Question No. 1

You want to store files that will be accessible by every user on your network.

Which endpoint device do you need?

Show Answer Hide Answer
Correct Answer: B

To store files that will be accessible by every user on a network, you would need a server. A server is a computer system that provides data to other computers. It can serve data to systems on a local network (LAN) or a wide network (WAN) over the internet. In this context, a file server would be set up to store and manage files, allowing users on the network to access them from their own devices1.


What is a Server?

Understanding Servers and Their Functions

A server is a computer designed to process requests and deliver data to other computers over a local network or the internet. In this case, to store files that will be accessible by every user on the network, a file server is the appropriate endpoint device. It provides a centralized location for storing and managing files, allowing users to access and share files easily.

A . Access point: Provides wireless connectivity to a network.

C . Hub: A basic networking device that connects multiple Ethernet devices together, making them act as a single network segment.

D . Switch: A networking device that connects devices on a computer network by using packet switching to forward data to the destination device.

Thus, the correct answer is B. Server.

Question No. 2

Which command will display all the current operational settings configured on a Cisco router?

Show Answer Hide Answer
Correct Answer: D

The show running-config command is used on a Cisco router to display the current operational settings that are actively configured in the router's RAM. This command outputs all the configurations that are currently being executed by the router, which includes interface configurations, routing protocols, access lists, and other settings. Unlike show startup-config, which shows the saved configuration that the router will use on the next reboot, show running-config reflects the live, current configuration in use.


show running-config: This command displays the current configuration running on the router. It includes all the operational settings and configurations applied to the router.

show protocols: This command shows the status of configured protocols on the router but not the entire configuration.

show startup-config: This command displays the configuration saved in NVRAM, which is used to initialize the router on startup, but not necessarily the current running configuration.

show version: This command provides information about the router's software version, hardware components, and uptime but does not display the running configuration.

Question No. 4

Which two pieces of information should you include when you initially create a support ticket? (Choose 2.)

Show Answer Hide Answer
Correct Answer: A, C

Statement A: 'A detailed description of the fault.' This is essential for support staff to understand the nature of the problem and begin troubleshooting effectively.

Statement C: 'A description of the conditions when the fault occurs.' This helps in reproducing the issue and identifying patterns that might indicate the cause of the fault.

Statement B: 'Details about the computers connected to the network.' While useful, this is not as immediately critical as understanding the fault itself and the conditions under which it occurs.

Statement D: 'The actions taken to resolve the fault.' This is important but typically follows the initial report.

Statement E: 'The description of the top-down fault-finding procedure.' This is more of a troubleshooting methodology than information typically included in an initial support ticket.

Question No. 5

A host is given the IP address 172.16.100.25 and the subnet mask 255.255.252.0.

What is the CIDR notation for this address?

Show Answer Hide Answer
Correct Answer: D

The CIDR (Classless Inter-Domain Routing) notation for the subnet mask 255.255.252.0 is /22. This notation indicates that the first 22 bits of the IP address are used for network identification, and the remaining bits are used for host addresses within the network1.

=========================

* Subnet Mask to CIDR Notation: The given subnet mask is 255.255.252.0. To convert this to CIDR notation:

* Convert the subnet mask to binary: 11111111.11111111.11111100.00000000

* Count the number of consecutive 1s in the binary form: There are 22 ones.

* Therefore, the CIDR notation is /22.
