Exam #3: In Class, via Blackboard

To be prepared for this, and any of the exams, you must be able to answer all of the Review Questions at the end of each chapter.

This exam includes, but is not limited, to the following:

Chapter 10: Layer 2 Switching

  • What are the steps that a switch uses to build its MAC address table?
    • What will a switch do with a frame received on a port that has a destination MAC address that “is not” in the mac address-table?
    • What will a switch do with a frame received on a port that has a destination MAC address that “is” in the mac address-table?
  • Layer 2 switch functions
  • Configuring a Management IP address on a switch
  • 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?

Chapter 11: VLANs and InterVLAN Routing

  • Virtual LAN (VLAN)
    • VLAN 1 is the default Ethernet VLAN
    • VLANs 1002 through 1005 are automatically created and cannot be deleted
    • Trunking
      • What is the purpose of a Trunk port?
      • What are the Cisco IOS commands to configure an interface as a trunk port?
    • IEEE 802.1Q

Chapter 12: Security: Access Control Lists (ACL)

  • You will need to decode an ACL to determine:
    • which IP addresses or networks are being denied or allowed,
    • which protocols are being denied or allowed,
    • whether the rule applies to inboud our outbound traffic,
    • etc.
  • Standard Access Lists
    • Standard Access Lists can check for what in the IP packet?
    • Is a Standard ACL applied closest to the destination or closest to the source?
    • What are the access-list numbers for a Standard ACL?
  • Extended Access Lists
    • Extended Access Lists can check for what in the IP packet?
    • Is an Extended ACL applied closest to the destination or closest to the source?
    • What are the access-list numbers for an Extended ACL?
  • What is an Implict Deny?
  • An Inbound access list is applied to inbound packets on an interface, before being routed.
    • Why is an inbound access list applied before the packet is routed?
  • An Outbound access list is applied to outbound packets on an interface.
  • Why must an access list must be applied to an interface to be effective?
  • Configuring ACLs
    • access-list
    • access-group
    • access-class
  • Security Appliances
  • Determine the Subnet Block Sizes
    • Use the block size to determine the subnet ranges

Chapter 15: Enhanced Switched Technologies

Spanning Tree Protocol (STP)

  • Loop avoidance
  • Preventing broadcast storms
  • Convergence (on switches)
  • Name the four Spanning-Tree port states
    • Disabled is not one of the four states of STP. Disabled (technically, not a transition state). A port in the administratively disabled state does not participate in frame forwarding or STP. A port in the disabled state is virtually nonoperational.

OSI Reference Model

  • All seven layers of the OSI Reference Model

Troubleshooting Commands and syntax
