• Question 231:

  A cloud engineer is troubleshooting an application that consumes multiple third-party REST APIs. The application is randomly experiencing high latency. Which of the following would best help determine the source of the latency?

  A. Configuring centralized logging to analyze HTTP requests
  B. Running a flow log on the network to analyze the packets
  C. Configuring an API gateway to track all incoming requests
  D. Enabling tracing to detect HTTP response times and codes
  D. Enabling tracing to detect HTTP response times and codes

  ---

  Explanation

  Enabling tracing in the application can help determine the source of high latency by providing detailed information on HTTP request and response times, as well as response codes. This can identify which API calls are experiencing delays and contribute to overall application latency, allowing for targeted troubleshooting and optimization.

• Question 232:

  An organization needs to retain its data for compliance reasons but only when required. Which of the following would be the most cost-effective type of tiered storage?

  A. Warm
  B. Hot
  C. Archive
  D. Cold
  C. Archive

  ---

  Explanation

  Archive storage is the most cost-effective type of tiered storage for retaining data that is infrequently accessed and only when required for compliance reasons. It is designed for long-term storage and offers lower storage costs compared to hot, cold, or warm storage tiers.

  References: Understanding data storage and the various tiers, including archival storage, is part of cloud storage strategies covered in the CompTIA Cloud+ certification.

• Question 233:

  A systems administrator needs to configure a script that will monitor whether an application is healthy and stop the VM if an unsuccessful code is returned.

  Which of the following scripts should the systems administrator use to achieve this goal?

  A. RESPONSE_CODE }string APP_URLbool RESPONSE_CODEstring VMhealth checker (APP_URL, VM) {if [ http_probe (APP_URL) == 200] {echo RESPONSE_CODE }else{stop (VM)echo
  B. else{echostring APP_URLfloat RESPONSE_CODEstring VMhealth_checker (APP_URL, VM) {if [ http_probe (APP_URL) == 200] {stop (RESPONSE_CODE)echo VM }stop (VM)RESPONSE CODE }
  C. else{echostring APP_URLint RESPONSE CODEstring VMhealth checker (APP_URL, VM) {if [ http_probe (APP_URL) == 200] {echo RESPONSE_CODE }stop (VM)RESPONSE_CODE }
  D. else{echostring APP_URLint RESPONSE_CODEstring VMhealth_checker (APP_URL, VM) {if [ http_probe (VM) == 200] {stop (VM)echo RESPONSE_CODE }RESPONSE CODE }
  A. RESPONSE_CODE }string APP_URLbool RESPONSE_CODEstring VMhealth checker (APP_URL, VM) {if [ http_probe (APP_URL) == 200] {echo RESPONSE_CODE }else{stop (VM)echo

  ---

  Explanation

  Script A is designed to monitor the health of an application by checking its response code. If the application returns a 200 (OK) status, it indicates that the application is healthy. Otherwise, the script will stop the VM to address the issue, which is a common approach to handle unhealthy application states in automated environments. This script effectively achieves the goal of monitoring application health and taking corrective action when an unsuccessful code is returned.

• Question 234:

  A cloud administrator is working on the deployment of an e-commerce website. The administrator evaluates the scaling methods to be implemented when seasonal or flash sales are launched.

  Which of the following scaling approaches should the administrator use to best manage this scenario?

  A. Scheduled
  B. Load
  C. Event
  D. Trending
  B. Load

  ---

  Explanation

• Question 235:

  A cloud solutions architect needs to design a solution that will collect a report and upload it to an object storage service every time a virtual machine is gracefully or non-gracefully stopped.

  Which of the following will best satisfy this requirement?

