質問 # 64
Your router receives two BGP routes for the same prefix. One route is learned from an IBGP neighbor, and the other route is learned from an EBGP neighbor.
By default, which route will be selected as active in this scenario?
正解：B
解説：
Once the two candidate routes have equal route preference and equal local preference (both defaulting to 100 unless modified by policy), the Junos BGP algorithm proceeds to its third decision step, which compares the length of each candidate's AS path attribute and selects whichever path carries the shortest AS path, since a shorter path is interpreted as traversing fewer autonomous system hops to reach the origin. This step occurs well before the algorithm ever reaches the specific EBGP-over-IBGP preference rule, which is only evaluated later, after local preference, AS path length, origin type, and MED have all already been compared and found equal between the candidates; because an IBGP-learned copy of a route typically retains the identical AS path that was originally received from the external AS (IBGP does not prepend the local AS number the way crossing an AS boundary does), it is entirely possible, and often the deciding scenario, for AS path length to differ between competing paths well before the algorithm would ever need to fall back on the IBGP-versus- EBGP tiebreak. Selecting a route purely because it was 'learned through IBGP' is not a rule that exists anywhere in the algorithm and would in fact typically be the opposite of Junos's later EBGP-preference tiebreak. Neither next-hop IP address value nor router ID value is compared with a 'highest wins' rule at any point in the standard path selection sequence - where router ID is used at all, Junos prefers the lowest value, not the highest, making both of those distractors doubly incorrect.

質問 # 65
Which two types of tunnels are able to be created on all Junos devices? (Choose two.)
正解：A、B
解説：
GRE tunnels can be created on all Junos devices. GRE is a tunneling protocol that encapsulates a wide variety of network layer protocols inside virtual point-to-point links.
IP-IP tunnels can also be created on all Junos devices. IP-IP tunneling is used to encapsulate IP packets within IP packets, providing a simple way to tunnel IP traffic.
質問 # 66
Referring to the exhibit, which router will become the OSPF BDR if all routers are powered on at the same time?
正解：B
解説：
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.
質問 # 67
Which statement is correct about graceful Routing Engine switchover (GRES)?
正解：A
解説：
The Graceful Routing Engine Switchover (GRES) feature in Junos OS enables a router with redundant Routing Engines to continue forwarding packets, even if one Routing Engine fails.
GRES preserves interface and kernel information, ensuring that traffic is not interrupted.
However, GRES does not preserve the control plane.
To preserve routing during a switchover, GRES must be combined with either Graceful Restart protocol extensions or Nonstop Active Routing (NSR). When GRES is combined with NSR, nearly
75 percent of line rate worth of traffic per Packet Forwarding Engine remains uninterrupted during GRES. Any updates to the primary Routing Engine are replicated to the backup Routing Engine as soon as they occur.
Therefore, when GRES is combined with NSR, routing is preserved and the new master RE does not restart rpd.
質問 # 68
What is a purpose of using a spanning tree protocol?
正解：B
解説：
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.
