After a user connects a laptop to a newly purchased printer, the user is unable to print. Which of the following is most likely causing the issue?
Answer : C
Which of the following contains reusable code?
Answer : C
Which of the following best practices can be used to mitigate password reuse?
Answer : D
Password history is a best practice that helps mitigate password reuse by preventing users from reusing previous passwords. This policy ensures that users must choose new, unique passwords after each reset, enhancing security by reducing the risk of password recycling.
A . Password length makes the password harder to guess but doesn't prevent reuse.
B . Password complexity ensures the password is harder to crack but also doesn't prevent reuse.
C . Password reset is the process of changing a password but doesn't control reuse unless combined with password history policies.

A user clicks a link to a web page to view a document, but nothing happens. Which of the following is most likely the issue?
Answer : A
If a user clicks a link to view a document on a web page and nothing happens, the most likely cause is that scripting is disabled. Many web pages use JavaScript or other scripting languages to execute functions such as opening documents, redirecting to other pages, or displaying dynamic content. If scripting is turned off in the browser's settings, these actions will not work.
B . The security settings are too high could block certain actions, but scripting being disabled is a more common cause.
C . Pop-up blockers could prevent new windows from opening, but typically wouldn't affect document viewing.
D . An invalid web certificate would prevent access to the entire site, not just a specific action like opening a document.

A building has two legacy APs. A new AP was recently installed within 30ft (9m) of the legacy APs. Multiple users have been reporting intermittent internet connectivity since the new AP was installed. Which of the following explains what is happening?
Answer : B
The intermittent internet connectivity experienced by users since the installation of the new AP is likely due to interference and attenuation. When wireless access points are placed too closely together (in this case, within 30 feet), they can cause interference, especially if they are operating on overlapping channels. Attenuation refers to the weakening of wireless signals as they travel through obstacles or over distance.
A . WEP is enabled is related to security and is unlikely to cause connectivity issues.
C . There are speed limitations would cause slow performance, not intermittent connectivity.
D . The passwords are not synced would result in connectivity denial, not intermittent access.

Which of the following is the least expensive way for users at a large company to load a 2GB spreadsheet quickly?
Answer : D
Adding more RAM to each workstation is the least expensive and most effective way to improve the performance of loading large files like a 2GB spreadsheet. RAM directly impacts how much data a workstation can hold in memory for fast access, and increasing it will help the spreadsheet load and process more quickly. Other options, like upgrading switches or moving to a shared database, may be more costly or less effective.
A . Buy faster networking switches may improve network speed but does not directly affect the local file processing speed.
B . Upgrade the operating system and applications may help, but adding RAM is typically a more cost-effective solution.
C . Move the file to a shared database is unnecessary for a single spreadsheet file.

An engineer has been assigned the task of establishing network connectivity in a remote area where telephone lines are readily available but other infrastructure is limited. Which of the following technologies would be the best solution?
Answer : D
DSL (Digital Subscriber Line) is the best solution when telephone lines are available in a remote area but other network infrastructures, like cable or fiber, are limited. DSL uses existing telephone lines to provide internet access and is often a cost-effective solution in areas with limited connectivity options.
A . Cable requires coaxial infrastructure, which may not be available.
B . Fiber optic provides high-speed connectivity but requires specialized infrastructure.
C . Wireless network may be an option, but DSL is a better fit given the availability of telephone lines.
