CompTIA N10-006 Online Questions & Answers

• Question 561:

  Which of the following PDUs is used by a connectionless protocol?

  A. Frames
  B. Segments
  C. Streams
  D. Datagram
  D. Datagram

  ---

  UDP is a connectionless transport protocol that operates in the transport layer of the OSI model. UDP stands for User Datagram Protocol. PDUs (Protocol Data Units) used by UDP are known as Datagrams.

• Question 562:

  An organization wants to perform maintenance on any of its web servers without affecting the service availability during a scheduled change window. Which of the following network devices would be required to provide this functionality?

  A. Router
  B. Forward proxy
  C. Load balancer
  D. Firewall
  C. Load balancer

• Question 563:

  Which of the following protocols is used to allow multiple hosts to share a common IP address?

  A. HTTPS
  B. ARP
  C. CARP
  D. NAT
  D. NAT

• Question 564:

  Which of the following is an example of an IPv4 address?

  A. 192:168:1:55
  B. 192.168.1.254
  C. 00:AB:FA:B1:07:34
  D. ::1
  B. 192.168.1.254

  ---

  AnIPv4 address is notated as four decimal numbers each between 0 and 255 separated by dots (xxx.xxx.xxx.xxx). Each number is known as an octet as it represents eight binary bits. All four octets make up a 32-bit binary IPv4 address. In this question, 192.168.1.254 is a valid IPv4 address.

• Question 565:

  Users report that they are unable to access the production server with IP address 192.168.30.17. These users need to be provided access without changing any subnet to VLAN information. The VLANs configured on the network are listed below: Department VLAN # Subnet used Marketing 20 192.168.20.0/28 Customer Service 25 192.168.20.64/28 Finance 30 192.168.30.0/28 WHSE 35 192.168.30.16/28 Sales 40 192.168.3.16/28

  The users experiencing this issue need to be added to which of the following VLANs?

  A. 25
  B. 30
  C. 35
  D. 40
  C. 35

• Question 566:

  A large company has experienced Internet slowdowns as users have increased their use of the Internet. Which of the following can the Network Administrator use to determine the amount of bandwidth used by type of application?

  A. Network maps
  B. Traffic analysis
  C. Syslog
  D. ICMP
  B. Traffic analysis

  ---

  Explanation Explanation/Reference:By traffic analysis administrator will come to whether user are using bandwidth for right purpose or not.

• Question 567:

  A technician needs to limit the amount of broadcast traffic on a network and allow different segments to communicate with each other. Which of the following options would satisfy these requirements?

  A. Add a router and enable OSPF.
  B. Add a layer 3 switch and create a VLAN.
  C. Add a bridge between two switches.
  D. Add a firewall and implement proper ACL.
  B. Add a layer 3 switch and create a VLAN.

  ---

  We can limit the amount of broadcast traffic on a switched network by dividing the computers into logical network segments called VLANs. A virtual local area network (VLAN) is a logical group of computers that appear to be on the same LAN even if they are on separate IP subnets. These logical subnets are configured in the network switches. Each VLAN is a broadcast domain meaning that only computers within the same VLAN will receive broadcast traffic. Toallow different segments (VLAN) to communicate with each other, a router is required to establish a connection between the systems. We can use a network router to route between the VLANs or we can use a `Layer 3' switch. Unlike layer 2 switches that can only read the contents of the data-link layer protocol header in the packets they process, layer 3 switches can read the (IP) addresses in the network layer protocol header as well.

• Question 568:

  A technician notices a newly installed CAT5 cable is longer than the standard maximum length. Which of the following problems would this MOST likely cause?

  A. Split cable
  B. EMI
  C. DB loss
  D. Crosstalk
  C. DB loss

  ---

  Explanation Explanation/Reference:The maximum length for a cable segment is 100 m per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100metre length between active devices. This allows for 90metres of solid-core permanent wiring, two connectors and two stranded patch cables of 5metres, one at each end.

• Question 569:

  A user moves from one office to another. When the user logs onto their computer, it has local access to shared drives but no Internet access. A technician determines that the computer has an IP address in the wrong subnet. Which of the following is MOST likely the cause?

  A. Incorrect VLAN
  B. MTU mismatch
  C. Hijacked HOSTS file
  D. Missing routes
  A. Incorrect VLAN

• Question 570:

  A network's design includes gateways connecting an assembly-line network. The assembly-line network users specialized cabling and interfaces to allow the assembly-line robots to communicate with one another. The IP is connecting the technician workstations with which of the following network types?

  A. CSU/DSU
  B. SCADA/ICS
  C. IS-IS
  D. LAN
  B. SCADA/ICS
