PSICOFXP está de cumpleaños (5), FELICIDADES!!!
Les indico que la curricula ya cambio de la Versión 3.1 a la 3.1.1, por lo que creo que los examenes también cambiarán.
Aqui les traigo el examen Final del CCNA 1, versión 3.1.1. Por supuesto está en formato texto sin los dibujos.
1
Refer to the exhibit. A newly hired technician has a task of terminating CAT 5 UTP cables. The network administrator visually examined the cables the technician terminated. Some of the cables have connectors as shown in the exhibit. What should the network administrator explain to the technician about the cables?
Both cables are acceptable.
The cable in Graphic A will produce more crosstalk.
The cable in Graphic A should be used in the more critical network segments.
The cable in Graphic A is preferred because it will be easier to crimp the connector.
2 In the exhibit, the connections between the devices are labeled A, B, C, D, and E. For each connection, what is the correct UTP cable to use?
A=straight, B=rollover, C=straight, D=crossover, E=crossover
A=rollover, B=crossover, C=crossover, D=straight, E=straight
A=rollover, B=straight, C=straight, D=crossover, E=straight
A=rollover, B=straight, C=straight, D=crossover, E=crossover
A=straight, B=crossover, C=rollover, D=straight, E=straight
3 How many collision domains are shown in the diagram?
three
four
five
six
seven
eight
4 Refer to the exhibit. A network administrator has configured a network after subnetting the network number 192.168.0.0/28. Workstation 1 is not able to communicate with Workstation 2. What is the cause of this loss in communications?
Workstation 1 and Workstation 2 are on the same subnet.
The serial connections are using addresses from the LAN subnets.
Workstation 1 is not on the same network that the Router 1 LAN interface is on.
If routers are used in the network, IP addresses do not need to be subnetted.
5 Why do vendors utilize the OSI model when designing networking products?
It places requirements on all vendors that develop proprietary networking technologies for advance networking systems.
It ensures greater compatibility and interoperability with equipment from different vendors.
The International Organization for Standards develops all new products to be incorporated into the product.
It is mandated by the International Organization for Standardization that network products be compliant with the OSI model.
6 How does a switch learn the addresses of hosts connected to its ports?
All source MAC addresses must be manually configured in CAM.
The switch reads the source MAC address on incoming frames and records it in CAM.
**The switch reads the destination MAC address on incoming frames and records it in CAM.
If a switch port is full duplex, the switch reads both the source and destination MAC addresses on incoming frames and records them in CAM.
7 Which devices will create multiple collision domains in an Ethernet network? (Choose two.)
NIC
hub
switch
router
repeater
8 Refer to the exhibit. Which diagram represents the network topology that an administrator would prefer, and why would the administrator prefer it?

Diagram B. It extends the collision domain.
Diagram B. It prevents the frames from looping.
Either network will perform equally well.
9 Consider the networks shown in the exhibit. Host A is sending packets to host B. Which layer of the OSI model is being used when the router is making the calculated decision to determine which interface to send the packet out?

A switch manages frames faster than a hub does.
A switch operates at 100 Mbps. A hub operates at a maximum of 10 Mbps.
A switch modifies the Ethernet frame to remove any errors. A hub forwards the frame exactly as it arrived.
A switch provides more bandwidth by sending frames only out the port to which the destination device is attached. A hub sends the frame out all ports except the source port.
