CloudNetX Container Networking Architecture Quiz

1. What does mTLS (mutual TLS) provide in CloudNetX service mesh?

Encrypted and authenticated communication between services

Automatic container restart on failure

Distributed logging across clusters

Resource quota enforcement per namespace

2. Which CloudNetX observability metric is most critical for diagnosing network policy issues?

Connection establishment rate and packet drop rate per policy

Container CPU utilization percentage

Image pull duration in seconds

Pod restart count over time

3. In CloudNetX container networking, what does the term 'flat network' refer to?

A single Layer 2 broadcast domain where all pods can communicate directly

A network without any security policies

A physical topology with no redundancy

A network using only IPv4 addresses

4. What is the CloudNetX mechanism for preventing network loops in multi-tier architectures?

TTL (Time To Live) and packet marking with explicit routing rules

Disabling all inter-service communication

Using only point-to-point connections

Implementing broadcast storms detection

5. In CloudNetX, how does connection draining work during pod termination?

Existing connections complete while new requests are redirected

All connections are immediately severed

Pods remain running indefinitely

Traffic is duplicated to backup pods

6. What is the primary benefit of implementing network segmentation via namespaces in CloudNetX?

Isolating workloads and applying targeted network policies per tenant

Increasing bandwidth between containers

Reducing storage requirements for container images

Simplifying DNS hostname resolution

7. Which CloudNetX networking pattern is best for gradual traffic migration between service versions?

Canary deployments with weighted load balancing

Blue-green deployment with instant cutover

Rolling updates with no traffic control

Batch migration at scheduled maintenance windows

8. In CloudNetX, what is the relationship between Services and Endpoints?

Services act as stable abstractions; Endpoints track dynamic pod IPs

Services and Endpoints are the same resource

Endpoints manage external traffic routing only

Services require manual endpoint configuration

9. How does CloudNetX handle network policy conflicts when multiple policies target the same pod?

Applies the most restrictive policy (union of deny rules)

Uses the first policy defined in the manifest

Randomly selects one policy to apply

Rejects the pod deployment entirely

10. In CloudNetX, what is the function of the eBPF (extended Berkeley Packet Filter) layer?

Kernel-level packet processing and network policy enforcement

User-space container orchestration

Database query optimization

Image registry authentication

11. In CloudNetX architecture, what is the primary function of a service mesh?

Managing inter-service communication, security, and observability

Providing physical network routing between data centers

Storing container images in a distributed registry

Handling persistent volume allocation across nodes

12. Which CloudNetX networking feature implements zero-trust security principles?

Network policies with explicit allow/deny rules

Default allow-all traffic rules

Port forwarding through SSH tunnels

Disabling TLS encryption between services

13. In CloudNetX multi-cluster networking, what problem does cross-cluster service discovery solve?

Enabling services in one cluster to communicate with services in another cluster

Reducing memory consumption in container runtimes

Automating container image scanning for vulnerabilities

Balancing CPU resources across physical servers

14. What is the primary advantage of using DNS-based service discovery in CloudNetX?

Decoupling services from direct IP dependencies and enabling dynamic scaling

Reducing the number of containers per pod

Eliminating the need for load balancers

Improving encryption at rest

15. In CloudNetX, overlay networks provide which key benefit?

Logical network isolation independent of physical infrastructure

Increased CPU performance on container hosts

Reduced latency between data centers

Simplified container image management

16. What is the purpose of a sidecar proxy in CloudNetX service mesh architecture?

Intercepting and managing traffic between microservices

Compressing container images for faster deployment

Backing up persistent data to remote storage

Scheduling workloads across availability zones

17. Which load balancing algorithm is most suitable for stateful services in CloudNetX?

Round-robin

Least connections

Source IP hash (sticky sessions)

Random selection

18. In CloudNetX, what is the role of an Ingress resource?

Exposing HTTP/HTTPS routes from outside the cluster to services

Managing internal pod-to-pod communication

Allocating storage volumes to containers

Monitoring network latency between nodes

19. Network policies in CloudNetX operate at which OSI layer?

Layer 2 (Data Link)

Layer 3 (Network) and Layer 4 (Transport)

Layer 5 (Session)

Layer 7 (Application)

20. Which component in CloudNetX is responsible for assigning IP addresses to pods?

CNI (Container Network Interface) plugin

Ingress controller

Load balancer

Service discovery daemon
