CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 781:

  Which of the following topologies requites the MOST connections when designing a network?

  A. Mesh

  B. Star

  C. Bus

  D. Ring

  Correct Answer: A

• Question 782:

  A network technician is observing the behavior of an unmanaged switch when a new device is added to the network and transmits data. Which of the following BEST describes how the switch processes this information?

  A. The data is flooded out of every port. including the one on which it came in.

  B. The data is flooded out of every port but only in the VLAN where it is located.

  C. The data is flooded out of every port, except the one on which it came in

  D. The data is flooded out of every port, excluding the VLAN where it is located

  Correct Answer: C

  The switch processes the data by flooding it out of every port, except the one on which it came in. Flooding is a process where a switch sends a data frame to all ports except the source port when it does not have an entry for the destination MAC address in its MAC address table. Flooding allows the switch to learn the MAC addresses of the devices connected to its ports and update its MAC address table accordingly. Flooding also ensures that the data frame reaches its intended destination, even if the switch does not know its location.

• Question 783:

  A firewall administrator is implementing a rule that directs HTTP traffic to an internal server listening on a non-standard socket Which of the following types of rules is the administrator implementing?

  A. NAT

  B. PAT

  C. STP

  D. SNAT

  E. ARP

  Correct Answer: B

  The firewall administrator is implementing a PAT (Port Address Translation) rule that directs HTTP traffic to an internal server listening on a non-standard socket. PAT is a type of NAT (Network Address Translation) that allows multiple devices to share a single public IP address by using different port numbers. PAT can also be used to redirect traffic from one port to another port on the same or different IP address. This can be useful for security or load balancing purposes. For example, a firewall administrator can configure a PAT rule that redirects HTTP traffic (port 80) from the public IP address of the firewall to an internal server that listens on a non-standard port (such as 8080) on its private IP address.

• Question 784:

  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

  Correct Answer: B

  The technician is just starting to look at the problem, so he is beginning to gather information to determine what the root CAUSE is. This would be step #1 Identify the Problem. "gathering information" (in this case, can certain devices be pinged on the network) is a part of step one.

• Question 785:

  An administrator notices that after contact with several switches in an MDF they failed due to electrostatic discharge. Which of the following sensors should the administrator deploy to BEST monitor static electricity conditions in the MDF?

  A. Temperature

  B. Humidity

  C. Smoke

  D. Electrical

  Correct Answer: B

• Question 786:

  To comply with an industry regulation, all communication destined to a secure server should be logged and archived on a storage device. Which of the Mowing can be configured to fulfill this requirement?

  A. QoS traffic classification

  B. Port mirroring

  C. Flow control

  D. Link Aggregation Control Protocol

  Correct Answer: B

  To comply with an industry regulation that requires all communication destined to a secure server to be logged and archived, port mirroring can be configured to fulfill this requirement.

  Port mirroring is a feature that allows a network administrator to copy or "mirror" the traffic that passes through a specific port or set of ports on a network switch to a separate port where it can be monitored or analyzed. This can be useful for a variety of purposes, including security and troubleshooting.

  In this case, the network administrator could configure port mirroring on the port or ports that are used to communicate with the secure server. This would allow the administrator to copy all the traffic destined for the secure server to a separate port, where it could be logged and archived on a storage device. Other features such as QoS traffic classification, flow control, and Link Aggregation Control Protocol (LACP) may not be directly related to this requirement.

• Question 787:

  A network technician is having issues connecting an loT sensor to the internet The WLAN settings were enabled via a custom command line, and a proper IP address assignment was received on the wireless interlace. However, when trying to connect to the internet, only HTTP redirections are being received when data Is requested. Which of the following will point to the root cause of the Issue?

  A. Verifying if an encryption protocol mismatch exists.

  B. Verifying If a captive portal is active for the WLAN.

  C. Verifying the minimum RSSI for operation in the device's documentation

  D. Verifying EIRP power settings on the access point.

  Correct Answer: B

  The root cause of the issue could be a captive portal being active for the WLAN. When a device connects to a WLAN that has a captive portal, the device is typically redirected to a login page in order to gain access to the internet. This is done by the device receiving HTTP redirections when it tries to access the internet. Therefore, verifying if a captive portal is active for the WLAN would be the most likely solution to this issue.

• Question 788:

  Which of the following use cases would justify the deployment of an mGRE hub-and-spoke topology?

  A. An Increase In network security using encryption and packet encapsulation

  B. A network expansion caused by an increase in the number of branch locations to the headquarters

  C. A mandatory requirement to increase the deployment of an SOWAN network

  D. An Improvement In network efficiency by increasing the useful packet payload

  Correct Answer: C

• Question 789:

  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

  Correct Answer: A

  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 790:

  A network technician needs to install security updates on several switches on me company's network. The management team wants this completed as quickly and efficiently as possible. Which of the following should the technician do to perform the updates?

  A. Upload the security update onto each switch using a terminal emulator and a console cable.

  B. Configure a TFTP server. SSH into each device, and perform the update.

  C. Replace each old switch with new switches that have the updates already performed.

  D. Connect a USB memory stick to each switch and perform the update.

  Correct Answer: B

  TFTP Server: Setting up a TFTP (Trivial File Transfer Protocol) server allows you to store the security update files in one location. This avoids the need to transfer files individually to each switch.

  SSH: Secure Shell (SSH) is a secure protocol used for remote access and management of network devices. SSH provides encryption and secure authentication, making it the preferred method for accessing devices remotely.
