} } } } }
}
— 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?

An IP tunnel connects two routers over the Internet as shown in the exhibit.
Which two statements are correct? (Choose two.)

SITE1:
routing-options {
autonomous-system 65001;
}
protocols {
bgp {

group 65002 {

}
SITE2:

}
protocols {
bgp {
group 65001 {
neighbor 10.200.12.2 {
peer-as 65003;
} } }
}
— Exhibit —
Referring to the exhibit, SITE1 is configuring an EBGP peering with SITE2. SITE2 configured the
incorrect peer AS during a maintenance window and now is unable to change the configuration
until the next maintenance window.
Which configuration would you use on SITE1 to establish the EBGP peering?

The exhibit shows the RSTP configuration for your EX Series switch. The switch begins receiving
BPDUs on a port and disables that port.
Which port is disabled?

Your current network is using Switch-1 and Switch-2 as a Layer 3 core pair. You change the EX
series switch core into a VC and configure the links between the switches to be a LAG.
Assuming that Switch-3 is operating at Layer 2 only, which two protocols would be removed from
this portion of the network? (Choose two.)

Referring to the exhibit, what will the mac-move-limit command on ge-0/0/6 do?

A network administrator has connected four switches as shown in the exhibit. The switches are at
their factory-default configurations and the administrator powers on all of the switches at the same
time.
Which switch will become the root bridge?

— Exhibit —
You have configured a MAC limit on your switch.

Referring to the exhibit, when the MAC limit is exceeded, when will the port recover?
