질문 # 38
Which of the following devices forwards data between different networks by analyzing the headers of packets?
정답：C
설명：
A router is a network device that forwards data between different networks by examining packet headers, specifically the IP address information contained in Layer 3 (Network Layer) of the OSI model. According to the CompTIA A+ Core 1 (220-1201) networking objectives, routers use routing tables and packet header analysis to determine the best path for data to travel from a source network to a destination network. When a packet arrives at a router interface, the router reads the destination IP address in the packet header, compares it against its routing table, and then forwards the packet to the appropriate next hop or network interface. This function allows routers to connect multiple networks such as LANs, WANs, and the internet.
The other options do not perform this function. A hub operates at Layer 1 (Physical Layer) and simply broadcasts incoming signals to all connected ports without inspecting any packet information. A repeater also operates at the physical layer and is used only to regenerate or amplify signals to extend network distance. An unmanaged switch operates mainly at Layer 2 (Data Link Layer) and forwards frames based on MAC addresses, not IP packet headers. Because only routers analyze packet headers and forward traffic between different networks, Router is the correct answer.
질문 # 39
Which of the following best blocks unwanted traffic on a network?
정답：D
설명：
A firewall examines network traffic and permits or blocks it according to configured security rules. Rules can be based on characteristics such as:
* Source or destination IP address.
* Network protocol.
* Source or destination port.
* Connection state.
* Application or service.
* Direction of communication.
This makes a firewall the device that most directly blocks unauthorized or unwanted network traffic.
* An access point provides wireless network connectivity.
* A switch forwards Ethernet frames between devices on a local network.
* A router directs packets between different IP networks. Some routers contain integrated firewall functionality, but routing itself is not the primary security control described by the question.
CompTIA objective 2.5 includes firewalls among common network hardware devices. Microsoft describes a firewall as a technology that filters network traffic and blocks unauthorized access.
질문 # 40
An administrator has to enable automatic private IP reservations and assignments to a number of computers. Which of the following should the administrator use?
정답：B
설명：
DHCP automatically assigns IP configuration to client computers and supports reservations that consistently provide a specific IP address to a device based on its network adapter's MAC address.
질문 # 41
Which of the following cable types requires a user to manually turn the connector in a clockwise direction in order to securely attach the cable?
정답：B
설명：
Coaxial cables use threaded connectors, such as F-type connectors, that must be twisted clockwise to securely attach them to a port, ensuring a firm connection and proper signal transmission.
질문 # 42 
Which of the following is the most likely cause?
정답：B
설명：
The key detail in the ipconfig output is that the system is receiving an IP address, subnet mask, default gateway, and DHCP server information via DHCP, but the DNS servers shown are 8.8.8.8 and 8.8.4.4, which are Google's public DNS servers. In most corporate networks, DNS is provided internally by the DHCP server-usually the same device assigning the IP address. When DNS values are different from DHCP- provided defaults, it indicates manual DNS configuration.
CompTIA A+ emphasizes that mismatched DNS settings can cause browsing issues, name-resolution delays, or an inability to access internal resources. DNS is critical because it translates domain names into IP addresses; if manually configured, the device bypasses the organization's DNS server and may not resolve internal hostnames.
The subnet mask is correct for a Class B private network subdivided using /24 (255.255.255.0). NetBIOS being enabled is common and not a cause of connectivity issues here. DHCP being enabled is normal and functioning correctly, as shown by the proper IP lease obtained.
Thus, the anomalous and most likely problematic configuration is manually configured DNS, making Option D correct.
