CompTIA N10-008 Online Questions & Answers

• Question 331:

  An IT administrator is creating an alias to the primary customer's domain. Which of the following DNS record types does this represent?

  A. CNAME
  B. MX
  C. A
  D. PTR
  A. CNAME

  ---

  Explanation/Reference:

  A CNAME (Canonical Name) record is used in the Domain Name System (DNS) to create an alias that points to another domain name, which is often referred to as the canonical domain name. This allows you to have multiple domain names pointing to the same IP address without having to create an A record for each one. It's commonly used to associate new subdomains with an existing domain's DNS records.

• Question 332:

  A network technician is troubleshooting an area where the wireless connection to devices is poor. The technician theorizes that the signal-to-noise ratio in the area is causing the issue. Which of the following should the technician do NEXT?

  A. Run diagnostics on the relevant devices.
  B. Move the access point to a different location.
  C. Escalate the issue to the vendor's support team.
  D. Remove any electronics that might be causing interference.
  D. Remove any electronics that might be causing interference.

• Question 333:

  Users at an office site notice the wireless network is unavailable for a short period after a brownout. Which of the following technologies is MOST cost effective to sustain network equipment during a brief power event?

  A. UPS
  B. Dual power supplies
  C. Generator
  D. Redundant circuits
  C. Generator

• Question 334:

  A network technician is installing a new SOHO wireless router for a client. After configuring and securing the wireless network, the technician begins hardening the wireless router. Which of the following should the network technician do FIRST?

  A. Enable content filtering.
  B. Back up the configurations of the device.
  C. Configure an ACL for managing the device.
  D. Filter MAC addresses.
  C. Configure an ACL for managing the device.

• Question 335:

  A technician is troubleshooting intermittent connectivity on a line-of-sight wireless bridge. Which of the following tools should the technician use to determine the cause of the packet loss?

  A. Spectrum analyzer
  B. OTDR
  C. Packet sniffer
  D. Multimeter
  A. Spectrum analyzer

• Question 336:

  A network technician is observing the behavior of an unmanaged switch when a new device is added to the network and transmits data. Which of the following BEST describes how the switch processes this information?

  A. The data is flooded out of every port. including the one on which it came in.
  B. The data is flooded out of every port but only in the VLAN where it is located.
  C. The data is flooded out of every port, except the one on which it came in
  D. The data is flooded out of every port, excluding the VLAN where it is located
  C. The data is flooded out of every port, except the one on which it came in

  ---

  Explanation/Reference:

  The switch processes the data by flooding it out of every port, except the one on which it came in. Flooding is a process where a switch sends a data frame to all ports except the source port when it does not have an entry for the destination MAC address in its MAC address table. Flooding allows the switch to learn the MAC addresses of the devices connected to its ports and update its MAC address table accordingly. Flooding also ensures that the data frame reaches its intended destination, even if the switch does not know its location.

• Question 337:

  Users in a branch can access an ln-house database server, but II is taking too long to fetch records. The analyst does not know whether the Issue is being caused by network latency. Which of the following will the analyst MOST likely use to retrieve the metrics that are needed to resolve this issue?

  A. SNMP
  B. Link state
  C. Syslog
  D. QoS
  E. Traffic shaping
  A. SNMP

  ---

  Explanation/Reference:

  Traffic shaping might be how the analyst would fix the issue but the question asks most likely use to RETRIEVE THE METRICS needed to resolve. That would be SNMP traps.

• Question 338:

  A network administrator is switching to IPv6 and wants to be able to use packet-tracing software on the network to monitor traffic. The administrator wants to set up the IP addressing to include the MAC address of each machine that is connected. Which of the following should the administrator implement? (Choose two.)

  A. EUI-64
  B. RFC1819
  C. APIPA
  D. DHCPv6
  E. SLAAC
  F. CIDR
  A. EUI-64
  E. SLAAC

• Question 339:

  A desktop support department has observed slow wireless speeds for a new line of laptops using the organization's standard image. No other devices have experienced the same issue. Which of the following should the network administrator recommend troubleshooting FIRST to resolve this issue?

  A. Increasing wireless signal power
  B. Installing a new WAP
  C. Changing the protocol associated to the SSID
  D. Updating the device wireless drivers
  D. Updating the device wireless drivers

• Question 340:

  A network administrator discovers that users in an adjacent building are connecting to the company's guest wireless network to download inappropriate material. Which of the following can the administrator do to MOST easily mitigate this issue?

  A. Reduce the wireless power levels
  B. Adjust the wireless channels
  C. Enable wireless client isolation
  D. Enable wireless port security
  A. Reduce the wireless power levels

  ---

  Explanation/Reference:

  Wireless Client Isolation is a security feature that prevents wireless clients from communicating with one another. This feature is useful for guest and BYOD SSIDs adding a level of security to limit attacks and threats between devices connected to the wireless networks.

  This question I think assumes the guest network is coming from one building and not the other. For this I would Vote A (but it's a crummy question)
