Question 1

A company's content management system (CMS) service runs on an laaS 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?



Answer : A

To identify DDoS attacks against a CMS service, a cloud engineer should monitor network flow logs. These logs provide data about the IP traffic going to and from network interfaces in a public cloud, which is essential for detecting the increased traffic volumes typically associated with DDoS attacks.

Question 2

Which of the following is the most cost-effective and efficient strategy when migrating to the cloud?



Answer : A

The most cost-effective and efficient strategy when migrating to the cloud can often be to 'retire' or turn off legacy systems that are no longer useful or necessary. This avoids spending resources on migrating and maintaining systems that do not provide value in a cloud environment.

: Cloud migration strategies, including retiring outdated systems, are part of the decision-making process for cloud adoption in the CompTIA Cloud+ certification material.


Question 3

A cloud engineer has provisioned a VM for a high-frequency trading application. After the VM is put into production, users report high latency in trades. The engineer checks the last six hours of VM metrics and sees the following:

* CPU utilization is between 30% to 60%.

* Networkln is between 50Kbps and 70Kbps.

* NetworkOut is between 3.000Kpbs and 5.000Kbps.

* DiskReadOps is at 30.

* DiskWriteOps is at 70

* Memory utilization is between 50% and 70%.

Which of the following steps should the engineer take next to solve the latency issue?



Answer : A

Since the NetworkOut is significantly higher than NetworkIn and considering the nature of a high-frequency trading application, the issue most likely lies with network throughput. Moving to a network-optimized instance type would provide higher network bandwidth, which can reduce latency in trades.

: This solution is derived from the Management and Technical Operations domain of the CompTIA Cloud+ objectives, focusing on performance optimization for cloud services.


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.

: Data transfer and querying methods are part of the technical knowledge associated with cloud computing, as included in CompTIA Cloud+.


Question 5

A cloud administrator needs to collect process-level, memory-usage tracking for the virtual machines that are part of an autoscaling group. Which of the following is the best way to

accomplish the goal by using cloud-native monitoring services?



Answer : B

To collect process-level, memory-usage tracking for virtual machines, deploying cloud-monitoring agent software is the best approach. The agent can gather detailed system metrics and send them to the cloud-native monitoring services for analysis and visualization.

Question 6

Which of the following requirements are core considerations when migrating a small business's on-premises applications to the cloud? (Select two).



Answer : A, D

When migrating on-premises applications to the cloud for a small business, availability and networking are core considerations. Ensuring that applications are available and that the network is capable of handling the new cloud traffic are pivotal for a successful transition.

: The migration process and its core considerations, including availability and networking, are topics within the Business Principles of Cloud Environments in the CompTIA Cloud+ material.


Question 7

Which of the following interfaces is most commonly used for SSDs but not for HDDs?



Answer : A

NVMe (Non-Volatile Memory Express) is the interface most commonly associated with SSDs, especially in modern cloud and data center environments, because it was designed specifically to take advantage of flash storage performance. NVMe connects over PCIe, enabling far higher throughput and dramatically lower latency than legacy storage interfaces. It also supports deep parallelism through multiple queues, which aligns well with high IOPS workloads commonly seen in cloud deployments such as databases, virtualization, and high-transaction applications. In contrast, SATA and SAS were originally designed around traditional spinning disks and their command sets, and while SSDs can use SATA/SAS, those interfaces can become a bottleneck compared to NVMe. iSCSI is not a disk interface like NVMe; it is a network storage protocol used to transport SCSI commands over IP networks, and it can be used with both HDD- and SSD-backed storage arrays. From the Cloud+ CV0-004 perspective, selecting NVMe supports objectives related to performance optimization, storage architecture choices, and meeting workload latency requirements.
