1. Which destination address is used in an ARP request frame?
- the physical address of the destination host
2. Which network device can serve as a boundary to divide a Layer 2 broadcast domain?
- Ethernet bridge
- access point
- Ethernet hub
3. Which term refers to the process of placing one message format inside another message format?
4. What is the purpose of the core layer in the Cisco hierarchical network design model?
- flow control between networks
- aggregation point for smaller networks
- high-speed backbone switching
- network access to end devices
5. Which network device has the primary function to send data to a specific destination based on the information found in the MAC address table?
6. Refer to the exhibit. How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?
- SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.
- SW1 drops the frame because it does not know the destination MAC address.
- SW1 floods the frame on all ports on the switch, excluding the interconnected port to switch SW2 and the port through which the frame entered the switch.
- SW1 forwards the frame directly to SW2. SW2 floods the frame to all ports connected to SW2, excluding the port through which the frame entered the switch.
7. What information does an Ethernet switch examine and use to build its address table?
- source MAC address
- source IP address
- destination MAC address
- destination IP address
8. Which three fields are found in an 802.3 Ethernet frame? (Choose three.)
- destination logical address
- media type identifier
- source physical address
- destination physical address
- frame check sequence
- source logical address
9. Which two devices would commonly be found at the access layer of the hierarchical enterprise LAN design model? (Choose two.)
- Layer 3 device
- modular switch
- access point
- Layer 2 switch
10. Which statement is true about broadcast and collision domains?
- Adding a router to a network will increase the size of the collision domain.
- The more interfaces a router has the larger the resulting broadcast domain.
- The size of the collision domain can be reduced by adding hubs to a network.
- Adding a switch to a network will increase the size of the broadcast domain.
11. How much data can be encapsulated into a normal sized Ethernet frame before it is sent over the network?
- 0 to 1024 bytes
- 64 to 1518 bytes
- 32 to 1500 bytes
- 46 to 1500 bytes
12. What is the purpose of ARP in an IPv4 network?
- to build the MAC address table in a switch from the information that is gathered
- to forward data onward based on the destination IP address
- to forward data onward based on the destination MAC address.
- to obtain a specific MAC address when an IP address is known
