• A. 22, 53, 445
• B. 22, 443, 445
• C. 25, 123, 443
• D. 137, 139, 445

Answer: B

Explanation:
These are the network ports that are required from a security perspective to copy a large set of files between the private and public cloud through a VPN tunnel. 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. To copy files between the private and public cloud, the following ports are needed:
✑ Port 22: This is the port used by SSH (Secure Shell) protocol, which is a method of remotely accessing and managing cloud resources or systems using a command- line interface. SSH can also be used to securely transfer files using SCP (Secure Copy Protocol) or SFTP (SSH File Transfer Protocol).
✑ Port 443: This is the port used by HTTPS (Hypertext Transfer Protocol Secure), which is a protocol that encrypts and secures web traffic. HTTPS can also be used to transfer files using web browsers or tools such as curl or wget.
✑ Port 445: This is the port used by SMB (Server Message Block) protocol, which is a protocol that allows file sharing and access over a network. SMB can also be used to transfer files using tools such as robocopy or rsync.

NEW QUESTION 5

An enterprise recently upgraded the memory of its on-premises VMs from 8GB to 16GB. However, users are not experiencing any performance benefit. Which of the following is the MOST likely reason?

• A. Insufficient memory on the hypervisor
• B. Operating system memory limit
• C. Memory mismatch error
• D. Dynamic memory allocation

Answer: B

Explanation:
The most likely reason why users are not experiencing any performance benefit after upgrading the memory of their on-premises VMs is that the operating system has a memory limit that prevents it from using more than 8GB of RAM. This could be due to the operating system version, edition, or configuration. The systems administrator should check the operating system settings and requirements and adjust them accordingly to allow the VMs to use the full 16GB of RAM. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 4.0 Troubleshooting, Objective 4.3 Given a scenario, troubleshoot capacity issues within a cloud environment.

NEW QUESTION 6

A company is using a method of tests and upgrades in which a small set of end users are exposed to new services before the majority of other users. Which of the following deployment methods is being used?

• A. Blue-green
• B. Canary
• C. Big bang
• D. Rolling

Answer: B

Explanation:
A canary deployment is a software deployment technique where a new feature or version is released to a small subset of users in production prior to releasing it to a larger subset or all the users. It is also sometimes termed a phased rollout or incremental release1. A canary deployment allows the developers to test the new service in a real environment and get feedback from the users before making it available to everyone. It also reduces the risk of failures and enables easy rollbacks if something goes wrong. A canary deployment is different from a blue-green deployment, where two identical environments are used to switch between the old and new versions of the service. A big bang deployment is where the new service is released to all the users at once, without any testing or gradual rollout. A rolling deployment is where the new service is installed in batches or stages, replacing the old service gradually until all the users are on the new version.

NEW QUESTION 7

A security analyst is investigating incidents in which attackers are able to access sensitive data from a corporate application's database. The attacks occur periodically and usually after the release of a new application's version. The following log confirms the compromise:
<date> USER: WebApp access—key accepted
<date> WebApp user assumed DBA role
<date> GetData API call executed
The following actions are made after every incident occurrence:
• Validation of firewall rules
• Scripted rebuild of the database and web instances
• Application deployment from a cloud code repository
Which of the following actions will MOST likely prevent future compromises?

• A. Rotating the account credentials
• B. Migrating the database to be on premises
• C. Forbidding the use of API calls to retrieve data
• D. Implementing a new database service account

Answer: A

Explanation:
One possible cause for the incidents in which attackers are able to access sensitive data from a corporate application’s database is that the account credentials used by the web application to access the database are compromised or leaked. The log confirms that the attackers are using the WebApp user account to assume the DBA role and execute the GetData API call, which could allow them to retrieve any data from the database. The account credentials could be compromised or leaked due to various reasons, such as weak passwords, phishing attacks, code injection, or insecure storage or transmission. Therefore, one action that will most likely prevent future compromises is to rotate the account credentials, which means changing them periodically or after every incident occurrence. Rotating the account credentials can reduce the risk of unauthorized access by invalidating the old or stolen credentials and enforcing strong and unique passwords for each account.

NEW QUESTION 8

A DevOps administrator is automating an existing software development workflow. The administrator wants to ensure that prior to any new code going into production, tests confirm the new code does not negatively impact existing automation activities.
Which of the following testing techniques would be BEST to use?

