New Cisco 200-125 Exam Dumps Collection (Question 1 - Question 10)

Question No: 1

What is the alternative notation for the IPv6 address B514:82C3:0000:0000:0029:EC7A:0000:EC72?

A. B514 : 82C3 : 0029 : EC7A : EC72

B. B514 : 82C3 :: 0029 : EC7A : EC72

C. B514 : 82C3 : 0029 :: EC7A : 0000 : EC72

D. B514 : 82C3 :: 0029 : EC7A : 0 : EC72

Answer: D

Explanation:

There are two ways that an IPv6 address can be additionally compressed: compressing leading zeros and substituting a group of consecutive zeros with a single double colon (::). Both of these can be used in any number of combinations to notate the same address. It is important to note that the double colon (::) can only be used once within a single IPv6 address notation. So, the extra 0u2019s can only be compressed once.


Question No: 2

Which parameter would you tune to affect the selection of a static route as a backup, when a dynamic protocol is also being used?

A. hop count

B. administrative distance

C. link bandwidth

D. link delay

E. link cost

Answer: B

Explanation:

By default the administrative distance of a static route is 1, meaning it will be preferred over all dynamic routing protocols. If you want to have the dynamic routing protocol used and have the static route be used only as a backup, you need to increase the AD of the static route so that it is higher than the dynamic routing protocol.


Question No: 3

Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.)

Router(config)# router ospf 1

A. All OSPF routers in an area must have the same process ID.

B. Only one process number can be used on the same router.

C. Different process identifiers can be used to run multiple OSPF processes

D. The process number can be any number from 1 to 65,535.

E. Hello packets are sent to each neighbor to determine the processor identifier.

Answer: C,D

Explanation:

Multiple OSPF processes can be configured on a router using multiple process IDu2019s. The valid process IDu2019s are shown below:

Edge-B(config)#router ospf ?

<1-65535> Process ID


Question No: 4

Refer to the exhibit.

Why is flash memory erased prior to upgrading the IOS image from the TFTP server?

A. The router cannot verify that the Cisco IOS image currently in flash is valid.

B. Flash memory on Cisco routers can contain only a single IOS image.

C. Erasing current flash content is requested during the copy dialog.

D. In order for the router to use the new image as the default, it must be the only IOS image in flash.

Answer: C

Explanation:

During the copy process, the router asked u201cErasing flash before copying? [confirm]u201d and the administrator confirmed (by pressing Enter) so the flash was deleted.

Note: In this case, the flash has enough space to copy a new IOS without deleting the current one. The current IOS is deleted just because the administrator wants to do so. If the flash does not have enough space you will see an error message like this:

%Error copying tftp://192.168.2.167/ c1600-k8sy-mz.l23-16a.bin (Not enough space on device)


Question No: 5

Which two of these statements regarding RSTP are correct? (Choose two.)

A. RSTP cannot operate with PVST+.

B. RSTP defines new port roles.

C. RSTP defines no new port states.

D. RSTP is a proprietary implementation of IEEE 802.1D STP.

E. RSTP is compatible with the original IEEE 802.1D STP.

Answer: B,E

Explanation:

When network topology changes, rapid spanning tree protocol (IEEE802.1W, referred to as RSTP) will speed up significantly the speed to re-calculate spanning tree. RSTP not only defines the role of other ports: alternative port and backup port, but also defines status of 3 ports: discarding status, learning status, forwarding status.

RSTP is 802.1D standard evolution, not revolution. It retains most of the parameters, and makes no changes.


Question No: 6

What is the result of issuing the frame-relay map ip 192.168.1.2 202 broadcast command?

A. defines the destination IP address that is used in all broadcast packets on DCLI 202

B. defines the source IP address that is used in all broadcast packets on DCLI 202

C. defines the DLCI on which packets from the 192.168.1.2 IP address are received

D. defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address

Answer: D

Explanation:

This command identifies the DLCI that should be used for all packets destined to the 192.168.1.2 address. In this case, DLCI 202 should be used.


Question No: 7

Refer to the exhibit.

What is the meaning of the term dynamic as displayed in the output of the show frame- relay map command shown?

A. The Serial0/0 interface is passing traffic.

B. The DLCI 100 was dynamically allocated by the router.

C. The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server.

D. The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud.

E. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned

through Inverse ARP.

Answer: E

Explanation:

Inverse Address Resolution Protocol (Inverse ARP) was developed to provide a mechanism for dynamic DLCI to Layer 3 address maps. Inverse ARP works much the same way Address Resolution Protocol (ARP) works on a LAN. However, with ARP, the device knows the Layer 3 IP address and needs to know the remote data link MAC address. With Inverse ARP, the router knows the Layer 2 address which is the DLCI, but needs to know the remote Layer 3 IP address.

When using dynamic address mapping, Inverse ARP requests a next-hop protocol address for each active PVC. Once the requesting router receives an Inverse ARP response, it updates its DLCI-to-Layer 3 address mapping table. Dynamic address mapping is enabled by default for all protocols enabled on a physical interface. If the Frame Relay environment supports LMI autosensing and Inverse ARP, dynamic address mapping takes place automatically. Therefore, no static address mapping is required.


Question No: 8

Based on the network shown in the graphic

Which option contains both the potential networking problem and the protocol or setting that should be used to prevent the problem?

A. routing loops, hold down timers

B. switching loops, split horizon

C. routing loops, split horizon

D. switching loops, VTP

E. routing loops, STP

F. switching loops, STP

Answer: F

Explanation:

The Spanning-Tree Protocol (STP) prevents loops from being formed when switches or bridges are interconnected via multiple paths. Spanning-Tree Protocol implements the 802.1D IEEE algorithm by exchanging BPDU messages with other switches to detect loops, and then removes the loop by shutting down selected bridge interfaces. This algorithm guarantees that there is one and only one active path between two network devices.


Question No: 9

The network administrator is asked to configure 113 point-to-point links. Which IP addressing scheme defines the address range and subnet mask that meet the requirement and waste the fewest subnet and host addresses?

A. 10.10.0.0/16 subnetted with mask 255.255.255.252

B. 10.10.0.0/18 subnetted with mask 255.255.255.252

C. 10.10.1.0/24 subnetted with mask 255.255.255.252

D. 10.10.0.0/23 subnetted with mask 255.255.255.252

E. 10.10.1.0/25 subnetted with mask 255.255.255.252

Answer: D

Explanation:

We need 113 point-to-point links which equal to 113 sub-networks < 128 so we need to borrow 7 bits (because 2^7 = 128).

The network used for point-to-point connection should be /30. So our initial network should be 30 u2013 7 = 23.

So 10.10.0.0/23 is the correct answer.

You can understand it more clearly when writing it in binary form:

/23 = 1111 1111.1111 1110.0000 0000

/30 = 1111 1111.1111 1111.1111 1100 (borrow 7 bits)


Question No: 10

Which statement is correct regarding the operation of DHCP?

A. A DHCP client uses a ping to detect address conflicts.

B. A DHCP server uses a gratuitous ARP to detect DHCP clients.

C. A DHCP client uses a gratuitous ARP to detect a DHCP server.

D. If an address conflict is detected, the address is removed from the pool and an administrator must resolve the conflict.

E. If an address conflict is detected, the address is removed from the pool for an amount of time configurable by the administrator.

F. If an address conflict is detected, the address is removed from the pool and will not be reused until the server is rebooted.

Answer: D

Explanation:

An address conflict occurs when two hosts use the same IP address. During address assignment, DHCP checks for conflicts using ping and gratuitous ARP. If a conflict is detected, the address is removed from the pool. The address will not be assigned until the administrator resolves the conflict.
