script template to implement changes on a cloud-hosted web application. The web application communicates with a managed database on the back end. The engineer later notices the web application is no longer receiving data from the managed database. Which of the following is the MOST likely cause of the issue?
- A. Misconfiguration in the user permissions
- B. Misconfiguration in the network ACL
- C. Misconfiguration in the firewall
- D. Misconfiguration in the routing traffic
Answer: B
Explanation:
Explanation
The most likely cause of the issue is C. Misconfiguration in the network ACL. A network ACL (access control list) is a set of rules that controls the inbound and outbound traffic for a subnet or a virtual network in a cloud environment. A misconfiguration in the network ACL can block the communication between the web application and the managed database, resulting in data loss or unavailability. For example, according to the Azure SQL Database documentation1, if you use a virtual network service endpoint to secure your database, you need to configure the network ACL to allow traffic from the web application subnet to the database subnet. Otherwise, the web application will not be able to connect to the database. Similarly, according to the DigitalOcean tutorial2, if you use a managed database cluster, you need to add the web application's IP address or Droplet to the cluster's trusted sources list. Otherwise, the web application will not be able to access the database.
A misconfiguration in the user permissions, the routing traffic, or the firewall can also cause connectivity issues between the web application and the managed database, but they are less likely than a misconfiguration in the network ACL. A misconfiguration in the user permissions can prevent the web application from authenticating or authorizing with the database, but it will not affect the data transmission. A misconfiguration in the routing traffic can cause packets to be lost or delayed, but it will not block the communication entirely.
A misconfiguration in the firewall can filter out unwanted traffic, but it will not affect the traffic that is allowed by the network ACL. Therefore, these are not the most likely causes of the issue. For more information on how to troubleshoot connectivity issues between a cloud-hosted web application and a managed database, you can refer to the AWS documentation3 or the Google Cloud documentation.
NEW QUESTION # 191
A systems administrator is attempting to gather information about services and resource utilization on VMS in a cloud environment. Which of the following will BEST accomplish this objective?
- A. Syslog
- B. CMDB
- C. Performance monitoring
- D. Service management
- E. SNMP
Answer: C
Explanation:
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 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.
NEW QUESTION # 192
A systems administrator is diagnosing performance issues on a web application. The web application sends thousands of extremely complex SQL queries to a database server, which has trouble retrieving the information in time. The administrator checks the database server and notes the following resource utilization:
CPU: 64%
RAM: 97%
Network throughput: 384,100Kbps.
Disk throughput: 382,700Kbps
The administrator also looks at the storage for the database server and notices it is consistently near its OPS limit. Which of the following will BEST resolve these performance issues?
- A. Increase CPU resources on the database server.
- B. Put the storage and the database on the same VLAN.
- C. Enable deduplication on the storage appliance.
- D. Increase caching on the database server.
- E. Enable compression on storage traffic.
Answer: D
Explanation:
The performance issue is caused by the high demand of complex SQL queries on the database server, which consumes a lot of RAM and disk throughput. Increasing caching on the database server would reduce the number of disk reads and writes, as well as improve the response time of the queries by storing frequently accessed data in memory. This would be the best solution to resolve the performance issue.

NEW QUESTION # 193
A company that performs passive vulnerability scanning at its transit VPC has detected a vulnerability related to outdated web-server software on one of its public subnets. Which of the following can the use to verify if this is a true positive with the LEAST effort and cost? (Select TWO).
- A. Unknown environment penetration testing
- B. An agent-based scan
- C. A port scan
- D. A network-based scan
- E. A blue-team exercise
- F. A credentialed scan
- G. A red-team exercise
Answer: B,F
Explanation:
Explanation
The correct answer is B and E. An agent-based scan and a credentialed scan can help verify if the vulnerability related to outdated web-server software is a true positive with the least effort and cost.
An agent-based scan is a type of vulnerability scan that uses software agents installed on the target systems to collect and report data on vulnerabilities. This method can provide more accurate and detailed results than a network-based scan, which relies on network traffic analysis and probes1. An agent-based scan can also reduce the network bandwidth and performance impact of scanning, as well as avoid triggering false alarms from intrusion detection systems2.
A credentialed scan is a type of vulnerability scan that uses valid login credentials to access the target systems and perform a more thorough and comprehensive assessment of their configuration, patch level, and vulnerabilities. A credentialed scan can identify vulnerabilities that are not visible or exploitable from the network level, such as missing updates, weak passwords, or misconfigured services3. A credentialed scan can also reduce the risk of false positives and false negatives, as well as avoid causing damage or disruption to the target systems3.
A network-based scan, a port scan, a red-team exercise, a blue-team exercise, and unknown environment penetration testing are not the best options to verify if the vulnerability is a true positive with the least effort and cost. A network-based scan and a port scan may not be able to detect the vulnerability if it is not exposed or exploitable from the network level. A red-team exercise, a blue-team exercise, and unknown environment penetration testing are more complex, time-consuming, and costly methods that involve simulating real-world attacks or defending against them. These methods are more suitable for testing the overall security posture and resilience of an organization, rather than verifying a specific vulnerability4.

