CompTIA CompTIA Certifications N10-008 Questions & Answers

• Question 1191:

  A network field technician is installing and configuring a secure wireless network. The technician performs a site survey. Which of the following documents would MOST likely be created as a result of the site survey?

  A. Physical diagram

  B. Heat map

  C. Asset list

  D. Device map

  Correct Answer: B

  A heat map would most likely be created as a result of the site survey. A heat map is a graphical representation of the wireless signal strength and coverage in a given area. It can show the location of APs, antennas, walls, obstacles, interference sources, and dead zones. It can help with planning, optimizing, and troubleshooting wireless networks.

• Question 1192:

  A technician is installing multiple UPS units in a major retail store. The technician is required to keep track of all changes to new and old equipment. Which of the following will allow the technician to record these changes?

  A. Asset tags

  B. A smart locker

  C. An access control vestibule

  D. A camera

  Correct Answer: A

  Asset tags keep track of the equipment for sure. I was looking for a change log or something but that's not an option.

• Question 1193:

  A network administrator is installing a wireless network at a client's office. Which of the following IEEE 802.11 standards would be BEST to use for multiple simultaneous client access?

  A. CDMA

  B. CSMA/CD

  C. CSMA/CA

  D. GSM

  Correct Answer: C

  CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) would be the best to use for multiple simultaneous client access. CSMA/CA is the protocol used by the IEEE 802.11 standard for wireless networks. It allows multiple wireless clients to access the network simultaneously, by using carrier sensing to avoid collisions and reduce the chance of data corruption. This makes CSMA/CA ideal for wireless networks with many clients, as it provides efficient and reliable access for all clients.

• Question 1194:

  After the A record of a public website was updated, some visitors were unable to access the website. Which of the following should be adjusted to address the issue?

  A. TTL

  B. MX

  C. TXT

  D. SOA

  Correct Answer: A

  TTL (Time to Live) should be adjusted to address the issue. The TTL determines the amount of time a record remains cached on a DNS server before it is considered expired and must be retrieved again. If the TTL is set too low, it can result in visitors being unable to access the website because they are accessing a cached, outdated version of the DNS record.

• Question 1195:

  A workstation is configured with the following network details:

  

  Software on the workstation needs to send a query to the local subnet broadcast address. To which of the following addresses should the software be configured to send the query?

  A. 10.1.2.0

  B. 10.1.2.1

  C. 10.1.2.23

  D. 10.1.2.255

  E. 10.1.2.31

  Correct Answer: E

  CIDR 27 is 1111 1111.1111 1111.1111 1111.1110 0000 2^5 = 32 hosts per subnet 1st address is network address, last address is broadcast address The user address is 10.1.2.23 which means he reside in the network of 10.1.2.0 to 10.1.2.31

  10.1.2.31 is the last address in that network thus the broadcast address

• Question 1196:

  Access to a datacenter should be individually recorded by a card reader even when multiple employees enter the facility at the same time. Which of the following allows the enforcement of this policy?

  A. Motion detection

  B. Access control vestibules

  C. Smart lockers

  D. Cameras

  Correct Answer: B

  Access control vestibules can ensure that each individual's entry into the datacenter is separately recorded by a card reader, even when multiple employees enter the facility at the same time. Access control vestibules are small rooms with two doors that require authorized individuals to present their access cards to enter or exit. The vestibules ensure that only authorized individuals enter the datacenter, and their entry is individually recorded by the card reader. Once the first door is closed, the employee must present their card again to enter the second door. This double-entry system ensures that access to the datacenter is controlled and recorded accurately.

• Question 1197:

  Which of the following would need to be configured to ensure a device with a specific MAC address is always assigned the same IP address from DHCP?

  A. Scope options

  B. Reservation

  C. Dynamic assignment

  D. Exclusion

  E. Static assignment

  Correct Answer: B

• Question 1198:

  Which of the following systems would MOST likely be found in a screened subnet?

  A. RADIUS

  B. FTP

  C. SQL

  D. LDAP

  Correct Answer: B

  DMZ - a permiter network that protects an organisations internal local area network from untrusted traffic. Typically this is a subnet where you will place all your public facing servers eg: email server, web server and file server.

• Question 1199:

  A store owner would like to have secure wireless access available for both business equipment and patron use. Which of the following features should be configured to allow different wireless access through the same equipment?

  A. MIMO

  B. TKIP

  C. LTE

  D. SSID

  Correct Answer: D

  The feature that should be configured to allow different wireless access through the same equipment is SSID (Service Set Identifier). SSID is a unique identifier that allows wireless devices to connect to a wireless network. By configuring multiple SSIDs, the store owner can provide separate wireless access for business equipment and patron use, while using the same wireless access points

• Question 1200:

  A technician is connecting multiple switches to create a large network for a new office. The switches are unmanaged Layer 2 switches with multiple connections between each pair. The network is experiencing an extreme amount of latency. Which of the following is MOST likely occurring?

  A. Ethernet collisions

  B. A DDoS attack

  C. A broadcast storm

  D. Routing loops

  Correct Answer: C

  Broadcast storm as the switches are unmanaged.
