640-864 Exam Question


Which three are considered as technical constraints when identifying network requirements? (Choose three.)

A. Support for legacy applications
B. Bandwidth support for new applications
C. Limited budget allocation
D. Policy limitations
E. Limited support staff to complete assessment
F. Support for existing legacy equipment
G. Limited timeframe to implement

Correct Answer: A,B,F


Network design might be constrained by parameters that limit the solution. Legacy applications might still exist that must be supported going forward, and these applications might require a legacy protocol that may limit a design. Technical constraints include the following:
Existing wiring does not support new technology.
Bandwidth might not support new applications.
The network must support exiting legacy equipment.
Legacy applications must be supported (application compatibility).

We believe these strengths outweigh the fact that the company subdued growth in net profit had.

Highlights from the analysis by TheStreet Ratings Team go as follows: 
  • CSCO's revenue growth has slightly outpaced the industry average of 5.6%. Since the same quarter one year prior, revenues slightly increased by 1.3%. This growth in revenue does not appear to have trickled down to the company's bottom line, displayed by a decline in earnings per share.
  • The gross profit margin for CISCO SYSTEMS INC is rather high; currently it is at 65.71%. It has increased from the same quarter the previous year. Regardless of the strong results of the gross profit margin, the net profit margin of 14.92% trails the industry average.
  • Despite currently having a low debt-to-equity ratio of 0.37, it is higher than that of the industry average, inferring that management of debt levels may need to be evaluated further. Even though the debt-to-equity ratio shows mixed results, the company's quick ratio of 3.03 is very high and demonstrates very strong liquidity.
  • Looking at where the stock is today compared to one year ago, we find that it is not only higher, but it has also clearly outperformed the rise in the S&P 500 over the same period, despite the company's weak earnings results. Turning our attention to the future direction of the stock, it goes without saying that even the best stocks can fall in an overall down market. However, in any other environment, this stock still has good upside potential despite the fact that it has already risen in the past year.

B. Existing documentation and organizational input, site and network audits, traffic analysis
C. Traffic analysis, existing documentation and organizational input, site and network audits
D. Site and network audits, existing documentation and organizational input, traffic analysis

Answer : B

Explanation/Reference:Explanation:This section describes the steps necessary to characterize the existing network infrastructure and all sites. This process requires three steps:Step 1. Gather existing documentation about the network, and query the organization to discover additional information. Organization input, a network audit, and traffic analysis provide the key information you need. (Note that existing documentation may be inaccurate.)
Step 2. Perform a network audit that adds detail to the description of the network. If possible, use traffic-analysis information to augment organizational input when you are describing the applications and protocols used in the network.
Step 3. Based on your network characterization, write a summary report that describes the health of the network. With this information, you can propose hardware and software upgrades to support the network requirements and the organizational requirements.

Global Data Centre Traffic To Triple By 2018 : Cisco

Traffic data center is ready to triple online in 2018 compared to current levels, with almost half the world's population, according to a study by Cisco. Network Solutions fourth annual US giant Cisco Global Cloud Index (2013-2018) predict strong growth in workloads in the cloud and storage traffic with private cloud segment Emerging significantly higher than the public cloud.

Cisco said traffic data center study projects to triple in the next five years, almost, with the cloud that 76% of all traffic data center. In 2018, half the world's population will have residential Internet access and more than half of these users (53%) the content will be support services personal cloud storage.

The study predicts that traffic overall data center is almost three times from 2013-2018, with annual growth rate (CAGR) of 23%, from 3.1 zettabyte / year in 2013 to 8.6 zettabyte / year in 2018. a zettabyte like a trillion gigabytes company added.

The 8.6 terabytes of center traffic forecast data for 2018 is equivalent to the transmission of all movies (approximately 500,000) and TV shows (3,000,000) ever made in Ultra High Definition (UHD) 250,000 times according to the study. Global cloud traffic is growing faster than the overall traffic of global data centers.In 2013, the cloud represents 54 percent of total traffic in the data center,and in 2018, the cloud will represent 76 percent of total traffic in the data center.

The data center traffic includes traffic data center to the user along with traffic data center to data center traffic stays within data centers, he added. In 2018, 53% of all residential Internet users worldwide use storage in the personal cloud and the average traffic cloud storage to the consumer by user will be 811 megabytes per month in 2018, compared to 186 megabytes per month in 2013, according to the study by Cisco.

When people talk of the cloud, which often focus on public cloud services or services of public cloud storage. However, a significant majority of workloads in the cloud today are transformed into private cloud environment, Cisco senior VP (service provider business, products and solutions), said Kelly Ahuja.
