New Cisco 200-125 Exam Dumps Collection (Question 16 - Question 24)
New Questions 16
Which protocol supports sharing the VLAN configuration between two or more switches?
u201cVTP allows a network manager to configure a switch so that it will propagate VLAN configurations to other switches in the networku201d
VTP minimizes misconfigurations and configuration inconsistencies that can cause problems, such as duplicate VLAN names or incorrect VLAN-type specifications. VTP helps you simplify management of the VLAN database across multiple switches.
VTP is a Cisco-proprietary protocol and is available on most of the Cisco switches.
New Questions 17
Which component of the routing table ranks routing protocols according to their preferences?
A. administrative distance
B. next hop
D. routing protocol code
Administrative distance- This is the measure of trustworthiness of the source of the route.
If a router learns about a destination from more than one routing protocol, administrative distance is compared and the preference is given to the routes with lower administrative distance. In other words, it is the believability of the source of the route.
New Questions 18
Which command can you enter to display the hits counter for NAT traffic?
A. show ip nat statistics
B. debug ip nat
C. show ip debug nat
D. clear ip nat statistics
New Questions 19
Which component of a routing table entry represents the subnet mask?
A. routing protocol code
D. network mask
IP Routing Table Entry Types
An entry in the IP routing table contains the following information in the order presented: Network ID.The network ID or destination corresponding to the route. The network ID can be class-based, subnet, or supernet network ID, or an IP address for a host route. Network Mask.The mask that is used to match a destination IP address to the network ID. Next Hop.The IP address of the next hop.
Interface.An indication of which network interface is used to forward the IP packet. Metric.A number used to indicate the cost of the route so the best route among possible multiple routes to the same destination can be selected. A common use of the metric is to indicate the number of hops (routers crossed) to the network ID.
Routing table entries can be used to store the following types of routes:
Directly Attached Network IDs.Routes for network IDs that are directly attached. For directly attached networks, the Next Hop field can be blank or contain the IP address of the interface on that network.
Remote Network IDs.Routes for network IDs that are not directly attached but are available across other routers. For remote networks, the Next Hop field is the IP address of a local router in between the forwarding node and the remote network.
Host Routes.A route to a specific IP address. Host routes allow routing to occur on a per-
IP address basis. For host routes, the network ID is the IP address of the specified host and the network mask is 255.255.255.255.
Default Route.The default route is designed to be used when a more specific network ID or host route is not found. The default route network ID is 0.0.0.0 with the network mask of 0.0.0.0.
New Questions 20
If a router has four interfaces and each interface is connected to four switches, how many broadcast domains are present on the router?
New Questions 21
When enabled, which feature prevents routing protocols from sending hello messages on an interface'?
A. virtual links
C. directed neighbors
D. OSPF areas
You can use thepassive-interfacecommand in order to control the advertisement of routing information. The command enables the suppression of routing updates over some interfaces while it allows updates to be exchanged normally over other interfaces.
With most routing protocols, thepassive-interfacecommand restricts outgoing advertisements only. But, when used with Enhanced Interior Gateway Routing Protocol (EIGRP), the effect is slightly different. This document demonstrates that use of the passive-interfacecommand in EIGRP suppresses the exchange of hello packets between two routers, which results in the loss of their neighbor relationship. This stops not only routing updates from being advertised, but it also suppresses incoming routing updates. This document also discusses the configuration required in order to allow the suppression
of outgoing routing updates, while it also allows incoming routing updates to be learned normally from the neighbor.
New Questions 22
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
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.
New Questions 23
How can you disable DTP on a switch port?
A. Configure the switch port as a trunk.
B. Add an interface on the switch to a channel group.
C. Change the operational mode to static access.
D. Change the administrative mode to access.
New Questions 24
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
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.