• A. Usability testing
• B. Regression testing
• C. Vulnerability testing
• D. Penetration testing

Answer: B

Explanation:
Regression testing is a type of testing that ensures that new code or changes to existing code do not break or degrade the functionality of the software. Regression testing is often used in software development workflows to verify that new features or bug fixes do not introduce new errors or affect the performance of the software. Regression testing can help prevent negative impacts on existing automation activities by checking that the new code is compatible with the existing code and does not cause any unexpected failures or errors.

NEW QUESTION 9

A systems administrator is performing an OS upgrade on a production VM. Which of the following actions should the administrator take before the upgrade to ensure the FASTEST recovery of the system in case the upgrade fails in an unrecoverable way?

• A. Submit the upgrade to the CAB.
• B. Perform a full backup.
• C. Take a snapshot of the system.
• D. Test the upgrade in a preproduction environment.

Answer: C

Explanation:
A snapshot is an image of your system/volume at a specific point in time. It captures the entire file system as it was when the snapshot was taken. When a snapshot is used to restore the system, the system will revert to exactly how it was at the time of the snapshot1. Snapshots are designed for short-term storage and fast recovery. They do not need a lot of storage space or time to create copies234.
Taking a snapshot of the system before the OS upgrade would ensure the fastest recovery of the system in case the upgrade fails in an unrecoverable way. The administrator could simply restore the system from the snapshot and avoid any data loss or corruption. This would be much faster and easier than performing a full backup or testing the upgrade in a preproduction environment.

NEW QUESTION 10

A VDI provider suspects users are installing prohibited software on the instances. Which of the following must be implemented to prevent the issue?

• A. Log monitoring
• B. Patch management
• C. Vulnerability scanning
• D. System hardening

Answer: D

Explanation:
System hardening is the process of securing a system by reducing its attack surface and eliminating unnecessary services, features, or functions. System hardening can help prevent users from installing prohibited software on the VDI instances by applying policies and restrictions that limit the user privileges and access rights. For example, system hardening can disable the installation of software from unknown sources, enforce the use of strong passwords, enable encryption, and remove default accounts. System hardening can also improve the performance and stability of the VDI instances by removing
unwanted or unused components. References: [CompTIA Cloud+ CV0-003 Certification Study Guide], Chapter 9, Objective 9.1: Given a scenario, apply security controls and techniques.

NEW QUESTION 11

A cloud administrator has deployed several VM instances that are running the same applications on VDI nodes. Users are reporting that a role instance is looping between STARTED, INITIALIZING, BUSY, and stop. Upon investigation, the cloud administrator can see the status changing every few minutes. Which of the following should be done to resolve the issue?

• A. Reboot the hypervisor.
• B. Review the package and configuration file.
• C. Configure service healing.
• D. Disable memory swap.

Answer: B

Explanation:
The best way to resolve the issue where a role instance is looping between STARTED, INITIALIZING, BUSY, and STOP after deploying several VM instances that are running the same applications on VDI nodes is to review the package and configuration file. The package and configuration file are the components that define the application and its settings for the VM instances. The package contains the application code, binaries, and dependencies, while the configuration file contains the parameters, values, and settings for the application. Reviewing these components can help identify and fix any errors or inconsistencies that may cause the role instance to loop or fail.

NEW QUESTION 13

A systems administrator audits a cloud application and discovers one of the key regulatory requirements has not been addressed. The requirement states that if a physical breach occurs and hard drives are stolen, the contents of the drives should not be readable. Which of the following should be used to address the requirement?

• A. Obfuscation
• B. Encryption
• C. EDR
• D. HIPS

Answer: B

Explanation:
Encryption is the process of transforming data into an unreadable format using a secret key or algorithm. Encryption can be used to protect data at rest or in transit from unauthorized access or theft. If a physical breach occurs and hard drives are stolen, encryption can prevent the contents of the drives from being readable by anyone who does not have the decryption key or algorithm.

NEW QUESTION 14

A systems administrator is configuring RAID for a new server. This server will host files for users and replicate to an identical server. While redundancy is necessary, the most important need is to maximize storage.
Which of the following RAID types should the administrator choose?

