CompTIA N10-008 Online Practice Questions and Exam Preparation

CompTIA N10-008 Online Questions & Answers

• Question 101:

  A user reports being unable to access network resources after making some changes in the office. Which of the following should a network technician do FIRST?

  A. Check the system's IP address
  B. Do a ping test against the servers
  C. Reseat the cables into the back of the PC
  D. Ask what changes were made
  D. Ask what changes were made

• Question 102:

  A security engineer wants to provide a secure, dedicated, alternate access method into an IT network infrastructure to administer connected devices and IT assets. Which of the following is the engineer most likely to implement?

  A. Remote desktop gateway
  B. Authentication and authorization controls
  C. Out-of-band management
  D. Secure Shell
  C. Out-of-band management

  ---

  Explanation/Reference:

  Out-of-band management is a method of accessing network devices and IT assets through a dedicated channel that is separate from the normal data traffic. This provides a secure and alternate way to administer the network infrastructure, especially in case of failures or emergencies. Remote desktop gateway is a service that allows remote access to desktops and applications on a network. Authentication and authorization controls are mechanisms that verify the identity and permissions of users and devices on a network. Secure Shell is a protocol that encrypts the communication between a client and a server on a network.

• Question 103:

  A network technician is troubleshooting a connection issue and determines the domain name resolution is not getting out past the firewall. Which of the following ports should the technician check to see if it is being blocked by the ACLs?

  A. 23
  B. 53
  C. 110
  D. 389
  B. 53

• Question 104:

  Which of the following uses the destination IP address to forward packets?

  A. A bridge
  B. A Layer 2 switch
  C. A router
  D. A repeater
  C. A router

  ---

  Explanation/Reference:

  A router is a device that uses the destination IP address to forward packets between different networks. A bridge and a Layer 2 switch operate at the data link layer and use MAC addresses to forward frames within the same network. A repeater is a device that amplifies or regenerates signals at the physical layer

• Question 105:

  A network technician for a bank configured a WLAN that provides good coverage. Bank employees are now reporting Wi-Fi issues when the microwave in the lunch room area is used. Which of the following frequencies should the technician use to minimize interference?

  A. 2.4GHz
  B. 5MHz
  C. 5GHz
  D. 700MHz
  C. 5GHz

• Question 106:

  Which of the Mowing architectures reduces network latency by enforcing a limit on the number of switching devices on the frame's path between any internal hosts?

  A. Spine and leaf
  B. Software-defined network
  C. Three-tiered
  D. Collapsed core
  A. Spine and leaf

  ---

  Explanation/Reference:

  It does this by using a two-level hierarchy of switches, where the spine switches connect to the leaf switches, which in turn connect to the end hosts. This reduces the number of hops a packet must take from one host to another, thus reducing latency. According to the CompTIA Network+ N10-008 Exam Guide, the Spine and Leaf topology is a modern architecture that is used to reduce latency in large networks.

• Question 107:

  An auditor assessing network best practices was able to connect a rogue switch into a network Jack and get network connectivity. Which of the following controls would BEST address this risk?

  A. Activate port security on the switchports providing end user access.
  B. Deactivate Spanning Tree Protocol on network interfaces that are facing public areas.
  C. Disable Neighbor Resolution Protocol in the Layer 2 devices.
  D. Ensure port tagging is in place for network interfaces in guest areas
  A. Activate port security on the switchports providing end user access.

  ---

  Explanation/Reference:

  Activate port security on the switchports providing end user access would BEST address the risk of a rogue switch being connected to the network. Port security limits the number of devices that can connect to a particular switchport, thereby preventing unauthorized devices from connecting to the network. By limiting the number of MAC addresses allowed on each switchport, the network administrator can help prevent rogue devices from connecting and potentially causing security issues.

• Question 108:

  A network administrator needs to create a way to redirect a network resource that has been on the local network but is now hosted as a SaaS solution. Which of the following records should be used to accomplish the task?

  A. TXT
  B. AAA
  C. PTR
  D. CNAME
  D. CNAME

  ---

  Explanation/Reference:

  CNAME stands for Canonical Name, and it is a type of DNS record that creates an alias for another domain name. A CNAME record can be used to redirect a network resource that has been moved to a different location, such as a SaaS solution. For example, if a web server that was previously hosted on the local network with the domain name www.example.com is now hosted by a SaaS provider with the domain name www.saasprovider.com, a CNAME record can be created to point www.example.com to www.saasprovider.com. This way, the users can still access the web server using the original domain name, and the DNS server will resolve it to the new domain name.

• Question 109:

  Which of the following attacks can be effectively protected against by using techniques to check if a connection was made by a human user? (Choose two.)

  A. Brute-force
  B. Dictionary
  C. On-path attack
  D. Phishing
  E. Shoulder surfing
  F. Evil twin
  A. Brute-force
  B. Dictionary

• Question 110:

  Which of the following is most likely to have the HIGHEST latency while being the most accessible?

  A. Satellite
  B. DSL
  C. Cable
  D. 4G
  A. Satellite

  ---

  Explanation/Reference:

  Satellite is most likely to have the HIGHEST latency while being the most accessible. While satellite internet may be available in remote or rural areas where other options like DSL or cable are not available, the signal has to travel long distances to reach the satellite in orbit and then back down to Earth, resulting in high latency.
