Question # 1 An IT security team wants to ensure that the correct parties are informed when a specific user account is signed in. Which of the following would most likely allow an administrator to address this concern? A. Creating an alert based on user sign-in criteriaB. Aggregating user sign-in logs from all systemsC. Enabling the collection of user sign-in logsD. Configuring the retention of all sign-in logs
Click for Answer
A. Creating an alert based on user sign-in criteria
Answer Description Explanation:
To ensure that the correct parties are informed when a specific user account is signed in, the best action is to create an alert based on user sign-in criteria. This alert can notify administrators or security personnel when the specified event occurs.References: Security monitoring and alerting are critical components of managing cloud environments securely, as discussed in the CompTIA Cloud+ certification.
Question # 2 Which of the following provides secure, private communication between cloud environments without provisioning additional hardware or appliances? A. VPNB. VPC peering
C. BGPD. Transit gateway
Click for Answer
B. VPC peering
Answer Description Explanation :
VPC peering provides secure, private communication between cloud environments without the need for provisioning additional hardware or appliances. It allows direct network connectivity between two Virtual Private Clouds (VPCs), enabling resources in either VPC to communicate with each other using private IP addresses.
Question # 3 A high-usage cloud resource needs to be monitored in real time on specific events to guarantee its availability. Which of the following actions should be used to meet this requirement? A. Configure a ping command to identify when the cloud instance is out of service.
B. Create a dashboard with visualizations to filter the status of critical activities.
C. Collect all the daily activity from the cloud instance and create a dump file for analysis.
D. Schedule an hourly scan of the network to check for the availability of the resource.
Click for Answer
B. Create a dashboard with visualizations to filter the status of critical activities.
Answer Description Explanation :
To guarantee real-time monitoring of a high-usage cloud resource, creating a dashboard with visualizations to filter the status of critical activities is effective. This allows for a quick visual assessment of the system's health and performance, enabling immediate action if specific events indicate potential issues with availability.
Question # 4 Which of the following integration systems would best reduce unnecessary network traffic by allowing data to travel bidirectionally and facilitating real-time results for developers who need to display critical information within applications? A. REST APIB. RPCC. GraphQLD. Web sockets
Click for Answer
D. Web sockets
Answer Description Explanation:
Web sockets provide a full-duplex communication channel over a single, long-lived connection, allowing data to flow bidirectionally between a client and a server. This is ideal for real-time applications where developers need to display critical information without unnecessary network overhead, as it reduces the need for repetitive HTTP requests and allows for more efficient, instantaneous data updates and interactions.
Question # 5 Which of the following would allow a cloud engineer to flatten a deeply nested JSON log to improve readability for analysts? A. GrafanaB. KibanaC. Elastic searchD. Log stash
Click for Answer
D. Log stash
Answer Description Explanation:
Log stash can be used to flatten a deeply nested JSON log, which would improve readability for analysts. Log stash is a data processing pipeline that ingests data from various sources, transforms it, and then sends it to a "stash" like Elastic search.

Question # 6 A systems administrator needs to configure backups for the company's on-premises VM cluster. The storage used for backups will be constrained on free space until the company can implement cloud backups. Which of the following backup types will save the most space, assuming the frequency of backups is kept the same? A. SnapshotB. FulC. DifferentialD. Incremental
Click for Answer
D. Incremental
Answer Description Explanation:
An incremental backup strategy saves space because it only backs up data that has changed since the last backup. Compared to full and differential backups, incremental backups aresmaller and save more space, which is essential when storage is constrained. References: CompTIA Cloud+ Guide to Cloud Computing (ISBN: 978-1-64274-282-2)
Question # 7 A developer at a small startup company deployed some code for a new feature to its public repository. A few days later, a data breach occurred. A security team investigated the incident and found that the database was hacked. Which of the following is the most likely cause of this breach? A. Database core dumpB. Hard-coded credentialsC. Compromised deployment agentD. Unpatched web servers
Click for Answer
B. Hard-coded credentials
Answer Description Hard-coded credentials within code, especially when deployed in a public repository, are a common security vulnerability. If credentials such as passwords or API keys are embedded in the code, anyone with access to the repository can potentially use them to gain unauthorized access to databases or other sensitive resources. This is a likely cause of the data breach in the scenario described. References: CompTIA Security+ Guide to Network Security Fundamentals by Mark Ciampa.
Question # 8 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). A. API throttlingB. API gateway outageC. Web server outageD. OversubscriptionE. Unauthorized access
Click for Answer
A. API throttling
Answer Description Explanation:
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.References: API throttling and quota management are key concepts in the management of cloud resources, as highlighted in the CompTIA Cloud+ curriculum.
