質問 # 25
Click the Exhibit button.
Referring to the exhibit, R1 and R2 are advertising the same prefix 203.0.113.0/24 to R3 and R4 over EBGP. R3 and R4 both advertise this prefix to R5.
Which advertisement does R5 choose to install in its routing table?
正解：B
解説：
R3 and R4 both advertise the same prefix into iBGP toward R5, but they assign different local preference values. R3 sets a local preference of 150, while R4 sets a local preference of 200.
Since BGP selects routes with the highest local preference before considering other attributes, R5 chooses the route received from R4 and installs it in its routing table.
質問 # 26
Referring to the exhibit, you have an established RSVP LSP between R1 and R4 when you experience a link failure between R2 and R3.
Which two statements are correct? (Choose two.)
正解：B、D
解説：
Upon a link failure in an RSVP-signaled LSP, the router upstream of the failure (R2) sends a PathTear message upstream to the ingress router (R1), and the router downstream of the failure (R3) sends a ResvTear message downstream to the egress router (R4). These messages signal the failure and initiate tear down of the LSP state in the respective directions.
質問 # 27
Click the Exhibit button. Referring to the exhibit, R1 is advertising prefix 203.0.113.0/24 to R2 over EBGP. R2 is configured to advertise this prefix into IBGP. R3 receives the 203.0.113.0/24 route, however the route is hidden.
Which configuration statement do you need to add to R2 to solve this problem?
正解：C
解説：
R2 is advertising the EBGP-learned route into iBGP without changing the next-hop, so R3 receives the route with a next-hop of 172.16.10.1 (R1). Because that next-hop is not reachable from R3, Junos marks the route as hidden. Setting next-hop self on R2 makes the next-hop reachable (R2), so the route becomes usable on R3.
質問 # 28
You are asked to configure interfaces on Juniper devices to support dual VLAN tags. In this scenario, which two interface statements would accomplish this task? (Choose two.)
正解：A、B
解説：
To supportdual VLAN tagging(often referred to as Q-in-Q or 802.1ad), a Juniper interface must be configured to process more than one 802.1Q header. In Junos OS, this is handled at the physical interface level ([edit interfaces <interface-name>]).
According to Juniper Service Provider documents, two primary configuration statements enable this capability:
* stacked-vlan-tagging (Option D):This is the traditional command used to enable an interface to accept frames with two VLAN tags. When this is enabled, the router expects an outer "service" tag and an inner "customer" tag. This is specifically used in provider edge scenarios where a service provider is tunneling multiple customer VLANs.
* flexible-vlan-tagging (Option A):This is a more modern and versatile command. It allows the interface to support a mix of different encapsulation types across different logical units. For example, with flexible-vlan-tagging, you can have one logical unit (unit 10) doing standard single-tagging and another logical unit (unit 20) doing dual-tagging (vlan-tags outer X inner Y). This is the preferred method on newer hardware (like the MX Series) because it provides the highest level of configuration flexibility.
Vlan-tagging (Option C)only enables the interface to support a single 802.1Q tag, andgigether-options (Option B)contains physical-layer settings like auto-negotiation or flow control, which do not influence VLAN encapsulation. Therefore, A and D are the correct mechanisms for enabling dual-tag support.
質問 # 29
Which IPv6 extension header is used to specify intermediate nodes for a packet's path?
正解：C
解説：
In the IPv6 architecture, the base header is kept at a fixed size of 40 bytes to streamline processing. Any additional features or options are handled byExtension Headers, which are inserted between the IPv6 header and the upper-layer protocol. According to Juniper Networks technical documentation and RFC 8200, when a source node needs to list one or more intermediate nodes to be "visited" on the way to the final destination, it utilizes theRouting extension header (Option B).
The Routing header is functionally similar to the "Source Route" option in IPv4. When a packet contains a Routing header, it is addressed to the first intermediate node listed in the header. That node examines the header, swaps its own address with the next address in the list, and forwards the packet. This process continues until the packet reaches the final destination. This is a foundational component for technologies like Segment Routing over IPv6 (SRv6), where the Routing header (specifically the Segment Routing Header or SRH) is used to steer traffic through a specific set of service instructions or nodes.
To distinguish this from the other options:
* Hop-by-hop options (Option A):These carry information that must be examined byeverynode along the path (such as Router Alert), not just specific intermediate nodes.
* Fragment (Option C):This is used only when the source node needs to fragment a packet that exceeds the path MTU.
* Destination options (Option D):These carry optional information intended specifically for the destination node (or nodes listed in a Routing header), but they do not dictate the path themselves.
