D. UDLD timers are inconsistent.

Answer: B


After reviewing UDLD status on switch ports, an engineer notices that the.” Which statement describes what this indicates about the status of the port?

A. The port is fully operational and no known issues are detected.
B. The bidirectional status of “unknown” indicates that the port will go into the disabled state because it stopped receiving UDLD packets from its neighbor.
C. UDLD moved into aggressive mode after inconsistent acknowledgements were detected.
D. The UDLD port is placed in the “unknown” state for 5 seconds until the next UDLD packet is received on the interface.

India Should Be 10% Of Our Global Revenues In 5-10 Years: Cisco CEO


US technology giant Cisco is betting heavily on digitalization initiatives in India and its local team of more than 10,000 people to boost growth, and the country is expected to represent 10 percent of its global revenues in the coming years , its CEO Chuck Robbins said.

Speaking to PTI, Robbins said: "We have seen very balanced growth in India in recent years ... When we actually started some of our initiatives 3-4 years ago, (India) was a small percentage of our business. However, it has been growing rapidly and I think that in the next 5 to 10 years, India should easily become 10 percent of our income, there is no reason why it should not, and maybe even more. "

He did not comment on the current contribution of the Indian market since the company does not divide the income of the countries.

For fiscal year 2011, the company's global revenues grew by three percent to USD 49.3 percent.

Previously, Robbins has said that India is among Cisco's largest markets along with countries such as the United States, Japan and China.

In India, Cisco is experiencing strong growth in its software business, as well as vertical security. It also points to 3X growth in its small and medium-sized enterprises (SMB), where it added 5,000 new customers in 12 months. The company has more than 10,000 people in India, including engineering and sales.

"... the adoption of the technology, the remaining broadband construction that must occur and the understanding of the technology applies in addition to that, the release of 5 G. I want to say that all these things will continue to contribute to growth. (in India) ... Any of those things, if they change, could affect that (growth), "he said.

When asked about the key elements driving Cisco's growth in India, Robbins said it is due to three things: the belief in the power of technology, both from the government and the private sector, acceleration in the Cisco's innovation efforts in the country; and his strong local team.

"And then, when you have all those things working well and a strong economy to push (operations), then what you get is good growth and that's what we've seen here (India)," he said.

Speaking about Cisco's vision for 5G technology, Robbins said his team in India will play a key role, as a market and provider for next-generation technology that promises faster Internet speeds and better connectivity between devices.


"The resources we have in India, particularly engineering resources, operate in all aspects of our technology portfolio ... people (here they are) working on many of the software capabilities that will allow architecture for 5G, will allow the delivery of services and will also allow us to really guarantee the quality of service for some of these applications, and there is also work in the hardware aspect, "he said.

We'll All Eat Crickets In 20 Years, Says Cisco's Chambers

Cisco's outgoing executive says clean, cheap insects will be our main source of protein.

Hungry? It's better to get used to eating insects, says the outgoing leader of tech giant Cisco.

"The main source of protein that you will have in your life, certainly in 20 years and maybe in 15 years, will be insects," said John Chambers, speaking at Half Moon Bay at the Techonomy conference. They are "the cleanest way to produce, at least it defies the environment".

In particular, think that eating crickets is the cat's pajamas. This vision aligns well with companies such as Aspire Food Group, which grows crickets for human consumption, and many cultures in Asia, Africa and Latin America. So maybe it's better to adopt an insectivore diet.



Chambers has been the executive director of the Cisco Systems network giant for years, but is now breaking his latest tie as chairman of the company's board. What makes you so expert in food technology? In short, he plans to become more active with startups, and pays close attention to what is happening.
Cricket growth is a high-tech operation, he says, with robots able to help crickets grow 50 percent larger in a third of the time, as usual, he said.
Chambers likes the prospects of Aspire Food Group, based in Austin, Texas, and says that cricket food is now ready. He is also an investor in the food company and mentor of CEO Mohammed Ashour, a spokesman for Aspire confirmed.
However, you will not necessarily know that you are eating small, long-legged arthropods because they can be crushed and added to other foods. He has just made a seven-course dinner at a San Francisco restaurant, Season, with crickets infused with cookies, desserts and even a margarita.
Chambers loves startups, but he worries them in the United States. France and China are doing a better job of encouraging them and making sure they are not isolated from urban coastal pockets.


 "We have become the worst," said Chambers.

And the Silicon Valley seedbed is too complacent, he added.

"When a region is disconnected from technology or from commercial or social changes, it is in danger," said Chambers. "Boston Route 128 was once the world's high-tech center," near MIT and Harvard, home to 2,000 or 3,000 high-tech companies. But the region lost the way to personal computers, software and the Internet and lost its position of influence.

"Silicon Valley has the risk of losing significant market transitions," Chambers said.
