正解：A
解説：
Renewing the expired certificate is what would most likely resolve the issue of users receiving a message indicating the connection is not secure when landing on a website that is hosted on a cloud platform and accessed through https://www.comptiasite.com. A certificate is a digital document that contains information such as identity, public key, expiration date, etc., that can be used to prove one's identity and establish secure communication over a network. A certificate can expire when it reaches its validity period and needs to be renewed or replaced. An expired certificate can cause users to receive a message indicating the connection is not secure by indicating that the website's identity or security cannot be verified or trusted. Renewing the expired certificate can resolve the issue by extending its validity period and restoring its identity or security verification or trust.

Which of the following will provide the data to measure business continuity? (Choose two.)
- A. A recovery time objective
- B. A network diagram
- C. A service-level agreement
- D. Playbooks
- E. A backup and restore
- F. Automation scripts
正解：A、C
解説：
Explanation
A service-level agreement (SLA) is a contract or document that defines the level of service and performance expected from a service provider or vendor. A recovery time objective (RTO) is a metric that specifies the maximum acceptable time for restoring a system or service after a disruption or outage. Both SLA and RTO can provide the data to measure business continuity, as they can indicate the availability, reliability, and recoverability of a system or service in case of a failure or disaster. SLA and RTO can also help evaluate the effectiveness and efficiency of the business continuity plan and solution. References: CompTIA Cloud+ Certification Exam Objectives, page 20, section 4.2

質問 # 102
A systems administrator is troubleshooting performance issues with a Windows VDI environment. Users have reported that VDI performance is very slow at the start of the workday, but the performance is fine during the rest of the day. Which of the following is the MOST likely cause of the issue? (Choose two.)
- A. RAM usage
- B. Affinity rule
- C. CPU oversubscription
- D. License issues
- E. Disk I/O limits
- F. Insufficient GPU resources
正解：C、E
解説：
Disk I/O limits are restrictions or controls that limit the amount of disk input/output operations per second (IOPS) that a VM can perform on a storage device or system. CPU oversubscription is a situation where more CPU resources are allocated to VMs than are physically available on the host or server. Disk I/O limits and CPU oversubscription are most likely to cause VDI performance being very slow at the start of the workday, but fine during the rest of the day, as they can create bottlenecks or contention for disk and CPU resources when multiple users log in or launch their VDI sessions at the same time, resulting in increased latency or reduced throughput for VDI operations. Reference: CompTIA Cloud+ Certification Exam Objectives, page 9, section 1.4

A systems administrator is setting up a backup solution to follow the 3-2-1 policy. Currently, the solution is set to back up from the servers to an on-site storage server. Which of the following should the administrator configure to comply with the 3-2-1 policy?
- A. Storage snapshots
- B. A second on-site storage server for backups
- C. Weekly lull backups, with daily incremental backups
- D. An off-site storage server for backups
正解：D
解説：
Explanation
The 3-2-1 backup policy states that there should be three copies of data, stored on two different media, with one copy being off-site. The current backup solution only has one copy of data on one media (the on-site storage server). To comply with the 3-2-1 policy, the systems administrator should configure an off-site storage server for backups, which will provide another copy of data on a different media and location.

質問 # 106
Which of the following cloud deployment models allows a company to have full control over its IT infrastructure?
- A. Public
- B. Hybrid
- C. Cloud within a cloud
- D. Private
正解：D
解説：
A private cloud is a type of cloud deployment model that provides cloud services exclusively to a single organization or tenant. A private cloud allows a company to have full control over its IT infrastructure, as it can customize, configure, manage, and secure its own cloud environment according to its specific needs and preferences. A private cloud can also offer higher performance, reliability, and privacy than other cloud deployment models, as it does not share resources or data with other customers. Reference: CompTIA Cloud+ Certification Exam Objectives, page 8, section 1.2
質問 # 107
A web-application company recently released some new marketing promotions without notifying the IT staff. The systems administrator has since been noticing twice the normal traffic consumption every two hours for the last three hours in the container environment. Which of the following should the company implement to accommodate the new traffic?
- A. Ballooning
- B. Switches
- C. Autoscaling
- D. A firewall
正解：C
解説：
According to the CompTIA Cloud+ Study Guide1, 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 help a cloud environment adjust to changes in traffic and workload, such as the ones caused by the new marketing promotions.
Ballooning, on the other hand, is "a technique used by hypervisors to reclaim unused memory from a virtual machine and allocate it to another virtual machine that needs more memory". This means that ballooning can help optimize the memory usage of a cloud environment, but it does not affect the number of resources allocated to a cloud service.
A firewall is "a device or software that monitors and controls the incoming and outgoing network traffic based on predefined rules". This means that a firewall can help protect a cloud environment from unauthorized access and malicious attacks, but it does not affect the number of resources allocated to a cloud service.
Switches are "devices that connect multiple devices on a network and forward data packets between them". This means that switches can help improve the network performance and connectivity of a cloud environment, but they do not affect the number of resources allocated to a cloud service.
Based on this information, I think the best answer to your question is D.
Autoscaling. Autoscaling can help the company accommodate the new traffic by automatically increasing or decreasing the number of resources allocated to their web-application service based on the current demand. This can also help reduce costs and improve performance and availability.
I hope this helps you understand the concept of autoscaling better. If you want to learn more about CompTIA Cloud+, you can check out some of these resources:

AI is a branch of computer science that aims to create machines or systems that can perform tasks that normally require human intelligence, such as reasoning, learning, decision making, etc. AI can be used to analyze images and extract information such as objects, faces, text, emotions, etc., using techniques such as computer vision, machine learning, natural language processing, etc. AI can help to find content in images faster, more accurately, and more efficiently than manual methods.
質問 # 110
A systems administrator is informed that a database server containing PHI and PII is unencrypted. The environment does not support VM encryption, nor does it have a key management system. The server needs to be able to be rebooted for patching without manual intervention.
Which of the following will BEST resolve this issue?
- A. Enable protocol encryption between the storage and the hypervisor
- B. Enable volume encryption on the storage
- C. Create an IPSec tunnel between the database server and its clients
- D. Ensure all database queries are encrypted
- E. Enable OS encryption
正解：B
解説：
Explanation
Volume encryption is a type of encryption that protects data at the storage level by encrypting an entire disk or partition. Volume encryption can provide strong security for data at rest, as it prevents unauthorized access to the data even if the storage device is lost, stolen, or compromised. Volume encryption can also support automatic booting without manual intervention, as it can use a pre-boot authentication mechanism that does not require user input. Enabling volume encryption on the storage is the best way to resolve the issue of having an unencrypted database server containing PHI and PII, as it can protect the sensitive data without relying on VM encryption or a key management system.

質問 # 111
After accidentally uploading a password for an IAM user in plain text, which of the following should a cloud administrator do FIRST? (Choose two.)
- A. Change the affected IAM user's password
- B. Identify the resources that are accessible to the affected IAM user
- C. Notify users that a data breach has occurred
- D. Delete the affected IAM user
- E. Remove the published plain-text password
正解：A、E
解説：
Removing the published plain-text password and changing the affected IAM user's password are the first actions that a cloud administrator should take after accidentally uploading a password for an IAM user in plain text, as they can prevent or limit any unauthorized or malicious access to the cloud resources or services using the compromised password. Removing the published plain-text password can ensure that the password is not exposed or available to anyone who may access or view the uploaded file. Changing the affected IAM user's password can ensure that the password is updated and secured using encryption or hashing techniques. Reference: CompTIA Cloud+ Certification Exam Objectives, page 14, section 2.7
