In OSPF interface configuration what effect will a passive=yes option have on a specific interface ?

• It will prevent all OSPF traffic through that interface

• It will action a mirroring of all routing upgrades to that interface

• It will prevent all traffic through that interface

• It will prevent routes learned through the interface from being listed in the routing table.

When is Bridge Control Protocol (BCP) used?

• When a loop-free bridged network (a substitution for Spanning Tree protocols) is needed

• To bridge wireless WDS interfaces

• To pass Layer 2 ethernet frames to PPP type interfaces

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

• SSTP or L2TP/IPsec

• EoIP over SSTP or over L2TP/IPsec

• SSTP with BCP or L2TP/IPsec with BCP

• EoIP with IPsec secret specified

Which of the following conditions have to be fulfilled for two routers on one ethernet segment to become ospf neighbors?

• Hello and dead timers must be the same

• MTU must be the same

• Network-type must be the same

• Cost must be the same

What is policy routing for and what criteria can be used to decide appropriate route?

• Policy routing can be used to force specific traffic to go different way through network, but only source and destination address can be used to distinguish traffic.

• Policy routing can be used to force specific traffic to go different way through network and beside source and destination address any traffic that can be marked in firewall can be used to distinguish traffic.

• Policy routing can be used to bypass routing table and is possible only if BGP is enabled.

• Policy routing can be used to bypass routing table and only active tunnel interfaces can be used to direct traffic alternatively.

EOIP tunnels can not be bridged because they are not true layer 2 tunnels.

• True

• False

There are two PPPoE stages, Discovery and Session.

• False

• True

Select true statements about PPTP/PPPoE server.

• PPTP server can be bound to one single interface

• PPTP server is reachable on all ip adresses

• PPPoE server can be bound to one single interface

• PPPoE server is reachable via all active interfaces

There are two gateways to the Internet in a network on two separate routers. Both of them have OSPF routing enabled and are redistributing their default gateways to the network respectively. One does it as type 1, the other as type 2, cost configuration is the same on both routers. What will be preferred gateway in the network?

• MikroTik RouterOS does not distinguish types when redistributing default route. RouterOS relies only on cost, so route from the closest router in term of cost will be chosen

• The route distributed as type 1 will be the preferred one

• The route distributed as type 2 will be the preferred one

• Traffic to Internet will be load-balanced between the two routes as routes from both routers will be installed in routing tables

The OSPF network is configured as on the attached figure. Each of the links has cost sets as on the figure. If we configure redistribution of default route on router A with command:

/routing ospf instance set 0 distribute-default=always-as-type-2 metric-default=5

What will be the cost of the default route on router B?

• 5

• 25

• 26

• 35
