NEW QUESTION # 113
Which of the following delivers internet over a copper medium?
- A. SDN
- B. ONT
- C. DSL
- D. WISP
Answer: C
Explanation:
Explanation
The correct answer is C. DSL.
DSL stands for Digital Subscriber Line, which is a technology that delivers internet over a copper medium, such as a telephone line. DSL uses different frequencies than voice calls, so it can provide both internet and phone service simultaneously. DSL can offer faster speeds than dial-up, but it depends on the distance from the service provider and the quality of the copper line .
The other options are not technologies that deliver internet over a copper medium. ONT stands for Optical Network Terminal, which is a device that converts optical signals from a fiber optic cable to electrical signals for a copper cable or a wireless router. ONT is used for fiber-to-the-home (FTTH) internet service, which delivers internet over a fiber optic medium. SDN stands for Software Defined Networking, which is a technology that allows network administrators to manage and control network resources and traffic using software applications. SDN is not related to the physical medium of internet delivery, but rather to the logical layer of network configuration and optimization. WISP stands for Wireless Internet Service Provider, which is a company that delivers internet over a wireless medium, such as radio waves or microwaves. WISP can provide internet access to rural or remote areas where wired connections are not available or feasible.

- A. Sandbox
- B. Hybrid cloud
- C. Production network
- D. Honeypot
Answer: A
Explanation:
Explanation
A sandbox is a virtual environment that allows testing or running applications without affecting the main system. A sandbox can isolate the applications from the rest of the system, preventing any unwanted changes, errors, or security risks. A sandbox can also be easily reset to the initial state, discarding any modifications or data generated by the applications12.
A sandbox is a useful tool for stress testing multiple applications, as it can:
*Simulate different scenarios and conditions for the applications, such as high load, low memory, network latency, etc.
*Monitor and measure the performance, stability, and resource consumption of the applications under stress.
*Compare and analyze the results of different applications or different versions of the same application.
*Identify and fix any bugs, errors, or vulnerabilities in the applications before deploying them to the main system.

- A. Community
- B. Hybrid
- C. Private
- D. Public
Answer: A
Explanation:
A community cloud model is a cloud solution in which infrastructure is shared among organizations that have common interests, goals, or concerns, such as security, compliance, or industry standards. This model would best address the bank's need to leverage cloud computing while maintaining a high level of security and privacy for its data and transactions.

NEW QUESTION # 120
A technician needs to install a cost-effective storage device into a rackmount server that will be used as a VM host. This storage will be used for all VMs that run from the server. Which of the following should be used?
- A. 15,000rpm drive
- B. Optical disk drive
- C. RAID 10 array
- D. eMMC storage device
Answer: C
Explanation:
RAID 10 array is often used for server virtualization as it provides both redundancy and performance benefits. It uses a combination of mirroring and striping to provide both fault tolerance and improved I/O performance. An optical disk drive or eMMC storage device would not provide enough storage or performance for a VM host server, while a 15,000rpm drive may provide good performance but would not provide redundancy for fault tolerance. Therefore, a RAID 10 array is the best option for cost-effective storage that will be used for all VMs that run from the server.

NEW QUESTION # 122
A systems administrator needs to set up a multifunction printer for the legal department. The legal department deals with sensitive documents and requires a secure method of releasing print jobs. Which of the following should the systems administrator configure to meet the department's security requirements?
- A. Audit logging
- B. User authentication
- C. SMB settings
- D. Wired connection
Answer: B
Explanation:
Explanation
This option requires the user to enter a PIN code or swipe a smart card before the printer releases their print job. This way, the user can verify their identity and ensure that no one else can access their sensitive documents.
The other options are not as secure or effective as user authentication. SMB settings are used to share files and printers over a network, but they do not provide a secure method of releasing print jobs. Audit logging records the details of each print job, but it does not prevent unauthorized access to the printed documents. Wired connection reduces the risk of wireless interference or hacking, but it does not guarantee that the print jobs are only retrieved by the intended recipient.

A video game developer is requesting a new desktop computer with eight sticks of memory. The developer wants the desktop computer to take advantage of all available memory bandwidth without sacrificing performance. Which of the following would be the BEST solution?
- A. Quad-channel with DDR5 SODIMM
- B. Dual-channel with DDR4 RAM
- C. Quad-channel with DDR4 RAM
- D. Triple-channel with DDR5 ECC RAM
Answer: C
Explanation:
Explanation
Quad-channel memory architecture allows the CPU to access four memory modules simultaneously, increasing the memory bandwidth and performance. DDR4 RAM is a type of memory that has higher speed and lower power consumption than DDR3. SODIMM is a smaller form factor of memory that is typically used in laptops, not desktops. ECC RAM is a type of memory that can detect and correct errors, but it is more expensive and slower than non-ECC RAM. Triple-channel memory architecture is less common and less efficient than quad-channel. References: https://www.comptia.org/certifications/a#examdetails

NEW QUESTION # 125
A technician is building a video production workstation that will consist of two high-end GPUs The technician is reusing an existing ATX case. Which of the following should the technician select as the MOST appropriate power supply type?
- A. 1.5O0W uninterruptible power supply
- B. 400W external power supply
- C. 2x 600W redundant power supplies
- D. 1.200W modular power supply
Answer: D
Explanation:
Explanation
A video production workstation that will consist of two high-end GPUs will require a lot of power and a modular power supply. A modular power supply allows the technician to connect only the cables that are needed for the components, which reduces clutter and improves airflow. A 1,200W power supply should be enough to power the two GPUs and other components, but the exact wattage depends on the specifications of the GPUs and other components. A 400W external power supply is not enough to power the workstation and may not be compatible with the ATX case. Two 600W redundant power supplies are unnecessary and may not fit in the ATX case. A 1,500W uninterruptible power supply (UPS) is a device that provides backup power in case of a power outage, but it is not a replacement for a power supply unit (PSU). References:
