Question 1 of 101

NAPT and Easy IP translate both IP addresses and port numbers to allow multiple private IP addresses to share multiple public IP addresses.
Answer choices
Show answer

Correct answer: A

NAPT and Easy IP use address-and-port translation to distinguish multiple private sessions sharing public connectivity. Each translated flow is identified by protocol, public IP address, and port number, allowing many internal hosts to access external networks simultaneously. Easy IP commonly selects the public address from an interface address pool or outgoing interface, while NAPT performs the port-based multiplexing.

Question 2 of 101

When a Huawei device functions as an SSH client to log in to another network device for the first time, the ssh client first-time enable command must be run to enable the first-time login function of the SSH client. Otherwise, the login fails.
Answer choices
Show answer

Correct answer: B

An SSH client on a Huawei device can establish its first connection without requiring the ssh client first-time enable command. The command controls whether the client is allowed to accept and save an unknown server host key during first-time authentication. Without it, the device can still log in if the server’s host key has already been configured or learned through another method, so first-time login does not always fail.

Question 3 of 101

AAA is short for authentication, authorization, and accounting. The accounting function records only the fees incurred when users use network resources, but not the Internet access traffic or duration.
Answer choices
Show answer

Correct answer: B

AAA accounting records more than fees. It tracks users' access to network resources, including connection time, duration, traffic volume, commands, and service usage details. These records support billing, auditing, capacity planning, and security analysis. Therefore, Internet access traffic and duration can be included in accounting information.

Question 4 of 101

R1 has the following configurations:
[R1] nat address-group test 1
[R1-address-group-test] section 1 100.1.23.1 100.1.23.254
[R1-address-group-test] mode pat
[R1-address-group-test] quit
[R1] nat-policy
[R1-policy-nat] rule name test
[R1-policy-nat-rule-test] source-address range 192.168.0.0 192.168.255.255
[R1-policy-nat-rule-test] action source-nat address-group test
[R1-policy-nat-rule-test] quit
[R1-policy-nat] quit
[R1] interface GE 0/0/2
[R1-GE0/0/2] nat enable
[R1-GE0/0/2] quit
Which of the following statements is false?
Answer choices
Show answer

Correct answer: D

PAT allows multiple internal users to share addresses from the configured NAT address group by distinguishing sessions with transport-layer port numbers. Therefore, users with different private IP addresses do not have to receive different post-NAT IP addresses. The configured pool includes 100.1.23.1 through 100.1.23.254, so 100.1.23.254 can be selected, provided traffic exits through GE0/0/2 where NAT is enabled.

Question 5 of 101

When an FTP client logs in to a Huawei network device that functions as an FTP server, which of the following commands can be used to upload a local file to the FTP server?
Answer choices
Show answer

Correct answer: C

The put command transfers a file from the FTP client’s local system to the remote FTP server, so it is used for uploading configuration files, software packages, or other local files to the Huawei device. The get command performs the opposite operation by downloading a remote server file to the local client. The dir command lists directory contents, while delete removes a file from the server.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
