| Question ID 14647 | On which type of device is every port in the same collision domain?
|
| Option A | a router
|
| Option B | a Layer 2 switch
|
| Option C | a hub
|
| Correct Answer | C |
Explanation Explanation: Collision domainA collision domain is, as the name implies, a part of a network where packet collisions can occur. A collision occurs when two devices send a packet at the same time on the shared network segment. The packets collide and both devices must send the packets again, which reduces network efficiency. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.
| Question ID 14648 | Which statement about the inside interface configuration in a NAT deployment is true?
|
| Option A | It is defined globally
|
| Option B | It identifies the location of source addresses for outgoing packets to be translated using access or route maps.
|
| Option C | It must be configured if static NAT is used
|
| Option D | It identifies the public IP address that traffic will use to reach the internet.
|
| Correct Answer | B |
Explanation Explanation: This module describes how to configure Network Address Translation (NAT) for IP address conservation and how to configure inside and outside source addresses. This module also provides information about the benefits of configuring NAT for IP address conservation. NAT enables private IP internetworks that use nonregistered IP addresses to connect to the Internet. NAT operates on a device, usually connecting two networks, and translates the private (not globally unique) addresses in the internal network into legal addresses before packets are forwarded onto another network. NAT can be configured to advertise to the outside world only one address for the entire network. This ability provides additional security by effectively hiding the entire internal network behind that one address. NAT is also used at the enterprise edge to allow internal users access to the Internet and to allow Internet access to internal devices such as mail servers.
