CST3607 Final Exam

Fall 2020 Final Exam is Thursday, Dec 17 at 8pm

(Note: This outline of the final exam may change, so check regularly for updates.)

The final exam includes, but is not limited, to the following:

Chapter 13: Network Address Translation (NAT)

Network Address Translation (NAT) allows many inside IP addresses to be represented by some smaller number of outside/public IP addresses.

Types of NAT, and how they work:

  • Static
  • Dynamic
  • Port Address Translation (PAT) a.k.a. NAT Overload
  • What type of address translation can use only one address to allow thousands of hosts to be translated globally?
  • In the following output, what type of NAT is being used? 
    ip nat pool todd-nat netmask
  • Instead of the netmask command, you can use the _____________ statement.

NAT terms

  • An inside local address is before or after translation?
  • An inside global address is before or after translation?
  • Outside Local
  • Outside Global

CCNA CCNP Training – No confusion with IP NAT Inside Outside Local Global

  • Using ACLs with NAT
    • What are the Cisco IOS commands to define the NAT ACL, and then to apply the ACL to an interface?
  • Configure and verify NAT for given network requirements
    • NAT Diagnostic Commands and output
    • Which command will show you the translation table?
    • Which command can you use to show the NAT translations as they occur on your router?
    • Which command will clear all your NAT entries from the translation table?
    • Which command can be used for troubleshooting and displays a summary of the NAT configuration, as well as counts of active translation types, and hits to an existing mapping?
    • Which commands must be used on your router interfaces before NAT will translate addresses?
    • Once you create a pool for the inside locals to use to get out to the global Internet, what is the command to allow them access to the pool?
  • Operation of IP Data Networks
    • Predict the data flow between two hosts across a network
  • Identify the basic operation of NAT
    • Purpose
    • Pool
    • Static
    • one-to-one
    • Overloading
    • Source addressing
    • One-way NAT

Chapter 14: Internet Protocol Version 6 (IPv6)

  • What are the three categories / transmission types of IPv6 addresses and how do they work?
  • What are the types of IPv6 addresses?
    • Which types of IPv6 addresses can’t be routed at all, not even within your organization/LAN?
  • Define and use IPv6 Zero Omission Rule 1 and Rule 2
  • StateLess Automatic Address Configuration (SLAAC)
  • What is the Cisco IOS command to enable IPv6 on a Cisco router?
  • OSPFv3
    • What is the command to configure OSPFv3 on a router?
      • In global configuration mode?
      • In interface configuration mode?

Chapter 15: Enhanced Switched Technologies

  • Spanning Tree Protocol (STP)
    • What is the main purpose of the Spanning Tree Protocol in a switched LAN?
    • Loop avoidance
    • Preventing broadcast storms
    • Convergence (on switches)
    • Name the four Spanning-Tree port states
      • Disabled is not one of the four states. Disabled (technically, is not a transition state). A port in the administratively disabled state doesn’t participate in frame forwarding or STP. A port in the disabled state is virtually nonoperational.
    • Bridge Protocol Data Units (BPDU)
    • Root bridge
    • Non-root bridges
    • Bridge ID
    • Port cost
    • Path cost
    • Switch Port Roles
  • How do you determine the “root bridge” of each VLAN?
  • What command shows the status of your STP network and root bridges?
  • (RSTP) Rapid Spanning Tree Protocol
  • IEEE 802.1w
  • Understand what PortFast and BPDU Guard provide
  • Understand what EtherChannel is and how to configure it
  • Know the the port specific roles that STP assigns to each port on switch/bridge, and how each functions.
    • Designated
    • Root
    • Alternate
    • Blocked port
  • Switch Port Security
    • Switch Port Violation Modes
      • Protect
      • Restrict
      • Shutdown
    • Which switch port violation modes will alert you via SNMP that a violation has occurred on a port?

Cisco IOS Diagnostic Commands

  • show ip interface brief
    • What would the “status” and “protocol” columns display if an interface was not enabled?
    • What would the “status” and “protocol” columns display when an interface is “shutdown?”
    • What would the “status” and “protocol” columns display if an Ethernet interface is enabled, and configured, but the other end of the connection was shutdown?
    • What would the “status” and “protocol” columns display if a Serial interface is enabled, and configured, but the other end of the connection was shutdown?
    • What would the “status” and “protocol” columns display if an interface is enabled, and configured, but the interface was not connected to another device?
    • What would the “status” and “protocol” columns display for a Serial DCE interface, where the clock rate was not set or was zero?
