After a hardware upgrade on a private cloud system, the systems administrator notices a considerable drop in network performance. Which of the following is MOST likely the cause?
A. The driver
B. The memory
C. The cluster placement
D. The CPU
Correct Answer: A
The driver is the most likely cause of the drop in network performance after a hardware upgrade on a private cloud system. A driver is a software component that enables communication and interaction between hardware devices and operating systems or applications. A driver may need to be updated or reinstalled after a hardware upgrade to ensure compatibility and functionality. If the driver is outdated, missing, or corrupted, it may affect the network performance of the system.
Question 324:
Due to a policy change, a few of a customer's application VMs have been migrated to synchronously replicated storage. The customer now reports that performance is lower. The systems administrator checks the resource usage and discovers CPU utilization is at 60% and available memory is at 30%.
Which of the following is the MOST likely cause?
A. There is not enough vCPU assigned
B. The application is not compatible with the new settings
C. The new configuration is adding latency
D. The memory of the VM is underallocated
Correct Answer: C
Latency is the delay or time taken for data to travel from one point to another in a network or system. Latency can affect the performance of applications and processes that depend on fast and reliable data transfer. Synchronous replication is a method of data replication that ensures that data is written to two or more storage devices at the same time, providing high availability and consistency. However, synchronous replication can also introduce latency, as the write operation has to wait for the confirmation from all the replicated devices before completing. The new configuration of migrating some application VMs to synchronously replicated storage is most likely adding latency, which can lower the performance of the applications.

Question 325:
An organization purchased new servers with GPUs for render farms. The servers have limited CPU resources.
Which of the following GPU configurations will be the MOST optimal for virtualizing this environment?
A. Dedicated
B. Shared
C. Passthrough
D. vGPU
Correct Answer: C
Passthrough is a type of GPU configuration that allows a VM to directly access a physical GPU on the host system without any virtualization layer or sharing mechanism. Passthrough can provide optimal performance and compatibility for GPU- intensive applications, such as rendering or gaming, as it eliminates any overhead or contention caused by virtualization or sharing. Passthrough is also suitable for servers with limited CPU resources, as it reduces the CPU load and offloads the graphics processing to the GPU. Passthrough is the most optimal GPU configuration for virtualizing a new server with GPUs for render farms. References: CompTIA Cloud+ Certification Exam Objectives, page 11, section 1.6
Question 326:
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. Identify the resources that are accessible to the affected IAM user
B. Remove the published plain-text password
C. Notify users that a data breach has occurred
D. Change the affected IAM user's password
E. Delete the affected IAM user
Correct Answer: BD
The first step a cloud administrator should take after accidentally uploading a password for an IAM user in plain text is to remove the published plain-text password. This should be done immediately to prevent unauthorized access to the affected user's resources. The administrator should then change the password for the affected IAM user to a new, strong password. This will ensure that the user's resources are secure and that there is no unauthorized access.
A. Identifying the resources that are accessible to the affected IAM user is important, but it should not be done before removing the plain-text password and changing the password for the affected user. This step can be taken after the immediate security concerns have been addressed.
C. While it is important to notify users of a data breach, this step is not necessary in this situation as the password was accidentally uploaded and there is no evidence that any unauthorized access has occurred. However, the cloud administrator should review their security protocols to ensure that similar incidents do not occur in the future.
E. Deleting the affected IAM user is not necessary in this situation, as the user's resources can be secured by changing the password. Deleting the user may cause unnecessary disruption to the user's workflow and could result in the loss of important data.
In summary, the first step a cloud administrator should take after accidentally uploading a password for an IAM user in plain text is to remove the published plain-text password, followed by changing the password for the affected user.
Question 327:
An organization has the following requirements that need to be met when implementing cloud services:
1.
SSO to cloud infrastructure
2.
On-premises directory service
3.
RBAC for IT staff
Which of the following cloud models would meet these requirements?
A. Public
B. Community
C. Hybrid
D. Multitenant
Correct Answer: C
A hybrid cloud is a type of cloud deployment model that combines two or more different types of clouds, such as public, private, or community clouds, into a single integrated environment. A hybrid cloud can meet the requirements for implementing cloud services with SSO to cloud infrastructure, on-premises directory service, and RBAC for IT staff, as it can provide flexibility, scalability, and security for cloud-based and on-premises resources. A hybrid cloud can also enable seamless and secure access to cloud infrastructure using SSO with directory service federation, as well as granular and consistent control over IT staff permissions using RBAC across different cloud environments.

Question 328:
A cloud administrator is reviewing the authentication and authorization mechanism implemented within the cloud environment. Upon review, the administrator discovers the sales group is part of the finance group, and the sales team members can access the financial application. Single sign-on is also implemented, which makes access much easier.
Which of the following access control rules should be changed?
A. Discretionary-based
B. Attribute-based
C. Mandatory-based
D. Role-based
Correct Answer: D
Role-based access control (RBAC) is a type of access control model that assigns permissions and privileges to users based on their roles or functions within an organization or system. RBAC can help simplify and streamline the management and enforcement of access policies, as it can reduce the complexity and redundancy of assigning permissions to individual users or groups. RBAC can also help improve security and compliance, as it can limit or grant access based on the principle of least privilege and the separation of duties. RBAC is the best access control rule to change when the sales group is part of the finance group and the sales team members can access the financial application due to a single sign-on mechanism being implem
A company that utilizes an IaaS service provider has contracted with a vendor to perform a penetration test on its environment. The vendor is able to exploit the virtualization layer and obtain access to other instances within the cloud provider's environment that do not belong to the company.
Which of the following BEST describes this attack?
A. VM escape
B. Directory traversal
C. Buffer overflow
D. Heap spraying
Correct Answer: A
VM escape is a type of attack that allows an attacker to break out of a virtual machine (VM) and access the host system or other VMs within the same cloud provider's environment. VM escape can exploit the vulnerabilities in the virtualization layer or hypervisor that separates and isolates the VMs from each other and from the host system. VM escape can result in serious consequences, such as compromising the security and privacy of other customers' data or resources, gaining unauthorized access to the cloud provider's infrastructure or services, or launching further attacks on other systems or networks. VM escape best describes the attack that was performed by a vendor who was able to exploit the virtualization layer and obtain access to other instances within the cloud provider's environment that do not belong to the company.
