Question 1

How is OPEX defined?

Accepted Answer

OPEX, or operating expense, refers to the ongoing costs for running a product, business, or system, which is distinct from capital expenditures (CAPEX).

Question 2

BFD is a universal fast detection technology that can implement fast switchover, so BFD does not need to be used with other fast switching technologies.

Accepted Answer

BFD (Bidirectional Forwarding Detection) is a protocol used for rapid detection of faults in the path between two forwarding engines. It is often used in conjunction with other fast switching technologies to ensure quick switchover and maintain network stability.

Question 7

Which of the following are included in the full lifecycle guest management of the Agile Controller? (Choose all that apply.)

Accepted Answer

The full lifecycle guest management of the Agile Controller includes account registration, approval and distribution, authentication, and audit and deregistration.

Question 8

What is the multicast destination address of VRRP packets?

Accepted Answer

VRRP (Virtual Router Redundancy Protocol) uses the multicast address 224.0.0.18 for its packets.

Question 9

On the border between an enterprise network and its external network, which of the following devices is deployed at the outermost side of the enterprise network?

Accepted Answer

A Firewall (FW) is typically deployed at the outermost side of an enterprise network to control incoming and outgoing network traffic based on predetermined security rules.

Question 10

Which of the following statements regarding the physical topology monitoring function of eSight are true? (Choose all that apply.)

Accepted Answer

eSight's physical topology monitoring function includes displaying the layout and status of network elements (NEs), subnets, and links, supporting visualized monitoring of the network-wide status, showing the architecture and relationships within the network, and providing a unified entry for network monitoring to enhance operational efficiency.

Question 11

To improve Internet egress reliability, an enterprise uses multiple links to connect to different carrier networks. This mode requires attention to both the incoming and outgoing traffic paths. Otherwise, network quality may be affected.

Accepted Answer

Using multiple links for Internet egress requires managing both incoming and outgoing traffic to ensure optimal routing and avoid issues like asymmetric routing, which can affect network performance and reliability.

Question 12

Single-packet attacks indicate that an attacker controls botnet hosts to send a large number of attack packets, causing link congestion on the attacked network and system resource exhaustion.

Accepted Answer

A single-packet attack involves sending a single, specially crafted packet to exploit a vulnerability, not using multiple packets to cause congestion or resource exhaustion.

Question 13

A DHCP server allocates IP addresses to clients. Which of the following steps are required when configuring a DHCP server? (Choose three.)

Accepted Answer

To configure a DHCP server, you need to enable DHCP globally, configure a global address pool if using a global pool, and configure an interface address pool if using an interface-based pool. Option 82 is not a required step for basic DHCP configuration.

Question 14

Compared with a three-layer network architecture, a two-layer network architecture has simple topology and high data forwarding efficiency. The network architecture will transform to the two-layer architecture, and the three-layer network architecture will be gradually phased out.

Accepted Answer

A three-layer network architecture, which includes core, distribution, and access layers, is often used for scalability and manageability in larger networks. While a two-layer architecture (collapsed core) can be simpler and more efficient for smaller networks, it does not necessarily mean that three-layer architectures will be phased out, as they are still beneficial for complex and large-scale networks.

Question 15

Which of the following command is used to configure the listening address of the SDN controller?

Accepted Answer

The correct answer is A because the "openflow listening-ip" command is used to configure the listening address of the SDN controller.

Question 16

Which of the following attacks is not the network layer attack?

Accepted Answer

ARP spoofing attack occurs at the data link layer, not the network layer.

Question 17

What are the basic work process steps of SDN? (Choose three.)

Accepted Answer

The answer of What are the basic work process steps...

Question 18

Which of the following tasks need to be completed during the planning stage of a project? (Choose two.)

Accepted Answer

During the planning stage of a project, it is essential to understand the project background to ensure alignment with goals and objectives, and to clearly define the project requirements to guide the subsequent stages.

Question 19

Enterprise services have strict requirements for QoS in networks. Which of the following counters can be used to indicate network QoS? (Choose three.)

Accepted Answer

Bandwidth, delay, and jitter are key indicators of network Quality of Service (QoS). Bandwidth measures the capacity of the network, delay refers to the time it takes for data to travel from source to destination, and jitter measures the variation in packet arrival times.

Question 20

In most cases, optical power is expressed in dBm. Which of the following values in dBm is supported by most optical transceiver devices to receive and identify data?

Accepted Answer

Most optical transceiver devices are designed to receive and identify data at power levels around -10 dBm, which is a common sensitivity level for these devices.
