LINX 2 example questions
1) Tick the best answer. What would be the best aggregation of the following addresses Over summarisation is NOT to be used.

192.168.192.0/24
192.168.193.0/24
192.168.194.0/24
192.168.195.0/24

These addresses cannot be aggregated as they already have a mask.
A - 192.168.192.0/30
B - 192.168.192.0/23 and 192.168.194.0/23
C - 192.168.192.0/21
D - 192.168.192.0/20

question two image - two routers

2) Tick all that apply with regard to the diagram above

A - It will all work fine without any changes.
B - The hello intervals are configured at too lower a number (it should be a minimum of 10 seconds).
C - The router dead intervals are too low they should be a minimum of 4 times the hello interval.
D - The mismatch in hello intervals will lead to intermittent problems when the link is congested.
E - R1 can ping the remote serial interface (10.2.1.2).
F - Hello packets will be sent by R1 every 6 seconds.
G - Hello packets will be sent by R2 every 21 seconds.
H - If a Link State Advert is not received by R1 within 18 seconds then those networks are marked as dead.
I - With the configuration above routers R1 and R2 will become neighbours on receipt of each others hello packets.
J - With the configuration above routers R1 and R2 will NOT become neighbours on receipt of each others hello packets.

3) Tick the best answer. Which is true with regard to VLANS.

A - Inter VLAN traffic is normally forwarded based on layer 2 addresses.
B - Switches use VLANS as the principle means of creating separate collision domains.
C - Routers use VLANS as their principle means of creating separate broadcast domains in a routed network.
D - 802.1Q must be supported by PCs if VLANS are being used.
E - ARP packets will cross multiple VLANS.
F - The 802.1Q server IP address should be the default gateway for PCs when VLANs are used.
G - None of the above.
