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?  Interference  Attenuation  Open circuit  Short circuit Interference is a phenomenon that occurs when unwanted signals or noise affect the transmission or reception of data signals on a network. Interference can cause network issues such as high latency, low throughput, packet loss, or errors. Interference can be caused by various sources, such as electromagnetic fields, radio waves, power lines, or electrical devices. In this scenario, the three-phase motor installation is a source of interference that affects the Cat 6 cable that connects the AP to the access switch. The cable is wired through a duct close to the motor installation, which exposes it to the electromagnetic fields generated by the motor. Anytime the motor is turned on, the interference causes high latency for all users connected to the switch.QUESTION 173A network administrator is configuring a load balancer for two systems. Which of the following must the administrator configure to ensure connectivity during a failover?  VIP  NAT  APIPA  IPv6 tunneling  Broadcast IP A virtual IP (VIP) address must be configured to ensure connectivity during a failover. A VIP address is a single IP address that is assigned to a group of servers or network devices. When one device fails, traffic is automatically rerouted to the remaining devices, and the VIP address is reassigned to the backup device, allowing clients to continue to access the service without interruption.Reference:CompTIA Network+ Certification Study Guide, Exam N10-007, Fourth Edition, Chapter 6: Network Servers, p. 300QUESTION 174A software developer changed positions within a company and is now a sales engineer. The security team discovered that the former software developer had been modifying code to implement small features requested by customers. Which of the following would be the best thing for the security administrator to implement to prevent this from happening?  A software patching policy  A role-based access control policy  Firewalls on the software development servers  Longer and more complex password requirements QUESTION 175An organization with one core and five distribution switches is transitioning from a star to a full-mesh topology Which of the following is the number of additional network connections needed?  5  7  10  15 10 additional network connections are needed to transition from a star to a full-mesh topology. A star topology is a network topology where each device is connected to a central device, such as a switch or a hub. A full-mesh topology is a network topology where each device is directly connected to every other device. The number of connections needed for a full-mesh topology can be calculated by the formula n(n-1)/2, where n is the number of devices. In this case, there are six devices (one core and five distribution switches), so the number of connections needed for a full-mesh topology is 6(6-1)/2 = 15. Since there are already five connections in the star topology (one from each distribution switch to the core switch), the number of additional connections needed is 15 – 5 = 10.

Which of the following is MOST likely causing the issue?  DHCP scope exhaustion  Signal attenuation  Channel overlap  Improper DNS configuration DHCP scope exhaustion occurs when the number of available IP addresses to be leased from a DHCP server have been used up. This could be caused by a large number of clients on the network, or a misconfigured DHCP scope. When this happens, clients will be assigned an IP address from the APIPA range (169.254.0.0 to 169.254.255.255). To resolve this issue, the DHCP scope needs to be expanded or adjusted to accommodate the number of clients on the network.QUESTION 181A network technician is troubleshooting an application issue.

The policy for this server is to only allow traffic on port 443. The firewall administrator needs to investigate how this change occurred to prevent a reoccurrence. Which of the following should the firewall administrator do next?  Consult the firewall audit logs.  Change the policy to allow port 80.  Remove the server object from the firewall policy.  Check the network baseline. QUESTION 194A technician is troubleshooting reports that a networked printer is unavailable. The printer’s IP address is configured with a DHCP reservation, but the address cannot be pinged from the print server in the same subnet. Which of the following is MOST likely the cause of me connectivity failure?  Incorrect VLAN  DNS failure  DHCP scope exhaustion  Incorrect gateway * A VLAN is a virtual local area network that logically separates devices on the same physical network.VLANs can improve network performance, security, and management by reducing broadcast domains and isolating traffic.* A DHCP reservation is a feature that allows a network administrator to assign a specific IP address to a device based on its MAC address. This ensures that the device always receives the same IP address from the DHCP server, even if the lease expires or the device reboots.* A networked printer is a device that can be shared by multiple users on the same network. A networked printer typically has a built-in network interface card (NIC) that allows it to communicate with other devices using TCP/IP protocols.* A print server is a device or a software application that manages the printing requests from multiple clients. A print server can also provide additional features such as print queue management, printer driver installation, and printer status monitoring.* A subnet is a logical division of an IP network that allows devices to communicate more efficiently and securely. A subnet is defined by a network address and a subnet mask, which determine the range of valid IP addresses within the subnet. Devices on the same subnet can communicate directly with each other without the need for a router.* A ping is a network diagnostic tool that tests the connectivity and reachability between two devices by sending and receiving echo packets. A ping request can fail for various reasons, such as network congestion, firewall settings, routing issues, or device configuration errors.* Based on the question, the networked printer is unavailable because it cannot be pinged from the print server in the same subnet. This means that there is a problem with the layer 2 connectivity between the two devices, which is determined by the MAC addresses and the VLANs. The most likely cause of this problem is that the printer and the print server are on different VLANs, which prevents them from communicating with each other. The other options are less likely because they affect the layer 3 connectivity, which is determined by the IP addresses and the gateways. A DNS failure would not affect the ping request, since it uses IP addresses and not hostnames. A DHCP scope exhaustion would not affect the printer, since it has a DHCP reservation that guarantees its IP address. An incorrect gateway would not affect the communication within the same subnet, since it is only used for routing packets to other networks.

