- Dthe memory requirements for installed application software
5Refer to the exhibit. What type of device is used to connect two networks?
- Ahub
- Brouter
- Cswitch
- Daccess point
6It is said that the goal for availability of a communications system is "five-9s". What is meant by this?
- AA down time of .00001% is unacceptable.
- BA network needs to be available 99.999% of the time.
- CFive percent of all network expense covers 99% of user requirements.
- DThe most critical time for network availability is from 9:00 to 5:00 p.m. five days a week.
- EThe best time to do maintenance on a network is from 5:00 p.m. to 9:00 a.m. five days a week.
7What three things are included in a logical topology document? (Choose three.)
- Athe location of cables, computers, and other peripherals
- Bthe path that the data takes through a network
- Cthe wireless signal coverage area
- Dthe wiring closet and access point locations
- Ethe device names and Layer 3 addressing information
- Fthe location of routing, network address translation, and firewall filtering
8Which device has the ability to break up broadcast and collision domains?
- Arepeater
- Bhub
- Crouter
- Dswitch
9Why is it important to review the results of an on-site survey report with the customer before beginning the network design?
- Ato inform the customer of how much time the upgrade will take
- Bto discuss the implementation schedule for the new equipment
- Cto verify that the report accurately describes the current network and any plans for expansion
- Dto layout the new network design and discuss possible equipment upgrades and replacements
10A client requires a networking device that is capable of expansion to suit growing network demands. What type of device will suit this requirement?
- Aa networking device with ports that can be activated and deactivated
- Ba networking device with a modular physical configuration
- Ca networking device with the ability to be turned off remotely
- Da networking device with a cost per port that is as high as possible
11What does the use of redundant network components supply to a network?
- Ascalability
- Bmanageability
- Ccompatibility
- Dreliability
12What is the benefit for a company to use an ISR router?
- AAn ISR provides the functionality of a switch, router, and firewall in one device.
- BISRs use a PC operating system for routing traffic, thus simplifying configuration and management.
- CAn ISR is immune to security attacks by hackers and so replaces all other network security measures.
- DISRs make routing decisions at OSI Layer 7, thus providing more intelligence to the network than do other routers.
13Which three items are typically found in an MDF? (Choose three.)
- Auser workstations
- Bswitches and routers
- Cfax machines
- Dnetwork equipment racks
- Ethe point of presence
- Fcopier
14What are two advantages of having ISP-managed services? (Choose two.)
- Adoes not require leasing costs for service
- Bcan guarantee up to 99.999% availability
- Celiminates the need for data backup
- Dincreases availability of help desk services
- Edoes not require a Service Level Agreement
15A manufacturing company is in the process of a network upgrade. Which two statements are true about the phases of the upgrade process? (Choose two.)
- APhase 1 is used to determine network requirements.
- BPhase 2 includes creating an analysis report.
- CPhase 3 is based on an implementation schedule that allows extra time for unexpected events.
- DPhase 4 is where prototypes are created and tested.
- EPhase 5 includes identifying and addressing any weaknesses in the design.
16When designing a network upgrade, which two tasks should the onsite technician perform? (Choose two.)
- Aconfigure the servers and routers prior to delivery
- Bupgrade the network operating system and all client operating systems
- Cinvestigate and document the physical layout of the premises
- Ddocument the final design for approval by the customer
- Eperform a site survey to document the existing network structure
17What is the term for the location at the customer premise where the customer network physically connects to the Internet through a telecommunications service provider?
- Abackbone area
- Bpoint of presence
- Cnetwork distribution facility
- Dintermediate distribution frame
18Refer to the exhibit. Which type of twisted pair cable is used between each device?
- AA=console, B=straight, C=crossover, D= crossover, E=straight
- BA=straight, B=straight, C=straight, D=crossover, E=console
- CA=console, B=crossover, C=crossover, D=straight, E=straight
- DA=crossover, B=straight, C=straight, D=crossover, E=crossover
- EA=console, B=straight, C=straight, D=crossover, E=crossover
19In 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.)
- ACustomer IT training costs will increase to enable operation of the new equipment.
- BThe cost of hardware repairs and support will become the responsibility of the customer.
- CNetwork upgrade and maintenance costs will become predictable.
- DStaffing costs will increase because the customer will need to hire additional IT staff to complete the upgrade.
