Chào các bạn
Mình sắp thi CCNA rồi. Mình đang test theo *******, mình cũng biết là ******* có nhiều đáp án sai. Mình post lên đây vài câu hỏi mong được sự ghóp ý của các bạn tìm cho mình đáp án đúng Xin cảm ơn các bạn nhiều lắm.
1.Study the Exhibit below carefully:
What is the function of the Frame Relay DLCI with regard to ********A?
*******A ---------------FR---------------*******B
A. Defines the signaling standard between ********A and ********B,
B. Identifies the type of encapsulation in operation between ********A and ********B.
C. Identifies the circuit between ********B and the frame switch.
D. Defines the signaling standard between ********A and the frame switch.
Answer: C
Câu này phải là Identifies the circuit between ********A and the frame switch chứ nhỉ , đáp án C ghi nhầm ah?
2. Documenting the name of the IOS image file of each router in the network is part of updating network documentation.
Which of the following commands can be used to obtain this information?
A. Router# show IOS
B. Router# show version
C. Router# show image
D. Router# show protocols
E. Router# show flash
Answer: B
3. You are a network technician at ********, Inc. The router topology for the ******** network is shown in the following exhibit:
Client *******A------E0-Router*******-E1--------------SW---server
********A is communicating with the server.
What will be the source MAC address of the frames that ********A receives from the server?
A. The MAC address of router interface e0.
B. The MAC address of router interface e1.
C. The MAC address of ********A.
D. The MAC address of the server network interface.
Answer: B
4. Which field of frame id used by error detection schemes when checking on errors?
A. MTU
B. PDU
C. FCS
D. Flag
E. MAC
F. BRI
Answer: D
5. Which of the following fields of frame is used by detection schemes to perform its function?
A. ERR
B. Flag
C. FCS
D. MTU
E. MAC
F. PDU
Answer: C
6. You are a network technician at ********, Inc. You have been assigned a junior trainee named Ellen. She wants you to describe what is specific for a global command.
What would your response be?
A. A command that is available in every release of IOS, regardless of the version or deployment status.
B. A command that is set once and will result in affecting the rest of the router operationability.
C. A command that is implemented in all IOS versions.
D. A command that is universal in application supporting different types of protocols.
E. A command that can be entered in any configuration mode.
Answer: A
7. Which of the following commands will configure an interface on a Catalyst 2900 series switch to carry traffic from all VLANs to another directly connected switch? (What would your response be?)
A. Switch(config-if)# vlan all
B. Switch(config-if)# switchport trunk encapsulation dot1q
C. Switch(config-if)# switchport access vlan all
D. Switch(config-if)# switchport mode trunk
E. Switch(config-if)# switchport access clan 30
Answer: C, D
8. Study the Exhibit below carefully:
You are the network administrator at ********. ********A is using multiple routing protocols according to the exhibit. Assuming that all networks that are connected are advertised, there are no redistribution of routes, and all other parameters are set to default, which path do you think will ********A use to reach ********D?
A. It will take the route via ********B.
B. It will take the route via ********C.
C. It will use the route with the highest metric.
D. It will load balance over both paths.
E. It will take the shortest route
Answer: A
Câu này mình không post được ảnh lên nhưng mình mô tả thế này : Có 4 router kết nối theo kiểu vòng tròn như sau TK B----TK A-----TK C ---TK D ----TK B , trong đó TK B dùng OSPF, TK C dùng IGRP , câu này hỏi đường đi từ Tk A đến TK D sẽ qua đường nào? Ở đây đáp án là A nhưng theo mình phải là B vì các thông số là default thì IGRP có metric nhỏ hơn OSPF.
9. Study the Exhibit below carefully:
London#show vtp status
VTP Version: 2
Configuration Revision: 0
Maximum VLANs supported locally: 64
Number of existing VLANs: 5
VTP Operating Mode: Client
VTP Domain Name: London
VTP Pruning Mode: Disabled
VTP V2 Mode: Disabled
VTP Traps Generation: Disabled
<br>Above is an illustration of the output of the London switch. What is the function of this switch?
A. Learn and saved VTP configuration in the running configuration.
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.
Answer: C
