The sensor communicates with a controller that automatically shuts down the line and activates an alarm. What type of communication does this scenario represent? The security policy in a company specifies that the staff in the sales department must use a VPN to connect to the corporate network to access the sales data when they travel to meet customers.
What component is needed by the sales staff to establish a remote VPN connection? They should be placed as close as possible to the source of the traffic to be denied. What is used to pre-populate the adjacency table on Cisco devices that use CEF to process packets? A network administrator is testing IPv6 connectivity to a web server.

CCNA 1 Practice Final Exam V4
Last Updated on April 2, by Admin. H1 creates the first Layer 2 header. The R1 router has to examine the destination IP address to determine how the packet is to be routed. If the packet is to be routed out another interface, as is the case with R1, the router strips the current Layer 2 header and attaches a new Layer 2 header. When R2 determines that the packet is to be sent out the LAN interface, R2 removes the Layer 2 header received from the serial link and attaches a new Ethernet header before transmitting the packet. Refer to the exhibit. Which highlighted value represents a specific destination network in the routing table?
