NEW QUESTION # 232
A company would like to move all its on-premises platforms to the cloud. The company has enough skilled Linux and web-server engineers but only a couple of skilled database administrators. It also has little expertise in managing email services. Which of the following solutions would BEST match the skill sets of available personnel?
- A. Run the web servers, databases, and email in laaS.
- B. Run the web servers in PaaS, and run the databases and email in SaaS.
- C. Run the web servers in laaS, the databases in PaaS, and the email in SaaS.
- D. Run the web servers, databases, and email in SaaS.
Answer: C
Explanation:
Explanation
To answer this question, we need to understand the different types of cloud computing models and how they suit the skill sets of the available personnel. According to Google Cloud, there are three main models for cloud computing: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each model provides different levels of control, flexibility, and management over the cloud resources and services1.
IaaS: This model provides access to networking features, computers (virtual or on dedicated hardware), and data storage space. It gives the highest level of flexibility and management control over the IT resources and is most similar to existing IT resources that many IT departments and developers are familiar with2.
PaaS: This model provides a complete cloud platform for developing, running, and managing applications without the cost, complexity, and inflexibility of building and maintaining the underlying infrastructure. It removes the need for organizations to manage the hardware and operating systems and allows them to focus on the deployment and management of their applications2.
SaaS: This model provides a completed product that is run and managed by the service provider. It does not require any installation, maintenance, or configuration by the customers. It is typically used for end-user applications that are accessed through a web browser or a mobile app2.
Based on these definitions, we can evaluate each option:
Option A: Run the web servers in PaaS, and run the databases and email in SaaS. This option is not the best match for the skill sets of the available personnel because it does not leverage their expertise in Linux and web-server engineering. Running the web servers in PaaS means that they will have less control and customization over the web server environment and will have to rely on the service provider's platform features. Running the databases and email in SaaS means that they will not need any database administration or email management skills, but they will also have less flexibility and security over their data and communication.
Option B: Run the web servers, databases, and email in SaaS. This option is not a good match for the skill sets of the available personnel because it does not utilize their skills at all. Running everything in SaaS means that they will have no control or responsibility over any aspect of their cloud environment and will have to depend entirely on the service provider's products. This option may be suitable for some small businesses or non-technical users who do not have any IT skills or resources, but not for a company that has skilled Linux and web-server engineers.
Option C: Run the web servers in IaaS, the databases in PaaS, and the email in SaaS. This option is the best match for the skill sets of the available personnel because it balances their strengths and weaknesses. Running the web servers in IaaS means that they can use their Linux and web-server engineering skills to configure, manage, and optimize their web server infrastructure according to their needs. Running the databases in PaaS means that they can leverage the service provider's platform features to simplify their database development and administration tasks without having to worry about the underlying hardware and operating systems. Running the email in SaaS means that they can outsource their email services to a reliable and secure service provider without having to invest in or manage their own email infrastructure.
Option D: Run the web servers, databases, and email in IaaS. This option is not a good match for the skill sets of the available personnel because it puts too much burden on them. Running everything in IaaS means that they will have to handle all aspects of their cloud environment, including networking, computing, storage, security, backup, scaling, patching, etc. This option may be suitable for some large enterprises or highly technical users who have full control and customization over their cloud environment, but not for a company that has only a couple of skilled database administrators and little expertise in managing email services.
Therefore, option C is the correct answer.

NEW QUESTION # 236
Based on the shared responsibility model, which of the following solutions passes the responsibility of patching the OS to the customer?
- A. DBaaS
- B. laaS
- C. PaaS
- D. SaaS
Answer: B
Explanation:
IaaS stands for Infrastructure as a Service, and it is a cloud service model that provides customers with access to virtualized computing resources, such as servers, storage, and networks. In the IaaS model, the customer is responsible for patching the operating system (OS) of the virtual machines, as well as installing and managing the applications and dat a. The cloud service provider (CSP) is responsible for maintaining the physical infrastructure, such as the hardware, power, cooling, and security. Therefore, IaaS passes the responsibility of patching the OS to the customer, unlike PaaS, DBaaS, or SaaS, where the CSP handles the OS patching and updates. Reference: CompTIA Cloud+ CV0-003 Certification Study Guide, Chapter 2, Objective 2.1: Given a scenario, deploy cloud services and solutions.

NEW QUESTION # 239
A private IaaS administrator is receiving reports that all newly provisioned Linux VMs are running an earlier version of the OS than they should be. The administrator reviews the automation scripts to troubleshoot the issue and determines the scripts ran successfully. Which of the following is the MOST likely cause of the issue?
