Question 132:
Which of the following actions should a systems administrator perform during the containment phase of a security incident in the cloud?
A. Deploy a new instance using a known-good base image.
B. Configure a firewall rule to block the traffic on the affected instance.
C. Perform a forensic analysis of the affected instance.
D. Conduct a tabletop exercise involving developers and systems administrators.
Correct Answer: B
Configuring a firewall rule to block the traffic on the affected instance is what the administrator should perform during the containment phase of a security incident in the cloud. A security incident is an event or situation that affects or may affect the confidentiality, integrity, or availability of cloud resources or data. A security incident response is a process of managing and resolving a security incident using various phases, such as identification, containment, eradication, recovery, etc. The containment phase is where the administrator tries to isolate and prevent the spread or escalation of the security incident. Configuring a firewall rule to block the traffic on the affected instance can help to contain a security incident by cutting off any communication or interaction between the instance and other systems or networks, which may stop any malicious or unauthorized activity or access.
Question 133:
A systems administrator is planning a penetration test for company resources that are hosted in a public cloud. Which of the following must the systems administrator do FIRST?
A. Consult the law for the country where the company's headquarters is located
B. Consult the regulatory requirements for the company's industry
C. Consult the law for the country where the cloud services provider is located
D. Consult the cloud services provider's policies and guidelines
Correct Answer: D
The first thing that the systems administrator must do before planning a penetration test for company resources that are hosted in a public cloud is to consult the cloud services provider's policies and guidelines. Penetration testing is a type of security assessment that involves simulating an attack on a system or network to identify vulnerabilities and weaknesses. However, not all cloud services providers allow penetration testing on their platforms, or they may have specific rules and requirements for conducting such tests. The systems administrator should check the cloud services provider's policies and guidelines and obtain their permission and approval before performing any penetration testing. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 2.0 Security, Objective 2.4 Given a scenario, implement security automation and orchestration in a cloud environment.

After a few new web servers were deployed, the storage team began receiving incidents in their queue about the web servers. The storage administrator wants to verify the incident tickets that should have gone to the web server team. Which of the following is the MOST likely cause of the issue?
A. Incorrect assignment group in service management
B. Incorrect IP address configuration
C. Incorrect syslog configuration on the web servers
D. Incorrect SNMP settings
Correct Answer: C
Incorrect syslog configuration on the web servers is the most likely cause of the issue of storage team receiving incidents in their queue about web servers after new web servers were deployed in a cloud environment. Syslog is a standard protocol that allows network devices and systems to send log messages to a centralized server or collector. Syslog can help to consolidate and manage logs from different sources in one place, which can facilitate monitoring, analysis, troubleshooting, auditing, etc. Incorrect syslog configuration on the web servers can cause them to send log messages to the wrong destination or queue, such as the storage team's queue, rather than the web server team's queue.
Question 136:
All of a company's servers are currently hosted in one cloud MSP. The company created a new cloud environment with a different MSP. A cloud engineer is now tasked with preparing for server migrations and establishing connectivity between clouds. Which of the following should the engineer perform FIRST?
A. Peer all the networks from each cloud environment.
B. Migrate the servers.
C. Create a VPN tunnel.
D. Configure network access control lists.
Correct Answer: C
Creating a VPN tunnel is the first action that the engineer should perform to prepare for server migrations and establish connectivity between clouds. A VPN (Virtual Private Network) tunnel is a secure and encrypted connection that allows data to be transferred between two networks or locations over the public internet. Creating a VPN tunnel can enable communication and interoperability between different cloud environments, as well as protect data from interception or modification during migration.
Question 137:
An administrator recently provisioned a file server in the cloud. Based on financial considerations, the administrator has a limited amount of disk space. Which of the following will help control the amount of space that is being used?
A. Thick provisioning
B. Software-defined storage
C. User quotas
D. Network file system
Correct Answer: C
User quotas are what will help control the amount of space that is being used by a file server in the cloud that has a limited amount of disk space due to financial considerations. User quotas are the limits or restrictions that are imposed on the amount of space that each user can use or consume on a file server or storage device. User quotas can help to control the amount of space that is being used by: Preventing or reducing wastage or overuse of space by users who may store unnecessary or redundant files or data on the file server or storage device. Ensuring fair and equal distribution or allocation of space among users who may have different needs or demands for space on the file server or storage device. Monitoring and managing the usage or consumption of space by users who may need to be notified or alerted when they reach or exceed their quota on the file server or storage device.
Question 138:
A cloud administrator is upgrading a cloud environment and needs to update the automation script to use a new feature from the cloud provider. After executing the script, the deployment fails. Which of the following is the MOST likely cause?
A. API incompatibility
B. Location changes
C. Account permissions
D. Network failure
Correct Answer: A
API incompatibility is the most likely cause of the failure of an automation script to use a new feature from the cloud provider. API (Application Programming Interface) is a set of rules or specifications that defines how different software components or systems can communicate and interact with each other. API incompatibility is a situation where an API does not work or function properly with another software component or system due to differences or changes in versions, formats, parameters, etc. API incompatibility can cause errors or issues when using an automation script to deploy or configure cloud resources or services, especially if the script is not updated or modified according to the new API specifications.
Question 139:
A systems administrator is troubleshooting a performance issue with a virtual database server. The administrator has identified the issue as being disk related and believes the cause is a lack of IOPS on the existing spinning disk storage. Which of the following should the administrator do NEXT to resolve this issue?
A. Upgrade the virtual database server.
B. Move the virtual machine to flash storage and test again.
C. Check if other machines on the same storage are having issues.
D. Document the findings and place them in a shared knowledge base.
Correct Answer: B
Moving the virtual machine to flash storage and testing again is what the administrator should do next to resolve the issue of disk-related performance issue with a virtual database server that has been identified as being caused by a lack of IOPS on the existing spinning disk storage. IOPS (Input/Output Operations Per Second) is a measure of how fast a storage device can read and write data. IOPS can affect performance of a virtual database server by determining how quickly it can access and process data from storage. Spinning disk storage is a type of storage device that uses rotating magnetic disks to store data. Spinning disk storage has lower IOPS than flash storage, which is a type of storage device that uses solid-state memory chips to store data. Flash storage has higher IOPS than spinning disk storage, which means that it can read and write data faster and more efficiently than spinning disk storage. Moving the virtual machine to flash storage and testing again can help to resolve the issue by increasing the IOPS and improving the performance of the virtual database server.
Question 140:
A systems administrator adds servers to a round-robin, load-balanced pool, and then starts receiving reports of the website being intermittently unavailable. Which of the following is the MOST likely cause of the issue?
A. The network is being saturated.
B. The load balancer is being overwhelmed.
C. New web nodes are not operational.
D. The API version is incompatible.
E. There are time synchronization issues.
Correct Answer: C
New web nodes are not operational is the most likely cause of the issue of website being intermittently unavailable after adding servers to a round-robin, load- balanced pool. A round-robin, load-balanced pool is a method of distributing network traffic evenly and sequentially among multiple servers or nodes that provide the same service or function. A round-robin, load-balanced pool can help to improve performance, availability, and scalability of network applications or services by ensuring that no server or node is overloaded or underutilized. New web nodes are not operational if they are not configured properly or functioning correctly to provide web service or function. New web nodes are not operational can cause website being intermittently unavailable by disrupting the round- robin, load-balanced pool and creating inconsistency or unreliability in web service or function.
