CompTIA N10-008 Online Questions & Answers

• Question 411:

  Several users with older devices are reporting intermittent connectivity while in an outdoor patio area. After some research, the network administrator determines that an outdoor WAP might help with the issue. However, the company does not want the signal to bleed into the building and cause interference. Which of the following should the network administrator perform to BEST resolve the issue?

  A. Disable the SSID broadcast on the WAP in the patio area.
  B. Install a WAP and enable 5GHz only within the patio area.
  C. Install a directional WAP in the direction of the patio.
  D. Install a repeater on the back wall of the patio area.
  C. Install a directional WAP in the direction of the patio.

  ---

  Explanation/Reference:

  Installing a directional WAP is the best solution to provide a strong signal in the patio area without interfering with the building's Wi-Fi signal. Directional WAPs use a focused beam to provide a strong signal in a specific direction, which helps to reduce interference with neighboring Wi-Fi networks. This solution will also ensure that the signal is only available in the patio area, preventing signal bleed into the building.

• Question 412:

  A network administrator has discovered a low-end managed switch connected to the company's LAN. While reading about the device's specifications on the manufacturer's website, the administrator discovers the switch does not support a command-line interface for administration. Which of the following remote access methods should the administrator use to log in to the switch?

  A. Install a VNC plugin on the web browser.
  B. Connect to the HTTPS management interface.
  C. Replace the managed switch with an unmanaged switch.
  D. Establish an SSH session.
  B. Connect to the HTTPS management interface.

• Question 413:

  Which of the following is used to provide disaster recovery capabilities to spin up an critical devices using internet resources?

  A. Cloud site
  B. Hot site
  C. Cold site
  D. Warm site
  A. Cloud site

  ---

  Explanation/Reference:

  A cloud site is the correct answer and provides disaster recovery capabilities to spin up all critical devices using internet resources. A cloud site is a type of disaster recovery solution that allows an organization to access and use its critical systems and data in the cloud, rather than on physical servers. In the event of a disaster, an organization can use its cloud site to quickly spin up all its critical devices and continue operations using internet resources.

• Question 414:

  A network technician is installing a wireless network in an office building. After performing a site survey, the technician determines the area is very saturated on the 2.4GHz and the 5GHz bands. Which of the following wireless standards should the network technician implement?

  A. 802.11ac
  B. 802.11ax
  C. 802.11g
  D. 802.11n
  B. 802.11ax

• Question 415:

  A network technician installed a new host on the network. The host is not connecting to the company's cloud servers. The technician attemtps to ping a server using the AP address with no success. Checking the IP address using ipconfing displays:

  

  Which of the following should the technician perform NEXT to determine where the issue is located?

  A. Modify the default gateway address and ping the server to test connectivity.
  B. Change the DNS servers to be on the same subnet as the host.
  C. Modify the router's ACL to allow port 80 to exit the network.
  D. Perform a tracert command to locate where the packet is dropped.
  D. Perform a tracert command to locate where the packet is dropped.

• Question 416:

  While waking from the parking lot lo an access-controlled door an employee sees an authorized user open the door. Then the employee notices that another person catches the door before It closes and goes inside.

  Which of the following attacks Is taking place?

  A. Tailgating
  B. Pipgybacking
  C. Shoulder surfing
  D. Phisning
  A. Tailgating

  ---

  Explanation/Reference:

  The difference between piggybacking and tailgaiting is that with piggybacking, the person is willfully and intentionally letting you in. In this particular case, the person caught the door before it closed, so it is tailgating.

  Tailgating is a physical security attack that occurs when an unauthorized person follows an authorized person through a secured door or gate without their knowledge or consent. Tailgating can allow an attacker to bypass access control mechanisms and gain entry to restricted areas or resources. Tailgating can also pose a safety risk for the authorized person and other occupants of the facility. Piggybacking is a physical security attack that occurs when an unauthorized person follows an authorized person through a secured door or gate with their knowledge or consent. Piggybacking can also allow an attacker to bypass access control mechanisms and gain entry to restricted areas or resources. Piggybacking can also violate security policies and compromise the accountability of the authorized person. Shoulder surfing is a physical security attack that occurs when an unauthorized person observes or records an authorized person's confidential information, such as passwords, PINs, or credit card numbers. Shoulder surfing can allow an attacker to steal credentials and access sensitive data or systems. Shoulder surfing can also violate privacy and confidentiality rights of the authorized person. Phishing is a cyber security attack that occurs when an unauthorized person sends fraudulent emails or messages that appear to come from legitimate sources, such as banks, companies, or government agencies. Phishing can trick recipients into clicking on malicious links, opening malicious attachments, or providing personal or financial information. Phishing can allow an attacker to install malware, steal credentials, or perform identity theft. Phishing does not involve physical access to secured doors or gates.

• Question 417:

  A technician is assisting a user who cannot connect to a website. The technician attempts to ping the default gateway and DNS server of the workstation According to troubleshooting methodology this is an example of:

  A. a divide-and-conquer approach
  B. a bottom-up approach
  C. a top-to-bottom approach
  D. Implementing a solution
  B. a bottom-up approach

• Question 418:

  A network technician is troubleshooting a port channel issue. When logging in to one of the switches, the technician sees the following information displayed:

  Native VLAN mismatch detected on interface g0/1

  Which of the following layers of the OSI model is most likely to be where the issue resides?

  A. Layer 2
  B. Layer 3
  C. Layer 5
  D. Layer 6
  A. Layer 2

  ---

  Explanation/Reference:

  Layer 2 of the OSI model is the data link layer, which is responsible for transferring data between adjacent nodes on a network. It uses protocols such as Ethernet, PPP, and HDLC to encapsulate data into frames and add MAC addresses for source and destination identification. It also uses protocols such as STP, LACP, and CDP to manage the physical links and prevent loops, aggregate bandwidth, and discover neighboring devices12 A native VLAN mismatch is a common Layer 2 issue that occurs when two switches are connected by a trunk port, but have different native VLANs configured on their interfaces. A native VLAN is the VLAN that is assigned to untagged frames on a trunk port. If the native VLANs do not match, the switches will drop the untagged frames and generate an error message. This can cause connectivity problems and security risks on the network345 To resolve a native VLAN mismatch, the network technician should ensure that both switches have the same native VLAN configured on their trunk ports, or use a different port mode such as access or general.

• Question 419:

  A technician is called to a customer site because the modem has failed and needs to be replaced. The technician connects the existing firewall to a modem taken from another customer site and ensures the users can reach the Internet. That night, a remote vendor tries to transfer a file to the customer's server using FTP but is unable to make the connection. There were no issues the previous night. Which of the following is the MOST likely cause of the problem?

  A. The firewall rules in the router were not reconfigured for use with the newer ISP protocols.
  B. The modern may have its own built-in firewall that is interfering with the communications.
  C. The ISP cannot route traffic from the new modern because it came from another ISP.
  D. The NAT that converts the public IP to the internal private IP of the server is using an incorrect port.
  B. The modern may have its own built-in firewall that is interfering with the communications.
