Final Exam Topics: CIS 3500
You are responsible for all material in Chapters 8 – 10 of the text and all material covered in
class, including subnetting, ARP, NAT and the Wireshark lab, except as noted below.
The exam may include multiple choice questions, true/false questions, fill-in-the-blank questions
and matching questions (especially for definitions). There may also be questions requiring written
responses. In various sections, you may be able to choose from among a number of question
choices. Most questions will be of low individual point value. I suggest that you review the
homework assignments as a means of preparing for the exam. Cases and articles, if any, will not
be covered. Make sure you have the latest version of the slides.
There will be problems covering the areas of subnetting, NAT and ARP (see Course
Documents/Review Exercises). In each section, you may be able to choose from among a
number of question choices. If you have not yet done the homework assignments, I recommend
you do so as a means of preparing for the exam. Make sure you have the latest version of the
slides.
Chapter 8 TCP/IP Networking I: IPv4 addressing; hierarchical addresses; dotted decimal
notation. Network, subnet and host parts. Internal and border routers. Network masks and
subnet masks. Ethernet switching vs. IP routing; routers; routing process; routing table; routing
steps; best-match row; use of mask when ones do not break at 8-bit boundary. IPv4 header (not
responsible for row 2); need for IPV6; benefits of IPv6 (not responsible for canonical
representation or IPv6 header, slides 57 - 73). TCP header; three-way handshake (also see
Section 2.10); session close. UDP header. Wireshark lab and the packet capture we studied).
Chapter 9 TCP/IP Networking II: IPv4 subnetting. Not responsible for conversion of EUI-48
addresses (§9.4). Network address translation (NAT); private addresses; loopback interface.
Address resolution protocol (ARP). In addition to understanding ARP, you should know which
protocols are used by the sender to determine its IP address, the destination’s IP address and the
router’s IP address. You should also understand how the source and destination Ethernet
addresses are determined. There will be problems involving NAT and ARP on the exam. How a
router in a network determines which subnet to deliver a packet to using the subnet mask; range
of addresses in a LAN. There will be an exam problem involving subnet addresses and subnet
masks and determining the LAN and host a packet should be routed to. DNS; domains; domain
hierarchy; domain name space, DNS database, name servers; resolvers; zones. DNS operation;
cache; DNS name resolution; not responsible for difference between iterative and recursive
queries. Unicast, multicast, broadcast and anycast addresses. Purpose of DHCP; DHCP
message exchange including use of broadcast. Not responsible for SNMP. Autonomous
systems (AS); dynamic routing protocols; interior protocols (OSPF); exterior protocols (BGP).
ICMP. IPsec; VPNs; ESP; transport and tunnel modes; purpose and use of hash; stages in IPsec
communication; IPsec vs. SSL/TLS.
Chapter 10 Carrier Wide Area Networking: Comparison of LANs, MANs and WANs. Carrier
WAN components; CPE; access links; network core; POP. The PSTN. asymmetric and
symmetric DSL; residential ADSL; DSL access multiplexer (DSLAM); DSL modem; splitter.
Cable modem service; head end; coaxial cable; FTTH. Cellular service; cell, cell site; handoff;
MTSO; frequency reuse; cellular data speeds. Leased line networks; CSU/DSU; modem; DTE,
DCE, CPE; signals; analog and digital signaling; modulation, QAM, PCM; T-carrier; SONET;
fractional T-1; bonding. Carrier WAN services; carrier Ethernet and MPLS. WAN optimization:
compression.
