質問 # 378
A software developer used client-side virtualization on a server to configure a web application. Although the application is working locally on the software developer's PC, other users on the LAN are not able to access the application. Which of the following would allow other users to access the application?
- A. Virtual desktop
- B. Application virtualization
- C. Site-to-site VPN
- D. Bridge networking
正解：D
解説：
Explanation
Client-side virtualization is used to run an application or process on a separate virtual machine, isolated from the main operating system. To allow other users on the LAN to access the application, the software developer should configure a bridge networking connection between the virtual machine and the LAN. This will allow the virtual machine to communicate with other computers on the network. Application virtualization, virtual desktop, and site-to-site VPN are not necessary steps for allowing other users to access the application.
質問 # 379
Which of the following allows several websites from different companies to be housed on the same virtual server?
- A. Rapid elasticity
- B. Shared resources
- C. Metered utilization
- D. High availability
正解：B
解説：
Shared resources is the concept that allows several websites from different companies to be housed on the same virtual server. A virtual server is a software-based server that runs on a physical server and can host multiple virtual machines (VMs). Each VM can run a different operating system and application, such as a website, and have its own allocated resources, such as CPU, memory, disk space, and network bandwidth.
However, the VMs share the underlying hardware resources of the physical server, which reduces the cost and complexity of maintaining separate servers for each website. This also enables rapid scalability, as new VMs can be created or deleted as needed.
One of the methods to host multiple websites on the same virtual server is to use virtual hosts. Virtual hosts are a feature of web servers, such as Apache, that allow the web server to serve different websites based on the domain name or IP address requested by the client. For example, a web server can host two websites, a.
example.com and b.example.com, on the same virtual server and the same port (such as 80 or 443), by using virtual hosts to map each domain name to a different document root directory. The web server will then deliver the content of the corresponding website to the client based on the domain name in the HTTP request header.

- A. Check the phone's health status
- B. Turn off the phone
- C. Replace the phone's SIM card
- D. Disable VPN on the phone
正解：B
解説：
When a phone's battery overheats and expands, it poses a significant safety risk, including the potential for fire or the battery bursting. The first and most critical action is to turn off the device to prevent further chemical reactions within the battery that could exacerbate the situation. Turning off the phone halts its operations, minimizing the heat generation and reducing the risk of further damage or danger. This is a precautionary measure to ensure the user's safety and to prevent any additional harm to the phone itself. It's important for the user to not attempt to charge or use the phone in this condition and to seek professional help or replacement of the battery or device as needed.

質問 # 386
After a technician replaced a printer's ink cartridges, all the print jobs contain shadowing. Which of the following should the technician do first?
- A. Replace the fuser assembly.
- B. Run the printer's alignment process.
- C. Install the maintenance kit.
- D. Reseat the new ink cartridges.
正解：B
解説：
Running the printer's alignment process is the first step that a technician should do to fix the shadowing problem on the printouts. Shadowing is a print quality issue that occurs when the printer prints a faint duplicate image of the original text or graphics, usually slightly offset from the original position. This can be caused by a misalignment of the printhead, which is the part of the printer that sprays ink onto the paper. The printer's alignment process is a procedure that adjusts the position and angle of the printhead to ensure that the ink is applied accurately and evenly on the paper. The printer's alignment process can be performed from the printer's menu, the printer's software, or the printer's maintenance tool, depending on the model and type of the printer.
The other options are not the best solutions for this problem. Reseating the new ink cartridges may not solve the shadowing issue, unless the cartridges are not properly installed or recognized by the printer. However, this is unlikely to be the case, as the printer would usually display an error message or refuse to print if the cartridges are not compatible or inserted correctly. Replacing the fuser assembly or installing the maintenance kit are more drastic and expensive measures that are usually done when the printer has more serious problems, such as paper jams, smearing, streaking, or fading. The fuser assembly is the part of the printer that heats and melts the toner onto the paper, and the maintenance kit is a set of components that need to be replaced periodically to keep the printer in good condition. These parts are not directly related to the shadowing issue, and replacing them may not fix the problem.

