Part 2 Protocols and Standards Quiz

  • Question #1

  • A. Ease of configuration
  • B. Inexpensive cost
  • C. Readily available
  • D. 64 Kbps


  • Answer: A,B and C

  • Explanation:
  • Just plug into the phone line.
  • It is inexpensive.
  • Telephone lines are readily available.
  • The Public Switched Telephone Network(PSTN) typically speeds of maximum 56Kbps not 64Kbps.

  • Question #2
  • Which three are valid TCP/IP protocols?(Choose three)

  • A. SAP
  • B. TCP
  • C. HTTP
  • D. DHCP
  • E. NetBEUI


  • Answer: B, C and D

  • Explanation:
  • TCP is a transport layer protocol in the TCP/IP protocol suite.
  • HTTP is a TCP/IP protocol is the engine of WWW.
  • DHCP is a TCP/IP that automates the management of IP configuration of hosts.
  • SAP(Service Advertising Protocol) is a protocol used in Novell networks. SAP is used to advertise network services. SAP use IPX/SPX not TCP/IP.
  • NetBEUI is a legacy broadcast protocol originally from IBM. NetBEUI does not support routing and is not a member of the TCP/IP suite.

  • Question #3
  • Which layer of the OSI model is responsible for establishing, managing, and terminating communications between two computers?

  • A. session
  • B. network
  • C. physical
  • D. transport
  • E. data-link
  • F. application


  • Answer: A

  • Explanation:
  • The Session Layer controls the establishing, managing, and terminating communications sessions between presentation layers.
  • The network layer provides logical addressing for path destinations.
  • The physical layer is responsible to move bits between devices and specifies voltage, wire speed and pin-out cables.
  • The transport layer provides for both reliable and unreliable delivery and error correction before retransmit.
  • The data link layer combines bits into bytes and bytes into frames, provided access to media using MAC addresses, and error detection.
  • The application Layer is where the user/applications access the network.

  • Question #4
  • Which two make up an IPX address?(Choose two)

  • A. Subnet mask
  • B. Header prefix
  • C. MAC address
  • D. Network address


  • Answer: C and D

  • Explanation:
  • An IPX address contains 80 bits, 32 bits for the network address and 48 bits for the MAC address.

  • Question #5
  • Which method encapsulates standard PPP through a variety of media?

  • A. SSL
  • B. IPsec
  • C. L2TP
  • D. Kerberos


  • Answer: C

  • Explanation:
  • Layer Two Tunneling Protocol (L2TP) is able to encapsulate standard PPP.

  • Question #6
  • Which LAN network access security does Windows 2000 Server use?

  • A. SSL
  • B. L2TP
  • C. IPsec
  • D. Kerberos


  • Answer: D

  • Explanation:
  • Windows 2000 uses the Kerberos protocol for access security.

  • Question #7
  • Network A is IP address 192.168.100.0/24. What is a valid IP address for a computer located on network A?

  • A. 192.168.1.1
  • B. 192.167.100.10
  • C. 192.168.100.254
  • D. 192.168.100.255


  • Answer: C

  • Explanation:
  • Any valid IP address on the 192.168.100.0/24 must have the format 192.168.100.xx since the subnet mask is 24 bits. We cannot use the 192.168.100.255 address since it is reserved for broadcasts. The 192.168.100.254 address can be used however.

  • Question #8
  • The unique number stamped onto every Ethernet card ever made is known as a

  • A. Hosts Address
  • B. Serial Number
  • C. IP Address
  • D. MAC Address


  • Answer: D

  • Explanation:
  • Every Network Adapter has a unique Media Access Control (MAC)address.

  • Question #9
  • Devices within the same VLAN always belong to the same ___________.

  • A. switch
  • B. CSU/DSU
  • C. broadcast domain
  • D. Windows NT domain


  • Answer: C

  • Explanation:
  • Virtual network within a switch belongs to the same broadcast domain.

  • Question #10
  • Which protocol links addresses to physical addresses in AppleTalk?

  • A. AFP
  • B. ASP
  • C. AARP
  • D. ARAP


  • Answer: C

  • Explanation:
  • AppleTalk Address Resolution Protocol (AARP) maps AppleTalk addresses (network and node numbers) into LAN hardware addresses (for example, Ethernet or token ring addresses), and manages the process of each AppleTalk node acquiring its unique AppleTalk address on these media.

  • Question #11
  • Which authentication solution uses tickets in a heterogeneous environment with an authorization server?

  • A. SSL
  • B. L2TP
  • C. IPsec
  • D. Kerberos


  • Answer: D

  • Explanation:
  • The Kerberos security system use security tickets.

  • Question #12
  • What is the process of changing the configuration of an A,B, or C network so that it treats the network and node number differently?

  • A. routing
  • B. proxying
  • C. subnetting
  • D. reverse lookup


  • Answer: C

  • Explanation:
  • By subnetting the network into several distinct networks the address is separate into a network part and a node number(called subnet mask and host number when using TCP/IP).

  • Question #13
  • Which three communication protocols utilize a vector distance protocol to maintain routing table information?

  • A. TCP/IP
  • B. NetBEUI
  • C. IPX/SPX
  • D. AppleTalk


  • Answer: A,C, and D

  • Explanation:

  • Question #14
  • Which two LAN protocols does Windows 2000 Server natively support?

  • A. PPP
  • B. SLIP
  • C. TCP/IP
  • D. NWLINK IPX/SPX
  • E. NETBIOS

  • Answer: C and D

  • Explanation:
  • Windows 2000 Server natively supports TCP/IP, NWLINK IPX/SPX, NetBEUI etc.
