Question 1 of 445

During STP calculation, the port cost is associated with the port bandwidth by default. Which of the following statements about the relationship between port cost and port bandwidth is true?

Answer choices
Show answer

Correct answer: A

In the Spanning Tree Protocol (STP) calculation, port cost is inversely related to port bandwidth. This means that as the bandwidth of a port increases, the associated port cost decreases. Higher bandwidth ports are more efficient and desirable for network paths, hence they are assigned lower costs to prioritize them in the path selection process.

Question 2 of 445

If Proto of a route displayed in the routing table is OSPF, the preference of the route must be 10.

Answer choices
Show answer

Correct answer: A

On Huawei devices the routing table's Proto column shows OSPF only for internal OSPF routes, and with the default configuration the exam assumes those routes carry a preference of 10. OSPF external routes are displayed with the protocol O_ASE and use preference 150, so a route labelled OSPF is by definition an internal route with preference 10. The statement is therefore true.

Question 3 of 445

Which of the following protocols is not a file transfer protocol?

Answer choices
Show answer

Correct answer: D

FTP (File Transfer Protocol), TFTP (Trivial File Transfer Protocol), and SFTP (Secure File Transfer Protocol) are all protocols specifically designed for transferring files over a network. HTTP (HyperText Transfer Protocol), while used extensively for transferring web pages and data over the internet, is not primarily a file transfer protocol. Therefore, HTTP packet is not considered a file transfer protocol.

Question 4 of 445

When a switch port receives a frame that does not carry a VLAN tag, it must add a PVID to the frame.

Answer choices
Show answer

Correct answer: A

When an untagged frame arrives on a switch port, the switch tags it with the port's PVID, the port default VLAN ID, before processing it internally, so that every frame inside the switch belongs to a VLAN. The PVID is the value written into the 802.1Q tag that is added to the frame, which is what the statement describes. Frames that already carry a tag are handled according to that tag and the port's permitted VLAN list instead.

Question 5 of 445

Which of the following advantages is/are inter-VLAN route interworking in one-arm routing mode?

Answer choices
Show answer

Correct answer: A

One-arm routing, also known as router-on-a-stick, reduces the number of physical links required for inter-VLAN routing by utilizing a single physical or logical connection between the router and the switch. This single connection carries multiple VLANs' traffic, thus eliminating the need for multiple links, which is a significant advantage in network configuration.

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.
