CompTIA N10-008 Online Questions & Answers

• Question 151:

  A network contains 25 access points. Which of the following devices would be best to change configurations on all the devices remotely?

  A. WLAN controller
  B. Load balancer
  C. Bridge
  D. Layer 3 switch
  A. WLAN controller

  ---

  Explanation/Reference:

  A WLAN controller is a device that can centrally manage and configure multiple access points in a wireless network. A WLAN controller can change settings on all the devices remotely, such as SSIDs, security policies, firmware updates, and channel assignments. A WLAN controller can also monitor the performance and status of the access points and provide load balancing and fault tolerance

• Question 152:

  An on-call network technician receives an automated email alert stating that a power supply on a firewall has just powered down. Which of the following protocols would BEST allow for this level of detailed device monitoring?

  A. TFTP
  B. TLS
  C. SSL
  D. SNMP
  D. SNMP

• Question 153:

  A network technician performs several switch commands to enable various advanced features on the switch in the accounting department. During the configuration changes, several users from this department report connectivity issues. Which of the following logs would the network technician need to analyze to troubleshoot the connectivity issues?

  A. Router logs
  B. History logs
  C. Startup/bootup config logs
  D. Event Viewer logs
  B. History logs

• Question 154:

  A technician is troubleshooting a connectivity issue with an end user. The end user can access local network shares and intranet pages but is unable to access the internet or remote resources. Which of the following needs to be reconfigured?

  A. The IP address
  B. The subnet mask
  C. The gateway address
  D. The DNS servers
  C. The gateway address

  ---

  Explanation/Reference:

  In this scenario, the end user can access local network resources (local network shares and intranet pages) but cannot access the internet or remote resources. This indicates that the issue lies in the communication between the local network and external networks (the internet and remote resources).

  The gateway address is responsible for routing traffic between different networks. If the gateway address is misconfigured or not set correctly, it can prevent the user's device from accessing external networks. Local network resources are accessible because they are within the same network, but external resources require the gateway to be properly configured to route traffic beyond the local network.

  Therefore, the most likely cause of the issue is a misconfigured gateway address, and it needs to be reconfigured to point to the correct gateway/router for accessing external networks.

• Question 155:

  A network administrator is reviewing interface errors on a switch. Which of the following indicates that a switchport is receiving packets in excess of the configured MTU?

  A. CRC errors
  B. Giants
  C. Runts
  D. Flooding
  B. Giants

  ---

  Explanation/Reference:

  Giants are packets that exceed the configured MTU (Maximum Transmission Unit) of a switchport or interface, which causes them to be dropped or fragmented by the switch or router. The MTU is the maximum size of a packet that can be transmitted without fragmentation on a given medium or protocol. Giants can indicate misconfiguration or mismatch of MTU values between devices or interfaces on a network, which can cause performance issues or errors. CRC errors are errors that occur when the cyclic redundancy check (CRC) value of a packet does not match the calculated CRC value at the destination, which indicates corruption or alteration of data during transmission due to noise, interference, faulty cabling, etc., but not necessarily exceeding MTU values. Runts are packets that are smaller than the minimum size allowed by the medium or protocol, which causes them to be dropped or ignored by the switch or router. Flooding is a technique where a switch sends packets to all ports except the source port when it does not have an entry for the destination MAC address in its MAC address table, which can cause congestion or broadcast storms on a network.

• Question 156:

  A network technician crimped a length of UTP with TIA\EIA-568A on one end and TIA\EIA-568B on the other. Which of the following cable types did the technician create?

  A. Crossover cable
  B. Patch cable
  C. Twinaxial cable
  D. Rollover cable
  A. Crossover cable

  ---

  Explanation/Reference:

  When a network technician crimps a length of UTP (Unshielded Twisted Pair) cable with TIA/EIA-568A on one end and TIA/EIA-568B on the other, they have created a crossover cable. A crossover cable is used to connect similar devices directly, such as connecting two computers or two switches without the need for a crossover port on a hub or switch

• Question 157:

  A network technician is planning the infrastructure for a new data center that will support a 10GBASE-T network. Traffic in the data center is expected to be high, and data integrity is very important. Which of the following would the network technician most likely include in the plan?

  A. UTP plenum
  B. Cat 6a STP
  C. PoE injector
  D. Riser Cat 5e
  B. Cat 6a STP

• Question 158:

  According to troubleshooting methodology, which of the following should the technician do NEXT after determining the most likely probable cause of an issue?

  A. Establish a plan of action to resolve the issue and identify potential effects
  B. Verify full system functionality and, if applicable, implement preventive measures
  C. Implement the solution or escalate as necessary
  D. Test the theory to determine the cause
  D. Test the theory to determine the cause

• Question 159:

  Which of the following cloud components can filter inbound and outbound traffic between cloud resources?

  A. NAT gateways
  B. Service endpoints
  C. Network security groups
  D. Virtual private cloud
  C. Network security groups

  ---

  Explanation/Reference:

  Network security groups are cloud components that can filter inbound and outbound traffic between cloud resources based on rules and priorities. Network security groups can be applied to virtual machines, subnets, or network interfaces to control the network access and security. Network security groups can allow or deny traffic based on the source, destination, port, and protocol of the packets. Network security groups are different from NAT gateways, service endpoints, and virtual private clouds, which are other cloud components that have different functions and purposes.

• Question 160:

  A local firm has hired a consulting company to clean up its IT infrastructure. The consulting company notices remote printing is accomplished by port forwarding via publicly accessible IPs through the firm's firewall. Which of the following would be the MOST appropriate way to enable secure remote printing?

  A. SSH
  B. VPN
  C. Telnet
  D. SSL
  B. VPN

  ---

  Explanation/Reference:

  VPN (Virtual Private Network) is the most appropriate way to enable secure remote printing. VPN is a technology that creates a secure and encrypted tunnel over a public network such as the Internet. It allows remote users or sites to access a private network as if they were directly connected to it. VPN can be used for various purposes such as accessing corporate resources, bypassing geo-restrictions, or enhancing privacy and security. VPN can also be used for remote printing by allowing users to connect to a printer on the private network and send print jobs securely over the VPN tunnel.
