Question 1hardmulti select
Full question →hardmulti selectObjective-mapped
A development team runs multiple customer workloads in a shared Kubernetes cluster. Security wants to reduce the risk that one compromised container can read another team's data or deploy an altered image. Which three actions best improve the design? Select three.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Require signed, scanned images from an approved registry before deployment.
Image signing and scanning help ensure the cluster only deploys trusted builds that have been checked for known vulnerabilities. Using an approved registry adds supply-chain control and reduces the chance of pulling tampered or unreviewed images. This directly addresses the risk of altered or unsafe container content entering production.
B
Distractor review
Run each container as root so file permissions inside the container do not block apps.
Running containers as root increases the impact of a compromise and weakens isolation. It is easier for attackers to abuse privileged processes or escape into host resources when applications run with unnecessary rights. The goal is to reduce privilege, not expand it for convenience.
C
Best answer
Use namespaces and network policies to separate the workloads by trust zone.
Namespaces and network policies provide logical separation inside a shared cluster, which is essential when multiple teams or customers coexist. They help prevent one workload from freely reaching another workload's services or data. This is the container equivalent of segmentation and supports tenant isolation.
D
Distractor review
Mount the host filesystem into every pod so support staff can troubleshoot more quickly.
Mounting the host filesystem into pods greatly expands the damage a compromised container can do. It also creates unnecessary access to host resources and sensitive paths. Troubleshooting convenience is not worth the security tradeoff in a shared environment.
E
Best answer
Run containers with the minimum Linux capabilities and a read-only root filesystem where possible.
Dropping capabilities and using a read-only root filesystem reduce what an attacker can do even if a container is compromised. These settings limit privilege escalation paths and make persistent tampering harder. They are practical hardening controls that align with least privilege and stronger containment.
Common exam trap
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Technical deep dive
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Authentication checks who the user is.
What is the correct answer to this question?
The correct answer is: Require signed, scanned images from an approved registry before deployment. — Shared clusters need both supply-chain protections and runtime isolation. Signed, scanned images help ensure only trusted code is deployed. Namespaces and network policies separate workloads so one tenant cannot easily reach another. Running with minimal capabilities and a read-only filesystem reduces the impact of compromise even further. Together, these controls address untrusted images, lateral movement, and container breakout risk. Why others are wrong: Running as root and mounting the host filesystem both give attackers more power than they should have. Those choices make compromise more damaging and weaken tenant isolation. The correct answers all reduce privilege, separate trust boundaries, or verify image integrity before deployment.
