MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security

This MLA-C01 practice question tests your understanding of ml solution monitoring, maintenance, and security. 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.

A company is deploying a SageMaker endpoint and must meet strict security requirements: no public internet access, all inter-container traffic must be encrypted, and all data at rest must be encrypted with a customer-managed KMS key. Which THREE configurations should they apply? (Choose THREE.)

A
Configure the endpoint to use VPC-only mode
VPC-only mode ensures no public internet access.
B
Attach a security group that only allows inbound traffic from the VPC CIDR
Why wrong: Security groups control inbound traffic but do not encrypt inter-container traffic or data at rest.
C
Enable inter-container traffic encryption
Encrypts communication between containers in the endpoint.
D
Specify a KMS key in the endpoint configuration for data encryption
Encrypts data at rest on the endpoint's storage.
E
Enable network isolation mode on the endpoint
Why wrong: Network isolation blocks internet access but does not encrypt inter-container traffic.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Configure the endpoint to use VPC-only mode

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.

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.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

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 MLA-C01 subnetting questions on CIDR, address ranges, and subnet selection.
