Frequently asked questions

How much does the CLACC exam cost?

US$300 per attempt, or Cisco Learning Credits.

Does CLACC alone give me CCNP Collaboration?

No. CCNP Collaboration requires the core exam plus one concentration exam. Passing CLACC by itself earns a Cisco Certified Specialist credential.

What is the passing score?

Cisco does not publish passing scores or question counts; the score needed varies by exam form and is reported as pass/fail with a section breakdown.

How hard is CLACC?

It is a 90-minute professional-level exam that assumes CCNA-level knowledge plus hands-on experience with CUCM and IOS voice gateways. Candidates without real lab time usually struggle.

CLACC or another concentration?

Choose CLACC for on-premises call control; CLHCT for Webex hybrid and cloud; CLCCE for contact center.
