   A network technician is troubleshooting internet connectivity issues with users in a subnet. From a host, the technician runs tcpdump and then attempts to navigate to a website using a web browser. The technician receives the following output:

   

   Afterward, the browser displays an error. Which of the following explains this issue?

   • AA routing loop is within the network.
   • BThe host is configured with incorrect DNS settings.
   • CA broadcast storm is occurring on the subnet.
   • DThe host is missing a route to the website.

   Show answer

   Answer: B

   Explanation

   chatGPT ; The output provided indicates DNS (Domain Name System) queries from the host (192.168.1.15) attempting to resolve the domain name "comptia.com" by sending DNS queries to the DNS server (192.168.1.252) over UDP (User Datagram Protocol) port 53. However, the queries seem to be failing or encountering issues, as indicated by the repeated attempts with the same destination and port, but varying flags and potentially malformed DNS queries (e.g., "comptia. com" and "comptia-com"). The issue is not with the routing loop, broadcast storm, or missing routes, as the packets are being sent to the DNS server but are not getting successful responses. Given the repeated queries and potential formatting errors in the DNS queries, the most likely explanation for the issue with the browser displaying an error after running tcpdump is: B. The host is configured with incorrect DNS settings.

   After running a Cat 8 cable using passthrough plugs, an electrician notices that connected cables are experiencing a lot of cross talk. Which of the following troubleshooting steps should the electrician take first?

   • AInspect the connectors for any wires that are touching or exposed.
   • BRestore default settings on the connected devices.
   • CTerminate the connections again.
   • DCheck for radio frequency interference in the area.

   Show answer

   Answer: A

   Explanation

   A. Inspect the connectors for any wires that are touching or exposed. The electrician should first inspect the connectors for any wires that are touching or exposed. Cross talk issues can occur if there is improper termination, exposed wires, or if wires are not properly separated within the connectors. Checking the connectors for correct wiring and ensuring there is no physical contact between wires is a crucial step in troubleshooting cross talk in a network cable.

   A user took a laptop on a trip and made changes to the network parameters while at the airport. The user can access all internet websites but not corporate intranet websites. Which of the following is the most likely cause of the issue?

   • ADuplicate IP address
   • BDuplicate SSID
   • CIncorrect DNS
   • DIncorrect subnet mask

   Show answer

   Answer: C

   Explanation

   C. Incorrect DNS The most likely cause of the issue is an Incorrect DNS (Domain Name System) configuration. When the user changed the network parameters, they might have set the DNS server to an incorrect address. As a result, the laptop can access public internet websites (resolved through public DNS servers) but fails to resolve and access corporate intranet websites, as they typically require internal DNS servers.

   Select 2

   Which of the following best describe the functions of Layer 2 of the OSI model? (Choose two.)

   • ALocal addressing
   • BError preventing
   • CLogical addressing
   • DError detecting
   • EPort addressing
   • FError correcting

   Show answer

   Answer: AD

   Explanation

   Yet another question with unclear or non-standard choices. Right away, we can rule out C and E. Layer 3 deals with logical addressing. Layer 4 deals with "port addressing" (very poor wording). Option B seems very unlikely, but maybe CSMA/CA would classify as an error preventing method (collision avoidance). That feels like a stretch, though. Not to mention most Net+ materials won't mention "error preventing" methods. Finally, in the context of Ethernet networks, Layer 2 does not do any error correcting, so F is probably out. So with B, C, E, and F ruled out, we have A and D. Everyone should know that Layer 2 deals with error detection, so D is a given. The last bit of garbage wording is "local addressing." The standard terms are physical address, hardware address, or MAC address. Assuming that local addressing refers to MAC addresses, the overall answer is A and D. Come on CompTIA! A certification exam like this should only use clear, unambiguous, standard terminology. Stop forcing us to make assumptions and guess what you really mean. Okay, I'm done ranting.

   An engineer is configuring redundant network links between switches. Which of the following should the engineer enable to prevent network stability issues?

   • A802.1Q
   • BSTP
   • CFlow control
   • DCSMA/CD

   Show answer

   Answer: B

   Explanation

   Just adding this here for people like me who forgot what 802.1Q was: IEEE 802.1Q, often referred to as Dot1q, is the networking standard that supports virtual local area networking (VLANs) on an IEEE 802.3 Ethernet network. The standard defines a system of VLAN tagging for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames. The standard also contains provisions for a quality-of-service prioritization scheme commonly known as IEEE 802.1p and defines the Generic Attribute Registration Protocol.

   Following the implementation of a BYOD policy, some users in a high-density environment report slowness over the wireless connection. Some wireless controller reports indicate high latency and airttime contention. Which of the following is the most probable root cause?

   • AThe AP is configured with 2.4GHz frequency, which the new personal devices do not support.
   • BThe AP is configured with 2.4GHz frequency without band-steering capabilities.
   • CThe AP is configured with 5Ghz frequency with band-steering capabilities.
   • DThe AP is configured with 5Ghz frequency, which the new personal devices do not support

   Show answer

   Answer: B

   Explanation

   B. The AP is configured with 2.4GHz frequency without band-steering capabilities. In a high-density environment with a BYOD (Bring Your Own Device) policy, multiple devices are likely contending for the available wireless resources. The 2.4GHz frequency band is more susceptible to interference and contention due to its limited number of non-overlapping channels and its popularity among various devices. Additionally, older devices that do not support 5GHz may also contribute to contention on the 2.4GHz band. Band steering is a feature that helps guide dual-band capable devices to use the less congested 5GHz band. If the access point (AP) is configured with 2.4GHz without band-steering capabilities, it may result in increased contention and latency, especially in high-density scenarios where multiple devices are competing for bandwidth.

    A company’s VoIP phone connection is cutting in and out. Which of the following should be configured to resolve this issue?

    • A802.1Q tagging
    • BJumbo frames
    • CNative VLAN
    • DLink aggregation

    Show answer

    Answer: A

    Explanation

    based on the information provided, option A (802.1Q tagging) is not typically the primary configuration to address VoIP call quality issues. While VLAN configuration, including tagging, is important for network segmentation and organization, directly resolving VoIP call quality issues often involves considerations like Quality of Service (QoS) settings, network congestion management, and ensuring proper prioritization of voice traffic.
