NEW QUESTION # 239
A user recently made changes to a PC that caused it to be unable to access websites by both FQDN and IP Local resources, such as the file server remain accessible. Which of the following settings did the user MOST likely misconfigure?

• A. DNS entries
• B. Local host file
• C. Default gateway
• D. Static IP

Answer: C

Explanation:
The default gateway is the setting that the user most likely misconfigured on the PC that caused it to be unable to access websites by both FQDN and IP. The default gateway is a device, usually a router or a firewall, that connects a local network to other networks such as the Internet. It acts as an intermediary between devices on different networks and forwards packets based on their destination IP addresses. If the default gateway is not configured correctly on a PC, it will not be able to communicate with devices outside its local network, such as web servers or DNS servers.

NEW QUESTION # 241
Which of the following is a characteristic of the application layer?

• A. It encrypts data in transit.
• B. It performs address translation.
• C. It checks independently for packet loss.
• D. It relies upon other layers for packet delivery.

Answer: D

Explanation:
The application layer is the highest layer of the OSI model, and it provides the interface between the user and the network. It does not handle the details of packet delivery, such as addressing, routing, error checking, or encryption. Those functions are performed by the lower layers of the OSI model. The application layer only focuses on the format, content, and presentation of the data.

NEW QUESTION # 242
A company is moving to a new building designed with a guest waiting area that has existing network ports. Which of the following practices would BEST secure the network?

• A. Enable MAC filtering to block unknown hardware addresses.
• B. Ensure all guests sign an NDA.
• C. Disable unneeded switchports in the area.
• D. Lower the radio strength to reduce Wi-Fi coverage in the waiting area.

Answer: C

Explanation:
One of the best practices to secure the network would be to disable unneeded switchports in the guest waiting area. This will prevent unauthorized users from connecting to the network through these ports. It's important to identify which switchports are not in use and disable them, as this will prevent unauthorized access to the network.
Other practices such as ensuring all guests sign an NDA, lowering the radio strength to reduce Wi-Fi coverage in the waiting area and enabling MAC filtering to block unknown hardware addresses are not as effective in securing the network as disabling unneeded switchports. Enforcing an NDA with guests may not stop a malicious user from attempting to access the network, reducing the radio strength only limits the Wi-Fi coverage, and MAC filtering can be easily bypassed by hackers.

NEW QUESTION # 243
Which of the following passwords would provide the best defense against a brute-force attack?

• A. Password! 1
• B. ThislsMyPasswordForWork
• C. T5!8j5
• D. Qwerty!@#$

Answer: C

Explanation:
A brute-force attack is a method of guessing passwords by trying every possible combination of characters until the correct one is found. The longer and more complex the password, the harder it is to crack by brute-force. A password that provides the best defense against a brute-force attack should have a combination of uppercase and lowercase letters, numbers, and special characters, and should be as long as possible. The password T5!8j5 meets these criteria, while the other options are either too short, too simple, or too common.

NEW QUESTION # 251
An organization recently connected a new computer to the LAN. The user is unable to ping the default gateway. Which of the following is the most likely cause?

• A. The VLAN is incorrect.
• B. The DHCP server is not available.
• C. A static IP is assigned.
• D. An RFC1918 address is being used

Answer: B

Explanation:
Explanation
The DHCP server is not available is the most likely cause of the issue where a new computer is unable to ping the default gateway. DHCP stands for Dynamic Host Configuration Protocol, which is a network protocol that automatically assigns IP addresses and other configuration parameters to clients on a network. The default gateway is the IP address of the router or device that connects a local network to other networks, such as the internet. Pinging is a network utility that tests the connectivity and reachability between two devices by sending and receiving echo packets. If the DHCP server is not available, the new computer will not be able to obtain an IP address or other configuration parameters, such as the default gateway, from the DHCP server.
This will prevent the new computer from communicating with other devices on the network or the internet, resulting in ping failure. References: [CompTIA Network+ Certification Exam Objectives], What Is DHCP? | How DHCP Works | SolarWinds MSP

NEW QUESTION # 254
After installing a series of Cat 8 keystones, a data center architect notices higher than normal interference during tests. Which of the following steps should the architect take to troubleshoot the issue?

