  B. An ARP request is broadcast at Layer 3.
  C. An ARP response is broadcast at Layer 2.
  D. ARP tables are maintained on Layer 3 devices.
  E. The destination MAC address of an ARP request is that of the ARP responder.
  F. ARP requests are broadcast at Layer 2.
  G. ARP resolves MAC addresses to NET addresses.
  H. ARP uses 0x0806 as the Type field in an Ethernet frame.
  D. ARP tables are maintained on Layer 3 devices.
  F. ARP requests are broadcast at Layer 2.

• Question 206:

  Refer to the exhibit.

  

  R1 and R2 are running RIPv1 for the 10.0.0.0 and 192.168.1.0 networks. No default or static routes have been configured on the routers. Which two statements about this topology are true? (Choose two.)

  A. R1 summarizes the 10.1.1.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R2. R2 summarizes the 10.2.2.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R1.
  B. To support this topology, R1 and R2 must be configured so that RIPv1 auto-summary is disabled.
  C. R1 sends information about the 10.1.1.0/24 subnet when it sends its RIPv1 routing updates to R2. R2 sends information about the 10.2.2.0/24 subnet when it sends its RIPv1 routing updates to R1. Example of RIPv1 update from R1 to R2:RIP: build update entriesnetwork 10.1.1.0/24 metric 1
  D. Hosts on the 10.1.1.0/24 subnet are unable to communicate with hosts on the 10.2.2.0/24 subnet.
  E. R1 accepts the 10.2.2.0/24 RIPv1 routing updates from R2 and installs the 10.2.2.0/24 route in its routing table. R2 accepts the 10.1.1.0/24 RIPv1 routing updates from R1 and installs the 10.1.1.0/24 route in its routing table.
  A. R1 summarizes the 10.1.1.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R2. R2 summarizes the 10.2.2.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R1.
  D. Hosts on the 10.1.1.0/24 subnet are unable to communicate with hosts on the 10.2.2.0/24 subnet.
