CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 111:

  A customer hired a network consultant to provide advice on the installation of new wireless access. The customer has several devices that operate in either the 5.0GHz range or the 2.4GHz range, and the best performance must be available. Which of the following standards should the technician suggest?

  A. 802.11a

  B. 802.11b

  C. 802.11g

  D. 802.11n

  Correct Answer: D

  802.11n operates in both the 2.4GHz and 5.0GHz frequency bands, providing support for multiple-input multiple-output (MIMO) technology, which improves performance and range. It offers higher data rates and improved reliability compared to earlier standards like 802.11a, 802.11b, and 802.11g. Therefore, it would be the most suitable option for the customer's requirements.

• Question 112:

  A user is unable to navigate to a website because the provided URL is not resolving to the correct IP address. Other users are able to navigate to the intended website without issue. Which of the following is most likely causing this issue?

  A. Hosts file

  B. Self-signed certificate

  C. Nameserver record

  D. IP helper

  Correct Answer: A

• Question 113:

  A network administrator for a small office is adding a passive IDS to its network switch for the purpose of inspecting network traffic. Which of the following should the administrator use?

  A. SNMP trap

  B. Port mirroring

  C. Syslog collection

  D. API integration

  Correct Answer: B

  Port mirroring (also known as SPAN - Switched Port Analyzer) is the process of forwarding a copy of network packets from one port on a network switch to another port, where the packets can be analyzed. In this scenario, the network administrator should use port mirroring to send a copy of the network traffic to the passive IDS (Intrusion Detection System) for inspection without interrupting the normal flow of traffic on the network. This allows the IDS to monitor the network traffic and detect any suspicious or malicious activity.

• Question 114:

  When internal users attempt to access the company website, they are redirected to an inappropriate website. Which of the following is this scenario an example of?

  A. DNS poisoning

  B. On-path attack

  C. VLAN hopping

  D. ARP spoofing

  Correct Answer: A

  Domain Name System (DNS) poisoning happens when fake information is entered into the cache of a domain name server, resulting in DNS queries producing an incorrect reply, sending users to the wrong website. DNS poisoning also goes by the terms "DNS spoofing" and "DNS cache poisoning."

• Question 115:

  In order to prepare for a fire or natural disaster, a Chief Executive Officer would like the network administrator to set up a site with no equipment. Which of the following should the network administrator set up?

  A. A warm site

  C. A hot site

  D. A site provided by the ISP

  Correct Answer: B

• Question 116:

  Which of the following would allow a network administrator to analyze attacks coming from the internet without affecting latency?

  A. IPS

  B. IDS

  C. Load balancer

  D. Firewall

  Correct Answer: B

• Question 117:

  A Chief Information Officer is concerned about environmental issues in the data center at corporate headquarters. Which of the following are the most common sensors installed in a data center? (Choose two.)

  A. Carbon monoxide

  B. Air flow

  C. Flooding

  D. Humidity

  E. Electrical

  F. Temperature

  Correct Answer: DF

• Question 118:

  Which of the following is used to estimate the average life span of a device?

  A. RTO

  B. RPO

  C. MTBF

  D. MTTR

  Correct Answer: C

  MTBF (Mean Time Between Failures) is used to estimate the average life span or reliability of a device. It is a measure of how reliable a hardware product or component is, and it predicts the time between inherent failures of a system during operation. MTBF is typically used in the context of hardware components, systems, or devices to represent average time periods when the device is expected to operate without failure under specified conditions.

• Question 119:

  A technician is troubleshooting a computer issue for a user who works in a new annex of an office building. The user is reporting slow speeds and intermittent connectivity. The computer is connected via a Cat 6 cable to a distribution switch that is 492ft (150m) away. Which of the following should the technician implement to correct the issue?

  A. Increase the bandwidth allocation to the computer.

  B. Install an access switch in the annex and run fiber to the distribution switch.

  C. Run a Cat 7 cable from the computer to the distribution switch.

  D. Enable the computer to support jumbo frames.

  Correct Answer: B

• Question 120:

  An older web server on a screened subnet is serving unencrypted web traffic. The server is not capable of serving HTTPS traffic directly, but the firewall is capable of doing so. Which of the following should be done to encrypt all traffic coming into the web server from outside the network? (Choose two.)

  A. A certificate should be installed on the server.

  B. Incoming port 80 traffic at the firewall should be forwarded to port 443 on the server.

  C. Incoming port 80 traffic at the firewall should be forwarded to port 80 on the server.

  D. Incoming port 443 traffic at the firewall should be forwarded to port 80 on the server.

  E. A certificate should be installed on the firewall.

  F. A proxy server should be installed on the screened subnet.

  Correct Answer: DE
