CompTIA N10-006 Online Questions & Answers

• Question 961:

  Enterprise IP routing policy is MOST clearly depicted in which of the following configuration management documents?

  A. Logical network diagrams
  B. Physical network diagrams
  C. Wiring schematics
  D. Group security role assignments
  A. Logical network diagrams

  ---

  Explanation Explanation/Reference:A logical network diagram illustrates the network architecture of a group of interconnected computers and other devices, such as printers, modems, switches, routers, and even mobile devices. These electronic components form the physical network that provides local area network (LAN) and wide area network (WAN) access to users. Once you know the layout and you have an idea about the packet flow then your job becomes easy and you can create an action plan to go for the implementation.

• Question 962:

  Which of the following a network technician would use to reverse engineer malware and virus?

  A. IDS
  B. VLAN
  C. Virtual Machine
  D. Switch
  C. Virtual Machine

  ---

  Virtual Machine --- even if the VM gets infected, host machine will run as normal.

• Question 963:

  A company has attempted to introduce a new major network segment to allow growth in capacity. On the core switch, a GBIC was used to interconnect with a newly placed downstream distribution switch for the first time. Soon after this implementation, a network flood and an outage occurred between the core and new distribution network modules. Which of the following should the network administrator troubleshoot FIRST in order to rectify the issue?

  A. Check for switching loops between core and distribution switches.
  B. Check whether an incorrect VLAN has been assigned to the new distribution switch.
  C. Check for inconsistent or missing routes between the core and distribution switches.
  D. Check whether the GBIC was set to multi-mode instead of single-mode SFP.
  A. Check for switching loops between core and distribution switches.

• Question 964:

  A network administrator is setting up a web server that will host a web application. Which of the following ports must be open to provide for secured and unsecured access to that front end? (Select TWO).

  A. 22
  B. 25
  C. 80
  D. 443
  E. 8080
  C. 80
  D. 443

• Question 965:

  A company has implemented a major network upgrade, replacing all the switches and printers. Which of the following is the LAST step in the change management process?

  A. Document network configurations.
  B. Acquire approvals from management.
  C. Adhere to the announced maintenance windows.
  D. Notify all stakeholders pf changes to the plan.
  A. Document network configurations.

• Question 966:

  company wants the public to be able to connect to the wireless network with minimal security, but not be able to connect to the private internal network. Which of the following firewall rules would BEST accomplish this?

  A. Content filtering on the wireless access point
  B. Allow traffic from the wireless access point
  C. Block traffic from the wireless access point
  D. Packet filtering on the wireless access point
  C. Block traffic from the wireless access point

• Question 967:

  A technician just completed a new external website and setup access rules in the firewall.

  After some testing, only users outside the internal network can reach the site. The website responds to a ping from the internal network and resolves the proper public address. Which of the following could the technician do to fix this issue

  while causing internal users to route to the website using an internal address?

  A. Configure NAT on the firewall
  B. Implement a split horizon DNS
  C. Place the server in the DMZ
  D. Adjust the proper internal ACL
  B. Implement a split horizon DNS

  ---

  Split horizon DNS (also known as Split Brain DNS) is a mechanism for DNS servers to supply different DNS query results depending on the source of the request. This can be done by hardware-basedseparation but is most commonly done in software. In this question, we want external users to be able to access the website by using a public IP address. To do this, we would have an external facing DNS server hosting a DNS zone for the website domain. Forthe internal users, we would have an internal facing DNS server hosting a DNS zone for the website domain. The external DNS zone will resolve the website URL to an external public IP address. The internal DNS server will resolve the website URL to an internal private IP address.

• Question 968:

  Which of the following describes a smurf attack?

  A. Attack on a target using spoofed ICMP packets to flood it
  B. Intercepting traffic intended for a target and redirecting it to another
  C. Spoofed VLAN tags used to bypass authentication
  D. Forging tags to bypass QoS policies in order to steal bandwidth
  A. Attack on a target using spoofed ICMP packets to flood it

  ---

  The Smurf Attack is a distributed denial-of-service attack in which largenumbers of Internet Control Message Protocol (ICMP) packets with the intended victim's spoofed source IP are broadcast to a computer network using an IP Broadcast address. Most devices on a network will, by default, respond to this by sending a reply to the source IP address. If the number of machines on the network that receive and respond to these packets is very large, the victim's computer will be flooded with traffic. This can slow down the victim's computer to the point where it becomes impossible towork on.

• Question 969:

  At which of the following layers do frames exist? (Select TWO).

  A. OSI model Data link layer
  B. TCP/IP model Network Interface layer
  C. OSI model Physical layer
  D. OSI model Network layer
  E. TCP/IP model Internet layer
  A. OSI model Data link layer
  B. TCP/IP model Network Interface layer

  ---

  The data link layer is concerned with local delivery of frames between devices on the same LAN. Data-link frames, as these protocol data units are called, do not cross the boundaries of a local network. Inter-network routing and global addressing are higher layer functions, allowing data-link protocols to focus on local delivery, addressing, and media arbitration. In this way, the data link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium, without concern for their ultimate destination.

• Question 970:

  After repairing a computer infected with malware, a technician determines that the web browser fails to go to the proper address for some sites. Which of the following should be checked?

  A. Server host file
  B. Subnet mask
  C. Local hosts file
  D. Duplex settings
  C. Local hosts file

  ---

  Explanation Explanation/Reference:The local hosts file is a text file thatcontains hostname-to-IP address mappings. By default, host to IP address mappings that are configured in the Hosts file supersede the information in DNS. If there is an entry for a domain name in the Hosts file, then the server will not attempt to query DNS servers for that name. Instead, the IP address that is configured in the Hosts file will be used. If the IP address corresponding to a name changes and the Hosts file is not updated, you may be unable to connect to the host.
