NEW QUESTION # 17
Which of the following are common VLAN link types of Ethernet switches?
- A. Mix
- B. Trunk
- C. Hybrid
- D. Access
Answer: B,C,D
Explanation:
VLAN link types define how VLAN traffic is handled on switch ports. The three common VLAN link types are:
* Access Ports :
* Used to connect end devices (e.g., PCs, printers) to the switch.
* An access port belongs to only one VLAN and carries untagged traffic for that VLAN.
* Example: A PC connected to an access port in VLAN 10 sends and receives untagged traffic.
* Trunk Ports :
* Used to connect switches or routers to carry traffic for multiple VLANs.
* Trunk ports tag traffic with VLAN IDs using IEEE 802.1Q encapsulation.
* Example: A trunk port connecting two switches carries tagged traffic for VLANs 10, 20, and 30.
* Hybrid Ports :
* A hybrid port can carry both tagged and untagged traffic.
* It is flexible and can be used for scenarios where a mix of tagged and untagged traffic is required.
* Example: A hybrid port might send untagged traffic for VLAN 10 and tagged traffic for VLAN
20.
* Mix :
* This is not a standard VLAN link type and does not exist in Ethernet switch configurations.
Thus, the correct answers are A (Trunk) , B (Access) , and C (Hybrid) .

NEW QUESTION # 19
DHCP implements centralized management of IP addresses. The DHCP server, DHCP client, and DHCP relay exchange packets to distribute key parameters, including the IP address, subnet mask, gateway, and DNS. In addition, DHCP provides a conflict detection mechanism to prevent communication failures caused by IP address conflicts.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
* DHCP Overview :
* DHCP (Dynamic Host Configuration Protocol) is used to automate the assignment of IP addresses and other network configuration parameters (e.g., subnet mask, default gateway, DNS servers).
* It centralizes IP address management, reducing manual configuration errors.
* Key Components :
* DHCP Server : Allocates IP addresses and other parameters to clients.
* DHCP Client : Requests and receives configuration from the DHCP server.
* DHCP Relay : Forwards DHCP packets between clients and servers in different subnets.
* Conflict Detection Mechanism :
* DHCP includes a mechanism to detect and resolve IP address conflicts.
* Before assigning an IP address, the DHCP server sends an ICMP Echo Request to check if the address is already in use. If no response is received, the address is considered available.
* Why TRUE?
* The statement accurately describes the functionality of DHCP, including centralized management, parameter distribution, and conflict detection.
Thus, the correct answer is A .

* HCIA Huawei ACCESS Official Documentation , Chapter: DHCP Protocol.
* RFC 2131: DHCP Protocol Specification .
NEW QUESTION # 20

NEW QUESTION # 22
Is the following description correct? The link layer defines electrical and mechanical processes and functions to activate, maintain, and remove lines when the systems at both ends are connected.
- A. True
- B. False
Answer: B
NEW QUESTION # 23
Is the following description correct? In the EPON network, in order to avoid data conflicts and improve network utilization efficiency, the downstream direction adopts TDMA multiple access mode and arbitrates the data transmission of each ONU.
- A. True
- B. False
Answer: B
NEW QUESTION # 24
The OLT supports VLAN tag translation. When the SVLANs with different attributes are used to create service flows through the service port, if tag-transform is set to default, the tag conversion rules are different.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
* VLAN Tag Translation :
* VLAN tag translation is used to modify VLAN tags in packets as they pass through the OLT.
* The tag-transform parameter determines how VLAN tags are handled during service flow creation.
* Behavior of tag-transform = default :
* When tag-transform is set to default, the OLT applies predefined rules for VLAN tag conversion based on the SVLAN (Service VLAN) attributes.
* These rules vary depending on the SVLAN type (e.g., Common, QinQ, Stacking), resulting in different behaviors.
* Why TRUE?
* The statement accurately reflects the behavior of the tag-transform parameter when set to default. Different SVLAN attributes lead to different tag conversion rules.
Thus, the correct answer is A .

NEW QUESTION # 28
Which technology is used by vectoring to cancel inter-VDSL2 line crosstalk in downstream?
- A. fdps
- B. Postponed
- C. Pre-coder
- D. Canceller
Answer: C
Explanation:
* Vectoring in VDSL2 :
* Vectoring is a technology used to mitigate crosstalk (interference between adjacent copper lines) in VDSL2 systems, improving data rates and stability.
* Crosstalk occurs when signals from one line interfere with signals on another line, especially in bundled copper cables.
* Pre-coder Technology :
* Pre-coding is a key technique used in vectoring for downstream transmission.
* It works by pre-distorting the transmitted signal at the DSLAM (Digital Subscriber Line Access Multiplexer) to cancel out the expected crosstalk at the receiver (CPE).
* This ensures that the received signal at each CPE is free from interference caused by other lines.
* Other Options :
* fdps : Not a recognized term in the context of vectoring or VDSL2.
* Canceller : While cancellation is part of vectoring, the specific term "Canceller" is not used in this context.
* Postponed : This is unrelated to vectoring or crosstalk mitigation.
* Why C?
* Pre-coding is the correct technology used in vectoring to cancel downstream crosstalk in VDSL2.
Thus, the correct answer is C .
