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.

* Statement A: 'The trace successfully reached the www.cisco.com server.' This is true as indicated by the 'Trace complete' message at the end, showing that the trace has reached its destination.

* Statement C: 'The IPv6 address associated with the www.cisco.com server is 2600:1408:c400:38d::b33.' This is true because the final hop in the trace, which is the destination, has this IPv6 address.

* Statement B: 'The trace failed after the fourth hop.' This is incorrect as the trace continues beyond the fourth hop, despite some intermediate timeouts.

* Statement D: 'The routers at hops 5 and 6 are offline.' This is not necessarily true. The routers might be configured to not respond to traceroute requests.

* Statement E: 'The device sending the trace has IPv6 address 2600:1408:c400:38d::b33.' This is incorrect; this address belongs to the destination server, not the sender.

When a Cisco switch is not accessible from the network, the recommended out-of-band method to access its running configuration is through the console port. Out-of-band management involves accessing the network device through a dedicated management channel that is not part of the data network. The console port provides direct access to the switch's Command Line Interface (CLI) without using the network, which is essential when the switch cannot be accessed remotely via the network12.

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.

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.
