CompTIA N10-008 Online Questions & Answers

• Question 851:

  The Chief Executive Officer of a company wants to ensure business operations are not disrupted in the event of a disaster. The solution must have fully redundant equipment, real-time synchronization, and zero data loss. Which of the following should be prepared?

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

  ---

  Explanation/Reference:

  Hot site is the most appropriate solution for the CEO's requirements. A hot site is a fully redundant data center that has all the necessary hardware, software, and data to support a company's critical business functions in the event of a disaster. The hot site is typically located in a different geographic location than the primary site to ensure business continuity in case of a natural disaster or other disruptive event. The hot site is continuously operational and has real-time data synchronization to ensure zero data loss.

  A cloud site may be a viable solution as well, as it provides automatic replication and redundancy of data and services across multiple geographic locations. However, the CEO's requirement for fully redundant equipment may not be met with a cloud site.

  A warm site is a partially configured and equipped data center that requires some setup time to become operational, so it is not an appropriate solution for zero data loss requirements.

  A cold site is a completely empty data center that requires significant setup time to become operational, making it an unsuitable solution for a CEO who wants to ensure that business operations are not disrupted.

• Question 852:

  A network engineer is installing hardware in a newly renovated data center. Major concerns that were addressed during the renovation included air circulation, building power redundancy, and the need for continuous monitoring. The network engineer is creating alerts based on the following operation specifications:

  

  A. Environmental monitoring alerts for humidity greater than 95%
  B. SIEM to parse syslog events for a failed power supply
  C. SNMP traps to report when the chassis temperature exceeds 95 (35)
  D. UPS monitoring to report when input voltage drops below 220VAC
  B. SIEM to parse syslog events for a failed power supply

• Question 853:

  Several employees have expressed concerns about the company monitoring their internet activity when they are working from home. The company wants to mitigate this issue and reassure employees that their private internet activity is not being monitored. Which of the following would satisfy company and employee needs?

  A. Split tunnel
  B. Full tunnel
  C. Site-to-site tunnel
  D. Virtual desktop
  A. Split tunnel

  ---

  Explanation/Reference:

  Split tunnel is a configuration that allows a remote user to access both the local network and the Internet at the same time. In a split tunnel configuration, only traffic destined for the corporate network is sent through the VPN tunnel, while all other traffic is sent directly to the Internet. This allows the remote user to access the Internet without the company's VPN server being able to monitor or intercept their traffic. Using a split tunnel configuration can help the company to mitigate employee concerns about internet activity being monitored and reassure employees that their private internet activity is not being monitored.

• Question 854:

  Which of the following attacks becomes more effective because of global leakages of users' passwords?

  A. Dictionary
  B. Brute-force
  C. Phishing
  D. Deauthentication
  B. Brute-force

  ---

  Explanation/Reference:

  Brute-force attacks involve trying all possible combinations of passwords until the correct one is found. Global leakages of users' passwords, such as through data breaches, provide attackers with a larger pool of potential passwords to try, making brute-force attacks more effective and potentially quicker in gaining unauthorized access to accounts or systems.

• Question 855:

  An IT technician suspects a break in one of the uplinks that provides connectivity to the core switch. Which of the following command-line tools should the technician use to determine where the incident is occurring?

  A. nslookup
  B. show config
  C. netstat
  D. show interface
  E. show counters
  D. show interface

  ---

  Explanation/Reference:

  show interface is a command-line tool that displays information about the status, configuration, and statistics of an interface on a network device. A technician can use show interface to determine where the incident is occurring in a network by checking the uplink status, speed, duplex mode, errors, collisions, and other parameters of each interface.

• Question 856:

  A network engineer needs to reduce the overhead of file transfers. Which of the following configuration changes would accomplish that goal?

  A. Link aggregation
  B. Jumbo frames
  C. Port security
  D. Flow control
  E. Lower FTP port
  B. Jumbo frames

  ---

  Explanation/Reference:

  Jumbo frames are Ethernet frames with a payload greater than the standard maximum transmission unit (MTU) of 1500 bytes. By increasing the size of the frames, more data can be transferred in a single packet, which reduces the number of packets required to transfer a large file. This reduces the overhead associated with transferring the file, such as the processing required to handle and transmit multiple packets. Jumbo frames can decrease the number of packets and thus increase the speed of file transfers.

• Question 857:

  A company hired a technician to find all the devices connected within a network. Which of the following software tools would BEST assist the technician in completing this task?

  A. IP scanner
  B. Terminal emulator
  C. NetFlow analyzer
  D. Port scanner
  A. IP scanner

  ---

  Explanation/Reference:

  IP scanners - Used to search for and detect IP addresses and other information related to devices on the network

• Question 858:

  A new user is reporting connectivity issues. Zach, the network technician, notices that there is no link light on the user's NIC. Which of the following would be used to verify the wiring back to the patch panel?

  A. Butt set
  B. Cable certifier
  C. Toner probe
  D. Snips
  B. Cable certifier

• Question 859:

  Which of the following can be used to store various types of devices and provide contactless delivery to users?

  A. Asset tags
  B. Biometrics
  C. Access control vestibules
  D. Smart lockers
  D. Smart lockers

  ---

  Explanation/Reference:

  An access control vestibule is part of a physical access control system that typically provides a space between two sets of interlocking doors. Vestibules are designed to prevent unauthorized individuals from following authorized individuals into facilities with controlled access.

• Question 860:

  The network administrator is informed that a user's email password is frequently hacked by brute-force programs. Which of the following policies should the network administrator implements to BEST mitigate this issue? (Choose two.)

  A. Captive portal
  B. Two-factor authentication
  C. Complex passwords
  D. Geofencing
  E. Role-based access
  F. Explicit deny
  B. Two-factor authentication
  C. Complex passwords
