Which of the following often-overlooked parts of the asset life cycle can cause the greatest number of issues in relation to Pll exposure?
Correct Answer:
D
Disposal is the part of the asset life cycle that can cause the greatest number of issues in relation to PII exposure. PII stands for personally identifiable information, which is any data that can be used to identify a specific individual, such as name, address, phone number, email, social security number, etc. PII exposure is the unauthorized access or disclosure of PII, which can result in identity theft, fraud, or other harms to the individuals whose data is compromised. Disposal is the process of getting rid of an asset that is no longer needed or useful, such as a server, a hard drive, or a mobile device. If the disposal is not done properly, the PII stored on the asset may still be accessible or recoverable by unauthorized parties, such as hackers, thieves, or competitors. Therefore, it is important to follow best practices for secure disposal of assets that contain PII, such as wiping, encrypting, shredding, or physically destroying the data storage media
A technician recently applied a critical OS patch to a working sever. After rebooting, the technician notices the server Is unable to connect to a nearby database server. The technician validates a connection can be made to thedatabasefrom another host. Which of the following is the best NEXT step to restore connectivity?
Correct Answer:
C
A host firewall is a software that controls the incoming and outgoing network traffic on a server based on predefined rules and filters. It can block or allow certain ports, protocols, or addresses that are used for communication with other servers or devices. If a server is unable to connect to another server after applying a patch, it is possible that the patch changed or added a firewall rule that prevents the connection. The administrator should check the host firewall rule and modify it if necessary to restore connectivity. Verified References: [Host firewall], [Network connection]
A technician set up a new multifunction printer. After adding the printer to the print server, the technician configured the printer on each user's machine. Several days later, users reported that they were no longer able to print, but scanning to email worked. Which of the following is most likely causing this issue?
Correct Answer:
D
The most likely cause of this issue is that the printer had DHCP enabled, which changed its IP address after adding it to the print server and configuring it on each user’s machine. DHCP (Dynamic Host Configuration Protocol) is a network protocol that assigns IP addresses and other network configuration parameters to devices automatically, without manual intervention. DHCP can simplify network management and avoid IP conflicts, but it can also cause problems if the devices are not configured to use static or reserved IP addresses. If the printer had DHCP enabled, it might have received a different IP address from the DHCP server after rebooting or reconnecting to the network, which would make it unreachable by the print server and the users’ machines that were configured with the previous IP address. Scanning to email would still work, as it does not depend on the print server or the users’ machines, but on the printer’s SMTP settings and internet connection.

A company wants to deploy software to all users, Out very few of men will be using the software at any one point in time. Which of the following licensing models would be BEST lot the company?
Correct Answer:
B
Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines.References: https://www.pcmag.com/encyclopedia/term/concurrent-use-licensehttps://www.techopedia.com/definition/1440/software-licensing
An administrator is troubleshooting an application performance issue on a virtual server with two vCPUs. The application performance logs indicate CPU contention. The administrator adds more vCPU cores to the VM, yet the issue persists. Which of the following is the most likely reason for this issue?
Correct Answer:
C
A single-threaded application is an application that can only execute one task or process at a time. A single-threaded application can only utilize one CPU core, regardless of how
many cores are available or assigned to the virtual machine. Therefore, adding more vCPU cores to the VM will not improve the performance of the application, as it will still be limited by the speed and capacity of one core12.
To troubleshoot this issue, the administrator should check if the application is single- threaded or multi-threaded. This can be done by using tools such as Task Manager, Performance Monitor, or Process Explorer on Windows, or top, htop, or ps on Linux34. If the application is single-threaded, the administrator should consider the following options:
✑ Reduce the number of vCPU cores on the VM to match the number of threads that
the application can use. This can help avoid CPU contention and co-stop issues that may arise from having too many vCPUs relative to the number of physical cores on the host5.
✑ Upgrade the physical CPU on the host to a faster or newer model that can provide
higher clock speed and performance for the single core that the application uses.
✑ Optimize the application code or configuration to make it more efficient or multi- threaded, if possible. This can help the application take advantage of multiple cores and improve its performance.
