New Cisco 200-125 Exam Dumps Collection (Question 12 - Question 21)

Question No: 12

Refer to the exhibit.

A new subnet with 60 hosts has been added to the network. Which subnet address should this network use to provide enough usable addresses while wasting the fewest addresses?

A. 192.168.1.56/26

B. 192.168.1.56/27

C. 192.168.1.64/26

D. 192.168.1.64/27

Answer: C

Explanation:

A subnet with 60 host is 2*2*2*2*2*2 = 64 -2 == 62

6 bits needed for hosts part. Therefore subnet bits are 2 bits (8-6) in fourth octet. 8bits+ 8bits+ 8bits + 2bits = /26

/26 bits subnet is 24bits + 11000000 = 24bits + 192 256 u2013 192 = 64

What are three benefits of GLBP? (Choose three.)

A. GLBP supports up to eight virtual forwarders per GLBP group.

B. GLBP supports clear text and MD5 password authentication between GLBP group members.

C. GLBP is an open source standardized protocol that can be used with multiple vendors.

D. GLBP supports up to 1024 virtual routers.

E. GLBP can load share traffic across a maximum of four routers.

F. GLBP elects two AVGs and two standby AVGs for redundancy.

Answer: B,D,E

Question No: 16

What two things will a router do when running a distance vector routing protocol? (Choose two.)

A. Send periodic updates regardless of topology changes.

B. Send entire routing table to all routers in the routing domain.

C. Use the shortest-path algorithm to the determine best path.

D. Update the routing table based on updates from their neighbors.

E. Maintain the topology of the entire network in its database.

Answer: A,D

Explanation:

Distance means how far and Vector means in which direction. Distance Vector routing protocols pass periodic copies of routing table to neighbor routers and accumulate distance vectors. In distance vector routing protocols, routers discover the best path to destination from each neighbor. The routing updates proceed step by step from router to router.

Question No: 17

Cisco Catalyst switches CAT1 and CAT2 have a connection between them using ports FA0/13. An 802.1Q trunk is configured between the two switches. On CAT1, VLAN 10 is chosen as native, but on CAT2 the native VLAN is not specified.

What will happen in this scenario?

A. 802.1Q giants frames could saturate the link.

B. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.

C. A native VLAN mismatch error message will appear.

D. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send tagged frames.

Answer: C

Explanation:

A u201cnative VLAN mismatchu201d error will appear by CDP if there is a native VLAN mismatch on an 802.1Q link. u201cVLAN mismatchu201d can cause traffic from one vlan to leak into another vlan.

Question No: 18

A router has two Fast Ethernet interfaces and needs to connect to four VLANs in the local network. How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance?

A. Use a hub to connect the four VLANS with a Fast Ethernet interface on the router.

B. Add a second router to handle the VLAN traffic.

C. Add two more Fast Ethernet interfaces.

D. Implement a router-on-a-stick configuration.

Answer: D

Explanation:

A router on a stick allows you to use sub-interfaces to create multiple logical networks on a single physical interface.

Question No: 19

What are three benefits of implementing VLANs? (Choose three.)

A. A higher level of network security can be reached by separating sensitive data traffic from other network traffic.

B. A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure.

C. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.

D. Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size.

E. Broadcast storms can be mitigated by decreasing the number of broadcast domains, thus increasing their size.

F. VLANs make it easier for IT staff to configure new logical groups, because the VLANs all belong to the same broadcast domain.

G. Port-based VLANs increase switch-port use efficiency, thanks to 802.1Q trunks.

Answer: A,C,D

Explanation:

Benefits of VLANs

VLAN is a network structure which allows users to communicate while in different locations by sharing one multicast domain and a single broadcast. They provide numerousnetworkingbenefits and have become popular in the market. For instance, it helps reduce administrative costs when users are geographically dispersed.

1. Inexpensive

The popularity of VLANs is due to the fact that changes, adds, and moves can be attained simply by making necessary configurations on the VLAN port. Time-consuming, re- addressing, and host reconfigurations is now a thing of the past, because network configuration can be made at ease when need arises.

2. Better management

A VLAN typically solve the scalability issues that exist in a large network by breaking the main domain into several VLAN groups or smaller broadcast configurations, thereby encourage better control of multicast traffic as well as broadcast domains.

3. Improves network security

High-security can be positioned in different VLAN groups to ensure that non-members

cannot receive their broadcasts. On the other hand, a router is added and workgroups relocated into centralized locations.

4. Enhances performance

A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.

5. Segment multiple networks

VLANs are typically used to achieve multiple purposes. They are popularly used to reduce broadcast traffic. Each VLAN creates a separate, smaller broadcast domain.

6. Better administration

VLANs facilitate grouping of multiple geographical stations. When VLAN users move to another physical location, the network does not have to be configured.

Question No: 20

Which subnet mask would be appropriate for a network address range to be subnetted for up to eight LANs, with each LAN containing 5 to 26 hosts?

A. 0.0.0.240

B. 255.255.255.252

C. 255.255.255.0

D. 255.255.255.224

E. 255.255.255.240

Answer: D

Explanation:

For a class C network, a mask of 255.255.255.224 will allow for up to 8 networks with 32 IP addresses each (30 usable).

Question No: 21

Which characteristics are representatives 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

Explanation:

Each of routers running link-state routing protocol learns paths to all the destinations in its u201careau201d so we can say although it is a bit unclear.

Link-state routing protocols generate routing updates only (not the whole routing table) when a change occurs in the network topology so

Link-state routing protocol like OSPF uses Dijkstra algorithm to calculate the shortest path -

>.

Unlike Distance vector routing protocol (which utilizes frequent periodic updates), link-state routing protocol utilizes event-triggered updates (only sends update when a change occurs)
