me from United States – 04 28 2011, 7:01 PM Report Spam Some of the questions are indeed wrong, but for qualified individuals using this as a precursor to sitting the exam you will easily pick them up. Using these as your sole exam prep will make you fail.. The handful of errors are quite obvious. Solid exam prep.. Thanks.. Polly from United Kingdom – 04 19 2011, 9:00 AM Report Spam I'd be a bit wary of this one. Most of the questions are the same as in other dumps, but repeated. Also this one says some of the answers are wrong, which were correct on other dumps. my advice, use: Cisco.Certkey.640-553.v2011-02-12.by.Neal.150q.vce and http://www.securitytut.com/ for the most valid ones. string from India – 04 17 2011, 11:38 PM Report Spam hi can u tell me are these updates 2 and 3 rd the lastest dums is this same as the 2 or 3 one?
