CCNA 2 v6.0 (Routing & Switching Essentials v6) Chapter 4: Switched Networks: Check Your Understanding Questions Answers
1. What is a basic function of the Cisco Borderless Architecture distribution layer?
- Acting as a backbone
- Aggregating all the campus blocks
- Aggregating Layer 2 and Layer 3 routing boundaries
- Providing access to end-user devices
2. A network designer must provide a rationale to a customer for a design that will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice? (Choose two.)
- Easier to provide redundant links to ensure higher availability
- Less required equipment to provide the same performance levels
- Lower bandwidth requirements
- Reduced cost for equipment and user training
- Simpler deployment for additional switch equipment
3. What is a collapsed core in a network design?
- A combination of the functionality of the access and core layers
- A combination of the functionality of the access and distribution layers
- A combination of the functionality of the access, distribution, and core layers
- A combination of the functionality of the distribution and core layers
4. Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure? (Choose two.)
- User data traffic
- VoIP phone traffic
- Scanners and printers
- Mobile cell phone traffic
- Electrical system
5. What is a definition of a two-tier LAN network design?
- Access, distribution, and core layers collapsed into one tier, with a separate backbone layer
- Access and core layers collapsed into one tier, and the distribution layer on a separate tier
- Access and distribution layers collapsed into one tier, and the core layer on a separate tier
- Distribution and core layers collapsed into one tier, and the access layer on a separate tier
6. A local law firm is redesigning the company network so that all 20 employees can be connected to a LAN and to the Internet. The law firm would prefer a low-cost and easy solution for the project. What type of switch should be selected?
- Fixed configuration
- Modular configuration
- Stackable configuration
- StackPower
- StackWise
7. What are two advantages of modular switches over fixed-configuration switches? (Choose two.)
- Increased scalability
- Lower cost per switch
- Lower forwarding rates
- Need for fewer power outlets
8. What is one function of a Layer 2 switch?
- Determines which interface is used to forward a frame based on the destination MAC address
- Duplicates the electrical signal of each frame to every port
- Forwards data based on logical addressing
- Learns the port assigned to a host by examining the destination MAC address
9. What criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames?
- Destination IP address
- Destination MAC address
- Egress port
- Path cost
10. Which network device can be used to eliminate collisions on an Ethernet network?
- Firewall
- Hub
- Router
- Switch
11. Which type of address does a switch use to build the MAC address table?
- Destination IP address
- Destination MAC address
- Source IP address
- Source MAC address
12. What are two reasons a network administrator would segment a network with a Layer 2 switch? (Choose two.)
- To create fewer collision domains
- To create more broadcast domains
- To eliminate virtual circuits
- To enhance user bandwidth
- To isolate ARP request messages from the rest of the network
- To isolate traffic between segments
13. Which statement describes the microsegmentation feature of a LAN switch?
- All ports inside the switch form one collision domain.
- Each port forms a collision domain.
- Frame collisions are forwarded.
- The switch will not forward broadcast frames.
14. A __________________ network is one that uses the same infrastructure to carry voice, data, and video signals.
