Question 1mediumdrag order
Full question →Question 1,831 of 2,015
Quick Answer
The correct order for Docker bridge networking steps is: create the bridge network, run a container attached to that bridge, assign an IP from the bridge subnet, configure port mapping for external access, and finally have the container communicate over the bridge. This sequence is correct because bridge mode relies on a virtual Ethernet bridge that isolates container traffic within a private subnet, requiring the network to exist first before a container can join it and receive an IP. On the ENCOR 350-401 exam, this drag-and-drop task tests your understanding of how Docker implements Layer 2 isolation and NAT for containerized applications, often appearing alongside questions about overlay networks or host networking. A common trap is placing port mapping before IP assignment, but remember that mapping ports to a container’s IP only makes sense after the IP is allocated. Memory tip: think “Create, Connect, IP, Map, Talk” to lock in the five-step flow.

This 350-401 practice question tests your understanding of virtual machines and hypervisors. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Correct answer & explanation
✓
Create Docker bridge network
Bridge networking starts with creating a Docker bridge network. Then, a container is run attached to that bridge. Next, the container gets an IP from the bridge subnet. After that, port mapping is configured for external access. Finally, the container communicates with others via the bridge.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
Real-world example
How this comes up in practice
A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
What to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 350-401 subnetting questions on CIDR, address ranges, and subnet selection.
