Juniper Networks Certified Internet Specialist (JNCIS-ENT) Set 6

A GRE tunnel is established between two routers. When a user on one end sends traffic with a large packet size to a user on the remote end, the packet never arrives. However, the problem does not exist for smaller packets. What is the problem?

You have created an IP-IP tunnel which will traverse interface at-0/1/0 and you would like to make sure that the tunnel is operational. Which operational-mode command should you use to verify that the IP-IP tunnel interface is up?

You want to configure a redundant trunk group on a switch. You want ge-0/0/0.0 to be the default link; however, if ge-0/0/0.0 fails and the switch begins using ge-0/0/1.0, you want the switch to continue using ge-0/0/1.0 until ge-0/0/1.0 fails. Which configuration will accomplish this scenario?

Which statement is correct regarding the VLAN factory-default configuration on an EX Series switch?

Under which hierarchy do you configure OSPF?

You add a GRE tunnel to transport packets between two routers. After implementing this, you notice an increase in the number of dropped packets. While looking at packet captures, you notice that the do-not-fragment (DF) bit is set in the IP header of all the dropped packets. What would cause this changed behavior?

Which type of port must be an 802.1Q tagged port?

You want to allow RIP routes to be redistributed by an ASBR into the connected OSPF area, but you do not want to recieve external routes from other OSPF areas. Which OSPF area type would be used to satisfy the requirement?

What is a difference between a generated route and an aggregated route?

Two routers have established a peering using EBGP over a single T1 link. How often will the routing table be synchronized between the two routers?
