NEW QUESTION 207
Which of the following descriptions about DHCP is incorrect?

The message interaction experienced by DHCP to obtain an address normally includes Discover, Offer, Request, ACK

Multiple DHCP servers are not allowed in the network at the same time, because multiple servers will respond at the same time, and the client cannot select an address

If the client abandons the current IP address, she uses a DHCP RELEASE message to notify the server, and the server reclaims this address for next use.

The Discover message between the DHCP Relay and the DHCP server is a unicast message

NEW QUESTION 208
If a PON system is considered as a black box, the external interfaces of OLTs and ONU are mainly Ethernet interfaces, and GEM encapsulation and decapsulation are performed inside the PON system.

WAHR

FALSCH

In a PON system, the OLT (Optical Line Terminal) and ONU (Optical Network Unit) use Ethernet interfaces externally to connect to the service provider’s network and end-user devices, respectively. Internally, the PON uses GEM (GPON Encapsulation Method) frames to encapsulate and decapsulate data for transmission over the optical distribution network (ODN).

NEW QUESTION 209
In the downstream direction of the GPON, all ONUs receive the same data because the broadcast mode is adopted. In the upstream direction, because the same optical splitter is used, the data of a branch fiber can also be received by another branch fiber.

WAHR

FALSCH

Downstream Transmission:
In GPON, downstream data is broadcast to all ONUs. However, each ONU only processes the data intended for it, identified by a unique identifier (ONU ID).
Upstream Transmission:
In the upstream direction, GPON uses TDMA (Time Division Multiple Access) to prevent collisions. Each ONU transmits data during its allocated time slot, and the optical splitter does not allow data from one branch fiber to interfere with another.
Why FALSE?
The second part of the statement is incorrect. Data from one branch fiber cannot be received by another branch fiber due to the TDMA mechanism and the design of the passive optical splitter.
Thus, the correct answer is B.

SNMP Overview:
SNMP (Simple Network Management Protocol) is used for managing and monitoring network devices.
TCP/IP Protocol Stack Layers:
Application Layer: Protocols that provide services directly to end users or applications (e.g., HTTP, FTP, SMTP).
Transport Layer: Protocols that ensure reliable data transfer (e.g., TCP, UDP).
Network Layer: Protocols that handle packet routing (e.g., IP).
Control Layer: Not a recognized layer in the TCP/IP model.
SNMP Placement:
SNMP operates at the Application Layer of the TCP/IP protocol stack. It uses UDP (User Datagram Protocol) as its transport protocol but resides at the application layer.
Why A?
SNMP is an application-layer protocol designed for network management tasks.
Thus, the correct answer is A.

NEW QUESTION 215
Access-layer devices are required to provide access for a large number of information terminals on both telecom networks and campus networks. Access-layer devices use various technologies. Huawei’s broadband
“access network” devices refer to the copper line access devices that mainly use the xDSL technology and the optical access devices that mainly use the PON technology.

WAHR

FALSCH

Huawei’s broadband access network devices are designed to support multiple technologies for providing connectivity to end users. These devices primarily include:
* Copper Line Access Devices : These devices use xDSL (Digital Subscriber Line) technology, which is widely used for broadband access over traditional telephone lines. Examples include ADSL, VDSL, and G.fast.
* Optical Access Devices : These devices use PON (Passive Optical Network) technology, which is a fiber-optic-based access technology. GPON (Gigabit Passive Optical Network) and XGS-PON (10- Gigabit Symmetric Passive Optical Network) are examples of PON technologies.
The statement aligns perfectly with the HCIA Huawei ACCESS documentation, which emphasizes the role of access-layer devices in supporting both copper and fiber-based technologies.

* GPON and xDSL Technology Whitepaper by Huawei.

NEW QUESTION 216
Compared with GPON, XGS-PON can cover more users and provide higher bandwidth without changing the ODN network architecture.

