A technician needs to recommend an internet connection for a customer who travels around the world and wants to have connectivity while visiting remote camping locations. Some of the locations the customer visits have limited or unreliable cellular service. Which of the following connection types should the technician recommend?

• A. Satellite
• B. DSL
• C. Fiber
• D. Hotspot

Answer: A

Explanation:
The connection type that the technician should recommend is Satellite. Satellite internet is a good option for people who travel around the world and want to have connectivity while visiting remote camping locations. It works by using terminals which can give you internet access in remote locations as long as they have a line of sight to the satellite in orbit above12.
Since the customer travels to remote camping locations with limited or unreliable cellular service, the best recommendation is satellite internet connection. Satellite internet uses a dish to connect to satellites orbiting the earth, which can provide coverage anywhere in the world as long as there is a clear line of sight to the satellite. This is especially useful in remote areas where traditional terrestrial connections are not available.

NEW QUESTION 5

A company wants to add virtual servers to handle unusually high web traffic usage. Which of the following is the most efficient way?

• A. Community cloud
• B. File synchronization
• C. Rapid elasticity
• D. Cloud VDI

Answer: C

Explanation:
Rapid elasticity is the ability of a cloud service to scale up or down the resources (such as virtual servers, storage, bandwidth, etc.) according to the demand of the users. This is an efficient way to handle unusually high web traffic usage, as it allows the company to provision more virtual servers when needed and release them when not needed, without wasting resources or paying for unused capacity. Rapid elasticity also improves the performance and availability of the web service, as it can adjust to the fluctuations in traffic and avoid overloading or downtime.

NEW QUESTION 7

A new HD webcam's image only updates one or two times per second. The specifications indicate the webcam is capable of updating 30 frames per second. Which of the following is MOST
likely causing the issue?

• A. The USB 2.0 port has insufficient bandwidth.
• B. The Thunderbolt connector is not compatible.
• C. The VGA cable does not support a digital signal.
• D. The connection should — instead of STP.

Answer: A

Explanation:
The USB 2.0 port has insufficient bandwidth to support a high-definition webcam that can update 30 frames per second. USB 2.0 has a maximum theoretical bandwidth of 480 Mbps, which may not be enough for HD video streaming. The user should try using a USB 3.0 port or a Thunderbolt connector, which have higher bandwidths and can support HD webcams. The Thunderbolt connector is compatible with USB devices, so it is not the cause of the issue. The VGA cable and the STP cable are not related to the webcam, as they are used for video output and network connection respectively.

• A. A foreign object Is stuck Inside the port
• B. The cable connection utilized the wrong orientation.
• C. The USB cable is physically damaged.
• D. The USB port belongs to a different form factor.

Answer: D

Explanation:
USB 3.0 ports are slightly smaller than other USB connections, so if the port appears to be the wrong size, it is likely that the port belongs to a different form factor. This can be caused by a number of factors, such as the device being too old to support USB 3.0, or the device not having a USB 3.0 port in the first place.

NEW QUESTION 10

A help desk technician receives a ticket stating a printer has jammed several times today. The technician removes the jammed paper and notices the paper supply is low and the paper in the tray is wrinkled. Which of the following MOST likely caused the paper jams?

• A. High latency
• B. Page orientation
• C. Driver mismatch
• D. Multipage misfeed

Answer: D

Explanation:
A multipage misfeed is when more than one sheet of paper feeds into the printer at once, causing paper jams or misprints. A multipage misfeed can be caused by low paper supply or wrinkled paper in the tray, as reported by the user in this case. High latency is not related to paper jams, but to network delays or slow performance. Page orientation refers to whether the page is printed in portrait or landscape mode, which does not affect paper jams either. Driver mismatch could cause printing errors or compatibility issues, but not paper jams.

• C. 25 (SMTp)
• D. 515 (LDP)
• E. 631 (IPP)
• F. LPTI

Answer: DE

Explanation:
To enable network printing, the firewall needs to open the ports that are used by the network printers and the print servers. Two common ports for network printing are 515 (LDP) and 631 (IPP). LDP stands for Line Printer Daemon Protocol, which is a TCP-based protocol for sending print jobs to a remote printer. IPP stands for Internet Printing Protocol, which is a HTTP-based protocol for managing and monitoring print jobs over the Internet. According to the CompTIA Core1 objectives, one of the network ports that is related to printing is 515. A research paper on network printing also mentions that LDP and IPP are widely used protocols for network printing.

Application virtualization is a technique that allows an application to run on a computer without being installed or affecting other applications on the system. Application virtualization creates a virtual environment for the application that isolates it from the underlying operating system and hardware. This way, the technician can verify the application deployment will not affect other legacy applications on the end users’ computers.

NEW QUESTION 13

An engineer is setting up two-factor authentication so users can access a company's human resources system. Which of the following should the engineer require users to do?

• A. Use a mobile authenticator application.
• B. Connect to the company's Wi-Fi.
• C. Connect through the VPN.
• D. Use a bastion server.

Answer: A

Explanation:
Two-factor authentication (2FA) is a method of verifying a user’s identity by requiring two pieces of evidence: something the user knows (such as a password) and something the user has (such as a device). A mobile authenticator application is a software program that runs on a smartphone or tablet and generates a one-time code or token that the user can enter along with their password to access a system. This adds an extra layer of security to prevent unauthorized access.
