hypervisor without modifications.

increase performance.
C-Increased flexibility to use different control plane versions
D-The architecture facilitates programmability through provisioning the control
plane, the data path and the platform API
B and D
Describes the connection between control plane and forwarding plane
-No rate limiter is configured by default
-control traffic is preferred over exception traffic during congestion
-A rate limiter is configured by default
-Exception traffic is preferred over control traffic during congestion
Control traffic is preferred, a rate-limiter is configured by default
The JUNOS OS sends all exception traffic destined for the RE over the internal link that
connects the control and forwarding plane. The JUNOS OS rate limits the exception
traffic traversing the internal link to protect the RE from DOS attacks. During congestion
preference is given to local and control traffic destined for the RE
A packet enters a JUNOS device. No matching destination entry exists in the
forwarding table. How will the device respond?
The PFE responds to the source with a destination unreachable message. The PFE, not
the RE
Two examples of transit traffic:
A-SCP traffic destined for the router's loopback interface
B-SFTP traffic that enters and exits the same interface on a local router
C-SCP traffic that enters one interface and exits another on a local router
D-SFTP traffic that enters one interface and is destined for another on a local
router
B, C transit traffic is destined for the local router
When a system process encounters an error, how does the JUNOS OS protect
other processes from being affected?
Each process operates in its own shared memory space
