New Cisco 200-125 Exam Dumps Collection (Question 2 - Question 11)

Question No: 2

Which entity assigns IPv6 addresses to end users?

A. ICANN

B. APNIC

C. RIR

D. ISPs

Answer: C

Question No: 3

Which three characteristics are representative of a link-state routing protocol? (Choose three.)

A. provides common view of entire topology

B. exchanges routing tables with neighbors

C. calculates shortest path

D. utilizes event-triggered updates

E. utilizes frequent periodic updates

Answer: A,C,D

Question No: 4

Which two passwords must be supplied in order to connect by Telnet to a properly secured Cisco switch and make changes to the device configuration? (Choose two.)

A. tty password

B. enable secret password

C. vty password

D. aux password

E. console password

F. username password

Answer: B,C

Explanation:

Telnet presents a potential security risk, so Telnet uses vty for connecting a remote Cisco switch. For access security, the vty password and enable password must be configured.

Question No: 5

Which two statements about late collisions are true? (Choose two.)

A. They may indicate a duplex mismatch.

B. By definition, they occur after the 512th bit of the frame has been transmitted.

C. They indicate received frames that did not pass the FCS match.

D. They are frames that exceed 1518 bytes.

E. They occur when CRC errors and interference occur on the cable.

Answer: A,B

Question No: 6

Which Cisco platform can verify ACLs?

A. Cisco Prime Infrastructure

B. Cisco Wireless LAN Controller

C. Cisco APIC-EM

D. Cisco IOS-XE

Answer: B

Question No: 7

Which option describes a benefit of a point-to-point leased line?

A. full-mesh capability

B. flexibility of design

C. low cost

D. simplicity of configuration

Answer: D

Question No: 8

Which switching method duplicates the first six bytes of a frame before making a switching decision?

A. fragment-free switching

B. store and-forward switching

C. cut through switching

D. ASIC switching

Answer: C

Explanation: Cut and Through method has lowest latency. In this method Switch only read first six bytes from frame after the preamble. These six bytes are the destination address of frame. This is the fastest method of switching. This method also processes invalid frames. Only advantage of this method is speed.

Question No: 9

What is a difference between TACACS+ and RADIUS in AAA?

A. Only TACACS+ allows for separate authentication.

B. Only RADIUS encrypts the entire access-request packet.

C. Only RADIUS uses TCP.

D. Only TACACS+ couples authentication and authorization.

Answer: A

Explanation: Authentication and Authorization

RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization.

TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting. After a NAS authenticates on a Kerberos server, it requests authorization information from a TACACS+ server without having to re-authenticate. The NAS informs the TACACS+ server that it has successfully authenticated on a Kerberos server, and the server then provides authorization information.

During a session, if additional authorization checking is needed, the access server checks with a TACACS+ server to determine if the user is granted permission to use a particular command. This provides greater control over the commands that can be executed on the access server while decoupling from the authentication mechanism.

Question No: 10

Which path does a router choose when it receives a packet with multiple possible paths to the destination over different routing?

A. the path with the lowest administrative distance

B. the path with the lowest metric

C. the path with both the lowest administrative distance and the highest metric

D. the path with both the lowest administrative distance and lowest metric

Answer: A

Question No: 11
