,1.When an agent installation is successful, devices are placed into which state using
the Juniper Apstra Ul?
A. IS-MAINT
B. OOS-READY
C. OOS-QUARANTINED
D. IS-ACTIVE
Answer: B
Explanation:
When an agent installation is successful, devices are placed into the Out of Service
Quarantined (OOS-QUARANTINED) state using the Juniper Apstra UI. This state
means that the device is not yet managed by Apstra and has not been assigned to
any blueprint. The device configuration at this point is called Pristine Config. To make
the device ready for use in a blueprint, you need toacknowledge the device, which
e
as
changes its state to Out of Service Ready (OOS-READY)12.

You are working to build an ESI-LAG for a multihomed server. The ESI-LAG is not
en

S
coming up as multihomed.
Referring to the exhibit, what are two solutions to this problem? (Choose two.)
A. The gateway IP addresses on both devices must be different.
B. The LACP system ID on both devices must be the same.
C. The loopback IP addresses on both devices must be the same.
D. The ESI ID on both devices must be the same.
Answer: B D
Explanation:
According to the Juniper documentation1, an ESI-LAG is a link aggregation group
(LAG) that spans two or more devices and is identified by an Ethernet segment
identifier (ESI). An ESI-LAG provides redundancy and load balancing for a
, multihomed server in an EVPN-VXLAN network.
To configure an ESI-LAG, you need to ensure that the following requirements are
met:
- The LACP system ID on both devices must be the same. This ensures that the
LACP protocol can negotiate the LAG parameters and form a single logical interface
for the server.
- The ESI ID on both devices must be the same. This ensures that the EVPN control
plane can advertise the ESI-LAG as a single Ethernet segment and synchronize the
MAC and IP addresses of the server across the devices.
- The VLAN ID and VNI on both devices must be the same. This ensures that the
server can communicate with other hosts in the same virtual network and that the
VXLAN encapsulation and decapsulation can work properly.
In the exhibit, the LACP system ID and the ESI ID on both devices are different, which
e
as
prevents the ESI-LAG from coming up as multihomed. Therefore, the correct answer
B
ps
um
is B and D. The LACP system ID on both devices must be the same and the ESI ID
D
om
on both devices must be the same.
