質問 # 206
What is the maximum allowable MTU size for a default GRE tunnel without IPv4 traffic fragmentation?
正解：A
解説：
The maximum allowable MTU size for a default GRE tunnel without IPv4 traffic fragmentation is
1476 bytes. This is because GRE packets are formed by the addition of the original packets and the required GRE headers. These headers are 24-bytes in length and since these headers are added to the original frame, depending on the original size of the packet we may run into IP MTU problems. The most common IP MTU is 1500-bytes in length (Ethernet). When the tunnel is created, it deducts the 24-bytes it needs to encapsulate the passenger protocols and that is the IP MTU it will use. For example, if we are forming a tunnel over FastEthernet (IP MTU 1500) the IOS calculates the IP MTU on the tunnel as: 1500-bytes from Ethernet-24-bytes for the GRE encapsulation = 1476-Bytes.
質問 # 207
Which statement describes how nonstop active routing (NSR) maintains routing protocol information during a Routing Engine switchover?
正解：A
解説：
Nonstop active routing's defining architectural feature is that the backup Routing Engine runs a fully live, active instance of the routing protocol daemon (rpd) in parallel with the primary Routing Engine's rpd instance, continuously, from the moment NSR and its prerequisite GRES are established -- not merely at the instant a switchover begins. As protocol adjacencies form, routes are learned, and the RIB is updated on the primary Routing Engine, that same protocol and RIB state is mirrored in real time to the backup Routing Engine's rpd process through an internal synchronization mechanism, so the backup's protocol state remains a live, up-to-date replica of the primary's at essentially every moment during normal operation. When a switchover occurs, the backup Routing Engine simply assumes the primary role with protocol adjacencies, routing tables, and forwarding state already fully populated and current, allowing it to continue operating without re-establishing neighbor relationships or re-learning the network topology, which is what makes the switchover genuinely nonstop and invisible to neighboring routers. This is fundamentally different from graceful restart, where the restarting router must rebuild its state by requesting help from cooperating neighbors after the fact. The Packet Forwarding Engine plays no role in synchronizing protocol-layer information such as LSAs or BGP updates; that is strictly an rpd-to-rpd function coordinated through the Routing Engine synchronization infrastructure.
質問 # 208
Which two types of tunnels are able to be created on all Junos devices? (Choose two.)
正解：C、D
質問 # 209
Which two statements are true about high availability on Junos devices? (Choose two.)
正解：A、D
質問 # 210
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.
