NEW QUESTION # 229
A business analyst is reviewing the following CSP expenditures:
All instances run the same workloads, which vary at different times of the day. Which of the following describes how the company can reduce its spending?
- A. Convert the reserved instances to spot instances.
- B. Convert the spot instances to reserved instances.
- C. Release the reserved instances.
- D. Release the spot instances.
Answer: A
Explanation:
Since spot instances are more cost-effective compared to reserved instances, the company can convert some reserved instances to spot instances. Spot instances typically cost less, but they are subject to interruption, which might be acceptable for workloads with varying demand.
The best approach to reduce costs would be Convert the reserved instances to spot instances.
By doing this, the company can reduce its expenditure from $10,000 to $2,500 for the same workload, assuming the spot instances can handle the workload during peak times.

NEW QUESTION # 231
Which of the following security objectives is MOST improved when moving a system to the cloud?
- A. Integrity
- B. Availability
- C. Privacy
- D. Confidentiality
Answer: B
Explanation:
Availability is one of the security objectives that refers to the ability of authorized users to access and use the system and its resources when needed1. Availability is most improved when moving a system to the cloud, as cloud computing offers several benefits that enhance the reliability and accessibility of the system, such as23:
Scalability: Cloud computing allows the system to dynamically adjust the amount of resources allocated to meet the changing demand, without affecting the performance or availability of the system.
Redundancy: Cloud computing provides multiple copies of the system and its data across different locations and servers, ensuring that the system can continue to operate even if one or more components fail.
Backup and recovery: Cloud computing enables the system to regularly backup the data and configuration to the cloud, and restore them quickly in case of a disaster or a failure.
Maintenance and updates: Cloud computing allows the system to receive timely and automatic updates and patches from the cloud provider, without disrupting the availability of the system or requiring downtime.
Service level agreements: Cloud computing offers service level agreements (SLAs) that guarantee a certain level of availability and uptime for the system, and provide compensation or remediation in case of a breach.

NEW QUESTION # 234
An organization wants to migrate a locally hosted application to a PaaS model. The application currently runs
on a 15-year-old operating system and cannot be upgraded.
Which of the following should the organization perform to ensure the application will be supported in the cloud?
- A. Risk register
- B. Baseline
- C. Feasibility study
- D. Benchmarks

NEW QUESTION # 235
An organization has determined it is more cost efficient to move its internal applications to the cloud. In which of the following areas would the organization realize the most significant savings?
- A. Bandwidth costs
- B. Licensing costs
- C. Data center maintenance costs
- D. Human capital costs
- E. Compute costs
Answer: C
Explanation:
Moving internal applications to the cloud typically allows organizations to significantly reduce or eliminate data center maintenance costs, which include costs associated with hardware, power, cooling, physical security, and staff needed to maintain the infrastructure. By leveraging the cloud, these expenses are shifted to the cloud service provider, resulting in potential savings for the organization.
NEW QUESTION # 236

- A. Serviceability
- B. Availability
- C. Elasticity
- D. Scalability
Answer: B
NEW QUESTION # 237

NEW QUESTION # 238
Volume, variety, velocity, and veracity are the four characteristics of:
- A. machine learning.
- B. microservice design.
- C. Big Data.
- D. object storage.
- E. blockchain.
Answer: C
Explanation:
Big Data is a term that refers to data sets that are too large, complex, or diverse to be processed by traditional methods1. Big Data is characterized by four V's: volume, variety, velocity, and veracity2. Volume refers to the amount of data being generated and collected. Variety refers to the different types of data, such as structured, unstructured, or semi-structured. Velocity refers to the speed at which the data is created, processed, and analyzed. Veracity refers to the quality and reliability of the data.

NEW QUESTION # 239
Which of the following is a security advantage of using CDNs?
- A. Advanced threat inspection
- B. Data encryption at rest
- C. Resiliency against DDoS attacks
- D. VPN sessions to the consumers
Answer: C
Explanation:
A content delivery network (CDN) is a network of servers that deliver web content to users based on their geographic location. A CDN can improve the performance, reliability, and security of a web application by caching content closer to the users and reducing the load on the origin server. One of the security advantages of using a CDN is that it can provide resiliency against distributed denial-of-service (DDoS) attacks, which are attempts to overwhelm a web server with a large number of requests from multiple sources. A CDN can mitigate DDoS attacks by:
Distributing the traffic across multiple servers and locations, making it harder for attackers to target a single point of failure Filtering out malicious requests before they reach the origin server, using techniques such as rate limiting, IP blocking, and challenge-response mechanisms Absorbing the attack traffic with greater bandwidth and resources than the origin server, reducing the impact on the web application's availability and performance Reference: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 4: Security in the Cloud, page 152; Why use a CDN? | CDN benefits | Cloudflare; What Is DNS Security?

NEW QUESTION # 242
A company decides to move some of its computing resources to a public cloud provider but keep the rest in-house. Which of the following cloud migration approaches does this BEST describe?
- A. Hybrid
- B. Lift and shift
- C. Phased
- D. Rip and replace
Answer: A
Explanation:
A hybrid cloud migration approach best describes the scenario where a company decides to move some of its computing resources to a public cloud provider but keep the rest in-house. A hybrid cloud is a type of cloud deployment that combines public and private cloud resources, allowing data and applications to move between them. A hybrid cloud can offer the benefits of both cloud models, such as scalability, cost-efficiency, security, and control. A hybrid cloud migration approach can help a company to leverage the advantages of the public cloud for some workloads, while maintaining the on-premise infrastructure for others. For example, a company may choose to migrate its web applications to the public cloud to improve performance and availability, while keeping its sensitive data and legacy systems in the private cloud for compliance and compatibility reasons. A hybrid cloud migration approach can also enable a gradual transition to the cloud, by allowing the company to move workloads at its own pace and test the cloud environment before fully committing to it.
