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.
Question # 2 Following a ransomware attack, the legal department at a company instructs the IT administrator to store the data from the affected virtual machines for a minimum of one year. Which of the following is this an example of? A. RecoverabilityB. RetentionC. EncryptionD. Integrity
Click for Answer
B. Retention
Answer Description The instruction by the legal department to store data from the affected virtual machines for a minimum of one year is an example of data Retention. Retention policies are often driven by regulatory compliance requirements and dictate how long certain types of data must be kept before they can be securely disposed of. References: CompTIA Cloud+ Study Guide (Exam CV0-004) by Todd Montgomery and Stephen Olson
Question # 3 A cloud service provider requires users to migrate to a new type of VM within three months. Which of the following is the best justification for this requirement? A. Security flaws need to be patched.B. Updates could affect the current state of the VMs.C. The cloud provider will be performing maintenance of the infrastructure.D. The equipment is reaching end of life and end of support.
Click for Answer
D. The equipment is reaching end of life and end of support.
Answer Description The best justification for a cloud service provider requiring users to migrate to a new type of VM within a specific time frame is that the equipment is reaching end of life and end of support (EOL/EOS). This means that the older type of VM will no longer receive updates or support, which could include important security patches, so it is necessary to move to newer VM types to maintain security and performance. References: CompTIA Cloud+ Study Guide (Exam CV0-004) by Todd Montgomery and Stephen Olson
Question # 4 A cloud engineer is running a latency-sensitive workload that must be resilient and highly available across multiple regions. Which of the following concepts best addresses these requirements? A. CloningB. ClusteringC. Hardware passthroughD. Stand-alone container
Click for Answer
B. Clustering
Answer Description Clustering refers to the use of multiple servers/computers to form what appears to be a single system. This concept is key for achieving high availability and resilience, especially for latency-sensitive workloads. By distributing the workload across a cluster that spans multiple regions, the system can continue to operate even if one or more nodes fail, thus maintaining performance and availability. References: CompTIA Cloud+ Guide to Cloud Computing (ISBN: 978-1-64274-282-2)
Question # 5 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 # 6 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 # 7 An organization has been using an old version of an Apache Log4j software component in its critical software application. Which of the following should the organization use to calculate the severity of the risk from using this component? A. CWEB. CVSSC. CWSSD. CVE
Click for Answer
B. CVSS
Answer Description Explanation:
The Common Vulnerability Scoring System (CVSS) is what the organization should use to calculate the severity of the risk from using an old version of Apache Log4j software component. CVSS provides an open framework for communicating the characteristics and impacts of IT vulnerabilities. References: CompTIA Cloud+ Study Guide (Exam CV0-004) - Chapter on Risk Management
Question # 8 Which of the following is a difference between a SAN and a NAS? A. A SAN works only with fiber-based networks.B. A SAN works with any Ethernet-based network.C. A NAS uses a faster protocol than a SAND. A NAS uses a slower protocol than a SAN.
Click for Answer
D. A NAS uses a slower protocol than a SAN.
Answer Description A NAS (Network Attached Storage) typically uses file-level protocols such as NFS or SMB, which are generally considered slower and less efficient than the block-level protocols used by SANs (Storage Area Networks), such as iSCSI or Fibre Channel. SANs are designed for high performance and low latency, making them more suitable for applications requiring fast and efficient storage access.
