Sample JNCIP-ENT practice questions
5 questions taken from the JNCIP-ENT mock tests on Wrexa Edge. Try each one, then reveal the answer.
-
Q1. Which Junos CoS component maps incoming DSCP values to forwarding classes and loss priorities?
- Rewrite rule
- Scheduler map
- Drop profile
- Behavior aggregate (BA) classifier
Show answer
Answer: D — Behavior aggregate (BA) classifier
BA classifiers read existing markings (DSCP, IP precedence, 802.1p, EXP); rewrite rules re-mark on egress.
-
Q2. Which Junos routing-instance type is used for a PE customer VRF in an L3VPN?
- instance-type vrf
- instance-type virtual-router
- instance-type vpls
- instance-type forwarding
Show answer
Answer: A — instance-type vrf
vrf instances need an RD, vrf-target (or import/export policies) and PE-CE interfaces; virtual-router has no MP-BGP VPN signalling.
-
Q3. Which community definition matches any community whose AS portion is 65000?
- members *:65000
- members 65000:*
- members 65000:.$
- members ^65000$
Show answer
Answer: B — members 65000:*
Junos community members support wildcards and regular expressions per field; 65000:* matches all values for that AS.
-
Q4. What is the risk of assigning a large-volume queue strict-high priority without a limit?
- It can disable the BA classifier
- It can reset the drop profiles
- It can starve lower-priority queues
- It can remark all other traffic to BE
Show answer
Answer: C — It can starve lower-priority queues
Strict-high is serviced before other queues; without shaping or rate-limit it can consume all bandwidth.
-
Q5. By default, how are IS-IS Level 2 routes propagated into a Level 1 area?
- They are leaked as L1 routes with the up/down bit
- They are leaked only when wide metrics are enabled
- They are leaked as external routes with metric 0
- They are not; L1 routers use the attached bit default
Show answer
Answer: D — They are not; L1 routers use the attached bit default
L1 areas are stub-like: L1/L2 routers set the attached bit and L1 routers install a default. L2-to-L1 leaking requires an export policy (setting the up/down bit).