WAHR

FALSCH

GPON vs. XGS-PON:
GPON: Provides asymmetric bandwidth (2.5 Gbps downstream, 1.25 Gbps upstream) and supports up to 128 ONUs per PON port.
XGS-PON: Provides symmetric bandwidth (10 Gbps upstream and downstream) and supports up to 256 ONUs per PON port.
ODN Compatibility:
XGS-PON operates over the same ODN (Optical Distribution Network) as GPON, meaning no changes are required to the existing fiber infrastructure.
XGS-PON uses different wavelengths (1577 nm downstream, 1270 nm upstream) to coexist with GPON on the same ODN using wavelength division multiplexing (WDM).
Why TRUE?
XGS-PON supports higher bandwidth and more users while maintaining compatibility with the existing GPON ODN architecture.
Thus, the correct answer is A.

1490

850

1310

1550

* GPON Wavelengths :
* GPON networks use specific wavelengths for upstream and downstream transmission:
* Downstream (OLT to ONU) : 1490 nm.
* Upstream (ONU to OLT) : 1310 nm.
* Optional CATV overlay : 1550 nm (used for video services).
* Why 1490 nm?
* The ITU-T G.984.x standards specify 1490 nm as the wavelength for downstream data transmission in GPON networks. This wavelength is chosen for optimal performance in fiber- optic communication.
* Other Options :
* 850 nm : Used in multimode fiber for short-distance communication, not in GPON.
* 1310 nm : Used for upstream transmission in GPON.
* 1550 nm : Optional wavelength for CATV overlay, not for standard downstream data.
Thus, the correct answer is A .

When other SNMP parameters are correctly configured, how to configure the Trap source address of a device to ensure that the NMS can receive device alarms normally?

Set the trap source address to 127.0.0.1.

Set the trap source address to the loopback address.

Set the trap source address to the address used by the NMS to add the device.

Alle oben genannten Punkte

* SNMP Trap Source Address :
* The trap source address is the IP address used by the device to send SNMP traps to the NMS (Network Management System).
* Configuration Options :
* Option A : Setting the trap source address to 127.0.0.1 (localhost) is incorrect because it is not routable and cannot be used for communication with the NMS.
* Option B : Using the loopback address is possible but not recommended unless the NMS is explicitly configured to accept traps from the loopback address.
* Option C : Setting the trap source address to the same address used by the NMS to add the device ensures proper communication and alignment between the device and NMS.
* Option D : Incorrect because not all options are valid.
* Why C?
* Configuring the trap source address to match the address used by the NMS ensures that the NMS can correctly identify and process traps from the device.
Thus, the correct answer is C .

The Ethernet II packet header (without the VLAN tag) contains ( ) bytes?

The Ethernet II frame is the most commonly used Ethernet frame format. It consists of several fields, and its structure is well-defined in networking standards.
Structure of the Ethernet II Header:
Destination MAC Address (6 bytes): Specifies the MAC address of the intended recipient.
Source MAC Address (6 bytes): Specifies the MAC address of the sender.
EtherType (2 bytes): Indicates the protocol encapsulated in the payload (e.g., IPv4, ARP).
Total Size:
The Ethernet II header without a VLAN tag is 14 bytes in size. If a VLAN tag is added (using IEEE
802.1Q), the header size increases to 18 bytes due to the additional 4-byte VLAN tag.

NEW QUESTION 224

NEW QUESTION 228
GPON is an Ethernet-based passive optical access technology that complies with IEEE 802.3ah.

WAHR

FALSCH

GPON Overview:
GPON (Gigabit Passive Optical Network) is a fiber-optic access technology standardized by the ITU-T (International Telecommunication Union) under the G.984.x series of standards. It is not based on Ethernet but uses its own framing structure called GEM (GPON Encapsulation Method) for data transmission.
IEEE 802.3ah:
IEEE 802.3ah is the standard for EPON (Ethernet Passive Optical Network) , which is a competing technology to GPON.
EPON uses Ethernet frames for data transmission and is standardized by the IEEE, unlike GPON, which is standardized by ITU-T.
Why FALSE?
The statement incorrectly associates GPON with IEEE 802.3ah, which applies to EPON, not GPON.
Thus, the correct answer is B.
