A systems administrator wants to ensure a system can adjust its resources based on usage. Which of the following will best accomplish this goal?
A. Anti-affinity B. Autoscaling C. Right-sizing D. Oversubscription
B. Autoscaling
Explanation
Autoscaling is the best option to accomplish the goal of adjusting system resources based on usage. Autoscaling automatically adjusts the number of compute resources (such as virtual machines or containers) based on predefined conditions or metrics, such as CPU utilization, memory usage, or incoming network traffic. When demand increases, autoscaling can dynamically add more resources to handle the load, and when demand decreases, it can remove unnecessary resources to optimize costs.
Question 243:
A company is concerned it will run out of VLANs on its private cloud platform in the next couple months, and the product currently offered to customers requires the company to allocate three dedicated, segmented tiers.
Which of the following can the company implement to continue adding new customers and to maintain the required level of isolation from other tenants?
A. GRE B. SR-IOV C. VXLAN D. IPSec
C. VXLAN
Explanation
One possible solution for the company to continue adding new customers and to maintain the required level of isolation from other tenants is to implement VXLAN. VXLAN is a network virtualization technology that can extend VLAN by adding a 24-bit segment ID, which allows up to 16 million unique virtual segments. VXLAN can encapsulate layer 2 Ethernet frames within layer 3 IP packets, and tunnel them across the underlying network. VXLAN can provide logical isolation and security for different tenants, as well as scalability and flexibility for large cloud computing environments1.
Question 244:
A company has deployed a new cloud solution and is required to meet security compliance.
Which of the following will MOST likely be executed in the cloud solution to meet security requirements?
A. Performance testing B. Regression testing C. Vulnerability testing D. Usability testing
C. Vulnerability testing
Explanation
Vulnerability testing is a type of security testing that identifies and evaluates the weaknesses or flaws in a system or service that could be exploited by attackers. Vulnerability testing can help meet security compliance requirements when deploying a new cloud solution, as it can reveal any potential security risks or gaps in the cloud environment and provide recommendations for remediation or mitigation. Vulnerability testing can also help improve security posture and performance, as it can prevent or reduce the impact of cyberattacks, data breaches, or service disruptions.
The performance of an e-commerce website decreases dramatically during random periods. The IT team is evaluating available resources to mitigate the situation.
Which of the following is the best approach to effectively manage this scenario?
A. Migrating to a dedicated host B. Purchasing additional servers C. Scheduling resource allocation D. Configuring automatic elasticity
D. Configuring automatic elasticity
Explanation
Configuring automatic elasticity is the best approach to manage an e- commerce website that experiences random performance drops due to variable traffic. Automatic elasticity enables the cloud resources to scale up or down automatically based on the current load, ensuring consistent performance even during unexpected traffic surges.
References: The concept of automatic elasticity is part of the cloud management and technical operations content in the CompTIA Cloud+ curriculum.
Question 246:
A bank informs an administrator that changes must be made to backups for long-term reporting purposes.
Which of the following is the most important change the administrator should make to satisfy these requirements?
A. Location of the backups B. Type of the backups C. Retention of the backups D. Schedule of the backups
C. Retention of the backups
Explanation
For long-term reporting purposes, the most critical aspect to consider is the retention period of the backups. This is because the bank will likely require access to historical data for audit, compliance, and reporting purposes. The retention policy will need to ensure that backups are kept for the required duration, which may be several years depending on regulatory and business needs. Adjusting the retention policy will help ensure that the necessary data is preserved for as long as it is needed, without unnecessary data accumulation that could lead to higher costs and management complexity.

Question 247:
The PMO wants to streamline the routing and approval of project activities in order to provide up-to-date visibility into project status. Which of the following collaboration tools would be most appropriate?
A. Real-time, multi-authoring tool B. Wiki knowledge base and search engine C. Workflow and e-signature platform D. File-sharing platform and storage system
C. Workflow and e-signature platform
Explanation
A workflow and e-signature platform automates approvals, routing, and visibility for project tasks. This ensures that documents and activities are approved efficiently and transparently, supporting operational efficiency. Real-time editing tools or file storage systems do not inherently provide workflow automation.

Question 248:
An organization's two-node, hybrid container cluster is experiencing failures during horizontal scaling to the cloud cluster instance. The on-premises IP range is 192.168.0.0/16, and the cloud environment is 10.168.0.0/16. Overlapping or stretched VLANs are not permitted, and a node is deployed in each location. The cloud monitoring agent reports a healthy status for the second instance, but when pinging the clusters from on premises, the following output is received:
Which of the following is the most likely reason for the scaling failure?
A. Incorrect DNS entry B. Offline cluster node C. Incorrect proxy entry D. Incorrect cluster IP E. Incorrect IP route
A. Incorrect DNS entry
Explanation
Question 249:
A company runs a discussion forum that caters to global users. The company's monitoring system reports that the home page suddenly is seeing elevated response times, even though internal monitoring has reported no issues or changes.
Which of the following is the most likely cause of this issue?
A. Cryptojacking B. Human error C. DDoS D. Phishing
C. DDoS
Explanation
Elevated response times without reported issues or changes internally could indicate a Distributed Denial of Service (DDoS) attack, where multiple systems flood the bandwidth or resources of a targeted system, usually one or more web servers.

Question 250:
Which of the following cloud deployment models is the best way to replicate a workload non-disruptively between on-premises servers and a public cloud?
A. Public B. Community C. Private D. Hybrid
D. Hybrid
Explanation
A hybrid cloud deployment model is the best way to replicate workloads non- disruptively between on-premises servers and a public cloud. This model integrates on- premises infrastructure, or private clouds with public clouds, allowing data and applications to be shared between them.
