Answer : D

The Syslog server collects logs and system messages from devices on a network. It's a standard protocol used to store log messages from network hardware like routers, switches, and servers for diagnostics and auditing.

Option A (DNS): Translates domain names into IP addresses, not used for logging.

Option B (Mail): Manages email communication.

Option C (Print): Manages print jobs and printer sharing.

Answer : C

A DHCP lease is a temporary assignment of an IP address and other network configuration parameters (such as DNS and gateway) to a device. The lease is renewed periodically to maintain the assignment.

Why Not A (A definition of the scope of addresses): The DHCP scope defines the range of IP addresses but is not the lease itself.

Why Not B (A reservation of an IP configuration): DHCP reservations ensure a specific device always receives the same IP address, but this is not the lease.

Why Not D (A translation of network names to IP addresses): This describes DNS, not DHCP.

Answer : C

Upgrading to an SSD (Solid State Drive) is the best way to meet the user's requirements because it will improve the performance and storage capacity of the laptop. SSDs are faster than HDDs (Hard Disk Drives) because they have no moving parts and can access data more quickly. SSDs also have lower power consumption, lower heat generation, and higher reliability than HDDs. Therefore, upgrading to an SSD will make the laptop more responsive, boot faster, and handle large files better.

According to some web sources, SSDs are the best hard drives for video editing because they can streamline the workflow and store masses of footage in one easy-to-access place1. SSDs are also one of the most common PC upgrades that can make a dramatic difference, especially for aging systems2. Additionally, Adobe recommends using SSDs for Premiere Pro and After Effects because they can handle large media files and cache data more efficiently3.

Answer : A

A custom hosts file is a file that maps hostnames to IP addresses, allowing the user to access websites or servers by their names instead of their numerical addresses. For example, a user can add a line like192.168.1.100 myserver.localto their hosts file and then access the server by typingmyserver.localin their browser. However, this method only works if the IP address of the server does not change. If the server is configured with a dynamic IP address, which means it can be assigned a different IP address by the network router or DHCP server, then the hosts file entry will become invalid and the user will not be able to connect to the server by its hostname. Therefore, the technician should ensure that the server is configured with a static IP address, which means it has a fixed and permanent IP address that does not change. This way, the hosts file entry will always point to the correct IP address of the server and the user will be able to ping the server hostname from their computer.

If a laptop's external webcam software is running, but it shows no image or video, the first step the technician should perform is to reseat the webcam. Reseating the webcam involves disconnecting it from the motherboard and then reconnecting it. If this doesn't work, the technician should then check the webcam drivers or software.

Answer : D

The correct answer is D. Default gateway.

A default gateway is the device that connects a local network to other networks, such as the internet. A default gateway is usually a router or a modem that has an IP address on the same subnet as the local network. A default gateway is necessary for a device to communicate with devices outside its local network.

In this case, the user has a self-configured, static IP address of 192.168.1.20, which belongs to the subnet 192.168.1.0/24 (with a subnet mask of 255.255.255.0). However, the default gateway is set to 192.168.0.1, which belongs to a different subnet (192.168.0.0/24). This means that the user's device cannot reach the default gateway, and therefore cannot connect to the internet.

The technician should edit the default gateway to match the correct subnet of the user's device, such as 192.168.1.1 or 192.168.1.254, depending on the configuration of the network.

Answer : A

Near field communication (NFC) is a function that enables contactless payments with a phone by allowing it to communicate with compatible devices within close proximity. If NFC is not working properly, the user will not be able to perform contactless payments with the phone. Hotspot is a feature that allows a device to share its internet connection with other devices via Wi-Fi, Bluetooth, or USB. Bluetooth is a wireless technology that allows devices to connect and exchange data over short distances.USB is a standard interface that connects devices such as keyboards, mice, flash drives, etc
