A cloud engineer has provisioned a VM for a high-frequency trading application. After the VM is put into production, users report high latency in trades. The engineer checks the last six hours of VM metrics and sees the following:· CPU utilization is between 30% to 60%.· Networkln is between 50Kbps and 70Kbps.· NetworkOut is between 3.000Kpbs and 5.000Kbps.· DiskReadOps is at 30.· DiskWriteOps is at 70· Memory utilization is between 50% and 70%.Which of the following steps should the engineer take next to solve the latency issue?
Answer(s): A
Since the NetworkOut is significantly higher than NetworkIn and considering the nature of a high- frequency trading application, the issue most likely lies with network throughput. Moving to a network-optimized instance type would provide higher network bandwidth, which can reduce latency in trades.
This solution is derived from the Management and Technical Operations domain of theCompTIA Cloud+ objectives, focusing on performance optimization for cloud services.
A cloud engineer was deploying the company's payment processing application, but it failed with the following error log:ERFOR:root: Transaction failed http 429 response, please try again Which of the following are the most likely causes for this error? (Select two).
Answer(s): A,F
The error "http 429 response, please try again" typically indicates API throttling, where the number of requests exceeds the rate limit set by the API provider, and insufficient quota, where the allowed number of API calls within a given timeframe has been exceeded.
API throttling and quota management are key concepts in the management of cloud resources, as highlighted in the CompTIA Cloud+ curriculum.
An organization's web application experiences penodic bursts of traffic when a new video is launched. Users are reporting poor performance in the middle of the month. Which of the following scaling approaches should the organization use to scale based on forecasted traffic?
For periodic bursts of traffic that are predictable, such as when a new video is launched, a scheduled scaling approach is suitable. This strategy involves scaling resources based on forecasted or known traffic patterns, ensuring that the infrastructure can handle the load during expected peak times.
The use of scheduled scaling to manage predictable traffic increases is discussed within the Management and Technical Operations section of the CompTIA Cloud+ exam objectives.
A company uses containers stored in Docker Hub to deploy workloads (or its laaS infrastructure. The development team releases changes to the containers several times per hour. Which of the following should a cloud engineer do to prevent the proprietary code from being exposed to third parties?
Answer(s): D
To prevent proprietary code from being exposed to third parties, a cloud engineer should use private repositories for the containers. Private repositories ensure that access to container images is restricted and controlled, unlike public repositories where images are accessible to anyone.
The concept of using private repositories for protecting proprietary code is part of cloud security best practices, which is covered under the Governance, Risk, Compliance, and Security domain of the CompTIA Cloud+ certification.
Which of the following is an auditing procedure that ensures service providers securely manage the data to protect the interests of the organization and the privacy of its clients?
Answer(s): C
SOC2 (Service Organization Control 2) is an auditing procedure that ensures service providers securely manage data to protect the interests of an organization and the privacy of its clients. SOC2 is specifically designed for service providers storing customer data in the cloud, making it pertinent for data management and privacy.
SOC2 and its role in auditing and ensuring secure data management by cloud service providers are part of the compliance standards and regulations included in the CompTIA Cloud+ certification material.

is the answer to question 15 correct ? i feel like the answer should be b
its getting more technical
i think these questions are what i need.
helpful assessment
i am confused about the answers to the questions. do you know if the answers are correct?
hi, please make the dumps available for my upcoming examination.
good practice
so far it is really informative
hi i want it please please upload it
am preparing for exam ,just nice questions
please upload c_tadm_23 exam
can we get tdvan4 vantage data engineering pdf?
want to clear the exam.
could you please upload the dumps of sap c_sac_2302
asm management configuration is about storage
kool thumb up
just passed the az-500 exam this last friday. most of the questions in this exam dumps are in the exam. i bought the full version and noticed some of the questions which were answered wrong in the free version are all corrected in the full version. this site is good but i wish the had it in an interactive version like a test engine simulator.
i can practice for exam
please i need this exam.
i need the dump
i want it bad, even if cs6 maybe retired, i want to learn cs6
i hate comptia with all my heart with their "choose the best" answer format as an argument could be made on every question. they say "the "comptia way", lmao no this right here boys is the comptia way 100%. take it from someone whos failed this exam twice but can configure an entire complex network that these are the questions that are on the test 100% no questions asked. the pbqs are dead on! nice work
very good materials
thanks for your support.
iam impressed with the quality of these dumps. they questions and answers were easy to understand and the xengine app was very helpful to use.
not bad but you question database from isaca
awesome contents
answer to 134 is casb. while data loss prevention is the goal, in order to implement dlp in cloud applications you need to deploy a casb.
are these brain dumps sufficient enough to go write exam after practicing them? or does one need more material this wont be enough?
i did attend the required cources and i need to be sure that i am ready to take the exam, i would ask you please to share the questions, to be sure that i am fit to proceed with taking the exam.
why only give explanations on some, and not all questions and their respective answers?
refresh db knowledge
interested for sap certification
could you please upload practice questions for scr exam ?
