NEW QUESTION # 123
Which of the following ports allows for secure communications?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
Explanation
The correct answer is B. 22.
Port 22 is the default port for SSH (Secure Shell), a protocol that allows secure and encrypted remote login and command execution over a network. SSH uses public key cryptography to authenticate the client and the server, and to encrypt the data exchanged between them. SSH can be accessed through different ports, depending on the configuration of the server and the client. The default port for SSH is 22, but it can be changed to any other port for security reasons1.
Port 20 is the default port for FTP (File Transfer Protocol) data transfer, a protocol that allows file transfer between a client and a server over a network. FTP uses two ports: one for data transfer (port 20) and one for control commands (port 21). FTP does not provide encryption or authentication, and it is vulnerable to various attacks, such as packet sniffing, spoofing, or brute force. To secure FTP connections, protocols such as FTPS (FTP over SSL) or SFTP (SSH File Transfer Protocol) can be used2.
Port 23 is the default port for Telnet, a protocol that allows remote login and command execution over a network. Telnet does not provide encryption or authentication, and it sends data in plain text, which can be easily intercepted or modified by attackers. Telnet is considered obsolete and insecure, and it should be replaced by SSH or other secure protocols3.
Port 25 is the default port for SMTP (Simple Mail Transfer Protocol), a protocol that allows sending and receiving email messages over a network. SMTP does not provide encryption or authentication, and it can be exploited by spammers or hackers to send malicious or unwanted emails. To secure SMTP connections, protocols such as SMTPS (SMTP over SSL) or STARTTLS (Transport Layer Security) can be used.
Therefore, port 22 is the only port that allows for secure communications by default, as it uses SSH protocol.
For more information about ports and their security, you can refer to the following web search results: How to secure your TCP/IP ports, What is an SSL port? A technical guide for HTTPS, HTTPS Port: What It Is, How to Use It, and More (2023).
NEW QUESTION # 124
A technician is creating a new RAID array for a customer After interviewing the customer, the technician decides to implement a RAID array of striping without parity. Which of the following reasons would lead the technician to choose striping without parity instead of striping with parity?
- A. Redundancy and speed are equally important
- B. Available storage space needs to be maximized
- C. Uptime is the customer's biggest concern
- D. Speed is the most important consideration.
Answer: D
Explanation:
Explanation
Speed is the most important consideration. Striping without parity, also known as RAID 0, is a RAID configuration that splits data across multiple disks without any redundancy. This improves the performance of read and write operations, as multiple disks can work in parallel. However, this also increases the risk of data loss, as any disk failure will result in losing all data on the array. Therefore, striping without parity is suitable for situations where speed is prioritized over reliability. According to the CompTIA Core1 objectives, one of the advantages of RAID 0 is increased speed. A research paper on RAID performance also confirms that RAID 0 has the highest throughput among all RAID levels.

- D. Inquire about environmental or infrastructure changes.
Answer: A
Explanation:
Explanation
Once the technician has determined that the power supply is likely to be defective, they should establish a plan of action to resolve the problem. This may include replacing the power supply or further testing to confirm that it is indeed defective. After establishing a plan of action, the technician should implement the solution and verify that it has resolved the issue.
NEW QUESTION # 126

A technician is troubleshooting a projector that will not display any Images. The technician has verified the computer output and cable are providing a good video signal. Which of the following should the technician do NEXT?
- A. Clean the fans.
- B. Test the output resolution.
- C. Calibrate the image.
- D. Replace the bulb.
Answer: B
Explanation:
Explanation
The MOST efficient next step the technician should do is to test the output resolution1. The issue of a projector that will not display any images could be related to the output resolution1. If the output resolution is not compatible with the projector, the projector will not display any images1. Calibrating the image, replacing the bulb, or cleaning the fans may not be effective1.
If a projector is not displaying any images despite verifying that the computer output and cable are providing a good video signal, the technician should test the output resolution. The output resolution of the computer may not be compatible with the projector, which can cause the projector to not display any images.
NEW QUESTION # 128
A cloud engineer, who is designing a cloud architecture, needs to ensure the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization. Which of the following should the engineer Implement? (Select two).
- A. Metered utilization
- B. Elasticity
- C. Cold storage
- D. High availability
- E. Machine learning
- F. Virtualization
Answer: B,D
Explanation:
Explanation
The answer is A. High availability and B. Elasticity.
High availability is the ability of a system to remain operational and accessible with minimal or no downtime, even in the event of failures, disasters, or disruptions. High availability can be achieved by designing a system that has redundancy, fault tolerance, and disaster recovery capabilities. For example, a cloud engineer can design a system that replicates data and resources across multiple regions, zones, or availability domains, and uses load balancing and failover mechanisms to distribute the workload and handle failures gracefully12.
Elasticity is the ability of a system to scale up or down automatically in response to changes in demand or utilization. Elasticity can be achieved by designing a system that can dynamically allocate and deallocate resources based on predefined metrics, policies, or triggers. For example, a cloud engineer can design a system that uses auto-scaling groups, horizontal or vertical scaling strategies, and on-demand or spot instances to optimize the performance and cost of the system32.
By implementing high availability and elasticity, a cloud engineer can ensure that the solution is able to immediately fail over to another region in case of an outage and also scale up in the event of high utilization.
These are two important aspects of building reliable and scalable cloud architectures. Therefore, options A and B are the correct answers.
