8. Which device has the ability to break up broadcast and collision domains?
• repeater
• hub
• router
• switch
Jawab:

• router
9. Why is it important to review the results of an on-site survey report with the customer before beginning the network design?
• to inform the customer of how much time the upgrade will take
• to discuss the implementation schedule for the new equipment
• to verify that the report accurately describes the current network and any plans for expansion
• to layout the new network design and discuss possible equipment upgrades and replacements
Jawab:

• to verify that the report accurately describes the current network and any plans for expansion

10. A client requires a networking device that is capable of expansion to suit growing network demands. What type of device will suit this requirement?
• a networking device with ports that can be activated and deactivated
• a networking device with a modular physical configuration
• a networking device with the ability to be turned off remotely

Jawab:
• a networking device with a modular physical configuration
11. What does the use of redundant network components supply to a network?
• scalability
• manageability
• compatibility
• reliability
Jawab:

• reliability
12. What is the benefit for a company to use an ISR router?
• An ISR provides the functionality of a switch, router, and firewall in one device.
• ISRs use a PC operating system for routing traffic, thus simplifying configuration and management.
• An ISR is immune to security attacks by hackers and so replaces all other network security measures.
• ISRs make routing decisions at OSI Layer 7, thus providing more intelligence to the network than do other routers.
Jawab:

• An ISR provides the functionality of a switch, router, and firewall in one device.
13. Which three items are typically found in an MDF? (Choose three.)
• user workstations
• switches and routers

• can guarantee up to 99.999% availability
• eliminates the need for data backup
• increases availability of help desk services
• does not require a Service Level Agreement
Jawab:

• can guarantee up to 99.999% availability

• increases availability of help desk services
15. A manufacturing company is in the process of a network upgrade. Which two statements are true about the phases of the upgrade process? (Choose two.)
• Phase 1 is used to determine network requirements.
• Phase 2 includes creating an analysis report.
• Phase 3 is based on an implementation schedule that allows extra time for unexpected events.
• Phase 4 is where prototypes are created and tested.
• Phase 5 includes identifying and addressing any weaknesses in the design.
Jawab:

• Phase 1 is used to determine network requirements.

• Phase 3 is based on an implementation schedule that allows extra time for unexpected events.
16. When designing a network upgrade, which two tasks should the onsite technician perform? (Choose two.)
