Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) Sample Questions (Q166-Q171):

NEW QUESTION # 166
Referring to the exhibit, which router will become the OSPF BDR if all routers are powered on at the same time?

Answer: C

Explanation:
Priority set to 0 will never become DR or BDR so R1 is excluded.
Higher priority is better in OSPF so R2 is lowest than both R3 and R4.
R3 and R4 has the same priority so RID will decide.
R4 has the highest RID so it will become DR and R3 will then become BDR.


NEW QUESTION # 167
Which OSPF packet type is sent when an OSPF router detects its database is stale?

Answer: D


NEW QUESTION # 168
How many bytes of overhead does an IP-IP tunnel add to a packet?

Answer: C


NEW QUESTION # 169
Which command solves the error that you see in the exhibit?

Answer: D

Explanation:
The error in the exhibit occurs because an access interface can only be a member of one VLAN, but it is currently configured with the "default" VLAN and is trying to be added to VLAN "v11." To resolve the issue, the correct command is:
delete ge-0/0/2 unit 0 family ethernet-switching vlan members default
This command removes the interface from the "default" VLAN, allowing it to be part of VLAN
"v11" as intended.


NEW QUESTION # 170
Which sequence correctly describes the basic message flow that leads to a successful BGP peering session?

Answer: C

Explanation:
RFC 4271 defines the BGP finite state machine as a strict, ordered progression of six states that a session must move through to successfully establish. A newly configured or reset session always begins in Idle, where BGP initializes resources and refuses connections until the ConnectRetry timer fires. From Idle, the router transitions to Connect and attempts to establish the underlying TCP transport session to the configured peer address on port 179. If that TCP attempt does not immediately succeed, the session falls back to the Active state, where the router continues retrying the TCP connection in the background; once the TCP handshake finally completes (from either Connect or Active), the session advances to OpenSent, during which the router transmits its own BGP OPEN message advertising its AS number, hold time, BGP identifier, and capabilities. Upon receiving and validating a compatible OPEN message from the peer, the session moves to OpenConfirm, where both sides exchange KEEPALIVE messages to confirm the parameters negotiated in the OPEN exchange are mutually acceptable. Only after this confirmation does the session reach Established, the final state in which UPDATE messages carrying actual routing information begin to flow between the peers. Any deviation from this Idle Connect -> Active -> OpenSent -> OpenConfirm Established ordering, as presented in the other answer choices, does not reflect the standardized BGP state machine.
