CompTIA N10-008 certification is an industry-recognized credential that can help you start or advance your IT career. It is the only vendor-neutral, performance-based certification covering more than a single technology. CompTIA N10-008 validates an IT professional's ability to: Implement appropriate wireless technology.Implement basic network security.Identify the purpose and basic operation of network components.Install, configure and perform maintenance of network infrastructure.   NEW QUESTION 142A network technician is hired to review all the devices within a network and make recommendations to improve network efficiency. Which of the following should the technician do FIRST before reviewing and making any recommendations?  Capture a network baseline  Perform an environmental review.  Read the network logs  Run a bandwidth test ExplanationBefore making any recommendations, a network technician should first capture a network baseline, which is a snapshot of the current performance of the network. This will give the technician a baseline to compare against after any changes are made. According to the CompTIA Network+ Study Manual, the technician should“capture the state of the network before making any changes and then compare the performance after the changes have been made. This will provide an accurate baseline to compare the performance of the network before and after the changes have been made.”NEW QUESTION 143Which of the following routing protocols is used to exchange route information between public autonomous systems?  OSPF  BGP  EGRIP  RIP NEW QUESTION 144A customer wants to segregate the traffic between guests on a hypervisor. Which of the following does a technician need to configure to meet the requirement?  Virtual switches  OSPF routing  Load balancers  NIC teaming  Fibre Channel NEW QUESTION 145A technician wants to deploy a new wireless network that comprises 30 WAPs installed throughout a three-story office building. All the APs will broadcast the same SSID for client access. Which of the following BEST describes this deployment?  Extended service set  Basic service set  Unified service set  Independent basic service set NEW QUESTION 146Several end users viewing a training video report seeing pixelated images while watching. A network administrator reviews the core switch and is unable to find an immediate cause. Which of the following BEST explains what is occurring?  Jitter  Bandwidth  Latency  Giants Explanation“Jitter is the loss of packets due to an overworked WAP. Jitter shows up as choppy conversations over a video call, strange jumps in the middle of an online game-pretty much anything that feels like the network has missed some data. Latency is when data stops moving for a moment due to a WAP being unable to do the work. This manifests as a Word document that stops loading, for example, or an online file that stops downloading.”NEW QUESTION 147A technician is searching for a device that is connected to the network and has the device’s physical network address. Which of the following should the technician review on the switch to locate the device’s network port?  IP route table  VLAN tag  MAC table  QoS tag NEW QUESTION 148The management team needs to ensure unnecessary modifications to the corporate network are not permitted and version control is maintained. Which of the following documents would BEST support this?  An incident response plan  A business continuity plan  A change management policy  An acceptable use policy NEW QUESTION 149A technician is documenting an application that is installed on a server and needs to verify all existing web and database connections to the server. Which of the following tools should the technician use to accomplish this task?  tracert  ipconfig  netstat  nslookup NEW QUESTION 150A network technician is troubleshooting a new web server connectivity issue. The network technician discovers the following on the support ticket* The server’s IP address can be pinged from the client PCs,* Access to the web resource works correctly when on the server’s console.* No clients can access the servers data via URL.* The server does not have a firewall configured* No ACLs are preventing connectivity from the client’s network.* All services on the server are operating normally, which was confirmed by the server team.Which of the following actions will resolve the issue?  Reset port security on the switchport connecting the server.  Adjust the web server’s NTP settings to match the client settings.  Configure A records for the web server.  Install the correct MIB on the web server NEW QUESTION 151A company built a new building at its headquarters location. The new building is connected to the company’s LAN via fiber-optic cable. Multiple users in the new building are unable to access the company’s intranet site via their web browser, but they are able to access internet sites. Which of the following describes how the network administrator can resolve this issue?  Correct the DNS server entries in the DHCP scope  Correct the external firewall gateway address  Correct the NTP server settings on the clients  Correct a TFTP Issue on the company’s server NEW QUESTION 152A wireless network was installed in a warehouse for employees to scan crates with a wireless handheld scanner. The wireless network was placed in the corner of the building near the ceiling for maximum coverage However users in the offices adjacent lo the warehouse have noticed a large amount of signal overlap from the new network Additionally warehouse employees report difficulty connecting to the wireless network from the other side of the building; however they have no issues when Ihey are near the antenna Which of the following is MOST likely the cause?  The wireless signal is being refracted by the warehouse’s windows  The antenna’s power level was set too high and is overlapping  An omnidirectional antenna was used instead of a unidirectional antenna  The wireless access points are using channels from the 5GHz spectrum NEW QUESTION 153A network administrator received a report staling a critical vulnerability was detected on an application that is exposed to the internet. Which of the following Is the appropriate NEXT step?  Check for the existence of a known exploit in order to assess the risk  Immediately shut down the vulnerable application server.  Install a network access control agent on the server.  Deploy a new server to host the application. ExplanationThe appropriate next step in this situation would be to check for the existence of a known exploit in order to assess the risk. This is important because it will help the network administrator determine the severity of the vulnerability and the potential impact it could have on the organization. Once the network administrator has assessed the risk, they can then take appropriate action to address the vulnerability. This might include patching the application, deploying a new server to host the application, or implementing other security measures to mitigate the risk. It is generally not advisable to immediately shut down the vulnerable application server, as this could disrupt business operations and cause significant downtime. Similarly, installing a network access control agent on the server may not be the most effective solution, as it would not address the underlying vulnerability.NEW QUESTION 154Which of the following would be used when connecting devices that have different physical characteristics?  A proxy server  An industrial control system  A load balancer  A media converter NEW QUESTION 155Which of the following would be the MOST cost-effective recovery solution for a company’s lower-priority applications?  Warm site  Cloud site  Hot site  Cold site NEW QUESTION 156An administrator wants to increase the availability of a server that is connected to the office network.