質問 # 387
A user reports poor performance on the application server.
INSTRUCTIONS
Click on Server 1 and Server 2 and review the information presented in each chart to determine which drives need to be replaced.
Select the appropriate replacement drive that should be used, for the least performance degradation to the server.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
正解：
解説：
See the detailed solution in explanation below.
Explanation:
The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.
Recommended Replacement Drive:
To minimize performance degradation, the replacement drive should be:
SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).
Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.
In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.
A user reports poor performance on the
application server.

質問 # 389
A company gives users microSD cards to install on smartphones so users can store pictures that will be used on the website. After installing the cards, users report only being able to save a small number of pictures on the microSD cards before running out of space. Which of the following is the most likely issue?
- A. The microSD cards are not compatible with the smartphones.
- B. The microSD cards are not capable of UHD storage.
- C. The microSD cards were not properly formatted before being installed.
- D. The microSD cards were not selected for camera storage.
正解：C
解説：
If users are only able to save a small number of pictures on the microSD cards before running out of space, it suggests a formatting issue. Improper or incomplete formatting can lead to the card not utilizing its full storage capacity, resulting in significantly less available space for storing pictures. Formatting the microSD cards correctly would ensure the file system on the cards is set up properly, allowing the devices to use the full capacity of the cards for storage. Compatibility, UHD storage capability, and camera storage settings are less likely to be the issue in this scenario.

質問 # 391
A technician is configuring a desktop RAID to allow for the best I/O performance and the most storage capacity possible. Which of the following RAID types should the technician use?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
RAID 0 is a disk array configuration that splits data across two or more disks without parity or mirroring.
RAID 0 provides the best I/O performance because it allows parallel read and write operations on multiple disks. RAID 0 also provides the most storage capacity possible because it does not use any disk space for redundancy. However, RAID 0 does not provide any fault tolerance and increases the risk of data loss if any disk fails.

A user with an older laptop is unable to connect to the office network after new access points were installed.
The user confirms that from home the laptop can connect wirelessly to the network. Which of the following should the user to do to quickly resolve the issue?
- A. Connect a new biometric device.
- B. Install a new SSD
- C. Connect a new USB adapter.
- D. Install a new Bluetooth card.
正解：C
解説：
A USB adapter is a device that can plug into a USB port on a laptop and provide wireless connectivity to a network. A USB adapter can support different wireless standards, such as 802.11a, 802.11b, 802.11g, 802.11n, or 802.11ac. A USB adapter can also support different wireless frequencies, such as 2.4 GHz or 5 GHz.
In this case, the user with an older laptop may not be able to connect to the office network after new access points were installed because the laptop's built-in wireless card does not support the same wireless standard or frequency as the new access points. For example, if the new access points use 802.11ac and 5 GHz, and the laptop's wireless card only supports 802.11g and 2.4 GHz, the laptop will not be able to communicate with the access points.
To quickly resolve this issue, the user should connect a new USB adapter that supports the same wireless standard and frequency as the new access points. This way, the user can bypass the laptop's wireless card and use the USB adapter to connect to the office network wirelessly.

質問 # 398
Which of the following services checks whether the sender's IP address is associated with the sender's domain name when receiving email?
- A. DKIM
- B. MX
- C. SPF
- D. DMARC
正解：C
解説：
SPF stands for Sender Policy Framework, which is a protocol that allows domain owners to specify which IP addresses are authorized to send email on behalf of their domains. SPF helps prevent email spoofing and phishing by verifying the sender's identity and preventing unauthorized use of their domain name.
When an email is received, the receiving server checks the SPF record of the sender's domain, which is a DNS TXT record that lists the valid IP addresses for that domain. The server then compares the sender's IP address with the SPF record and determines if it matches or not. If it matches, the email passes the SPF check and is accepted; if it does not match, the email fails the SPF check and is rejected or marked as spam.
