A GRE tunnel is configured between Router1 and Router2 across the Internet. Performance on the GRE tunnel is slow and Router1 is receiving ICMP messages from Router2.

What is the cause of this problem?

  1. The do-not-fragment (DF) bit has not been set on Router2.

  2. The do-not-fragment (DF) bit has not been set on Router1.

  3. There is a duplex setting mismatch on the GRE tunnel.

  4. The maximum segment size (MSS) setting has not been configured correctly for the GRE tunnel.

Answer: D

then accept;

}

}

– Exhibit –

Referring to the exhibit, there is an OSPF policy to redistribute static routes. Which routes will be propagated to OSPF neighbors?

A. 172.29.130.0/17 172.29.13.0/24

172.20.16.0/12

B. 172.29.13.0/24 172.29.20.0/24

C. 172.29.130.0/17 172.29.13.0/24

Answer: D

Question No: 380 – (Topic 4)

– Exhibit – Router A.

interfaces { ge-0/0/0 { unit 0 { family inet {

address 192.168.1.20/24 { vrrp-group 27 {

virtual-address 192.168.1.20;

priority 255;

authentication-type simple; authentication-key lt;juniper123gt;;

}

}

}

}

}

}

Router B.

interfaces { ge-4/2/0 { unit 0 {

family inet {

address 192.168.1.19/24 { vrrp-group 27 {

virtual-address 192.168.1.20;

priority 200;

authentication-type simple; authentication-key lt;juniper123gt;;

}

}

}

}

}

}

– Exhibit –

Referring to the exhibit, Router B comes up first and preemption is not enabled. Router A assumes mastership for the virtual IP. Why does Router A assume a mastership role for the IP?

  1. Router A#39;s interface IP address and the virtual IP address match.

  2. Router A is configured with a higher priority.

  3. Router B is configured with a lower priority.

  4. Router B has a lower primary IP address for the interface.
