- E. 10.168.0.64/26 and 10.168.0.64
Answer: C
Explanation:
Explanation
The IP address range 10.168.0.0/24 can be divided into four equal subnets of 64 addresses each by using a /26 mask. The subnets are 10.168.0.0/26, 10.168.0.64/26, 10.168.0.128/26, and 10.168.0.192/26. The last address in each subnet is the broadcast address, and the second-last address can be used as the gateway address for that subnet. Therefore, one of the possible subnets and firewall IPs for one of the environments is 10.168.0.0/26 and 10.168.0.63.

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. Enable deduplication on the storage appliance.
- C. Increase caching on the database server.
- D. Enable compression on storage traffic.
- E. Put the storage and the database on the same VLAN.
Answer: C
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 # 38
A company wants to utilize its private cloud for a new application. The private cloud resources can meet 75% of the application's resource requirements. Which of the following scaling techniques can the cloud administrator implement to accommodate 100% of the application's requirements?
- A. Cloud bursting
- B. Vertical
- C. Autoscaling
- D. Horizontal
Answer: A
Explanation:
According to the CompTIA Cloud+ Study Guide1, scaling is "the ability to increase or decrease the size or capacity of a cloud service". There are two main types of scaling: horizontal and vertical.
Horizontal scaling is "the ability to increase or decrease the number of instances or nodes of a cloud service". This means that horizontal scaling can add or remove servers or virtual machines to a cloud service, depending on the workload demand. Horizontal scaling can improve availability, reliability, and performance, but it can also increase complexity and cost.
Vertical scaling is "the ability to increase or decrease the resources allocated to an instance or node of a cloud service". This means that vertical scaling can add or remove CPU, memory, disk, or network resources to a server or virtual machine, depending on the workload demand. Vertical scaling can improve performance and efficiency, but it can also have limitations and risks.
Cloud bursting is "a technique that allows a private cloud to use public cloud resources when it reaches its capacity limit". This means that cloud bursting can extend the private cloud to the public cloud when there is a peak in demand that exceeds the private cloud resources. Cloud bursting can provide scalability, flexibility, and cost savings, but it can also introduce challenges such as security, compatibility, and latency.
Autoscaling is "the ability to automatically increase or decrease the number of resources allocated to a cloud service based on the current demand". This means that autoscaling can adjust the size or capacity of a cloud service without human intervention, using predefined rules or policies. Autoscaling can optimize performance, availability, and cost, but it can also require careful monitoring and configuration.
Based on this information, I think the best answer to your question is C.
Cloud bursting. Cloud bursting can help the company utilize its private cloud for the new application and also access public cloud resources when the private cloud resources can only meet 75% of the application's requirements. This way, the company can accommodate 100% of the application's requirements without having to purchase extra computing resources for their private cloud.
I hope this helps you understand the concept of cloud bursting better. If you want to learn more about CompTIA Cloud+, you can check out some of these resources:

NEW QUESTION # 39
A technician deployed a VM with NL-SAS storage to host a critical application. Two weeks later, users have begun to report high application latency. Which of the following is the BEST action to correct the latency issue?
- A. Increase the capacity of the data storage.
- B. Migrate the data to flash storage.
- C. Migrate the data to SAS storage.
- D. Increase the CPU of the VM.
Answer: B
Explanation:
Explanation
The correct answer is D. Migrate the data to flash storage. Flash storage is a type of solid-state storage that uses flash memory to store data. Flash storage has much faster performance and lower latency than NL-SAS storage, which is a type of hard disk drive that uses nearline serial attached SCSI interface. According to the web search results, NL-SAS devices have much higher response times than flash devices123. Therefore, migrating the data to flash storage can reduce the application latency and improve the user experience.
Increasing the capacity of the data storage, migrating the data to SAS storage, or increasing the CPU of the VM are not likely to solve the latency issue, as they do not address the root cause of the problem, which is the slow performance of NL-SAS storage. For more information on flash storage and its benefits, you can refer to the Dell EMC Unity: FAST Technology Overview2 or the Dell Technologies website4.

- A. Point-to-site
- B. Site-to-site
- C. Client-to-site
- D. Point-to-point
Answer: B
Explanation:
Explanation
A site-to-site VPN is a type of VPN configuration that establishes a secure connection between two networks, such as a data center and a cloud environment. A site-to-site VPN allows all the devices in one network to communicate with all the devices in the other network, without requiring individual VPN clients or connections. A site-to-site VPN is suitable for a company that is migrating workloads from on premises to the cloud and would like to establish a connection between the entire data center and the cloud environment, as it can provide seamless and secure access to both networks.

NEW QUESTION # 42
A cloud administrator is switching hosting companies and using the same script that was previously used to deploy VMs in the new cloud. The script is returning errors that the command was not found.
Which of the following is the MOST likely cause of the script failure?
- A. IP address changes
- B. Server name changes
- C. Account mismatches
- D. API version incompatibility
Answer: D
Explanation:
An application programming interface (API) is a set of rules or protocols that defines how different systems or applications can communicate or interact with each other. An API version is a specific iteration or release of an API that may have different features or functionalities than previous or subsequent versions. API version incompatibility is the most likely cause of the script failure when switching hosting companies and using the same script that was previously used to deploy VMs in the new cloud, as it can result in errors or failures when trying to execute commands or functions that are not supported or recognized by the new cloud provider's API version. The issue can be resolved by updating or modifying the script to match the new cloud provider's API version. Reference: CompTIA Cloud+ Certification Exam Objectives, page 13, section 2.5
