A. Before they are routed to an outbound interface.
B. After they are routed for outbound traffic.
C. After they are routed to an outbound interface while queuing.
D. Before and after they are routed to an outbound interface.

Câu hỏi này liên quan đến thứ tự xử lý các gói tin khi một router có áp đặt các accesslist. Khi router có một inbound accesslist, gói tin sẽ được xử lý bởi access list trước khi gói đó được router chuyển ra outbound interface.

Vậy trong câu hỏi này, chọn A 'Before they are routed to an outbound interface.'

Có vậy mà cũng hỏi ku, đại ca nè. Cú pháp câu lệnh để dùng IGRP routing protocol là:

Câu này mình nghĩ là C, D và E thì đúng hơn. Phải không mấy huynh trưởng?

QUESTION NO: 202
Study the Exhibit below carefully:

VTP Version: 2
Configuration Revision: 0
Maximum VLANs supported locally: 64
Number of existing VLANs: 5
VTP Operating Mode: Client

B. Create and change VLANs.
C. Passes information about VTP configuration.
D. VTP is disabled on this device.
E. VTP is not saved to NVRAM.

Còn câu này thì có lẻ do English của mình hơi bị bèo cho nên không hiểu phải chọn A hay là C hay là E, bởi thấy cái nào cũng đúng theo định nghĩa VTP client hết. Mong được các huynh trưởng bàn luận thêm.

Mình cũng có một câu này:
QUESTION NO: 57
To upgrade a network, emphasis must be placed on efficiency and error-free transport rather than fast transport. For this purpose, new switches had been purchased. Which switching mode should be configured on these new switches to have the desired effect?
A. 802.1q forwarding
B. VTP transparent mode
C. cut-through
D. store-and-forward
E. fragment-free
F. frame-filtering
Mình thì cho là Fragment-Free. Bởi cái này theo mình hiểu được thì nó kết hợp cả ưu điểm error-free của store and forward và ưu điểm của nhanh của cut-through --> efficiency. Còn bạn mình thì cho rằng là store and forward. Vậy còn các huynh trưởng thì sao?

câu này chọn store-and-forward là đúng nhất vì mode store&forward nhận toàn bộ frame và kiểm tra lỗi của frame bằng field FCS nên khi forward frame bị lỗi sẽ không forward, fragment-free chỉ kiểm tra tính là frame này không bị lỗi do collision mà thôi (nhận vào 64 byte mới bắt đầu forward)
