Tra loi cho cau hoi 42: LLQ, CQ, PQ va WFQ

LLQ = Low Latency Queuing
CQ = Custom Queuing
PQ = Priority Queuing
WFQ = Weighted Fair Queuing

Câu 67 là E, 68 là A,C phải kô ?
Câu 42, tôi đọc trong tài liệu QoS thì ISO hỗ trợ Class Based WFQ. ******** trả lời LLQ, CQ & PQ thôi???

QUESTION NO: 8
Of the following routing functions, which has a unique purpose from the others?
A. Holddown.
B. Hot standby.
C. Count-to-infinity.
D. Poison reverse.
******** B, tôi nghĩ là A mới đúng.

QUESTION NO: 9
In a Frame Relay network, what issue occurs due to routing protocols using split horizon?
A. A full mesh topology is required, which requires a lot of configuration.
B. Routers report Frame Relay errors due to routing updates not being forwarded..
C. Connectivity between networks is limited in a partial-mesh.
D. No routing traffic is sent to peer routers.

*******: C, tôi nghĩ là D.

[ptran]

Hold Down, Count to Infinity va Poison Reverse deu la nhung cach de tranh routing loop. Cau tra loi A la trat lat roi :-). Tra loi D cho cau hoi so 9 cung trat lat luon :-). Split Horizon khong cho routes forwarded den nhung nhanh khac do do "Connectivity between networks is limited in a partial-mesh". Ban co the khong xu dung Split Horizon cho partial-mesh.

Ở đây câu hỏi mình hiểu là chức năng nào của routing cùng có trong các routing protocol.
Các function: Count to Infinity va Poison Reverse chỉ có trong distance vector routing protocol thôi. Chỉ có Holddown có trong nhiều routing protocol, kể cả distace vector & link-state. (khi show ip protocol sẽ thấy holddown timer). Vây nên tôi nghĩ là câu A.
Mặc khác câu này chỉ có 1 lựa chọn thôi mà.

[ptran]

Hot standby khong phai la mot chuc nang cua bat cu mot routing protocol nao. Do do cau tra loi dung la B. HSRP (Hot Stanby Routing Protocol) khong phai la mot routing protocol nhu la RIP, OSPF, BGP, IGRP, EIGRP...O day cau hoi khong phai chon lua giua Link State voi Distance Vector. Hold Down, Count to Infinity va Poison Reverse la ba chuc nang dung de chong routing loop. Do la dac diem chung cua ca ba. Hot Standby khong co chuc nang nay.

[cubithongminh]

Ừ, câu 9 chọn D là đúng nhất.

[cubithongminh]

Ý lộn, câu C.

QUESTION NO: 7
How would you define a fault tolerant device?
A. A backup path exists for every link between the client and the server.

C. A backup device exists for every device between the client and the server.
D. Devices in the network can be hot-swapped without interrupting the network operation.
E. The device provides redundant backup within the device for each of its key components.

Mình nghĩ chọn câu E. (** chọn câu A)
