CompTIA Network+ Certification Exam Sample Questions (Q60-Q65):

NEW QUESTION # 60
Users cannot connect to an internal website with an IP address 10.249.3.76. A network administrator runs a command and receives the following output:
1 3ms 2ms 3ms 192.168.25.234
2 2ms 3ms 1ms 192.168.3.100

Which of the following command-line tools is the network administrator using?

A. tracert
B. netstat
C. nmap
D. tcpdump

Answer: A

Explanation:
Understanding Tracert:
tracert (Traceroute in Windows) is a command-line tool used to trace the path that packets take from the source to the destination. It records the route (the specific gateways at each hop) and measures transit delays of packets across an IP network.
Output Analysis:
The output shows a series of IP addresses with corresponding round-trip times (RTTs) in milliseconds.
The asterisks (*) indicate that no response was received from those hops, which is typical for routers or firewalls that block ICMP packets used by tracert.

NEW QUESTION # 61
SIMULATION
Users are unable to access files on their department share located on flle_server 2. The network administrator has been tasked with validating routing between networks hosting workstation A and file server 2.

NEW QUESTION # 62
As part of an attack, a threat actor purposefully overflows the content-addressable memory (CAM) table on a switch. Which of the following types of attacks is this scenario an example of?

A. MAC flooding
B. Evil twin
C. ARP spoofing
D. DNS poisoning

Answer: A

Explanation:
* Definition of MAC Flooding:
* MAC flooding is an attack where a malicious actor sends numerous fake MAC addresses to a switch, overwhelming its CAM table. The CAM table stores MAC addresses and their associated ports for efficient traffic forwarding.
* Impact of MAC Flooding:
* CAM Table Overflow: When the CAM table is full, the switch cannot learn new MAC addresses and is forced to broadcast traffic to all ports, leading to a degraded network performance and
* potential data interception.
* Switch Behavior: The switch operates in a fail-open mode, treating the network as a hub, which can be exploited for eavesdropping on traffic.
* Comparison with Other Attacks:
* ARP Spoofing: Involves sending false ARP (Address Resolution Protocol) messages to associate the attacker's MAC address with the IP address of another device.
* Evil Twin: Involves creating a rogue wireless access point that mimics a legitimate one to intercept data.
* DNS Poisoning: Involves corrupting the DNS cache with false information to redirect traffic to malicious sites.
* Preventive Measures:
* Port Security: Configure port security on switches to limit the number of MAC addresses per port, preventing CAM table overflow.
* Network Segmentation: Use VLANs to segment network traffic and limit the impact of such attacks.

* CompTIA Network+ study materials on network security threats and mitigation techniques.

NEW QUESTION # 63
A network administrator wants users to be able to authenticate to the corporate network using a port-based authentication framework when accessing both wired and wireless devices. Which of the following is the best security feature to accomplish this task?

A. MAC filtering
B. Port security
C. Access control list
D. 802.1X

Answer: D

Explanation:
802.1X is a port-based network access control (PNAC) protocol that provides an authentication mechanism to devices wishing to connect to a LAN or WLAN. It is widely used for secure network access, ensuring that only authenticated devices can access the network, whether they are connecting via wired or wireless means. 802.1X works in conjunction with an authentication server, such as RADIUS, to validate the credentials of devices trying to connect.

NEW QUESTION # 64
A network administrator notices interference with industrial equipment in the 2.4GHz range. Which of the following technologies would most likely mitigate this issue? (Select two).

A. Mesh network
B. Captive portal
C. Non-overlapping channel
D. Ad hoc network
E. 5GHz frequency
F. Omnidirectional antenna

Answer: E

Explanation:
* Understanding 2.4GHz Interference:
* The 2.4GHz frequency range is commonly used by many devices, including Wi-Fi, Bluetooth, and various industrial equipment. This can lead to interference and degraded performance.
* Mitigation Strategies:
* 5GHz Frequency:
* The 5GHz frequency band offers more channels and less interference compared to the 2.4 GHz band. Devices operating on 5GHz are less likely to encounter interference from other devices, including industrial equipment.
* Non-overlapping Channels:
* In the 2.4GHz band, using non-overlapping channels (such as channels 1, 6, and 11) can help reduce interference. Non-overlapping channels do not interfere with each other, providing clearer communication paths for Wi-Fi signals.
* Why Other Options are Less Effective:
* Mesh Network: While useful for extending network coverage, a mesh network does not inherently address interference issues.
* Omnidirectional Antenna: This type of antenna broadcasts signals in all directions but does not mitigate interference.
* Captive Portal: A web page that users must view and interact with before accessing a network, unrelated to frequency interference.
* Ad Hoc Network: A decentralized wireless network that does not address interference issues directly.
* Implementation:
* Switch Wi-Fi devices to the 5GHz band if supported by the network infrastructure and client devices.
* Configure Wi-Fi access points to use non-overlapping channels within the 2.4GHz band to minimize interference.

* CompTIA Network+ study materials on wireless networking and interference mitigation.
