Juniper Enterprise Routing and Switching, Specialist (JNCIS-ENT) Sample Questions (Q194-Q199):

NEW QUESTION # 194
Which two types of tunnels are able to be created on all Junos devices? (Choose two.)

Answer: B,D


NEW QUESTION # 195
What is a purpose of using a spanning tree protocol?

Answer: C

Explanation:
A broadcast storm is a network condition where a large number of broadcast packets are sent and received by multiple devices, causing congestion and performance degradation. A broadcast storm can occur when there are loops in the network topology, meaning that there are multiple paths between two devices.
A spanning tree protocol is a network protocol that prevents loops from being formed when switches or bridges are interconnected via multiple paths. It does this by creating a logical tree structure that spans all the devices in the network, and disabling or blocking the links that are not part of the tree, leaving a single active path between any two devices.
By eliminating loops, a spanning tree protocol also eliminates broadcast storms, as broadcast packets will not be forwarded endlessly along the looped paths. Instead, broadcast packets will be sent only along the tree structure, reaching each device once and avoiding congestion.


NEW QUESTION # 196
Referring to the exhibit, which two statements are correct? (Choose two.)

Answer: C,D


NEW QUESTION # 197
Click the Exhibit button. You have three Juniper Networks EX Series Switches in an STP domain as shown in the exhibit. Which statement describes the switch that will be elected as the root bridge?

Answer: A

Explanation:
Root bridge election in Spanning Tree Protocol is governed entirely by the Bridge Identifier, an 8- byte value formed by concatenating the configured bridge priority (the higher-order, more significant portion of the comparison) with the switch's MAC address (used strictly as a tiebreaker when priorities are identical). Every participating switch compares Bridge IDs, and the switch advertising the numerically lowest Bridge ID is elected root. In this exhibit, the three switches have distinctly different priority values -- EX-1 at the Junos/IEEE default of 32768, EX-2 at 8192, and EX-3 at 16384 -- meaning the comparison is decided entirely at the priority stage and never needs to proceed to a MAC address tiebreak at all. Since 8192 is numerically the lowest of the three priority values, EX-2 is elected root bridge purely on the strength of its lower priority, regardless of what its MAC address happens to be. This is precisely why the correct answer cites priority rather than MAC address as the deciding factor: MAC address only becomes relevant as a tiebreaker in the specific case where two or more switches share an identical priority value, which is not the situation presented here. Understanding that priority is evaluated first and is independently sufficient to decide the outcome whenever it differs is a foundational and heavily tested Spanning Tree concept on the JNCIS-ENT exam.


NEW QUESTION # 198
What is the default keepalive time for BGP?

Answer: B

Explanation:
The default hold-time is 90 seconds, meaning that the default frequency for keepalive messages is 30 seconds.
