- Question
What layer in the TCP/IP stack is equivalent to the Transport layer of the OSI model?
Options- A. Application
- B. Host-to-Host
- C. Internet
- D. Network Access
- Correct Answer
- Host-to-Host
ExplanationThe four layers of the TCP/IP stack (also called the DoD model) are Application/Process, Host-to-Host, Internet, and Network Access. The Host-to-Host layer is equivalent to the Transport layer of the OSI model. - 1. Which of the following commands will configure all the default VTY ports on a router?
Options- A. Router#line vty 0 4
- B. Router(config)#line vty 0 4
- C. Router(config-if)#line console 0
- D. Router(config)#line vty all Discuss
- 2. With which network type will OSPF establish router adjacencies but not perform the DR/BDR election process?
Options- A. Point-to-point
- B. Backbone area 0
- C. Broadcast multi-access
- D. Non-broadcast multi-access Discuss
- 3. You have 10 users plugged into a hub running 10Mbps half-duplex. There is a server connected to the switch running 10Mbps half-duplex as well. How much bandwidth does each host have to the server?
Options- A. 100 kbps
- B. 1 Mbps
- C. 2 Mbps
- D. 10 Mbps Discuss
- 4. Which layer 1 devices can be used to enlarge the area covered by a single LAN segment?
- Switch
- NIC
- Hub
- Repeater
- RJ45 transceiver
Options- A. 1 only

Options- A. Application
- B. Host-to-Host
- C. Internet
- D. Network Access Discuss
- 9. You have a Cisco mesh network. What protocol allows multiple APs to connect with many redundant connections between nodes?
Options- A. LWAPP
- B. AWPP
- C. STP
- D. IEEE Discuss
- 10. Where is a hub specified in the OSI model?
Options- A. Session layer

Correct Answer: Router(config)#line vty 0 4
Explanation:
From global configuration mode, use the
line vty 0 4 command to set all five default VTY lines.
Correct Answer: Point-to-point
Explanation:
No DR is assigned on any type of point-to-point link. No DR/BDR is assigned on the NBMA point-to-multipoint due to the hub/spoke topology. DR and BDR are elected on broadcast and non-broadcast multi-access networks. Frame Relay is a non-broadcast multi-access (NBMA) network by default.
Correct Answer: 10 Mbps
Explanation:
Each device has 10 Mbps to the server.
Correct Answer: 3 and 4
Explanation:
Not that you really want to enlarge a single collision domain, but a hub (multiport repeater) will provide this for you.
Correct Answer: Every 2 seconds
Explanation:
Every 2 seconds, BPDUs are sent out from all active bridge ports by default.
Correct Answer: 3, 4 and 5
Explanation:
Ethernet and Token Ring are LAN technologies and cannot be configured on a serial interface. PPP, HDLC, and Frame Relay are layer 2 WAN technologies that are typically configured on a serial interface.
Correct Answer: Application
Explanation:
Both FTP and Telnet use TCP at the Transport layer; however, they both are Application layer protocols, so the Application layer is the best answer.
Correct Answer: Internet
Explanation:
The four layers of the DoD model are Application/Process, Host-to-Host, Internet, and Network Access. The Internet layer is equivalent to the Network layer of the OSI model.
Correct Answer: AWPP
Explanation:
Each AP in a mesh network runs the Adaptive Wireless Path Protocol (AWPP). This protocol allows RAPs to communicate with each other to determine the best path back to the wired network via the RAP.
Correct Answer: Physical layer
Explanation:
Hubs regenerate electrical signals, which are specified at the Physical layer.
