CompTIA N10-008 Online Questions & Answers

• Question 961:

  Which of the following IP transmission types encrypts all of the transmitted data?

  A. ESP
  B. AH
  C. GRE
  D. UDP
  E. TCP
  A. ESP

  ---

  Explanation/Reference:

  Encapsulating Security Payload (ESP) is a part of the IPsec suite that provides confidentiality, integrity, and authenticity to the data packets it transmits. ESP encrypts the payload of the IP packet to ensure that the transmitted data is confidential and protected from unauthorized access, making it the correct choice for encrypting all of the transmitted data.

• Question 962:

  A technician is configuring a wireless access point in a public space for guests to use. Which of the following should the technician configure so that only approved connections are allowed?

  A. Geofencing
  B. Captive portal
  C. Secure SNMP
  D. Private VLANs
  B. Captive portal

• Question 963:

  A security vendor needs to add a note to the DNS to validate the ownership of a company domain before services begin. Which of the following records did the security company MOST likely ask the company to configure?

  A. TXT
  B. AAAA
  C. CNAME
  D. SRV
  A. TXT

• Question 964:

  Which of the following firewall rules is MOST likely causing the issue?

  A. Rule 1
  B. Rule 2
  C. Rule 3
  D. Rule 4
  B. Rule 2

• Question 965:

  Wireless users have been experiencing connectivity problems. Investigation shows neighboring wireless appliances, which are not connected to the network, have been on the same 5GHz frequency to communicate. Which of the following wireless performance problem concepts defines this issue?

  A. Interference
  B. Distance limitation
  C. Signal-to-noise ratio
  D. Absorption
  A. Interference

• Question 966:

  A company's publicly accessible servers are connected to a switch between the company's ISP-connected router and the firewall in front of the company network. The firewall is stateful, and the router is running an ACL. Which of the following best describes the area between the router and the firewall?

  A. Untrusted zone
  B. Screened subnet
  C. Trusted zone
  D. Private VLAN

• Question 967:

  A medical building offers patients Wi-Fi in the waiting room. Which of the following security features would be the BEST solution to provide secure connections and keep the medical data protected?

  A. Isolating the guest network
  B. Securing SNMP
  C. MAC filtering
  D. Disabling unneeded switchports
  A. Isolating the guest network

  ---

  Explanation/Reference:

  The best solution for providing secure connections and protecting medical data in a medical building's waiting room would be to isolate the guest network. This means that the guest Wi-Fi network would be separate from the internal network, and there would be no communication between the two networks. This would help to prevent unauthorized access to the internal network and protect medical data. Other options, such as securing SNMP, MAC filtering, and disabling unneeded switchports, may also help to improve security, but they would not provide the same level of protection as isolating the guest network.

• Question 968:

  A technician wants to install a WAP in the center of a room that provides service in a radius surrounding a radio. Which of the following antenna types should the AP utilize?

  A. Omni
  B. Directional
  C. Yagi
  D. Parabolic
  A. Omni

  ---

  Explanation/Reference:

  An omni antenna should be used by the AP to provide service in a radius surrounding a radio. An omni antenna is a type of antenna that has a 360-degree horizontal radiation pattern. It can provide wireless coverage in all directions from the antenna with varying degrees of vertical coverage. It is suitable for indoor environments where users are located around the AP1.

• Question 969:

  A technician has started a major network project to upgrade to a higher throughput standard. The technician will need to install new patch panels and breakout boxes to support this inlrastructure. Which of the following layers of the OSI model is the technician addressing at this stage of the upgrade?

  A. Physical
  B. Transport
  C. Network
  D. Data link
  A. Physical

• Question 970:

  A branch of a company recently switched to a new ISP. The network engineer was given a new IP range to assign. The ISP assigned 196.26.4.0/26, and the branch gateway router now has the following configurations on the interface that peers to the ISP:

  

  The network engineer observes that all users have lost Internet connectivity. Which of the following describes the issue?

  A. The incorrect subnet mask was configured
  B. The incorrect gateway was configured
  C. The incorrect IP address was configured
  D. The incorrect interface was configured
  B. The incorrect gateway was configured

  ---

  Explanation/Reference:

  Both an incorrect subnet mask and an incorrect default gateway can cause loss of Internet connectivity. However, given the information provided:

  -

  The subnet mask is set to 255.255.255.224, but it should be 255.255.255.192 for a /26 network. This incorrect subnet mask could cause issues with routing and connectivity within the local network.

  -

  The gateway IP address is set to 196.24.4.1, which is not in the same subnet as the IP address of the interface (196.26.4.30). This could prevent the router from correctly routing traffic to and from the Internet.

  It's hard to definitively say which is the "main" cause without more information, as both could potentially lead to a loss of Internet connectivity. However, typically, an incorrect default gateway would more directly lead to a loss of Internet connectivity, as the default gateway is responsible for routing traffic between the local network and the Internet. So if forced to choose one, I would lean towards **B. The incorrect gateway was configured** as being the main cause.
