Exam 350-801 topic 1 question 161 discussion

I`ve passed the exam yesterday, and my call control score was 100%. I answered A and C. Route and Translation patterns. My thought was like "they are asking about, where admin can block particular pattern".

If we focus on patterns only, both translation pattern & route patern have the ability to check box (block this pattern). and the answer should be A & C Also CSS and partitions are used to prevent toll fraud. the question is tricky, but it says "block the pattern" so literally A&C have this option writen on it.

You can definitely block calls through Route Pattern and Translation Pattern, but that should block legitimate calls along with toll frauds. We need to understand how the toll fraud would occur in the Telephony environment. Example would be: someone calling an extension (internal/ external) and that extension is forwarded to an international number. This should be blocked by proper Partitions and calling search spaces (CSS) designs.

A and C CSS/call privileges are used to permit or allow calls. So you can grant or deny access to certain destinations. Only the selected partitions ( dialable numbers ) would be granted. There is no Block or allow option for CSS. Route and Translation patterns on the other hand has the option to block or allow the Pattern.

Must be A & C

As per the discussing on this thread. The question is asking for "pattern" so the answer is route pattern and translation pattern

correct answer is CSS and Partition

D&E are correct. in CUCM TF can be controlled via COS. Partition and CSS are CUCM COS components. https://www.ciscopress.com/articles/article.asp?p=2218297&seqNum=10

Partition and CSS

A and C Route Option are 1-Route this pattern or 2-Block this pattern

Partition and CSSs provide segmentation and control for the number that can be called

There is a similer question ( answer is partition/CSS ) - Which two configuration elements are part of the Cisco Unified Communications Manager toll- fraud prevention? (Choose two.) A. SIP trunk security profile. B. Partition C. Calling search space D. SUBSCRIBE calling search space E. Feature control policy

It is actually very simple. you have a pattern for +1! as and your users shall use it. so now try you CSS and partition idea when asked to allow +1! however excluding +1888! numbers. Translation Pattern is choice 1 to block Route Pattern for lazy people like me who like to have it combined in one place.

CE can block calls together. Tricky question

Answer is D and E. When you attempt to make a call, Cisco CallManager looks into the CSS of the calling party and checks if the called party belongs to a partition within the CSS. If it does, the call is placed. If not, the call is rejected

I think A, C is correct they both have block pattern option,