NEW QUESTION # 198
A cloud administrator is reviewing the annual contracts for all hosted solutions. Upon review of the contract for the hosted mail solution, the administrator notes the monthly subscription rate has increased every year. The provider has been in place for ten years, and there is a large amount of data being hosted. Which of the following is a barrier to switching providers?
- A. Service_level agreement
- B. Encrypted data
- C. Memorandum of understanding
- D. Vendor lock-in
Answer: D
Explanation:
The correct answer is B. Vendor lock-in. Vendor lock-in is a situation where a customer becomes dependent on a certain cloud provider and cannot easily switch to another provider without significant costs or disruptions. This can happen when the customer uses features or services that are only available from that specific provider, or when the customer has a large amount of data stored with the provider that is difficult to migrate. According to the web search results, vendor lock-in is a common concern in cloud computing1234. A service level agreement, a memorandum of understanding, and encrypted data are not barriers to switching providers, as they do not create a dependency on a specific provider or make it difficult to move data. For more information on vendor lock-in and how to avoid it, you can refer to the Cloudflare website1 or the Seagate blog4.

NEW QUESTION # 203
A new development team requires workstations hosted in a PaaS to develop a new website. Members of the team also require remote access to the workstations using their corporate email addresses. Which of the following solutions will BEST meet these requirements? (Select TWO).
- A. Create a new directory service.
- B. Migrate local VHD workstations.
- C. Implement a VDI solution.
- D. Configure email account replication.
- E. Deploy new virtual machines.
- F. Integrate identity services.
Answer: E,F
Explanation:
Explanation
A Platform-as-a-Service (PaaS) is a cloud computing model that provides customers a complete cloud platform-hardware, software, and infrastructure-for developing, running, and managing applications without the cost, complexity, and inflexibility that often comes with building and maintaining that platform on-premises1.
To develop a new website using a PaaS, the development team needs to deploy new virtual machines (VMs) on the cloud platform. VMs are software emulations of physical computers that can run different operating systems and applications. By deploying new VMs, the development team can create a scalable and flexible environment for their website project, without having to invest in or manage physical hardware2.
To enable remote access to the workstations using their corporate email addresses, the development team needs to integrate identity services on the cloud platform. Identity services are services that provide authentication, authorization, and identity management for users and devices accessing cloud resources. By integrating identity services, the development team can use their corporate email addresses as single sign-on (SSO) credentials to access their workstations from any device and location, while ensuring security and compliance3.
The other options are not the best solutions for these requirements:
Configuring email account replication is not necessary for remote access to the workstations. Email account replication is a process of synchronizing email accounts across different servers or locations. It can provide backup and redundancy for email services, but it does not provide authentication or identity management for remote access4.
Implementing a Virtual Desktop Infrastructure (VDI) solution is not a PaaS solution. VDI is a technology that allows users to access virtual desktops hosted on a centralized server. VDI can provide remote access to desktop environments, but it requires additional hardware, software, and management costs that are not included in a PaaS model5.
Migrating local VHD workstations is not a PaaS solution. VHD stands for Virtual Hard Disk, which is a file format that represents a virtual hard disk drive. Migrating local VHD workstations means moving the virtual hard disk files from local storage to cloud storage. This can provide backup and portability for the workstations, but it does not provide a complete cloud platform for developing and running applications6.
Creating a new directory service is not necessary for remote access to the workstations. A directory service is a service that stores and organizes information about users, devices, and resources on a network. Creating a new directory service means setting up a new database and schema for storing this information. This can provide identity management and access control for the network, but it does not provide authentication or SSO for remote access.
NEW QUESTION # 204
A VDI administrator has received reports from the drafting department that rendering is slower than normal. Which of the following should the administrator check FIRST to optimize the performance of the VDI infrastructure?
- A. CPU
- B. GPU
- C. Memory
- D. Storage
Answer: B
Explanation:
Checking the GPU (Graphics Processing Unit) is the first thing that the VDI administrator should do to optimize the performance of the VDI infrastructure for rendering tasks. GPU is a specialized hardware device that accelerates graphics processing and rendering. GPU can improve the user experience and performance of VDI applications that require intensive graphics processing, such as drafting, gaming, video editing, etc.
NEW QUESTION # 205
A systems administrator is deploying a solution that includes multiple network I/O-intensive VMs. The solution design requires that vNICs of the VMs provide low-latency, near-native performance of a physical NIC and data protection between the VMs. Which of the following would BEST satisfy these requirements?

