CCNA Exam Update. Please HELP?


I am appearing for my CCNA exam on 21st. I read somewhere in a forum that whenever the Pearson VUE sites goes under maintenance, new questions are added to the CCNA pool. Currently Pearson VUE site is under maintenance. Is the information of the forum true?

Can anyone also tell me if the test engine of cisco is web based which is operated the Pearson VUE or is it a kind of desktop application or something else?

Please answer ASAP.

Thank in Advance

Pearson VUE offers innovative computer-based testing solutions through secure, electronic test delivery. Pearson VUE provides licensure and certification. It is myth that site goes under maintenance n bla bla. CCNA questions are different every time exam. so its better don’t think about it n prepare for ur exam.

Inground Pool Maintenance Questions

DTE Sand Filter Pool Maintenance Question?

I have a inground pool (15000 gallons) with a DTE Sand Filter. It seems like all pool places contradict each other.
1) Should I add the dte powder to the skimmer as I’m backflushing or vise versa? I know the sacks go inside out when you back-flush. When I added when it’s regularly on, I can see the power all over the pool floor afterwards.

2) Should I leave the pump on for 24 hours? The latest pool store said every time we shout the pump off we should backflush it. I’d rather run it for 12 hours a day, not 24.

1)you should NEVER ad D.E. powder to skimmer while backwashing it would go inside the grids and clog them…you add powder to skimmer with the valve in filter mode

2)I do not know why you need to run pump 24 hours and why you have to backwash filter every time you shut it off unless you have a green pool

you should consider a filter like this much easier: http://www.swimming-pool-information.com/sand-swimming-pool-filters.html

My Underground Pool W SAT inactive / no maintenance for 10 years and became a frog pond. How do I clean it?

He joined us in this way, if We bought our house and the owner said the previous, empty pool debris and tree, so that was adjusted for all these years. Then with a bleach mixture to the entire pool to clean from concrete. The water is not stagnant, and frogs are great guards. Can we expect? Thank you for all the answers!

1Note: The three factors here – pH, alkalinity, total and calcium hardness – all affect each other, causing it to take some trial and error to all three in the right Area to get a time. Also note that before the addition of chemicals – especially an acid – water, you must first enable the pool filter. Step2Use a water testing kit to measure calcium hardness (how "hard" or "soft" water). Calcium hardness is between 200 and 400 parts per million (ppm). Step3Following package Directions, add calcium carbonate dihydrate to increase calcium hardness to reduce sodium they add. Carefully pour the mixture of chemicals in the pool in different places, one or two feet (about one half meter) between the sides of the basin. Step4Measure total alkalinity of the water. This number should be about 80 to 150 ppm, 100 to 120 ppm is the best. Step5Adjust total alkalinity by adding sodium bicarbonate (baking soda) to increase it or reduce sodium bisulfate (dry acid). Step6With a pH tester to measure the pH of the water. The proper pH for a pool is on the order of 7.2 to 7.6. Step7To lower the pH, add sodium bisulfate or liquid hydrochloric acid. To increase, add soda (sodium carbonate). Step8Add more chemicals than necessary is that the water in balance. The treatment of Water with chlorine, granular chlorine in water in a nonmetallic container Step1Scoop according to package directions. Always wear safety glasses and rubber gloves when handling chlorine, and always of chlorine in the Water – no water to chlorine. Step2Stir for about 30 seconds and 30 minutes to solve. Step3Turn on the filter. Achieve a lot in the middle of the pool as possible (perhaps with the Standing on a diving board), pour the chlorine into the pool. Discard any sediment left in the container. Chlorine Step4Add three fifty-seven times a week for a pool in heavy Use. Step5Occasionally – no more than once a week – you need superchlorinate (also known as shock) the pool built, burn all bacteria, algae and ammonia. After the package Directions chlorine, prepare a solution for super chlorination (There will be three to five times higher than normal chlorine). Step6Add solution of chlorine in the pool after sunset if possible, that decompose the rays of the sun chlorine. Step7Before so that each go into the pool, try to ensure the residual chlorine level, it is again below 3.0 ppm. The takes at least several hours. Keep dirt and debris in the water without the basin Step1Remove leaves with a leaf net swimming as soon as you. Step2Empty sieve and rinse the skimmer or twice a week, and as often as every day during the season of dead leaves. Step3Keep deck clean by regularly sweeping and then rinsing with a garden hose. Step4Use a cover on your pool as often as possible. Step5Thoroughly Clean your pool at least once a month. Clean the filter sand against the tide: Reversing the flow of water through the filter for 2-3 minutes until it is clear that waste water. Step6For a cartridge filter, remove the cartridge out and rinse with a hose with a nozzle at high pressure. Replace the cartridge. It is what you're after, what Mike has told to do. Or just a pool boy.
