Demo Questions

Question 1
In which two ways does TCP differ from UDP? (Choose two.)

  • A: TCP provides synchronized communication.
  • B: TCP segments are essentially datagrams.
  • C: TCP provides sequence numbering of packets.
  • D: TCP uses broadcast delivery.
  • E: TCP provides best effort delivery.
Correct Answer: AC
TCP differs from UDP in the following ways: TCP provides best effort delivery.
TCP provides synchronized communication. TCP segments are essentially datagrams. 
TCP provides sequence numbering of packets. TCP uses broadcast delivery.



Question 2
Which option must occur before a workstation can exchange HTTP packets with a web server?

  • A: An ICMP connection must be established between the workstation and the web server.
  • B: A UDP connection must be established between the workstation and its default gateway.
  • C: A TCP connection must be established between the workstation and its default gateway.
  • D: A UDP connection must be established between the workstation and the web server.
  • E: An ICMP connection must be established between the workstation and its default gateway.
  • F: A TCP connection must be established between the workstation and the web server.
Correct Answer: F
HTTP uses TCP port 80.

Question 3
Refer to the exhibit. 

  

A TFTP server has recently been instated in the Atlanta office. The network administrator is located in the NY office and has made a console connection to the NY router. After establishing the connection they are unable to backup the configuration file and iOS of the NY router to the TFTP server. What is the cause of this problem?

  • A: The TFTP server has an incorrect subnet mask.
  • B: The TFTP server has an incorrect IP address.
  • C: The network administrator computer has an incorrect IP address.
  • D: The NY router has an incorrect subnet mask.
Correct Answer: A
The subnet mask of the TFTP server needs to be in the same subnet as the default gateway.



Question 4
On a Cisco switch, which protocol determines if an attached VoIP phone is from Cisco or from another vendor?

  • A: CDP
  • B: RTP
  • C: UDP
  • D: TCP
Correct Answer: A
The Cisco Unified IP Phone uses CDP to communicate information such as auxiliary VLAN ID, per port power management details, and Quality of Service (QoS) configuration information with the Cisco Catalyst switch.



Question 5
Which routing protocol has the smallest default administrative distance?

  • A: IBGP
  • B: OSPF
  • C: IS-IS
  • D: EIGRP
  • E: RIP
Correct Answer: D

Question 6
Which two statements describe the IP address 10.16.3.65/23? (Choose two.)

  • A: The lowest host address in the subnet is 10.16.2.1 255.255.254.0.
  • B: The last valid host address in the subnet is 10.16.2.254 255.255.254.0.
  • C: The network is not subnetted.
  • D: The broadcast address of the subnet is 10.16.3.255 255.255.254.0.
  • E: The subnet address is 10.16.3.0 255.255.254.0.
Correct Answer: AD
The mask 255.255.254.0 (/23) used with a Class A address means that there are 15 subnet bits and 9 host bits. The block size in the third octet is 2 (256 - 254). So this makes the subnets in 0, 2, 4, 6, etc., all the way to 254. The host 10.16.3.65 is in the 2.0 subnet. The next subnet is 4.0, so the broadcast address for the 2.0 subnet is 3.255. The valid host addresses are 2.1 through 3.254



Question 7
Which NTP command configures the local device as an NTP reference clock source?

  • A: ntp peer
  • B: ntp broadcast
  • C: ntp master
  • D: ntp server
Correct Answer: C



Question 8
Which RFC was created to alleviate the depletion of IPv4 public addresses?

  • A: RFC 4193
  • B: RFC 1519
  • C: RFC 1518
  • D: RFC 1918
Correct Answer: D
RFC 1918 references private IP addressing schemes such as NAT. RFC 1518 simply covers the usage of CIDR, or how to use address blocks more efficiently while RFC 1918 is specifically referred to as a stopgap to avert the crisis of IPv4 addresses.



Question 9
A workstation has just resolved a browser URL to the IP address of a server. Which protocol will the workstation now use to determine the destination MAC address to be placed into frames directed toward the sever?

  • A: ARP
  • B: RARP
  • C: DNS
  • D: DHCP
  • E: HTTP
Correct Answer: A



Question 10
What is the default lease time for a DHCP binding?

  • A: 24 hours
  • B: 12 hours
  • C: 48 hours
  • D: 36 hours
Correct Answer: A