- A. Wrong template selection
- B. Incorrect provisioning script indentation
- C. API version incompatibility
- D. Misconfigured script account
Answer: A
Explanation:
Explanation
The wrong template selection is the most likely cause of the issue of newly provisioned Linux VMs running an earlier version of OS than they should be in a private IaaS environment. A template is a preconfigured image or blueprint of a VM that contains an OS, applications, settings, etc., that can be used to create new VMs quickly and consistently. A template may have different versions or updates depending on when it was created or modified. If a template is selected incorrectly or not updated properly, it may result in creating VMs with an older or different version of OS than expected.

NEW QUESTION # 243
A systems administrator has been notified of possible illegal activities taking place on the network and has been directed to ensure any relevant emails are preserved for court use.
Which of the following is this MOST likely an example of?
- A. Version control
- B. Legal hold
- C. File integrity monitoring
- D. Email archiving
Answer: B
Explanation:
Explanation
The correct answer is C. Legal hold.
A legal hold is a process that organizations use to preserve relevant electronic information when they anticipate litigation or have an active e-discovery request. A legal hold requires that certain email messages be retained and unaltered until they are no longer required for court use. Legal hold requirements apply both to the content of messages as well as the metadata which can provide proof of delivery and other critical non-repudiation information12.
Email archiving is a process that organizations use to store email messages for long-term retention, compliance, and backup purposes. Email archiving does not necessarily imply that the email messages are preserved for legal purposes, although some email archiving solutions may offer legal hold capabilities1.
Version control is a process that software developers use to manage changes to source code and other files in a project. Version control allows developers to track, compare, and revert changes, as well as collaborate with other developers. Version control does not apply to email messages or legal hold.
File integrity monitoring is a process that security professionals use to detect unauthorized or malicious changes to files and directories on a system. File integrity monitoring helps to protect the system from malware, data breaches, and configuration errors. File integrity monitoring does not apply to email messages or legal hold.
NEW QUESTION # 244
A cloud engineer is troubleshooting RSA key-based authentication from a local computer to a cloud-based server, which is running SSH service on a default port. The following file permissions are set on the authorized keys file:
-rw-rw-rw-1 ubuntu ubuntu 391 Mar S 01:36 authorized _ keys
Which Of the following security practices are the required actions the engineer Should take to gain access to the server? (Select TWO).
- A. Open port 21 access for the computer's public IP address.
- B. Open port 21 access for 0.0.0.0/0 CIDR.
- C. Fix the file permissions with read-only access to the owner Of the file.
- D. Fix the file permissions with execute permissions to the owner of the file.
- E. Open port 22 access for the computer's public IP address.
- F. open port 22 access for 0.0.0.0/0 CIDR.
Answer: C,E
Explanation:
The correct answer is C and D.
C) Fix the file permissions with read-only access to the owner of the file.
D) Open port 22 access for the computer's public IP address.
The authorized_keys file on the server should have read-only access for the owner of the file, and no access for anyone else. This ensures that only the owner can read the public keys that are authorized to log in, and no one can modify or delete them. The file permissions can be fixed with the command chmod 400 ~/.ssh/authorized_keys on the server. This is a recommended security practice for SSH key-based authentication123.
The computer that wants to log in to the server using SSH key-based authentication needs to have access to port 22 on the server, which is the default port for SSH service. This can be done by opening port 22 access for the computer's public IP address on the server's firewall or security group settings. This allows the computer to initiate an SSH connection to the server and authenticate with its private key. Opening port 21, which is used for FTP service, is not relevant or secure for SSH key-based authentication1.
NEW QUESTION # 245
A financial industry services firm was the victim of an internal data breach, and the perpetrator was a member of the company's development team. During the investigation, one of the security administrators accidentally deleted the perpetrator's user data. Even though the data is recoverable, which of the following has been violated?
- A. Chain of custody
- B. Evidence acquisition
- C. Root cause analysis
- D. Containment
Answer: A
Explanation:
Explanation
The chain of custody is a process that documents and preserves the integrity and authenticity of evidence from the time it is collected until it is presented in court. The chain of custody includes information such as who collected, handled, stored, or transferred the evidence, when and where it was done, and how it was done. By accidentally deleting the perpetrator's user data, the security administrator has violated the chain of custody, as the evidence has been altered or destroyed and can no longer be used in court. 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.
NEW QUESTION # 246
An OS administrator is reporting slow storage throughput on a few VMs in a private IaaS cloud.
Performance graphs on the host show no increase in CPU or memory. However, performance graphs on the storage show a decrease of throughput in both IOPS and MBps but not much increase in latency. There is no increase in workload, and latency is stable on the NFS storage arrays that are used by those VMs.
Which of the following should be verified NEXT?
