Question No. 1

A cloud administrator needs to reduce storage costs. Which of the following would best help the administrator reach that goal?

AEnabling compression

BImplementing deduplication

CUsing containers

DRightsizing the VMs

Show Answer

Correct Answer: B

Deduplication is a process by which redundant data is eliminated, thus reducing the size of the dataset.Deduplication with cloud storage reduces the storage requirements, along with the amount of data to be transferred over the network, resulting in faster and more efficient data protection operations1.Deduplication can help to shrink the data footprint, lower the storage costs, and improve the performance of backup and recovery processes2.Deduplication can be applied at different levels, such as file-level, block-level, or byte-level, depending on the granularity and efficiency of the technique3.Deduplication can also be performed at different locations, such as source, target, or cloud, depending on the architecture and design of the storage system3.By implementing deduplication, a cloud administrator can achieve significant data savings and optimize the cloud storage costs4.Reference:Data deduplication techniques for efficient cloud storage management: a systematic review;How Data Deduplication Reduces Cloud Data Costs;How Data Deduplication Can Save Cloud Storage Costs?;Data Deduplication Overview;What is Data Deduplication and How Can it Help Reduce Cloud Costs?.

Question No. 2

A company has applications that need to remain available in the event of the data center being unavailable. The company's cloud architect needs to find a solution to maintain business continuity. Which of following should the company implement?

AA DR solution for the application between different data centers

BAn off-site backup solution with a third-party vendor

ClaC techniques to recreate the system at a new provider

DAn HA solution for the application inside the data center

Show Answer

Correct Answer: A

A disaster recovery (DR) solution is a set of policies, procedures, and tools that enable an organization to restore or continue its critical functions in the event of a natural or human-induced disaster. A DR solution for the application between different data centers means that the application is replicated or backed up to another location that is geographically separated from the primary data center. This way, if the primary data center becomes unavailable due to a power outage, fire, flood, cyberattack, or any other cause, the application can be switched over to the secondary data center and resume its operations with minimal downtime and data loss. This solution ensures business continuity and high availability for the application and its users.Reference: CompTIA Cloud+ CV0-003 Study Guide, Chapter 5: Maintaining a Cloud Environment, page 221-222;Disaster recovery planning guide.

Question No. 3

A company is comparing an application environment to be hosted on site versus a SaaS model of the same application. Which of the following SaaS-based licensing models should the administrator consider?

APer core

BPer socket

CPer instance

DPer user

Show Answer

Correct Answer: D

Per user is a common SaaS-based licensing model that charges customers based on the number of users who access the software. This model is suitable for applications that have a clear and consistent user base, such as CRM, ERP, or collaboration tools. Per user licensing allows customers to scale up or down their usage as their needs change, and only pay for what they use. Per user licensing also simplifies the billing and management of the software, as customers do not need to worry about the underlying infrastructure, hardware, or software updates.Reference: CompTIA Cloud+ CV0-003 Study Guide, Chapter 1: Cloud Concepts and Models, page 19;SaaS Licensing.

Question No. 4

During a security incident on an laaS platform, which of the following actions will a systems administrator most likely take as part of the containment procedure?

AConnect to an instance for triage.

BAdd a deny rule to the network ACL.

CMirror the traffic to perform a traffic capture.

DPerform a memory acquisition.

Show Answer

Correct Answer: B

A network access control list (ACL) is a set of rules that controls the inbound and outbound traffic for a network interface or a subnet. A deny rule can be used to block or filter the traffic from a specific source or destination, such as an IP address, a port number, or a protocol. By adding a deny rule to the network ACL, a systems administrator can prevent the communication between the compromised instance and the attacker, or between the compromised instance and other instances or servers. This can help to contain the security incident and limit the potential damage or data loss. A deny rule can also be used to isolate the compromised instance for further investigation or remediation.Reference: CompTIA Cloud+ CV0-003 Study Guide, Chapter 5: Maintaining a Cloud Environment, page 222-223;What is a network access control list (ACL)?.

Question No. 5

A systems administrator is implementing a new version of a company's primary human-resources application. An upgrade will be performed on the production server, as there is no development environment. The administrator needs to have a

plan in case something goes wrong with the upgrade. Which of the following will work best to ensure a quick rollback in case an issue arises?

AAn application-level backup

BA production snapshot

CA full backup

DA differential backup

Show Answer

Correct Answer: B

A production snapshot is a point-in-time copy of the state and data of a production server or instance. It can be used to restore the server or instance to the exact state it was in when the snapshot was taken, in case of a failure, error, or corruption. A production snapshot can help to ensure a quick rollback in case an issue arises during an application upgrade, as it can revert the changes made by the upgrade and restore the previous version of the application. A production snapshot can also preserve the configuration and settings of the server or instance, as well as the application data and dependencies. A production snapshot is different from a backup, which is a copy of the data only, and may not include the state or configuration of the server or instance.Reference: CompTIA Cloud+ CV0-003 Study Guide, Chapter 2: Deploying a Cloud Environment, page 75-76;Snapshots vs Backups: Key Differences and Similarities.
