Week 9 (April 13 – 17, 2015)

  • CompTIA Network+ Certification (requires passing the CompTIA N10-005/JK0-019 exam)




  • Your Erwin grade is the grade that will be recorded on your Erwin transcript and included in your Erwin GPA (Grade Point Average) calculation
  • WEIGHTING for the Erwin grade
    • 40 points: Average of LabSim Simulations and Exams
    • 30 points: Average of Cisco exam scores (Chapters 1, 3, 4, 8, 9)
    • 25 points: CompTIA Network+ Certification (requires passing the Network+ (N10-005/JK0-019) certification exam)
    • 5 points: LabSim Network Pro Certification (all or nothing; requires passing the Network Pro Certification exam)



  • WEIGHTING for the Cisco Academy CCNA grade
    • 75%: Chapter exams
    • 25%: Final Exam
  • NOTES for the Cisco Academy grade
    • Your Cisco Academy grade is separate from your Erwin grade (does not appear on your Erwin transcript; is not included in your Erwin GPA)
    • Students who complete the Cisco Academy with a total (overall) score of 70% or higher will receive a Cisco Academy Course Completion Certificate
    • Students who score 75% or higher on the final exam will receive a letter of merit from Cisco



  • Students may retake the CompTIA Network+ exam according to CompTIA’s Retake Policy
  • Students may retake three Cisco Exams of their choosing (including the final exam)
    • For example, a student may choose to re-take three chapter exams – or – a student may choose to re-take two chapter exams and the final exam. Either way, three is the maximum number of re-takes.

DDR SDRAM Explained

DRAM is asynchronous, meaning it operates independently of the CPU and the system bus’ clock cycle. SDRAM is synchronous, meaning its operation is dependent on the data bus’ clock cycle (as is the CPU). This synchronicity translates to faster data transfers between memory and the CPU.

SDR (Single Data Rate) SDRAM sends one bit per clock cycle. DDR (Double Data Rate) SDRAM sends two bits per clock cycle (on both the rising and the falling edges of each clock cycle). DDR2 achieves speeds twice as fast as DDR by using an internal clock that runs at double the speed.


The maximum transfer rate for a memory module can be calculated with the following formula:

Maximum Transfer Rate = (clock rate in MHz) x (number of bits) / 8 (the reason for dividing by 8 is to convert bits to Bytes)

Since DIMM modules transfer 64 bits at a time, “number of bits” will always be 64. Since 64 / 8 = 8, we can simplify this formula to:

Maximum Theoretical Transfer Rate = clock rate x 8


DDR2-400 / PC2-3200 Memory Module

Has a 400MHz clock cycle (real clock = 200MHz, doubled), so it can send/receive 400M bits per second

To determine Bandwidth (Transfer Rate), multiply:

400M (Hz) x 8 (bits) = 3200 MB/s


IPv6 Neighbor Discovery Process (IPv6 Neighbor Discovery, SLAAC, Default Gateway assignment)

IPv6 Neighbor Discovery Process

  • Determines the link-local address of a neighbor-devices (all devices on the same  link/LAN)
  • Verifies the reachability of a neighbor
  • Keeps track of neighboring devices


IPv6 Neighbor Solicitation Message

  • Sent on the local link when a node wants to determine the link-layer address of another node on the same local link (see the figure below). When a node wants to determine the link-layer address of another node, the source address in a neighbor solicitation message is the IPv6 address of the node sending the neighbor solicitation message. The destination address in the neighbor solicitation message is the solicited-node multicast address that corresponds to the IPv6 address of the destination node. The neighbor solicitation message also includes the link-layer address of the source node.





IPv6 Link-layer addresses appear to be the same as Link-local addresses (are they TECHNICALLY the same?)

Packet Tracer and Java

Packet Tracer in Cisco Academy assessments may be blocked by Java security restrictions. To ensure you can complete the Packet Tracer assessments, perform the following steps:

1a) Click the Windows Start button, then type java, then select Configure Java (the Java Control Panel appears)

1b) Click the Security tab of the Java Control Panel


1c) Click the Edit Site List button (the Exception Site List appears)


1d) Click the Add button (a new location field appears)

1e) In the Location field, enter

1f) Click the Add button (a new location field appears)

1g) In the Location field, enter

1h) Click the OK button

1h) Ensure that your Java Control Panel appears like the screenshot above (with and in the Exception Site List).

2) Go to and follow the on-screen instructions to ensure your device meets the minimum requirement needed to run assessments that contain Cisco Packet Tracer activities.
