350-801 Question #49: Real Exam Question with Answer & Explanation

Question

A user forwards a corporate number to an international number. What are two methods to prevent this forwarded call? (Choose two.)

Options

• AConfigure all forced code on all router.
• BBlock international dial patterns in the SIP trunk CSS.
• CConfigure a Forced Authorization Code on the international router pattern.
• DSet the call Classification to OnNet for the international route pattern.
• ESet call forward All CSS to restrict international dial patterns.

Explanation

This question asks for two methods to prevent a user from forwarding a corporate number to an international number in a Cisco Unified Communications environment.

Common mistakes.

• A. 'Configure all forced code on all router' is vague and not a standard Cisco CUCM configuration. Forced Authorization Codes (FACs) are configured on route patterns, not generally 'on all router'.
• B. Blocking international dial patterns in the SIP trunk CSS would prevent calls from using that specific SIP trunk for international calls, but the call forward itself might still be attempted and fail at the trunk, or it might not prevent the forwarding attempt if the user's CSS for forwarding includes international access.
• D. Setting the call Classification to OnNet for an international route pattern is incorrect. International calls are typically OffNet, and this setting would likely cause routing issues or not prevent the call forward as intended.
