DsmbISP Chapter 3 Exam Answers


Q.1 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


Q.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


Q.3 Which two types of cable are used for initial router configuration? (Choose two.)

 serial cable
 rollover cable
 straight-through cable
 crossover cable
 patch cable
 console cable


Q.4 In addition to the inventory sheet, what other information about the hosts and networking equipment should be documented by the on-site technician while performing the site survey?

 any obsolete office equipment being stored
 all product keys for site license software
 any planned growth anticipated in the near future
 the memory requirements for installed application software



Q.5 Refer to the exhibit. What type of device is used to connect two networks?

 hub
 router
 switch
 access point


Q.6 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.


Q.7 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


Q.8. Which device has the ability to break up broadcast and collision domains?

 repeater
 hub
 router
 switch


Q.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


Q.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
 a networking device with a cost per port that is as high as possible


Q.11 What does the use of redundant network components supply to a network?

 scalability
 manageability
 compatibility
 reliability


Q.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.


Q.13 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


Q.14 What are two advantages of having ISP-managed services? (Choose two.)

 does not require leasing costs for service
 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


Q.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.


Q.16 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


Q.17 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



Q.18 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


Q.19 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.


Q.20 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


Q.21 What must be added when a network expands beyond the coverage area of the current telecommunications room?

 MDF
 POP
 IDF
 IXP
