JN0-104 JNCIA Practice Test
Questions and Answers7
If a packet is destined to an address that is not in the forwarding table: - ANSWERS-the packet is
rejected and an ICMP (Internet Control Message Protocol) network unreachable message is sent
to the source address
2 true statements about dynamic routing: - ANSWERS-Devices dynamically learn routing info
from each other, Allows a device to automatically reroute traffic around a failure
on a show route command the square brackets contain info like:
[Static/5] or [Direct/0]. What does the number represent - ANSWERS-route preference
[route source protocol/route protocol preference]
BGP default behavior for importing and exporting routes - ANSWERS-import all BGP routes into
inet.0 routing table
export active BGP routes to configured BGP peers
route filer (routing policy) has this component: - ANSWERS-term,, then-accept
terms are building blocks for all juniper policies
routing policies contain these 2 typs of statements: - ANSWERS-then, from
longer route-filter match type? - ANSWERS-all routes within a specified prefix that are longer
than the given prefix are considered a match
, Discard action on a firewall filter - ANSWERS-silently drops the packet
If a route does not match any user-configured policies? - ANSWERS-The route is sent to the
default protocol policy
Three statements that describe Transmission Control Protocol?
-Uses a best effort delivery approach
-had delivery notification and error-checking mechanisms
-applications include HTTP and SMTP
-TCP is faster that User Data Datagram Protocol (UDP)
-TCP is a transport layer protocol - ANSWERS-has delivery notification and error-checking,
applications include HTTP and SMTP
TCP is transport layer protocol
Two benefits of the disaggregated JUNOS OS?
A-The Junos VM becomes hardware-independent and can be deployed on any hypervisor
without modifications.
B-Platform drivers and forwarding engine are removed from the control plane to 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 - ANSWERS-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
