質問 # 105
You are using OSPF to advertise the subnets that are used by the Denver and Dallas offices. The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets.
Referring to the exhibit, which two statements are correct? (Choose two.)
正解：A、B
解説：
The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets. This can be resolved by redistributing the connected subnets into OSPF.
Option C suggests to configure and apply a routing policy that redistributes the connected Dallas and Denver subnets. This is correct because redistribution allows routes from one routing protocol to be communicated to another, and in this case, it allows the connected subnets to be advertised through OSPF.
Option D suggests enabling the passive option on the OSPF interfaces that are connected to the Dallas and Denver subnets. This is also correct because in OSPF, a passive interface is an interface that belongs to the OSPF router, but does not send OSPF Hello packets. It's typically used on an interface that you don't want to use for OSPF adjacencies, but you still want to advertise its IP address. Therefore, enabling passive interface can help in advertising the Dallas and Denver subnets.
質問 # 106
Which two statements are correct about IS-IS? (Choose two.)
正解：A、D
質問 # 107
Which statement is correct about controlling the routes installed by a RIB group?
正解：C
解説：
When routes are placed into a RIB group, an import policy can be applied to determine which routes are accepted into that group. This policy helps in controlling which routes get installed or filtered into the RIB group from various sources like other routing protocols or static routes.

質問 # 108
You have traffic for a video streaming application traversing a GRE tunnel in your network and users are reporting poor performance. Both ends of the tunnel are using the default settings for a gigabit Ethernet interface, but you observe excessive packet drops due to exceeding the MTU.
Which two steps would you take to improve connectivity for this application? (Choose two.)
正解：A、B
解説：
The described symptom -- excessive packet drops specifically attributed to exceeding the MTU on a GRE tunnel carrying full-size video streaming traffic across default-MTU gigabit Ethernet interfaces -- is a direct consequence of the 24 bytes of GRE encapsulation overhead pushing packets that were already at or near the standard 1500-byte Ethernet MTU past the physical interface's transmission limit once the outer GRE and IP headers are added. The most durable fix is to proactively increase the physical member interfaces' MTU beyond the 1500-byte default -- to
1524 bytes or higher -- which provides sufficient headroom to absorb the full GRE encapsulation overhead without ever causing the fully encapsulated packet to exceed the interface's transmission capability, allowing full-size 1500-byte payloads to pass through the tunnel intact and without fragmentation or drops. As a complementary measure, configuring the clear-dont- fragment-bit option on the tunnel or member interfaces instructs Junos to clear the DF (don't fragment) bit on oversized packets rather than dropping them outright when they do exceed the available MTU, allowing the Packet Forwarding Engine to fragment and later reassemble the traffic instead of silently discarding it, which directly addresses the reported packet loss even under transient conditions. Simply raising the MTU only to 1500 bytes fails to account for the 24- byte GRE overhead and would not resolve the underlying oversize condition. Routing the tunnel over a higher-bandwidth link addresses potential congestion but does nothing to correct an MTU- based packet-size violation, which is the root cause explicitly identified in this scenario.
質問 # 109
Which three actions are required for filter-based forwarding? (Choose three.)
