In this era of the latest technology, we should incorporate interesting facts, figures, visual graphics, and other tools that can help people read the CompTIA Cloud+ Certification Exam (CV0-003) exam questions with interest. ExamcollectionPass uses pictures that are related to the CV0-003 certification exam and can even add some charts, and graphs that show the numerical values. It will not let the reader feel bored with the CV0-003 Practice Test. They can engage their attention in CompTIA CV0-003 exam visual effects and pictures that present a lot of.

CompTIA Cloud+ Certification is a well-recognized certification in the IT industry. It is designed to validate the skills and knowledge of professionals who work with cloud computing technologies. CompTIA Cloud+ Certification Exam certification is vendor-neutral, which means it is not tied to any specific cloud platform or vendor. This makes it an ideal certification for IT professionals who work with multiple cloud platforms.

CompTIA Cloud+ Certification Exam Sample Questions (Q177-Q182):

NEW QUESTION # 177
Which of the following will provide a systems administrator with the MOST information about potential attacks on a cloud IaaS instance?

A. FIM
B. HIDS
C. Software firewall
D. Network flows

Answer: B

Explanation:
Explanation
HIDS (Host-based Intrusion Detection System) is the tool that will provide the administrator with the most information about potential attacks on a cloud IaaS instance. HIDS is a software or agent that monitors and analyzes the activities and events on a host system or device, such as a cloud instance. HIDS can detect and alert on any malicious or anomalous behavior, such as unauthorized access, malware infection, configuration changes, etc., that may indicate an attack or compromise.

NEW QUESTION # 178
A cloud administrator is monitoring a database system and notices an unusual increase in the read operations, which is causing a heavy load in the system. The system is using a relational database and is running in a VM. Which of the following should the administrator do to resolve the issue with minimal architectural changes?

A. Migrate the relational database to a NoSQL database.
B. Use a cache system to store reading operations.
C. Create a secondary standby database instance.
D. Implement the database system using a DBaaS.

Answer: B

Explanation:
The best way to resolve the issue of an unusual increase in the read operations that is causing a heavy load in the system that is using a relational database and is running in a VM is to use a cache system to store reading operations. A cache system is a type of storage system that temporarily stores frequently accessed or recently used data in memory for faster retrieval. A cache system can reduce the load on the database system by serving the read requests from the cache instead of querying the database every time. Reference: [CompTIA Cloud+ Certification Exam Objectives], Domain 4.0 Troubleshooting, Objective 4.3 Given a scenario, troubleshoot capacity issues within a cloud environment.

NEW QUESTION # 179
Following the deployment of a new VM, a cloud engineer notices the backup platform has not added the machine to the appropriate job. The backup platform uses a text-based variable for job configuration. This variable is based on the RPO requirements for the workload. Which of the following did the cloud engineer forget to configure when deploying the virtual machine?

A. RPO
B. Server name
C. Tags
D. RTO

Answer: C

Explanation:
Template
Explanation:
Tags are key-value pairs that can be applied to cloud resources to organize, categorize, and filter them. Tags can also be used to assign resources to backup jobs based on their RPO requirements. The cloud engineer forgot to configure the appropriate tag for the new VM that matches the text-based variable of the backup platform. Therefore, the backup platform did not add the VM to the correct job. Reference: Tags and labels | Cloud Storage | Google Cloud, CompTIA Cloud+ Certification Exam Objectives, Domain 4.0: Operations and Support, Objective 4.3: Given a scenario, apply the appropriate methods for cost control in a cloud environment.

NEW QUESTION # 180
A systems administrator recently upgraded the processors in a web application host. Upon the next login, the administrator sees a new alert regarding the license being out of compliance.
Which of the following licensing models is the application MOST likely using?

A. Per device
B. Volume-based
C. Per user
D. Core-based

Answer: D

Explanation:
Core-based licensing is a type of licensing model that charges based on the number of processor cores in a system or server. Core-based licensing is often used by software vendors to align their pricing with the performance and capacity of modern hardware. Core-based licensing can also enable customers to optimize their licensing costs by choosing the appropriate hardware configuration for their needs. Upgrading the processors in a web application host can affect the core-based licensing of the application, as it may increase the number of cores that need to be licensed. This can result in an alert regarding the license being out of compliance if the license is not updated accordingly. Reference: CompTIA Cloud+ Certification Exam Objectives, page 20, section 4.2

NEW QUESTION # 181
A systems administrator is working within a private cloud environment. Over time. random 4K read/write speeds on all VMS in the environment slow down until the VMS are completely unusable, with disk speeds of less than 1MBps. The administrator has gathered the information below:
* There is no correlation between the slowdown and VM/hypervisor resource utilization.
* The network is rated to 40Gbps and utilization is between 1-5%.
* The hypervisors use hundreds of NFSv3 mounts to the same storage appliance, one per VM.
* The VMS on each hypervisor become unresponsive after two weeks of uptime.
* The unresponsiveness is resolved by moving slow VMS onto a rebooted hypervisor.
Which of the following solutions will MOST likely resolve this issue?

A. Reduce the number of NFSv3 mounts to one.
B. Configure jumbo frames on the hypervisors and storage.
C. Increase CPU/RAM resources on affected VMS.
D. Increase caching on the storage appliance.

Answer: A

Explanation:
Explanation
The correct answer is D. Reduce the number of NFSv3 mounts to one.
NFSv3 is a network file system protocol that allows clients to access files stored on a remote server. NFSv3 uses TCP or UDP as the transport layer protocol, and typically runs on port 20491.
One of the known issues with NFSv3 mounts is that they can cause performance degradation and unresponsiveness on the client side if there are too many mounts or if there are network connectivity problems.
This is because NFSv3 does not handle connection failures or timeouts gracefully, and may keep retrying to access the server indefinitely, blocking other processes or threads. This can result in slow disk speeds, high CPU usage, and system hangs23.
Therefore, one of the possible solutions to this issue is to reduce the number of NFSv3 mounts to one per hypervisor, instead of one per VM. This way, the hypervisor can manage the access to the shared storage appliance more efficiently, and avoid creating too many TCP connections or UDP packets that may overload the network or the server. Reducing the number of NFSv3 mounts can also simplify the configuration and troubleshooting of the network file system.
Increasing caching on the storage appliance may improve the read performance of the NFSv3 mounts, but it will not solve the underlying issue of connection failures or timeouts. Caching may also introduce data inconsistency or corruption issues if the cache is not synchronized with the server.
Configuring jumbo frames on the hypervisors and storage may improve the network throughput and efficiency of the NFSv3 mounts, but it will not solve the underlying issue of connection failures or timeouts. Jumbo frames are larger than standard Ethernet frames, and require that all devices on the network path support them.
Jumbo frames may also introduce fragmentation or compatibility issues if they are not configured properly.
Increasing CPU/RAM resources on affected VMs may improve their performance in general, but it will not solve the underlying issue of connection failures or timeouts. Increasing CPU/RAM resources may also be costly and wasteful if they are not needed for other purposes.
