Network Fundamentals 3

What is the default consequence for a network packet that does not match any specific 'permit' or 'deny' rule in an Access Control List?. The packet is forwarded to the destination. the packet is sent back to the source with an error message. the packet is discarded. the router holds the packet waiting for the admin intervention.

A network administrator needs to create a rule that denies FTP traffic from a specific subnet to a financial server, while allowing all other traffic from that subnet. Which type of ACL is required for this task?. Standard ACL. Extended ACL.

What is the primary security advantage of using SSH over Telnet for remote device management?. SSH uses more reliable port number by default. Telnet Software is harder to find and install. SSH session automatically close after a shorter period of inactivity. SSH transfer data, including credentials in an encrypted, more secure format.

A switch port is configured with port security. If the violation mode is set to 'protect', what action does the switch take when it detects traffic from an unauthorized MAC address?. it allows the traffic but logs violation and send an alert. it disables the port and send an alert. it drops the packets from the unauthorized MAC address but does not generate an alert.

In an ACL statement, the wildcard mask is the inverse of a subnet mask. What does the wildcard mask `0.0.0.31` represent when used with an IP address?. it matched only the single host provided. it matches the first 31 addresses in a subnet. it matches a range of 32 IP addresses.

Which HTTP method is specifically designed to submit data to a server to create a new resource, such as posting a comment on a blog?. POST. GET. PUT. DELETE.

Which port security MAC address learning mode dynamically learns MAC addresses and saves them to the running configuration, ensuring they are retained after a switch reboot?. Static MAC Address. Dynamic MAC Address. Sticky MAC Address.

An administrator creates a numbered ACL and later realizes a rule in the middle is incorrect. What is the primary limitation they face when trying to edit this specific rule?. only one numbered ACL can be active on a router at a time. changes to a numbered ACL require the router to be rebooted. the entire ACL must be deleted and recreated to change a single rule.

What is the fundamental difference in how data is transmitted by HTTPS compared to HTTP?. HTTPS transmits data in an encrypted format, while HTTP sends in a plain text format. HTTPS can only transfer text file while HTTP handle multimedia. HTTPS uses a different set of request methods than HTTP.

When an ACL is applied to a router's interface as an 'inbound-filter', at what point in the packet processing is the traffic evaluated?. after the packet has been routed and queued for the exit inteface. before the router performs a routing lookup to determine the exit inteface. as the packet is being transmitted out of the exit inteface.
