CompTIA N10-006 Online Questions & Answers

• Question 1281:

  Which of the following is described by the MAC address FF:FF:FF:FF:FF:FF?

  A. Unicast MAC address.
  B. Invalid MAC address.
  C. Multicast MAC address.
  D. Broadcast MAC address.
  D. Broadcast MAC address.

• Question 1282:

  Which of the following switches is used with ARP to display the cache entry for a specific IP address?

  A. -a
  B. -d
  C. -g
  D. -s
  A. -a

• Question 1283:

  A technician wants to implement 802.1x. Which of the following components are required to allow an 802.11ac capable device onto the network? (Select TWO).

  A. LDAP
  B. RADIUS
  C. Access point
  D. Firewall
  E. Proxy server
  B. RADIUS
  D. Firewall

• Question 1284:

  A company is building a new 10Gb Ethernet top of rack network. Which of the following media is MOST cost-effective for this implementation?

• Question 1285:

  Which of the following is used to determine whether or not a user's account is authorized to access a server remotely?

  A. VPN
  B. RDP
  C. LDAP
  D. Encryption
  C. LDAP

• Question 1286:

  In contrast to earlier Wi-Fi speeds, which of the following BEST describes the antenna and channelization properties used in 802.11n?

  A. MIMO, DSSS
  B. MIMO, OFDM
  C. CSMA, DSSS
  D. CSMA, CDMA
  B. MIMO, OFDM

  ---

  802.11n builds upon previous 802.11 standards by adding multiple-input multiple- output (MIMO). The additional transmitter and receiver antennas allow for increased data throughput through spatial multiplexing and increased range by exploiting the spatial diversity through coding schemes like Alamouti coding. The speed is 150 Mbit/s (even 250 Mbit/s in PHY level)

• Question 1287:

  The RAID controller on a server failed and was replaced with a different brand. Which of the following will be needed after the server has been rebuilt and joined to the domain?

  A. Vendor documentation
  B. Recent backups
  C. Physical IP address
  D. Physical network diagram
  B. Recent backups

  ---

  Explanation Explanation/Reference:If the RAID controller fails and is replaced with a RAID controller with a different brand the RAID will break. We would have to rebuild a new RAID disk, access and restore the most recent backup to the new RAID disk. Note: RAID controlleris a hardware device or software program used to manage hard disk drives (HDDs) or solid-state drives (SSDs) in a computer or storage array so they work as a logical unit. In hardware-based RAID, a physical controller is used to manage the RAID array.

• Question 1288:

  A customer wants to keep cost to a minimum and has only ordered a single static IP address from the ISP. Which of the following must be configured on the router to allow for all the computers to share the same public IP address?

  A. VLANs
  B. PoE
  C. PAT
  D. VPN
  C. PAT

  ---

  Explanation Explanation/Reference:Port Address Translation (PAT), is an extension to network address translation (NAT) that permits multiple devices on a local area network (LAN) to be mapped to a single public IP address. The goal of PAT is to conserve IP addresses.

• Question 1289:

  Which of the following defines the amount of time a host retains a specific IP address before it is renewed or released?

  A. DHCP lease
  B. DNS suffix
  C. Subnet mask
  D. DHCP reservation
  A. DHCP lease

  ---

  Explanation Explanation/Reference:By default, each IP address assigned by a DHCP Server comes with a one-day lease, which is the amount of time that the address is valid.

• Question 1290:

  A network technician is troubleshooting a WAN link that traverses a 100-foot span of RG6. The technician utilizes a Time Domain Reflectometer (TDR) to proof the cable during the troubleshooting process. The TDR returns a trace that drops off suddenly at 51 feet (15.54 meters).

  Which of the following is this indicative of?

  A. Open
  B. TX/RX reverse
  C. Short
  D. Crosstalk
  A. Open
