問題 #93
Which statement is correct concerning exception traffic processing?
答案：C
解題說明：
Exception traffic refers to packets that the Packet Forwarding Engine (PFE) cannot process normally and must be forwarded to the Routing Engine (RE) for further processing. This includes packets destined for the router itself or packets needing special handling that the PFE cannot provide. To protect the RE from being overwhelmed by such traffic, which could potentially impact the router's control plane functions, exception traffic is rate-limited. This means that there's a threshold to how much exception traffic can be sent to the RE, ensuring that the router's critical management and control functions remain stable and responsive even during high traffic volumes or attacks.
問題 #94
Exhibit:
Referring to the exhibit, which routing configuration is required for these two users to access the remote server?
答案：C
解題說明：
The network topology illustrates two distinct IP subnets, 10.1.1.0/24 and 10.1.2.0/24 , separated by a Layer 3 router. For hosts on the first subnet to communicate with the server on the second subnet, an intermediary device must perform inter-subnet routing. The router acts as the exit point for each local segment, utilizing its interfaces assigned with the .254 host address as the logical path to external networks.
The fundamental requirement for this communication is the configuration of a default gateway on all end- nodes. When the users (on 10.1.1.0/24 ) attempt to send data to the server (on 10.1.2.0/24 ), their local TCP/IP stack recognizes the destination is not on the local wire. Without a defined default gateway, the hosts would simply drop the traffic as unroutable. By setting the default gateway to 10.1.1.254 for users and 10.1.2.254 for the server, the hosts are instructed to forward all off-net traffic to the router. The router then consults its routing table-which contains these directly connected routes-and forwards the packets to the appropriate egress interface. While VLAN tagging or routing protocols could exist in more complex environments, the primary necessity for basic reachability between these two specific segments is a correctly configured gateway on the terminal devices.

問題 #95
Which command is used to enter configuration mode from operational mode?
答案：B
解題說明：
The configure command transitions the CLI from operational mode into configuration mode, allowing changes to the candidate configuration.
問題 #96
Which statement is correct about traffic flow in the network shown in the exhibit?
答案：A
解題說明：
The configuration exhibit demonstrates a classic scenario where mismatched static routing leads to a routing loop . Router R1 is configured with a default route ( 0.0.0.0/0 ) pointing to R2 as its next hop. Conversely, R2 is configured with a broad static route for 10.1.0.0/16 pointing back to R1 .
If a user sends a packet to an unassigned IP address such as 10.1.99.1 , the following sequence occurs:
* R1 receives the packet and consults its routing table. Finding no specific match for the 10.1.99.1 host, it uses the default route and forwards the packet to R2 .
* R2 receives the packet and identifies that 10.1.99.1 falls within its defined static route for 10.1.0.0/16 .
* Following its configuration, R2 forwards the packet back to R1 . This process repeats indefinitely-or until the packet ' s Time to Live (TTL) reaches zero-because the broad summary on R2 encompasses addresses that R1 does not actually have a local path for. This illustrates the critical importance of ensuring that summary routes or default routes do not overlap in a way that creates circular forwarding paths for non-existent destinations.

問題 #97
What is the primary purpose of an IPv6 link-local address?
答案：A
解題說明：
IPv6 link-local addresses, which are identified by the fe80::/10 prefix, are a mandatory component of the IPv6 architecture. The primary purpose of a link-local address is to enable immediate communication between devices located on the same local network segment (the same "link") without the requirement for a global unicast address or an external routing infrastructure. These addresses are non-routable, meaning they are never forwarded by a router to another network segment.
Every IPv6-enabled interface on a Junos device automatically generates a link-local address, typically derived from the interface's MAC address using the EUI-64 format or a stable privacy algorithm. These addresses are essential for several core functions: they are used by the Neighbor Discovery Protocol (NDP) to resolve MAC addresses, they serve as the source address for routing protocol adjacency formation (such as OSPFv3 or RIPng), and they are frequently used as the next-hop address in IPv6 routing tables. While they do not provide Layer 2 connectivity themselves (which is the role of the MAC address), they provide the necessary Layer
3 link-level presence required for nodes to discover one another and communicate across the physical medium before any global addressing is configured.
