Directed
NEW QUESTION # 77
Which of the following descriptions about optical layer scheduling is wrong?
- A. Directioned means that the wavelength up and down from the local can only be transmitted to a certain fixed direction.
- B. Colorless means that any wavelength can go up and down through any port on the ROADM board, and the wavelength can be flexibly adjusted during service rerouting on the ASON network, thereby avoiding wavelength conflicts.

NEW QUESTION # 78
Which of the following statements about the delay test is wrong?
- A. During the delay test, the frame rate can be greater than the throughput
- B. The delay is divided into the delay of the store-and-forward device and the delay of the bit-forward device. Huawei devices are all store-and-forward devices
- C. The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device
- D. The timing starts from the entry of the first bit of the data frame, and ends when the first bit of the data frame appears on the output terminal P. The time difference between the two is the delay of the bit forwarding device
Answer: A
NEW QUESTION # 79
Which of the following statements about user side interfaces and network-side interfaces of E-Line services are true?
- A. User-side interfaces are NNIs, and network-side interfaces are UNIs.
- B. User-side interfaces are UNIs, and network-side interfaces are NNIs.
- C. User-side interfaces are Layer 2 ports, and network-side interfaces are Layer 3 ports.
- D. User-side Interfaces are Layer 3 ports, and network side Interfaces are Layer 7 ports.
Answer: B,C
Explanation:
In E-Line services, user-side interfaces are typically UNIs (User Network Interfaces), and network-side interfaces are NNIs (Network-to-Network Interfaces). Also, user-side interfaces are generally Layer 2 ports, whereas network-side interfaces are Layer 3 ports. This distinction facilitates proper service access and network integration. The user side provides services to clients, while the network side connects different network segments or devices. This layering and interface classification are essential concepts in HCIP- Transmission for service provisioning and network architecture design.
NEW QUESTION # 80
Generally, which of the following operations will interrupt services on live networks?
- A. Warm reset on a service board
- B. Software loopback
- C. Hardware loopback
- D. Cold reset on a service board
Answer: B,C,D
Explanation:
Operations that generally interrupt services on live networks include (A) cold reset on a service board, (C) hardware loopback, and (D) software loopback. Cold reset reinitializes hardware and can disrupt traffic; hardware loopback physically loops the signal causing interruption; software loopback also reroutes signals internally, impacting live data flow. Warm reset, however, is designed to minimize or avoid service interruptions by restarting software processes without full hardware reinitialization. HCIP-Transmission emphasizes understanding these operational impacts for network maintenance planning to minimize service downtime.