• A. 5
• B. 6
• C. 10
• D. 50

Answer: C

Explanation:
RAID 50 is a type of RAID level that combines RAID 5 and RAID 0 to create a nested RAID configuration. RAID 50 consists of two or more RAID 5 arrays that are striped together using RAID 0. RAID 50 can provide redundancy, fault tolerance, and high performance for large data sets. RAID 50 can also maximize storage, as it has a higher usable capacity than other RAID levels with similar features, such as RAID 6 or RAID 10. The administrator should choose RAID 50 to configure a new server that will host files for users and replicate to an identical server, as it can meet the needs of redundancy and storage maximization. References: CompTIA Cloud+ Certification Exam Objectives, page 9, section 1.4

NEW QUESTION 15

A cloud administrator configured a local cloud-resource pool lo offer 64GB of memory, 64 cores, and 640GB of storage. Thirty-two machines with identical resource allocations are started. but one machine is unable to handle requests. Which of the following is the MOST likely cause?

• A. Insufficient guest bandwidth
• B. Overwhelmed vCPU
• C. A storage error on the guest
• D. Incorrect VLAN assignment
• E. Inadequate memory allocation

Answer: B

Explanation:
The most likely cause of one machine being unable to handle requests after deploying a new three-host cluster with identical resource allocations is that it has an overwhelmed vCPU (virtual CPU). An overwhelmed vCPU means that there is more demand for CPU resources than what is available on the host or VM. This could result in poor performance, high latency, or errors for the applications or processes that run on that machine. The systems administrator should monitor the CPU utilization and load on each
machine and adjust them accordingly to balance the workload. Reference: [CompTIA Cloud+ Certification Exam Objectives], Domain 4.0 Troubleshooting, Objective 4.3 Given a scenario, troubleshoot capacity issues within a cloud environment.

NEW QUESTION 16

A systems administrator is about to deploy a new VM to a cloud environment. Which of the following will the administrator MOST likely use to select an address for the VM?

• A. CDN
• B. DNS
• C. NTP
• D. IPAM

Answer: D

Explanation:
IPAM (IP Address Management) is what the administrator will most likely use to select an address for the new VM that is about to be deployed to a cloud environment. IPAM is a tool or service that allows customers to plan, track, and manage the IP addresses and DNS names of their cloud resources or systems. IPAM can help to select an address for the new VM by providing information such as available IP addresses, IP address ranges, subnets, domains, etc., as well as ensuring that the address is unique and valid.

NEW QUESTION 17

A systems administrator is informed that a database server containing PHI and PII is unencrypted. The environment does not support VM encryption, nor does it have a key management system. The server needs to be able to be rebooted for patching without manual intervention.
Which of the following will BEST resolve this issue?

• A. Ensure all database queries are encrypted
• B. Create an IPSec tunnel between the database server and its clients
• C. Enable protocol encryption between the storage and the hypervisor
• D. Enable volume encryption on the storage
• E. Enable OS encryption

Answer: D

Explanation:
Volume encryption is a type of encryption that protects data at the storage level by encrypting an entire disk or partition. Volume encryption can provide strong security for data at rest, as it prevents unauthorized access to the data even if the storage device is lost, stolen, or compromised. Volume encryption can also support automatic booting without manual intervention, as it can use a pre-boot authentication mechanism that does not require user input. Enabling volume encryption on the storage is the best way to resolve the issue of having an unencrypted database server containing PHI and PII, as it can protect the sensitive data without relying on VM encryption or a key management
system. References: CompTIA Cloud+ Certification Exam Objectives, page 14, section 2.7

NEW QUESTION 18

A DevOps team needs to provide a solution that offers isolation, portability, and scalability Which of the following would BEST meet these requirements?

• A. Virtual machines
• B. Containers
• C. Appliances
• D. Clusters

Answer: B

Explanation:
Containers are a solution that offers isolation, portability, and scalability for software development and deployment. Containers are lightweight and self-contained units of software that package up the application code and all its dependencies, such as libraries, frameworks, and configuration files. Containers run on a container platform, such as Docker or Kubernetes, that provides the runtime environment and orchestration for the containers.
Containers offer isolation, as they run independently from each other and from the underlying host system. Each container has its own namespace, filesystem, network, and resources, and does not interfere with other containers or processes. Containers also offer portability, as they can run on any system that supports the container platform, regardless of the hardware or operating system differences. Containers can be easily moved, copied, or deployed across different environments, such as development, testing, or production. Containers also offer scalability, as they can be dynamically created, destroyed, or replicated to meet the changing demand for the application. Containers can also leverage the distributed computing power of clusters, which are groups of servers that work together to provide high availability and performance .