  A. An event-driven architecture that will send a message when the VM shuts down to a log- collecting function that extracts and uploads the log directly from the storage volume
  B. Creating a webhook that will trigger on VM shutdown API calls and upload the requested files from the volume attached to the VM into the object-defined storage service
  C. An API of the object-defined storage service that will scrape the stopped VM disk and self-upload the required files as objects
  D. A script embedded on the stopping VM's OS that will upload the logs on system shutdown
  A. An event-driven architecture that will send a message when the VM shuts down to a log- collecting function that extracts and uploads the log directly from the storage volume

  ---

  Explanation

  An event-driven architecture is suited for this scenario, where an event (like a VM shutdown) triggers a function to execute specific tasks (log collection and upload). This approach is efficient and ensures that the logs are collected and uploaded to an object storage service every time the VM is stopped, regardless of whether it is a graceful or non- graceful shutdown.

• Question 236:

  A security team recently hired multiple interns who all need the same level of access. Which of the following controls should the security team implement to provide access to the cloud environment with the least amount of overhead?

  A. MFA
  B. Discretionary access
  C. Local user access
  D. Group-based access control
  D. Group-based access control

  ---

  Explanation

  Implementing group-based access control is the most efficient way to provide access to multiple interns who require the same level of access. This method allows the security team to assign permissions to a group rather than to individual user accounts, thereby reducing the administrative overhead involved in managing access rights for each intern individually.

• Question 237:

  A log-parsing application requires significant processing power to ingest the logs streaming from web servers. The engineering team presents the cloud architect with four proposals using the same underlying hardware.

  Which of the following should the cloud architect select in order to minimize the impact of an instance failure while keeping the cost as low as possible?

  A. Four instances of 4vCPU, 8GB RAM, 80GB SSD
  B. Four instances of 4vCPU, 8GB RAM, 80GB HDD
  C. Two instances of 8vCPU, 16GB RAM, 80GB SSD
  D. Two instances of 8vCPU, 16GB RAM, 80GB HDD
  A. Four instances of 4vCPU, 8GB RAM, 80GB SSD

  ---

  Explanation

  Choosing four instances with the given specifications would distribute the load and reduce the impact of any single instance failure. Using SSDs over HDDs would provide faster data processing capabilities which is crucial for a log-parsing application. This setup also retains cost efficiency by not over-provisioning resources.

• Question 238:

  A cloud engineer is in charge of deploying a platform in an laaS public cloud. The application tracks the state using session cookies, and there are no affinity restrictions.

  Which of the following will help the engineer reduce monthly expenses and allow the application to provide the service?

  A. Resource metering
  B. Reserved resources
  C. Dedicated host
  D. Pay-as-you-go model
  D. Pay-as-you-go model

  ---

  Explanation

  A pay-as-you-go model would be beneficial for the cloud engineer because it allows the application to be scaled based on demand, reducing monthly expenses since costs are only incurred for the resources actually used. Since there are no affinity restrictions and the application uses session cookies for state tracking, the pay-as-you-go model can handle fluctuating workloads without the need to pay for unused reserved resources or dedicated hosts.

• Question 239:

  A company wants to implement a work environment that will have low operational overhead and highly accessible enterprise resource planning, email, and data resources. Which of the following cloud service models should the company implement?

  A. laaS
  B. PaaS
  C. DBaaS
  D. SaaS
  D. SaaS

  ---

  Explanation

  A company that requires low operational overhead and highly accessible enterprise resources would benefit from implementing Software as a Service (SaaS). SaaS provides access to applications hosted in the cloud, eliminating the need for internal infrastructure or application development, which aligns with the requirement of having low operational overhead.

• Question 240:

  An IT manager is migrating the production environment to the cloud but needs to keep control of the operating systems, patches, and settings of all resources. Which of the following deployment models will best meet the requirements?

  A. FaaS
  B. PaaS
  C. laaS
  D. SaaS
  C. laaS

  ---

  Explanation

  Infrastructure as a Service (IaaS) is the deployment model that will best meet the requirements of retaining control over the operating systems, patches, and settings of all resources. IaaS provides the cloud infrastructure but leaves the management of the operating system and applications to the user.References: The cloud service models and the level of control they offer are fundamental topics in the CompTIA Cloud+ certification material.