The technician checks the cable gong from the phone to the switch, and the cable is good. Which of the following actions IS needed for this phone to work?  Add a POE injector  Enable MDIX.  Use a crossover cable.  Reconfigure the port. * A POE injector is a device that provides power and data over a single Ethernet cable to a POE device, such as a VoIP phone, a wireless access point, or a security camera12.* A POE injector is needed when the switch or router that connects to the POE device does not support POE or does not have enough POE ports available12.* A POE injector can be installed between the switch or router and the POE device, using two Ethernet cables: one from the switch or router to the injector, and another from the injector to the POE device12.* A POE injector can supply up to 30W of power per port, depending on the POE standard it supports (802.3af or 802.3at)12.* B. Enable MDIX is not a correct answer because MDIX is a feature that allows a switch or router to automatically detect the type of cable (straight-through or crossover) and adjust the pin assignments accordingly34.* MDIX is not related to providing power to a POE device, and it is usually enabled by default on modern switches and routers34.* C. Use a crossover cable is not a correct answer because a crossover cable is a type of Ethernet cable that swaps the transmit and receive pairs of wires, allowing two devices of the same type (such as two switches or two computers) to communicate directly56.* A crossover cable is not needed to connect a VoIP phone to a switch or router, as they are different types of devices that use different pin assignments56.* A crossover cable also does not provide power to a POE device, and it may not work with gigabit Ethernet or auto-MDIX devices56.* D. Reconfigure the port is not a correct answer because reconfiguring the port on the switch or router that connects to the VoIP phone does not address the issue of providing power to the phone78.* Reconfiguring the port may involve changing the speed, duplex, VLAN, or security settings, but none of these affect the power delivery to the POE device78.* Reconfiguring the port may also cause network connectivity or performance issues if the settings are not compatible with the VoIP phone or the network78.References:* What Is a PoE Injector and How to Use It? | FS Community* Power Injector for PoE Networks | Eaton* CCNA / CCENT / Network+ Tutorial: Crossover Cables And Auto MDI-X* Straight-Through and Crossover Cables – N10-008 CompTIA Network+ : 2.3* Straight-Through, Crossover, and Rollover Cables – CompTIA Network+ N10-006 – 1.5* CompTIA Network+ Cheat Sheet (Updated for Latest Exam) – StationX* CompTIA Network+ : Common TCP And UDP Default Ports – Tutorialsweb.Com* A Guide to Network Troubleshooting – CompTIA Loading … Prepare for the Actual CompTIA Network+ N10-008 Exam Practice Materials Collection: https://www.topexamcollection.com/N10-008-vce-collection.html --------------------------------------------------- Images: https://blog.topexamcollection.com/wp-content/plugins/watu/loading.gif https://blog.topexamcollection.com/wp-content/plugins/watu/loading.gif --------------------------------------------------- --------------------------------------------------- Post date: 2024-11-17 10:08:08 Post date GMT: 2024-11-17 10:08:08 Post modified date: 2024-11-17 10:08:08 Post modified date GMT: 2024-11-17 10:08:08
