1. What is an outcome of connecting 2 or even more switches together?

The variety of broadcast domains is boosted.The size of the broadcast domain is raised.*The variety of collision domains is reduced.The dimension of the collision domajor is enhanced.

Explain:When 2 or even more switches are associated together, the size of the broadactors doprimary is enhanced and also so is the variety of collision domain names. The variety of broadcast domain names is boosted only as soon as routers are added.


2. Refer to the exhilittle. How many broadactors domains are there?

*

1234*

Explain:A rexternal is provided to path web traffic between different netfunctions. Broadactors website traffic is not allowed to cross the rexternal and also therefore will be consisted of within the corresponding subnets where it originated.


3. What are two reasons a network administrator might want to create subnets? (Choose 2.)

simplifies netjob-related designimproves network performance *less complicated to implement security policies*reduction in number of routers neededreduction in variety of switches needed

Explain:Two reasons for producing subnets include reduction of as a whole network-related web traffic and improvement of network-related performance. Subnets additionally permit an administrator to implement subnet-based protection policies. The number of routers or switches is not impacted. Subnets perform not simplify network style.


4. Refer to the exhibit. A firm offers the resolve block of 128.107.0.0/16 for its network. What subnet mask would carry out the maximum number of equal size subnets while giving enough hold addresses for each subnet in the exhibit?

16. A netjob-related administrator needs to monitor netjob-related website traffic to and also from servers in a file facility. Which attributes of an IP addressing plan need to be applied to these devices?

random static addresses to enhance securityaddresses from various subnets for redundancypredictable static IP addresses for less complicated identification*dynamic addresses to alleviate the probability of duplicate addresses

Explain:When security servers, a netoccupational administrator needs to have the ability to quickly identify them. Using a predictable static addressing plan for these gadgets makes them less complicated to recognize. Server protection, redundancy, and duplication of addresses are not functions of an IP addressing plan.


17. Which 2 factors generally make DHCP the desired strategy of assigning IP addresses to hosts on large networks? (Choose 2.)

It eliminates the majority of deal with configuration errors.*It ensures that addresses are only used to tools that need a long-term attend to.It promises that eextremely gadget that needs an address will gain one.It provides an resolve only to gadgets that are authorized to be associated to the network.It reduces the burden on network-related assistance staff.*

Explain:DHCP is mostly the wanted approach of assigning IP addresses to hosts on huge networks bereason it reduces the burden on network-related assistance staff and also practically eliminates entry errors. However before, DHCP itself does not discriminate in between authorized and also unauthorized devices and will assign configuration parameters to all requesting gadgets. DHCP servers are typically configured to assign addresses from a subnet array, so tright here is no guarantee that every gadget that needs an deal with will get one.


18. A DHCP server is used to assign IP addresses dynamically to the hosts on a netjob-related. The attend to pool is configured through 192.168.10.0/24. Tright here are 3 printers on this netjob-related that need to usage scheduled static IP addresses from the pool. How many type of IP addresses in the pool are left to be assigned to other hosts?

254251*252253

Explain:If the block of addresses alsituated to the pool is 192.168.10.0/24, tright here are 254 IP addresses to be assigned to hosts on the netjob-related. As tbelow are 3 printers which must have actually their addresses assigned statically, then tbelow are 251 IP addresses left for assignment.


19. Refer to the exhilittle bit. A firm is deploying an IPv6 addressing plan for its network-related. The agency architecture record indicates that the subnet percentage of the IPv6 addresses is used for the brand-new ordered netoccupational architecture, with the website subarea to represent multiple geographical sites of the firm, the sub-website area to reexisting multiple campsupplies at each site, and also the subnet area to indicate each netjob-related segment separated by routers. With such a plan, what is the maximum variety of subnets achieved per sub-site?

0416*256

Explain:Since only one hexadecimal character is supplied to reexisting the subnet, that one character deserve to recurrent 16 different worths 0 via F.


20. What is the presettle for the hold resolve 2001:DB8:BC15:A:12AB::1/64?

2001:DB8:BC152001:DB8:BC15:A*2001:DB8:BC15:A:12001:DB8:BC15:A:12

Explain:The network portion, or preresolve, of an IPv6 address is identified through the presolve length. A /64 presettle size indicates that the initially 64 bits of the IPv6 resolve is the netoccupational percent. Hence the prefix is 2001:DB8:BC15:A.


21. Consider the adhering to variety of addresses:

2001:0DB8:BC15:00A0:0000::2001:0DB8:BC15:00A1:0000::2001:0DB8:BC15:00A2:0000::…2001:0DB8:BC15:00AF:0000::The prefix-size for the range of addresses is /60
Explain:All the addresses have the component 2001:0DB8:BC15:00A in widespread. Each number or letter in the attend to represents 4 bits, so the prefix-length is /60.
