質問 # 41
Which Junos OS feature allows an administrator to revert the system configuration to a previously saved state in case of errors or misconfiguration?
正解：D
解説：
The "rollback" feature allows administrators to revert to earlier configuration versions stored in the system. Junos maintains multiple rollback files, making it easy to recover from errors. This feature is critical for maintaining network stability and quick recovery.
質問 # 42
Which Junos OS architecture component is responsible for maintaining routing protocol processes separately from the packet forwarding process?
正解：B
解説：
The Routing Engine handles control plane functions such as routing protocol processes, system management, and user access, keeping them separate from the Packet Forwarding Engine, which handles the data plane.

The MX204 has 12 built-in ports. Referring to the exhibit, to which interface does the arrow point?
正解：B
解説：
The Juniper MX204 is a fixed-configuration router that utilizes a specific hierarchical naming convention for its physical interfaces: type-fpc/pic/port. In the MX204 architecture, there is a single built-in Flexible PIC Concentrator (FPC), which is always designated as FPC 0 . This FPC is subdivided into two logical Physical Interface Cards (PICs): PIC 0 and PIC 1 .
As shown in the exhibit, PIC 0 contains four high-speed ports (labeled 0/0 through 0/3) that typically support
40GbE or 100GbE speeds. PIC 1 contains eight ports (labeled 1/0 through 1/7) designed for 1GbE or 10GbE connectivity. These ports are arranged in a stacked, $2 \times 4$ grid. The labeling system on the chassis indicates the port numbers for each column. In the fourth column of the PIC 1 block, the top port is identified as 1/6 and the bottom port as 1/7 .
The blue arrow in the exhibit points directly to the bottom-right interface in the PIC 1 section. Correlating this physical location with the chassis labels confirms that the port number is 7. When combined with the FPC and PIC identifiers, the full interface name is xe-0/1/7 (assuming a 10GbE transceiver is installed). Understanding this physical-to-logical mapping is essential for accurate cabling and configuration within the Junos OS, ensuring that administrators apply the correct logical unit and protocol settings to the intended physical hardware.

質問 # 44
What are two characteristics of IPv6 addressing? (Choose two.)
正解：B、D
解説：
IPv6 introduces several fundamental shifts in networking architecture compared to its predecessor, IPv4. The most prominent characteristic is the address length; IPv6 utilizes a 128-bit address space, represented in hexadecimal notation across eight groups of 16 bits. This massive expansion from IPv4 ' s 32-bit limit was designed to ensure long-term address availability for the global internet and the growing ecosystem of connected devices.
Another defining characteristic of IPv6 is the concept of address scope, particularly regarding link-local addresses . Any IPv6 address beginning with the fe80::/10 prefix is classified as link-local. These addresses are automatically configured on every IPv6-enabled interface and are strictly not routable beyond the local physical or logical link segment. They are essential for local link operations such as neighbor discovery and routing protocol adjacency formation.
Architecturally, IPv6 also improves performance by streamlining the packet header. Unlike IPv4, the IPv6 header does not include a checksum, as modern link-layer (Layer 2) and transport-layer (Layer 4) protocols perform their own error checking, making a redundant header checksum unnecessary at the network layer.
Additionally, IPv6 replaces the broadcast-based Address Resolution Protocol (ARP) with the multicast-based Neighbor Discovery Protocol (NDP). Understanding these core traits-massive address length and non- routable link-local scoping-is critical for managing modern Junos-based network infrastructures.

質問 # 45
Click the Exhibit button.
Referring the exhibit, what does the highlighted number indicate?
正解：C
解説：
In the exhibit shown, the highlighted number next to the route type (Static) within the square brackets indicates the route preference, also known as the administrative distance. In Junos, the route preference is a value that determines the priority of the route source. Lower numbers indicate a higher priority when the routing table is being calculated. The route preference is used to select the best route when multiple paths to the same destination exist from different routing sources. The number 5 is unusually low for a static route by default, suggesting it has been manually configured to override other route types.
