Settings in /ppp secret user database override corresponding /ppp profile settings

• True
• False

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 2.2.2.2
• Route via gateway 1.1.1.1
• Route via gateway 3.3.3.3

EoiP is:

• Layer-3 tunnel
• MikroTik proprietary tunnel protocol
• Layer-2 tunnel, that can be bridged

When is Bridge Control Protocol (BCP) used?

• To bridge wireless WDS interfaces
• To pass Layer 2 ethernet frames to PPP type interfaces
• When a loop-free bridged network (a substitution for Spanning Tree protocols) is needed

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

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?

• /ip route add dst-address=192.168.1.0/24 gateway=192.168.99.2
• /ip route add dst-address=0.0.0.0/0 gateway=192.168.99.2
• /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=192.168.0.0/24 gateway=192.168.0.1

To securely bridge (Layer 2) together two remote networks the following methods can be used:

• SSTP or L2TP/IPsec
• EoIP with IPsec secret specified
• EoIP over SSTP or over L2TP/IPsec
• SSTP with BCP or L2TP/IPsec with BCP
• IPIP with IPsec secret specified

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

• Check gateway option can be configured for Ping, ARP and RARP (reverse ARP)
• Gateway is checked every 10 seconds and after 2 failures, the gateway is considered
• Gateway is checked every 10 seconds and after a single failure, the gateway is considered
• In case of failure of the gateway, routes pointing to that gateway will become inactive

There are two routes in the routing table: 0 dst-addr=10.1.1.0/24 distance=10 gateway=10.10.10.10 1 dst-addr=10.1.1.4/30 distance=20 gateway=10.20.20.20 Which gateway will be used to send packet with destination IP address 10.1.1.6

• both
• 10.20.20.20
• 10.10.10.10
• none, because distance is >= 10

To create a route to a different network, e.g. 192.168.0.0/24, which of the following can be used as a gateway from your network?

• ether1 with a larger than /32 address space
• pppoe-out1
• 192.168.100.1
• 192.168.0.1
