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: B

The statement is false. While the default preference for OSPF routes on certain devices, such as Huawei routers, is typically set to 10, this value is not fixed and can be changed by the network administrator. Therefore, the preference of the route does not have to be 10; it must not be assumed to be a constant value.

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: B

When a switch port receives a frame without a VLAN tag, the switch adds a VLAN tag to the frame with the value corresponding to the Port VLAN ID (PVID). The PVID is an attribute associated with the port itself, not with the frame. Therefore, the correct interpretation of the question is that the switch adds a VLAN tag (which carries the PVID value) to the frame, not that it adds a PVID directly to the frame. Hence, the answer is false.

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

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.

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.

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.
