DsmbISP Chapter 3 - CCNA Discovery: Working at a Small-to-Medium Business or ISP - Version 4.1 2013

1	What are two advantages of having ISP-managed services? (Choose two.) do not require leasing costs for the services predictable billing eliminate the need for data backup increase availability of help desk services do not require a Service Level Agreement

2	Which three issues should be noted on the technician's site survey report? (Choose three.) unlabeled cables only two power outlets per wall in each room poor physical security of network devices horizontal cabling runs under 100 meters lack of UPS for critical devices two users sharing the same computer

3	What three things are included in a logical topology document? (Choose three.) the location of cables, computers, and other peripherals the path that the data takes through a network the wireless signal coverage area the wiring closet and access point locations the device names and Layer 3 addressing information the location of routing, network address translation, and firewall filtering

4	Which device has the ability to break up broadcast and collision domains? repeater hub router switch

5	What does the use of redundant network components supply to a network? scalability manageability compatibility reliability

6	What is the term for the location at the customer premise where the customer network physically connects to the Internet through a telecommunications service provider? backbone area point of presence network distribution facility intermediate distribution frame

7

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.

8	Refer to the exhibit. Which type of twisted pair cable is used between each device? A=console, B=straight, C=crossover, D= crossover, E=straight A=straight, B=straight, C=straight, D=crossover, E=console A=crossover, B=straight, C=straight, D=crossover, E=crossover A=console, B=straight, C=straight, D=crossover, E=crossover A=console, B=crossover, C=crossover, D=straight, E=straight

9	What must be added when a network expands beyond the coverage area of the current telecommunications room? MDF POP IDF IXP

10	Which three items are typically found in an MDF? (Choose three.) user workstations switches and routers fax machines network equipment racks the point of presence copier

11

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 review the new network design and discuss possible equipment upgrades and replacements

12	Refer to the exhibit. To allow IP communication between the two networks, what type of device is required? hub router switch access point

13	Which two benefits can be gained by locating network equipment in a telecommunications closet, rather than in a user area? (Choose two.) faster communication speeds improved physical security more resistant to hacker attempts centralized cable management less electrical usage

14

In what two ways will entering into a managed service agreement with an ISP for a network upgrade affect the costs that are incurred by the customer? (Choose two.) Customer IT training costs will increase to enable operation of the new equipment. The cost of hardware repairs and support will become the responsibility of the customer. Network upgrade and maintenance costs will become predictable. Staffing costs will increase because the customer will need to hire additional IT staff to complete the upgrade. The company will not need to spend a large amount of money to purchase the equipment upfront.

15

When designing a network upgrade, which two tasks should the onsite technician perform? (Choose two.) configure the servers and routers prior to delivery upgrade the network operating system and all client operating systems investigate and document the physical layout of the premises  document the final design for approval by the customer perform a site survey to document the existing network structure

16

A network technician is assigned to perform a site visit to a customer location to determine the requirements for a network upgrade. In addition to the currently installed equipment inventory, what other information about the hosts and networking devices should the technician obtain from the customer? the cost of the currently installed equipment all product keys for site license software any planned growth anticipated in the near future the memory requirements for installed application software

17	Which type of cable has a solid copper core with several protective layers including PVC, braided wire shielding, and a plastic covering? STP UTP coaxial fiber optic

18	A client requires a networking device that is capable of expansion to accomodate growing network demands. What characteristic must this device have to meet this requirement? ability to monitor operation and change the settings for a device modular physical configuration ability to manage the device remotely ports that can be activated and deactivated

19

It is said that the goal for availability of a communications system is "five-9s". What is meant by this? A down time of .00001% is unacceptable. A network needs to be available 99.999% of the time. Five percent of all network expense covers 99% of user requirements. The most critical time for network availability is from 9:00 to 5:00 p.m. five days a week. The best time to do maintenance on a network is from 5:00 p.m. to 9:00 a.m. five days a week.

20

A manufacturing company is in the process of a network upgrade. Which two procedures describe the selection and design phase components of the upgrade process? (Choose two.) Bring the network into service. Create and test prototypes. Monitor the operation and record changes. Identify and address the weaknesses of the design. Compare the user experience with the goals in the documentation.
