Your app needs to store the following information. For each type of information, decide whether you would use an array or a variable to store it:(a) All the messages a user has sent(b) The highest score a user has ever reached on the app(c) A username and password to unlock the app

Answers

Answer:

Array: (a) All the messages a user has sent.

Variable: (b) The highest score a use has reached on the app. (c) A username and password to unlock the app.

Explanation:

An array generally has more than one value whereas a variable can only contain a single value at any particular point in time. In addition, a variable has a limit whereas an array does not have any maximum limit. Therefore, it can be concluded that option (a) will be stored as an array while options (b) and (c) will be stored as variables.

A network engineer is troubleshooting a small LAN network with one border router, GW01 that connects to the Internet Service Provider’s (ISP) network.

What do you suggest the network engineer do to rectify this issue? Assume the problem is only on the organization’s LAN side of the network. Provide as much information as possible including specific commands and all required parameters.

Answers

Answer:

Create a default route on the border router. Check the NAT configuration and network addresses.

Explanation:

The LAN or local area network is a network meant for a small geographic area, ranging from a small home office to office building.

For a LAN to be connected to the internet, it is subscribed to a ISP. The ISP provides the internet/ global WAN resources to the LAN. The border router or stub is configured with a gateway of last resort or default route to route packets to the WAN network and a Network address translation, NAT, is used for a large LAN.

The syntax for default route configuration on the border router is;

Router(config)# IP route 0.0.0.0 0.0.0.0 s0/0/1