NEW QUESTION # 208
A systems administrator recently deployed a VDI solution in a cloud environment; however, users are now experiencing poor rendering performance when trying to display 3-D content on their virtual desktops, especially at peak times.
Which of the following actions will MOST likely solve this issue?
- A. Update the quest graphics drivers from the official repository
- B. Instruct users to access virtual workstations only on the VLAN
- C. Add more vGPU licenses to the host
- D. Select vGPU profiles with higher video RAM
Answer: D
Explanation:
Explanation
A vGPU profile is a configuration option that defines the amount of video RAM (vRAM) and other resources that are allocated to a virtual machine (VM) that uses a virtual graphics processing unit (vGPU). A vGPU profile can affect the rendering performance of a VM, as it determines how much graphics memory and processing power are available for displaying complex graphics content. Selecting vGPU profiles with higher video RAM can most likely solve the issue of poor rendering performance when trying to display 3-D content on virtual desktops, especially at peak times, as it can provide more graphics resources and improve the quality and speed of rendering. References: CompTIA Cloud+ Certification Exam Objectives, page 11, section 1.6
NEW QUESTION # 209
A systems administrator has received an email from the virtualized environment's alarms indicating the memory was reaching full utilization. When logging in, the administrator notices that one out of a five-host cluster has a utilization of 500GB out of 512GB of RAM. The baseline utilization has been 300GB for that host. Which of the following should the administrator check NEXT?
- A. Storage array
- B. Running applications
- C. VM integrity
- D. Allocated guest resources
Answer: D
Explanation:
Explanation
Allocated guest resources is what the administrator should check next after receiving an email from the virtualized environment's alarms indicating the memory was reaching full utilization and noticing that one out of a five-host cluster has a utilization of 500GB out of 512GB of RAM. Allocated guest resources are the amount of resources or capacity that are assigned or reserved for each guest system or device within a host system or device. Allocated guest resources can affect performance and utilization of host system or device by determining how much resources or capacity are available or used by each guest system or device. Allocated guest resources should be checked next by comparing them with the actual usage or demand of each guest system or device, as well as identifying any overallocation or underallocation of resources that may cause inefficiency or wastage.

- A. LTS
- B. Stable
- C. Beta
- D. Canary
Answer: A
Explanation:
LTS (Long Term Support) is the update branch that the administrator should choose to ensure the system receives updates that are maintained for at least four years. An update branch is a category or group of updates that have different characteristics or features, such as frequency, stability, duration, etc. An update branch can help customers to choose the type of updates that suit their needs and preferences. LTS is an update branch that provides updates that are stable, reliable, and secure, and are supported for a long period of time, usually four years or more. LTS can help customers who value stability and security over new features or functions, and who do not want to change or upgrade their systems frequently.

- A. Add more memory to the web server
- B. Spin up a new database server
- C. Spin up a new web server
- D. Spin up a new application server
Answer: B
Explanation:
Explanation
Spinning up a new web server is what the administrator should perform first to speed up the response of the e-commerce platform that is hosted in a public cloud and starts to experience a slow response after announcing a big sales promotion. A web server is a system or service that hosts and delivers web content, such as web pages, images, videos, etc., to clients over a network or internet connection. A web server can affect the response of an e-commerce platform by determining how fast it can process and serve web requests or responses from clients. Spinning up a new web server can speed up the response of an e-commerce platform by providing benefits such as:
Scalability: Spinning up a new web server can increase the scalability of the e-commerce platform by adding more capacity or resources to handle the increased demand or load caused by the sales promotion, without affecting the existing web servers.
Performance: Spinning up a new web server can improve the performance of the e-commerce platform by reducing the latency or overhead of processing and serving web requests or responses from clients, which may cause delays or errors.