• A. Connect the RX/TX wires to different pins.
• B. Check to see if the end connections were wrapped in copper tape before terminating.
• C. Run a speed test on a device that can only achieve 100Mbps speeds.
• D. Use passthrough modular crimping plugs instead of traditional crimping plugs.

Answer: B

Explanation:
Cat 8 keystones are shielded to prevent interference from external sources, but they also require proper grounding to avoid interference from within the cable. Wrapping the end connections with copper tape before terminating them is one way to ensure a good ground connection and reduce interference. Using passthrough modular crimping plugs, connecting the RX/TX wires to different pins, or running a speed test on a slow device are not relevant or effective steps to troubleshoot the issue.

NEW QUESTION # 255
A company has multiple offices around the world. The computer rooms in some office locations are too warm Dedicated sensors are in each room, but the process of checking each sensor takes a long time. Which of the following options can the company put In place to automate temperature readings with internal resources?

• A. Hire a programmer to write a script to perform the checks
• B. Use SNMP with an existing collector server
• C. Utilize ping to measure the response.
• D. Implement NetFlow.

Answer: B

Explanation:
SNMP (Simple Network Management Protocol) is a protocol that allows network devices to communicate with a management server. By using SNMP, the company can set up an SNMP agent on each sensor, which will report its temperature readings to an existing collector server. This will enable the company to monitor the temperatures of all their sensors in real-time without the need for manual checks. Additionally, SNMP's scalability means that even if the company adds more rooms or sensors, the existing system can be easily expanded to accommodate them.

NEW QUESTION # 256
An infrastructure company is implementing a cabling solution to connect sites on multiple continents. Which of the following cable types should the company use for this project?

• A. Multimode
• B. Single-mode
• C. Cat 7
• D. Cat 6

Answer: B

Explanation:
Explanation
Single-mode fiber is a type of optical fiber that has a small core diameter and allows only one mode of light to propagate. This reduces signal attenuation and increases transmission distance, making it suitable for long-distance communication networks. Single-mode fiber can carry data over thousands of kilometers without requiring repeaters or amplifiers. Single-mode fiber is also immune to electromagnetic interference and has a higher bandwidth than multimode fiber. Therefore, single-mode fiber is the best cable type for connecting sites on multiple continents. References: [CompTIA Network+ Certification Exam Objectives],
[Single-mode optical fiber - Wikipedia]
Single-mode fiber optic cable uses a single ray of light to transmit data. This allows it to achieve very low attenuation and high bandwidth.
Multimode fiber optic cable uses multiple rays of light to transmit data. This results in higher attenuation and lower bandwidth than single-mode cable.
Twisted pair copper cable uses two insulated copper wires to transmit data. It is less expensive than fiber optic cable, but it has higher attenuation and lower bandwidth.
When choosing a cable type for a long-distance application, it is important to consider the following factors:
Attenuation: The amount of signal loss that occurs over the length of the cable.
Bandwidth: The amount of data that can be transmitted over the cable per second.
Cost: The cost of the cable and installation.
Single-mode fiber optic cable is the best choice for long-distance applications because it has the lowest attenuation and highest bandwidth of any cable type. However, it is also the most expensive cable type.

NEW QUESTION # 260
A user tries to ping 192.168.1.100 from the command prompt on the 192.168.2.101 network but gets the following response: U.U.U.U. Which of the following needs to be configured for these networks to reach each other?

• A. Loopback
• B. Routing protocol
• C. Default gateway
• D. Network address translation

Answer: C

Explanation:
A default gateway is a device that routes traffic from one network to another network, such as the Internet. A default gateway is usually configured on each host device to specify the IP address of the router that connects the host's network to other networks. In this case, the user's device and the destination device are on different networks (192.168.1.0/24 and 192.168.2.0/24), so the user needs to configure a default gateway on their device to reach the destination device.
