A customer wants to buy a new laptop with a 2.5Gbps processor. Which of the following best describes the device the salesperson should suggest?
Answer : D
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.

A technician is installing an MFD. After installation, all functions work except faxing. Which of the following interfaces is required to enable faxing functionality?
Answer : A
RJ11 is the standard interface for telephone lines and is required for faxing functionality. Most multifunction devices (MFDs) that support faxing need to be connected to a phone line via an RJ11 connection to transmit and receive faxes.
B . RJ45 is used for Ethernet connections, not for faxing.
C . USB is used for connecting peripherals but does not support faxing.
D . Bluetooth is a wireless technology, not typically used for fax functionality.

A script is designed to save the results of user input from a survey to a database table. Which of the following database access methods is used to add the survey data to the table?
Answer : D
Programmatic access refers to the use of scripts or code to interact with a database and manipulate data. In this case, the script is designed to save user input from a survey to a database table, which requires programmatically inserting the data into the table through SQL commands or other database APIs.
A . Direct access refers to low-level access to the database, typically not involving scripts.
B . Query builder is a tool to create queries but does not involve script-based interactions.
C . User interface refers to interacting with the database through graphical or form-based interfaces.
