21
Q

Which network device can serve as a boundary to divide a Layer 2 broadcast domain?

  1. Ethernet bridge
  2. access point
  3. router
  4. Ethernet hub
A

Router

22
Q

A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in the ARP cache. How will the device obtain a destination MAC address?

  1. It will send an ARP request to the DNS server for the destination MAC address.
  2. It will send the frame and use the device MAC address as the destination.
  3. It will send an ARP request for the MAC address of the destination device.
  4. It will send the frame with a broadcast MAC address.
  5. It will send an ARP request for the MAC address of the default gateway.
A

It will send an ARP request for the MAC address of the default gateway.

23
Q

A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the Gigabit 0/1 interface. What will the router do next?

  1. look into the ARP cache to determine the destination IP address
  2. route the packet out the Gigabit 0/1 interface
  3. create a new Layer 2 Ethernet frame to be sent to the destination
  4. look into the routing table to determine if the destination network is in the routing table
A

create a new Layer 2 Ethernet frame to be sent to the destination

24
Q

When a new standard is proposed, each stage of the development and approval process is recorded in a numbered _________________-document so that the evolution of the standard is tracked.

A

Request for Comments (RFC) document

25
Q
