Which two statements are true about STP and RSTP? (Choose two.)

A. STP uses a proposal-and-agreement handshake on point-to-point links instead of timers.

B. In RSTP, root ports and edge ports transition to the forwarding state immediately, without exchanging messages with other switches.

C. In RSTP, a TCN is generated when a port transitions to the discarding state.

D. In STP, the forwarding delay timer and maximum age timer define the convergence delay.

Which two events could cause the BGP Active state to appear? (Choose two.)

A. The local router does not have a route to the peer device.

B. The local router failed to establish a TCP connection with the peer device.

C. A firewall is stopping all UDP packets.

D. The BGP configuration is incomplete.

Switch 1 and Switch 2 are configured to run MSTP. However, MSTP is not working. Referring to the exhibit, which two actions will correct the problem? (Choose two.)

A. Configure interface ge-0/0/2 on Switch 2

B. Correct the bridge-priority parameter to be identical on both switches.

C. Configure revision-level 2 on Switch 1.

D. Correct the configuration-name parameter to be identical on both switches.

You are deploying IS-IS in your network to enable the routing of only IPv6. Assume that the loopback interface has been properly configured.

What is the minimum required configuration to enable only IPv6 routing in IS-IS?

A. user@host# show protocols isis rib-group inet6; interface ge-0/0/0.0; interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family inet6 address fd85:5944:1aee:026::1/64; }

B. user@host# show protocols isis interface ge-0/0/0.0; interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family iso; family inet6 address fd85:5944:1aee:026::1/64; }

C. user@host# show protocols isis no-ipv4-routing; interface ge-0/0/0.0 interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family iso; family inet6 address fd85:5944:1aee:026::1/64; }

D. user@host# show protocols isis no-ipv4-routing; interface ge-0/0/0.0; interface lo0.0 { passive; } user@host# show interfaces ge-0/0/0 unit 0 { family iso; family inet6; }

E. user@host# show protocols isis traffic-engineering { family inet6 { shortcuts; } } interface ge-0/0/0.0;

interface lo0.0 {

passive;

}

user@host# show interfaces ge-0/0/0

unit 0 {

family inet6 address fd85:5944:1aee:026::1/64;

Which protocol do two MC-LAG devices use to exchange control information?

A. VRRP

B. BFD

C. VCCP

D. ICCP

As frames are processed by a switch, which statement is true about how the switch builds its MAC table?

A. The source addresses fo the frames are associated with the inbound interface

B. The source addresses fo the frames are associated with the outbound interface

C. The destination addresses fo the frames are associated with the inbound interface

D. The destination addresses fo the frames are associated with the outbound interface

Which two interface names can be used within the Junos OS to reference GRE or IP-IP tunnels? (Choose two.)

A. gr-1/2/0.0

B. gre-1/2/0.0

C. ip-2/3/0.0

D. ipip-2/3/0.0

What is required on the egress and ingress devices to transport IPv6 traffic across an IPv4 network?

A. An IP-IP interface

B. A TE tunnel interface

C. A GRE tunnel interface

D. A 6to 4 tunnel interface

Click the Exhibit.

You have just configured a GRE tunnel, but you notice that the GRE tunnel is flapping. Referring to the exhibit, which two would you take to solve this problem? (Choose two.)

A. Add a specific static route to the local peer's network with the remote devices'loopback address as the next-hop gateway.

B. Add a specific route to the remote device's loopback address with the next-hop device defined as the next-hop gateway.

C. Set the GRE interface with a larger TTL value.

D. Remove the existing 192.168.2.0/30 static route.
