   An AP uses a 98ft (30m) Cat 6 cable to connect to an access switch. The cable is wired through a duct close to a three-phase motor installation. Anytime the three-phase is turned on, all users connected to the switch experience high latency on the network. Which of the following is MOST likely the cause of the issue?

   • AInterference
   • BAttenuation
   • COpen circuit
   • DShort circuit

   Show answer

   Answer: A

   Explanation

   A. Interference The most likely cause of the issue is interference from the three-phase motor installation. Electrical motors, such as the three-phase motor mentioned, can generate electromagnetic interference (EMI) that affects nearby network cables. This interference can lead to high latency, packet loss, or other network issues. To mitigate this problem, consider rerouting the network cable away from the motor or using shielded twisted pair (STP) cables, which are designed to reduce the impact of electromagnetic interference.

5. Question 435 · 871 in bank

   An IT technician installs five old switches in a network. In addition to the low port rates on these switches, they also have improper network configurations. After three hours, the network becomes overwhelmed by continuous traffic and eventually shuts down. Which of the following is causing the issue?

   • ABroadcast storm
   • BCollisions
   • CIP settings
   • DRouting loops

   Show answer

   Answer: A

   Explanation

   A broadcast storm occurs when there is a high volume of broadcast traffic in a network, resulting in network congestion and performance degradation. In this case, the combination of old switches with low port rates and improper network configurations likely leads to the excessive generation and propagation of broadcast traffic. Over time, the continuous flow of broadcast messages overwhelms the network's capacity, causing it to become overwhelmed and eventually shutting it down.

6. Question 436 · 871 in bank

   An engineer is designing a network topology for a company that maintains a large on-premises private cloud. A design requirement mandates internet-facing hosts to be partitioned off from the internal LAN and internal server IP ranges. Which of the following defense strategies helps meet this requirement?

   • AImplementing a screened subnet
   • BDeploying a honeypot
   • CUtilizing network access control
   • DEnforcing a Zero Trust model

   Show answer

   Answer: A

   Explanation

   A. Implementing a screened subnet Implementing a screened subnet, also known as a "DMZ" (Demilitarized Zone), involves creating a separate network segment that acts as an intermediary zone between the internal network and the external (Internet-facing) network. Internet-facing hosts are placed in the DMZ, providing controlled access to services like web servers or email servers, while keeping them separate from the internal LAN and critical server IP ranges. This helps mitigate the risk of external attacks directly affecting internal systems. The other options do not directly address the requirement of partitioning off internet-facing hosts

   A network technician is working at a new office location and needs to connect one laptop to another to transfer files. The laptops are newer models and do not have Ethernet ports. Access points are not available either. Which of the following types of wireless network SSIDs does the network technician need to configure to be able to connect the laptops together?

   • AIndependent Basic Service Set
   • BExtended Service Set
   • CDistribution System Service
   • DBasic Service Set

   Show answer

   Answer: A

   Explanation

   According to ChatGPT v4: The correct option is A. The reason it is not D is below. Option D, Basic Service Set (BSS), is not the correct choice in this scenario because a BSS refers to a single access point that serves a group of devices (stations) within its coverage area. In this situation, there are no access points available to facilitate the connection between the laptops. Instead, the Independent Basic Service Set (IBSS) is the appropriate choice, as it allows the laptops to connect directly to each other without

    A network administrator walks into a datacenter and notices an unknown person is following closely. The administrator stops and directs the person to the security desk. Which of the following attacks did the network administrator prevent?

    • AEvil twin
    • BTailgating
    • CPiggybacking
    • DShoulder surfing

    Answer: B

    Explanation

    A: evil twin It is a access point that looks leginmate, that is used to eavesdrop the wireless communications on the network. B: tailgating The act of following someone without their consent or knowledge C: piggybacking Following the individual with the consent, however piggybacking can also include using another person's wireless connections, and essentially causing issues over the network communications (bandwidth, speed, etc) D: shoulder surfing Finding out information by looking over the shoulders of the individual sitting at a computer or doing something. Sometimes seeing the password they type in as they login to their computer, or obtaining other valuable information just by kind of glancing at the screen. But the case of this question it would be B. Tailgating
