CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 901:

  A user reports being unable to access network resources after making some changes in the office. Which of the following should a network technician do FIRST?

  A. Check the system's IP address

  B. Do a ping test against the servers

  C. Reseat the cables into the back of the PC

  D. Ask what changes were made

  Correct Answer: D

• Question 902:

  An IT organization needs to optimize speeds for global content distribution and wants to reduce latency in high-density user locations. Which of the following technologies BEST meets the organization's requirements?

  A. Load balancing

  B. Geofencing

  C. Public cloud

  D. Content delivery network

  E. Infrastructure as a service

  Correct Answer: D

  "A CDN is a distributed network of servers that store cached copies of website content in multiple geographic locations around the world. When a user requests content, the CDN selects the server closest to the user's location to deliver the content. This results in faster delivery times and lower latency.

  Load balancing is a technique used to distribute traffic across multiple servers to improve performance and reliability. While load balancing can help optimize speeds, it does not address the issue of reducing latency in high-density user locations."

• Question 903:

  A technician is installing a high-density wireless network and wants to use an available frequency that supports the maximum number of channels to reduce interference. Which of the following standard 802.11 frequency ranges should the technician look for while reviewing WAP specifications?

  A. 2.4GHz

  B. 5GHz

  C. 6GHz

  D. 900MHz

  Correct Answer: B

  5GHz is the frequency range that supports the maximum number of channels and reduces interference in a high-density wireless network. The 802.11 standard for this range offers more non-overlapping channels, which reduces the likelihood of interference with other devices and improves overall network performance.

• Question 904:

  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

  Correct Answer: BC

• Question 905:

  Which of the following is used to track and document various types of known vulnerabilities?

  A. CVE

  B. Penetration testing

  C. Zero-day

  D. SIEM

  E. Least privilege

  Correct Answer: A

  CVE is the acronym for Common Vulnerabilities and Exposures and the link to the website is posted by EpitomeOfSalt.

• Question 906:

  A technician is configuring a network switch to be used in a publicly accessible location. Which of the following should the technician configure on the switch to prevent unintended connections?

  A. DHCP snooping

  B. Geofencing

  C. Port security

  D. Secure SNMP

  Correct Answer: C

  Port security is pretty obvious. The key word here is: "switch"

• Question 907:

  A network technician is manually configuring the network settings for a new device and is told the network block is 192.168.0.0/20. Which of the following subnets should the technician use?

  A. 255.255.128.0

  B. 255.255.192.0

  C. 255.255.240.0

  D. 255.255.248.0

  Correct Answer: C

  192.168.0.0/20 CIDR is in the third octet. /1-8 (1st octet), /9-16 (2nd octet), /17-24 (3rd octet), /25-32 (4th octet). /17 = 128 /18 = 192 /19 = 224 /20 = 240 is the answer /21 = 248 /22 = 252 /23 = 254 /24 = 255

• Question 908:

  A network engineer performs the following tasks to increase server bandwidth:

  1.

  Connects two network cables from the server to a switch stack

  2.

  Configure LACP on the switchports

  3.

  Verifies the correct configurations on the switch interfaces

  Which of the following needs to be configured on the server?

  A. Load balancing

  B. Multipathing

  C. NIC teaming

  D. Clustering

  Correct Answer: C

  In this scenario, the network engineer has connected two network cables from the server to a switch stack and configured LACP on the switchports. To take advantage of the increased bandwidth, the server needs to be configured with NIC

  teaming, which will allow it to use both network interfaces simultaneously.

  Load balancing, multipathing, and clustering are related but different techniques that may also be used to increase server performance and/or availability.

• Question 909:

  According to troubleshooting methodology, which of the following should the technician do NEXT after determining the most likely probable cause of an issue?

  A. Establish a plan of action to resolve the issue and identify potential effects

  B. Verify full system functionality and, if applicable, implement preventive measures

  C. Implement the solution or escalate as necessary

  D. Test the theory to determine the cause

  Correct Answer: D

• Question 910:

  Given the following information:

  

  Which of the following command-line tools would generate this output?

  A. netstat

  B. arp

  C. dig

  D. tracert

  Correct Answer: A