- A. Application
- B. Network
- C. VM GPU settings
- D. SAN
Answer: B
NEW QUESTION # 247
A systems administrator is troubleshooting issues with network slowness. Traffic analysis shows that uplink bandwidth on the core switch is often sustained at 125Mbps due to a combination of production traffic from other sources. Which of the following would BEST resolve the issue?
- A. Reboot the core switch.
- B. Increase the buffer size on the core switch.
- C. Enable QoS to prioritize production traffic.
- D. Turn off the servers that use the most bandwidth.
Answer: C
Explanation:
The best solution to resolve the issue of network slowness caused by high uplink bandwidth utilization on the core switch is to enable quality of service (QoS) to prioritize production traffic over other types of traffic. QoS is a mechanism that allows network administrators to classify and manage network traffic according to its importance, latency, bandwidth, and reliability requirements. By enabling QoS, the core switch can allocate more resources and guarantee better performance for production traffic, while limiting or dropping less critical traffic. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 4.0 Troubleshooting, Objective 4.1 Given a scenario, troubleshoot connectivity issues related to cloud implementations.
NEW QUESTION # 248
A company needs to access the cloud administration console using its corporate identity. Which of the following actions would MOST likely meet the requirements?
- A. Implement client-based certificate authentication.
- B. Implement SSH key-based authentication.
- C. Implement cloud authentication with local LDAP.
- D. Implement multifactor authentication.
Answer: A
Explanation:
Explanation
Implementing client-based certificate authentication is what the administrator should do to access the cloud administration console using corporate identity. Client-based certificate authentication is a method of verifying and authenticating users or devices based on digital certificates issued by a trusted authority. Digital certificates are electronic documents that contain information such as identity, public key, expiration date, etc., that can be used to prove one's identity and establish secure communication over a network. Client-based certificate authentication can allow users or devices to access cloud resources or services using their corporate identity without requiring passwords or other credentials.
NEW QUESTION # 249

NEW QUESTION # 250
A company that utilizes an IaaS service provider has contracted with a vendor to perform a penetration test on its environment. The vendor is able to exploit the virtualization layer and obtain access to other instances within the cloud provider's environment that do not belong to the company.
Which of the following BEST describes this attack?
- A. Heap spraying
- B. Directory traversal
- C. Buffer overflow
- D. VM escape
Answer: D
Explanation:
VM escape is a type of attack that allows an attacker to break out of a virtual machine (VM) and access the host system or other VMs within the same cloud provider's environment. VM escape can exploit the vulnerabilities in the virtualization layer or hypervisor that separates and isolates the VMs from each other and from the host system. VM escape can result in serious consequences, such as compromising the security and privacy of other customers' data or resources, gaining unauthorized access to the cloud provider's infrastructure or services, or launching further attacks on other systems or networks. VM escape best describes the attack that was performed by a vendor who was able to exploit the virtualization layer and obtain access to other instances within the cloud provider's environment that do not belong to the company. Reference: CompTIA Cloud+ Certification Exam Objectives, page 19, section 4.1
NEW QUESTION # 251
An organization provides integration services for finance companies that use web services. A new company that sends and receives more than 100,000 transactions per second has been integrated using the web service. The other integrated companies are now reporting slowness with regard to the integration service. Which of the following is the cause of the issue?
- A. Incorrect configuration in the authentication process
- B. Incorrect configuration in user access permissions
- C. Incorrect configuration in the SAN storage pool
- D. Incorrect configuration in the message queue length
Answer: D
Explanation:
The correct answer is B. Incorrect configuration in the message queue length.
A message queue is a data structure that stores messages or requests that are sent and received by web services. A message queue allows asynchronous communication between web services, as it decouples the sender and the receiver, and enables them to process messages at different rates. A message queue also provides reliability, scalability, and load balancing for web services, as it ensures that messages are not lost, duplicated, or corrupted, and that they are distributed evenly among the available servers .
However, a message queue also has a limit on how many messages it can store at a time. This limit is determined by the configuration of the message queue length, which is the maximum number of messages that can be in the queue before it becomes full. If the message queue length is too short, the queue may fill up quickly and reject new messages, causing errors or delays in communication. If the message queue length is too long, the queue may consume too much memory or disk space, affecting the performance or availability of the web service .
Therefore, if an organization provides integration services for finance companies that use web services, and a new company that sends and receives more than 100,000 transactions per second has been integrated using the web service, the most likely cause of the issue is an incorrect configuration in the message queue length. The new company may have generated a large volume of messages that exceeded the capacity of the message queue, resulting in slowness for the other integrated companies. The organization should adjust the message queue length to accommodate the increased traffic and optimize the resource utilization of the web service.
NEW QUESTION # 252
