Question 1
Which of the following is a customer be responsible for in a provider-managed database service? (Select two).
Answer : B, E
In a provider-managed database service, the cloud provider typically manages the infrastructure, operating system, and database engine updates. However, the customer is responsible for the data and its security within the database, which includes setting table-level permissions and row-level encryption to ensure that data access and security is managed appropriately.

Question 2
A network administrator is budding a site-to-site VPN tunnel from the company's headquarters office 10 the company's public cloud development network. The network administrator confirms the following:
The VPN tunnel is established on the headquarter office firewall.
While inside the office, developers report that they cannot connect to the development network resources.
While outside the office on a client VPN, developers report that they can connect to the development network resources.
The office and the client VPN have different IP subnet ranges.
The firewall flow logs show VPN traffic is reaching the development network from the office.
Which of the following is the next step the next network administrator should take to troubleshoot the VPN tunnel?
Answer : A
The next step in troubleshooting the VPN tunnel issue is to review the development network routing table. This action will help determine if the routing configurations are correctly directing traffic from the headquarters office through the VPN tunnel to the development network resources. Proper routing ensures that data packets find their way to the correct destination within the cloud environment, which is critical for establishing successful communication between different network segments. Reference: CompTIA Cloud+ materials stress the importance of networking fundamentals in cloud environments, including VPN configurations and routing, to ensure secure and efficient connectivity between on-premises infrastructure and cloud resources.
Question 3
A cloud engineer is developing an operating expense report that will be used to purchase various cloud billing models for virtual machine instances. The cloud billing model must meet the following requirements:
* The instance cannot be ephemeral.
* The minimum life cycle of the instance is expected to be five years.
* The software license is charged per physical CPU count.
Which of the following models would best meet these requirements?
Answer : D
Reserved resources, or Reserved Instances, are ideal for workloads with predictable usage and a long-term commitment, such as a minimum lifecycle of five years. This model allows for significant cost savings compared to on-demand pricing, and the instance is not ephemeral, meaning it persists and is dedicated to the user for the duration of the reservation. The licensing charged per physical CPU count aligns with dedicated host or reserved instance models, but the long-term commitment points more towards reserved resources.
Question 4
A software engineer needs to transfer data over the internet using programmatic access while also being able to query the dat
a. Which of the following will best help the engineer to complete this task?
Answer : D
GraphQL is the best option for transferring data over the internet with programmatic access and querying capabilities. It is a query language for APIs and a runtime for executing those queries with existing data, providing a more efficient, powerful, and flexible alternative to the REST API. Reference: Data transfer and querying methods are part of the technical knowledge associated with cloud computing, as included in CompTIA Cloud+.
Question 5
Which of the following is used to deliver code quickly and efficiently across the development, test, and production environments?
Answer : B
A container image is used to deliver code quickly and efficiently across the development, test, and production environments. Container images are lightweight, standalone, executable software packages that include everything needed to run a piece of software, including the code, runtime, system tools, libraries, and settings.

Question 6
An administrator configures three subnets to the corporate network. All servers should communicate with the main corporate network and access the internet. The administrator creates the following configurations:
After configuring the networks, the administrator recognizes an issue with the configuration. Which of the following can the administrator change in one step to accomplish the goal?
Answer : B
A . Remove 192.168.12.0/24 and 192.168.1.0/24: This would cause connectivity issues for Network 4.
B . Replace 192.168.1.0/24 with 192.168.0.0/24: Corrects the incorrect destination for Network 4, aligning it with the corporate network subnet.
C . Add 192.168.12.0/24 and 192.168.0.0/24: Duplicates an existing configuration and doesn't solve the issue.
D . Reconfigure Network 4 to 192.168.13.0/24: Alters the network unnecessarily and doesn't resolve the destination routing issue.
CompTIA Cloud+ CV0-004 Study Guide, Objective 2.2: Configure routing tables to ensure proper network communication.
Question 7
A write-intensive workload is having frequent performance issues. The workload is running on pay-as-you-go VMs. These VMs use SSDs and have appropriate CPU and RAM sizes. The workload writes millions of small files and has a one-year retention requirement. Which of the following actions should be taken?
Answer : A
Comprehensive and Detailed Step-by-Step
A . Use provisioned IOPS volumes: Ideal for write-intensive workloads as they provide guaranteed performance by provisioning a specific number of IOPS.
B . Increase the VM size: CPU or RAM upgrades won't significantly benefit a storage-bound workload.
C . Switch to reserved VMs: Cost-effective but doesn't address performance issues.
D . Change to ephemeral storage: Temporary storage is not suitable for workloads requiring a one-year retention policy.
CompTIA Cloud+ CV0-004 Study Guide, Objective 3.2: Select appropriate storage types for specific workloads.
