Chapter 7: Intro to TCP/IP

Which TCP/IP protocol uses port 80? A. HTTP B. HTTPS C. Telnet D. POP3

HTTP

Which of the following are valid examples of IPv6 addresses? (Choose all that apply) A. 2001:odb8:3c4d:0012:0000:0000:1234:56ab B. ::ffff:coa8:173 C. 2001:db8:3c4d:12::1234:56ab D. 2001::1ab4::5468

- 2001:odb8:3c4d:0012:0000:0000:1234:56ab - ::ffff:coa8:173 - 2001:db8:3c4d:12::1234:56ab 2001::1ab4::5468 is not valid because the double colons (::) can be used only once within an address

What are two advantages that TCP has over UDP? (Choose 2) A. Acknowledged delivery B. Faster delivery C. Lower overhead D. Virtual circuits

- Acknowledged delivery - Virtual circuits

Your network is running IPv4. Which of the configuration options are mandatory for your host to communicate on the network? (Choose 2.) A. IP address B. Subnet mask C. Default gateway D. DNS server address

- IP address - Subnet mask

Which two TCP/IP protocols work at the Host-to-Host layer of the DOD model? (Choose two.) A. IP B. ARP C. TCP D. UDP

- TCP - UDP

Which of the following IP addresses would not be valid for a DNS server on the Internet? A. 10.25.11.33 B. 18.33.66.254 C. 155.118.63.11 D. 192.186.12.2

10.25.11.33 On the Internet, a DNS server needs to have a public IP address. 10.25.11.33 is a private address and would not be valid for a DNS server on the Internet.

What port does the RDP protocol work on? A. 53 B. 143 C. 389 D. 3389

3389

Which of the following protocols is responsible for resolving IP addresses to hardware addresses? A. DNS B. DHCP C. ARP D. RARP

ARP

You have just set up a network that will use the TCP/IP protocol and you want client computers to obtain IP configuration information automatically. Which type of server do you need for this? A. DNS B. DHCP C. NAT D. IP configuration server

DHCP

You are setting up a small network that will not connect to the Internet. You want computers to be able to locate each other by using hostnames. What service will do this? A. DNS B. DHCP C. FTP D. APIPA

DNS

You are manually configuring a TCP/IP host. Another administrator gives you the router's IP address. What is the TCP/IP term for this? A. Default gateway B. Subnet mask C. DNS server D. DHCP server

Default gateway

Your friend is concerned about the security of making an online purchase. What should you tell her to look for in the address bar of the web browser? A. HTTP B. HTTPS C. SSH D> TLS

HTTPS

Which of the following protocols is used for secure delivery of email? A. SMTP B. SNMP C. POP3 D. IMAP4

IMAP4

The workstations on your network are configured to use a DHCP server. One of the workstations can't communicate with other computers. Its IP address is 169.254.1.18. What could be the problem? A. The subnet mask is wrong B. It has a private IP address C. The default gateway is wrong D. It can't reach the DHCP server

It can't reach the DHCP server

Which of the following protocols was designed to access information stored in an information directory, such as employee phone books? A. FTP B. LDAP C. RDP D. CIFS

LDAP

What is the maximum number of IPv6 addresses that can be assigned to one IPv6 interface? A. One (unicast) B. Two (unicast and anycast) C. Three (unicast, anycast, and multicast) D. None of the above

None of the above An IPv6 interface is not limited in the number of addresses that it can be assigned, although there could be limitations based upon practicality.

Which of the following is an IPv6 broadcast address? A. ::1 B. FE80:: C. FF00:: D. ::FFFF E. None of the above

None of the above IPv6 does not have broadcasts. IPv6 have multicasts, which are a bit like targeted broadcasts. FF00:: is the first part of a multicast address.

Which of the following protocols is responsible for sending email? A. IMAP4 B. POP3 C. SMTP D. SNMP

SMTP

Which of the following protocols uses TCP port 23? A. Telnet B. SSH C. FTP D. DNS
