A systems administrator is working to ensure access to corporate laptops is limited to authorized users. The administrator has already implemented a password policy. Which of the following would be the best option to help the administrator secure the corporate resources?
- A. Encryption
- B. Trusted Platform Module
- C. Laptop lock
- D. Biometric scanner
正解：D
解説：
Explanation
The best option to help the administrator secure the corporate resources is B. Biometric scanner.
A biometric scanner is a device that can authenticate a user's identity based on their physical or behavioral characteristics, such as fingerprint, iris, face, voice, or signature. A biometric scanner can provide a high level of security and convenience for accessing corporate laptops, as it can prevent unauthorized users from accessing the devices and eliminate the need to remember passwords .
The other options are not the best options for this scenario. A Trusted Platform Module (TPM) is a chip that can store encryption keys and other sensitive data on a laptop. A TPM can enhance the security of data and devices, but it does not limit access to authorized users by itself. A TPM can work with a password or a biometric scanner to provide multifactor authentication . A laptop lock is a device that can physically secure a laptop to a desk or other object using a cable and a lock. A laptop lock can deter theft or tampering, but it does not prevent unauthorized users from accessing the laptop if they have the password or the key. Encryption is a process that can protect data on a laptop by transforming it into an unreadable format using a key. Encryption can prevent unauthorized users from accessing or modifying the data, but it does not prevent them from accessing the laptop itself.

質問 # 268
A laser printer is making humming and grinding noises, and the printouts have ghost images on the pages. Which of the following should be replaced?
- A. Paper
- B. Fuser
- C. Cartridge
- D. Rollers
正解：B
解説：
The most likely answer is C. Fuser.
A fuser is a component in a laser printer that uses heat and pressure to fuse the toner powder onto the paper. If the fuser is damaged or worn out, it can cause humming and grinding noises, as well as ghost images on the printouts. Ghost images are faint copies of previous images that appear on the same page. They are caused by the fuser not heating the toner properly, or by the toner sticking to the fuser roller and transferring to the next page12.
To fix this problem, you should replace the fuser unit with a new one. You can check your printer manual for instructions on how to remove and install the fuser unit. You can also use a diagnostic ruler to measure the distance between the ghost images and determine if the fuser is the source of the problem2. If the ghost images are far apart (between 4cm and 5cm), then the fuser is likely to be faulty.

The technician is unable to access the company portal website, but other websites work fine. This suggests an issue with resolving the specific URL of the company portal, which is a function of DNS.
Here's why other options are not the most likely cause:
DHCP reservations: This is not relevant as the issue persists even when the technician tries a different workstation, indicating a problem beyond individual device configuration.
Static IP addresses: Similar to DHCP reservations, static IPs are not likely the cause as both affected workstations are experiencing the issue.
Default gateway: While the default gateway is necessary for internet access, other websites are working, making it less likely to be the root cause.

Which of the following delivers internet over a copper medium?
- A. ONT
- B. SDN
- C. DSL
- D. WISP
正解：C
解説：
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.
質問 # 277
After an IT department implements SSL redirection, users report being unable to access a random number generator opened within a web browser.
Which of the following should a technician do first to troubleshoot this issue?
- A. Check to see whether the website is HTTPS enabled.
- B. Report the affected user accounts to the IT department.
- C. Reset the web browser cache.
- D. Ensure that the computer supports secure socket communication.
正解：A
解説：
The first step to troubleshoot this issue is to check if the website that hosts the random number generator is HTTPS enabled. This means that the website supports secure communication using SSL certificates and encryption. If the website is not HTTPS enabled, it may not be compatible with the SSL redirection implemented by the IT department. SSL redirection is a technique that automatically redirects HTTP requests to HTTPS, ensuring that the data exchanged between the web browser and the website is protected. However, some websites may not have SSL certificates or may have expired or invalid ones, which can cause errors or warnings when trying to access them via HTTPS. Therefore, the technician should check the website's URL and see if it starts with https:// or http://. If it is the latter, the technician should try to manually change it to https:// and see if the website loads correctly. If it does not, the technician should contact the website owner or administrator and ask them to enable HTTPS or update their SSL certificates.
