Access List Challenge ~ CCNP, CCSP and CCIE Security Version 4 Training Institute in India- Delhi

You have just been given a shiny, new router to configure. As part of the configuration, you are asked to configure an outbound access list which will only permit traffic through to specific destinations. Here are the requirements that you are given for your access-list:
Match (and permit) the following destinations using an access-list. Your access list should use the fewest number of lines, and should not overlap any other address space.
Anything within the 10.0.0.0/8 address space.
Anything within the 172.16.0.0/12 address space.
Anything within the 192.168.0.0/16 address space.
Anything within the 169.254.0.0/16 address space.
Be warned, it is estimated that a very high percentage of readers will NOT have the correct answer.

access-list 199 permit ip any object-group TEST

What just happened here? Can you really match those in a single line? The answer deals with object groups, which allow grouping of other items. The object group still needs to be configured, but the question just asked for a short access list.
You can enter in either /x notation for mask, or with subnet mask information, as shown in the following examples:

object-group network TEST
 10.0.0.0 /8
 172.16.0.0 /12
 192.168.0.0 /16
 169.254.0.0 /16

The router will convert syntax, and the following will be what remains in your config for the group:

object-group network TEST
 10.0.0.0 255.0.0.0
 172.16.0.0 255.240.0.0
 192.168.0.0 255.255.0.0
 169.254.0.0 255.255.0.0

You can also nest object groups. You could configure the individual groups as follows:

object-group network A
 10.0.0.0 /8
object-group network B
 172.16.0.0 /12
object-group network C
 192.168.0.0 /16 

object-group network RFC1918
 group-object A
 group-object B
 group-object C 

object-group network APIPA
 169.254.0.0 /16 

object-group network TEST
 group-object RFC1918
 group-object APIPA

Here, we took a brief look at network object groups. Object groups on the router also have a “service” option, which can be used to group protocols and ports. For those of you with a background configuring PIX / ASA, you may already be very familiar with configuring object groups. For the rest of you, it may be something that you want to practice before your next scheduled lab date.

Object groups were added in 12.4(20)T.

About Network Bulls Gurgaon

Which is best ccsp institute in delhi? cisco certified security professional training in delhi ncr gurgaon. Nb provides world class top training for cisco security firewall in delhi ncr. Cisco CCIE certification exam lab asia's biggest lab training institution in new delhi gurgaon india. There are many institutes in India, who claims to provide Job Guarantee after CCNA even. There are some small institutes, who make fool of students with there cheap tricks and frauds. Some institutes in this field, do not have CCIE Certified trainers and racks available, but they claim to provide best training from other big institutes. Student should not take admission in such fraud and cheap institutes. Students can also give their valuable feedback, complaints and reviews about different institutes in our forums. But students should also be aware of wrong and unauthenticated feedback or complaints against great institutes like Network Bulls, Networkers Home and INE in some fake complaint forums, where no one is authenticating any comment or posts. Those wrong posts are written by some competitor institutes only. Those cheap and fraud institutes can't earn money and get admissions based on their results and infrastructure. They just write rubbish and wrong things on different forums against some good institutes and try to get admissions. A student who want to get refunds or good training or want to give feedback, can also go to consumer court and register a complaint against that fraud institute.
As per my experience Network Bulls and INE are both the best institutes of world.
