Consider the following diagram. Assuming that all the necessary configuration has already been done on R2 (proxy-arp is disabled), to communicate from a device on LAN1 to a device on LAN2, which of the following configurations on R1 would enable this?

• A. /ip route add dst-address=0.0.0.0/0 gateway=192.168.99.2

• /ip route add dst-address=192.168.0.0/24 gateway=192.168.0.1

• /ip route add dst-address=0.0.0.0/0 gateway=Ether1

• /ip route add dst-address=192.168.1.0/24 src-address=192.168.0.0/24 gateway=192.168.99.2

• /ip route add dst-address=192.168.1.0/24 gateway=192.168.99.2

Which route will be used to reach host 192.168.1.55?

/ip route

add disabled=no distance=1 dst-address=192.168.1.0/24 gateway=1.1.1.1

add disabled=no distance=1 dst-address=192.168.1.0/25 gateway=2.2.2.2

add disabled=no distance=1 dst-address=192.168.0.0/16 gateway=3.3.3.3

• Route via gateway 3.3.3.3

• Route via gateway 2.2.2.2

• Route via gateway 1.1.1.1

Router has two gateways to reach a certain network both with check gateway activated. Choose the option you can use to control active and backup gateway

When sending out an ARP request, an IP host is expecting what kind of address for an answer?

• 802.11g

• IP Address

• MAC Address

• VLAN ID

If route type is 'blackhole', then packets to the destination network are going to be

• dropped on this router

• sent back to the source

• dropped on this router and ICMP message will be sent back to the source

• sent back to the previous router

/ip route configuration on router,

/ip route add gateway=192.168.0.1

/ip route add dst-address=192.168.1.0/24 gateway=192.168.0.2

/ip route add dst-address=192.168.2.0/24 gateway=192.168.0.3

/ip route add dst-address=192.168.3.0/26 gateway=192.168.0.4

Router needs to send packets to 192.168.3.240. Which gateway will be used?

• 192.168.0.1

• 192.168.0.3

• 192.168.0.4

• 192.168.0.2

The 'check-gateway' option is enabled for one route. Select all statements that are true:

• In case of failure of the gateway, routes pointing to that gateway will become inacti

• Check gateway option can be configured for Ping, ARP and RARP (reverse ARP)

• Gateway is checked every 10 seconds and after a single failure, the gateway is considered unreacheable

• Gateway is checked every 10 seconds and after 2 failures, the gateway is considered unreacheable

You have a router with configuration

- Public IP :202.168.125.45/24

- Default gateway:202.168.125.1

- DNS server: 248.115.148.136, 248.115.148.137

- Local IP: 192.168.2.1/24

Mark the correct configuration on client PC to access to the Internet

• IP:192.168.2.253/24 gateway:202.168.0.1

• IP:192.168.2.2/24 gateway:202.168.125.45

• IP:192.168.1.223/24 gateway:248.115.148.136

• IP:192.168.2.115/24 gateway: 192.168.2.1

• IP:192.168.0.1/24 gateway:192.168.2.1

Which are correct ECMP routes (mark all that apply):

• dst-addr=0.0.0.0/0 gateway=10.1.1.1,10.1.1.1,10.2.2.2

• dst-addr=0.0.0.0/0 gateway=10.1.1.1

• dst-addr=0.0.0.0/0 gateway=10.1.1.1,10.1.1.1

• dst-addr=0.0.0.0/0 gateway=10.1.1.1,10.2.2.2

When using routing option 'check-gateway=ping' what is the ICMP echo request interval (in seconds)?

• 20s

• 30s

• 60s

• 10s
