CLCOR Exam - Question 186

Should be A, because International Number is given and it should be in E164 format. Only A matches the format, and then prefixes the required digit for matching the route pattern.

Should be A, Answer B & D are wrong as CSS don't include the International_PT and Answer C is wrong as it is missing the PreDot to strip off the +

Answer A

It is a tricky question, i say Answer A. Magic word is "international number 496929810" Because both Answer A+C would trigger routepattern by later CSS and signaled number Means we have to assume international goes with +E164 and therefore enduser calls +496929810 First question is, which Calling Search space (CSS) is working for getting displayed Route pattern; it is Intl_CSS Intl_CSS is the only one with selected partition International_PT Call should go first through a TP, which then should activate/hit mentioned route pattern The route pattern could be understood by its dot, that 777011 will get stripped by predot, but this is not covered by screenshot But does not matter because routepattern will do its job and sends call to ITSP So TP should send call to RP as \+777011496929810, or RP won't be triggered.

The closest answer culd be A. However, if C had included "predot", it could be de best answer since 777 is the offnet access code and 011 is the international acces code. So, since C omit "predot" to complain the Route Pattern, A becomes the closest answer.
