You want to store files that will be accessible by every user on your network.
Which endpoint device do you need?
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.

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

Which wireless security option uses a pre-shared key to authenticate clients?
WPA2-Personal, also known as WPA2-PSK (Pre-Shared Key), is the wireless security option that uses a pre-shared key to authenticate clients. This method is designed for home and small office networks and doesn't require an authentication server. Instead, every user on the network uses the same key or passphrase to connect1.
* What is a Wi-Fi Protected Access Pre-Shared Key (WPA-PSK)?
* Exploring WPA-PSK and WiFi Security
=========================
* WPA2-Personal: This wireless security option uses a pre-shared key (PSK) for authentication. Each client that connects to the network must use this key to gain access. It is designed for home and small office networks where simplicity and ease of use are important.
* WPA2-Enterprise: Unlike WPA2-Personal, WPA2-Enterprise uses 802.1x authentication with an authentication server (such as RADIUS) and does not rely on a pre-shared key.
* 802.1x: This is a network access control protocol for LANs, particularly wireless LANs. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
* 802.1q: This is a networking standard that supports VLAN tagging on Ethernet networks and is not related to wireless security.

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

A user reports that a company website is not available. The help desk technician issues a tracert command to determine if the server hosting the website is reachable over the network. The output of the command is shown as follows:
What can you tell from the command output?
The tracert command output shows the path taken to reach the destination IP address, 192.168.1.10. The command output indicates:
* Hops 1 and 2 are successfully reached.
* Hop 3 times out, meaning the router at hop 3 did not respond to the tracert request. However, this does not necessarily indicate a problem with forwarding packets, as some routers may be configured to block or not respond to ICMP requests.
* Hops 4 and 5 are successfully reached, with hop 5 being the destination IP 192.168.1.10, indicating that the server is reachable.
Thus, the correct answer is C. The server with the address 192.168.1.10 is reachable over the network.
* Cisco Traceroute Command
* Understanding Traceroute
The tracert command output indicates that the server with the address 192.168.1.10 is reachable over the network. The asterisk (*) at hop 3 suggests that the probe sent to that hop did not return a response, which could be due to a variety of reasons such as a firewall blocking ICMP packets or the router at that hop being configured not to respond to ICMP requests. However, since the subsequent hops (4 and 5) are showing response times, it means that the packets are indeed getting through and the server is reachable12.
