350-701 Practice Question: Implement Zero Trust principles in their cloud…
A company wants to implement Zero Trust principles in their cloud environment. Which THREE of the following are key Zero Trust tenets?
⚠ Common exam trap
Cisco often tests the distinction between 'security controls' (like MFA) and 'core tenets' (like verify explicitly), leading candidates to incorrectly select MFA as a tenet rather than recognizing it as an implementation tool.

Correct answer & explanation
✓
Assume breach (minimize blast radius)
'Assume breach' is a core Zero Trust tenet that minimizes the blast radius by segmenting access and continuously monitoring for threats, even within the cloud environment. This principle assumes that an attacker may already be present, so it enforces micro-segmentation and real-time analytics to limit lateral movement, aligning with NIST SP 800-207 Zero Trust Architecture guidelines.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Assume breach (minimize blast radius)
Why this is correct
Design with the expectation that breach will occur, and segment accordingly.
- ✗
Implement multifactor authentication (MFA) everywhere
Why it's wrong here
While MFA is a good practice, it's not a core tenet; it's a mechanism.
- ✓
Use least privilege access
Why this is correct
Minimize access rights to reduce risk.
- ✓
Verify explicitly (authenticate and authorize every request)
Why this is correct
Zero Trust requires continuous verification of all access requests.
- ✗
Assume that the perimeter is secure
Why it's wrong here
Zero Trust assumes no implicit trust, even inside the network.
Quick reference
AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
