True or False, TYPEWRITER is the longest dictionary word that can be typed using keys in only one row on your standard qwerty keyboard

• True

• False

True or False, he primary functions of a router are to determine the best path to forward packets based on the information in its routing table, and to forward packets toward their destination

• True

• False

The router uses its IP _______ table to determine which path (route) to use to forward a packet

True or False, the longest match is the route in the routing table that has the least number of far-left matching bits with the destination IP address of the packet. The longest match is always the preferred route

• True

• False

True or False, Directly Connected Networks are Networks that are not directly connected to the router

• True

• False

Select ALL the Packet Forwarding Decision Processes

• The data link frame with an encapsulated IP packet arrives on the ingress interface.

• The router examines the destination IP address in the packet header and consults its IP routing table

• The router finds the longest matching prefix in the routing table

• The router encapsulates the packet in a data link frame and forwards it out the egress interface. The destination could be a device connected to the network or a next-hop router

• However, if there is no matching route entry the packet is dropped.

True or False, to encapsulate the packet in the Ethernet frame, the router needs to determine the destination MAC address associated with the destination IP address of the packet

• True

• False

Routers support three packet forwarding mechanisms, select ALL three

• Cisco Express Forwarding (CEF)

• Process switching

• Slow switching

• Fast switching

True or False, Process switching is a new technology

• True

• False

True or False, Cisco Express Forwarding is the most recent and default Cisco IOS packet-forwarding mechanism

• True

• False
