質問 # 31
What are two fiber-optic connector types? (Choose two.)
正解：B、D
解説：
Physical layer connectivity for Junos devices involves a variety of media types, with fiber-optic cabling being the standard for high-speed, long-distance, or high-density uplink requirements. Two of the most prevalent connector types used in these environments are the LC (Lucent Connector) and the SC (Subscriber Connector) .
The LC connector is a small-form-factor (SFF) connector that uses a 1.25 mm ferrule. Due to its compact size and " push-and-latch " mechanism, it is the primary connector type found on SFP, SFP+, and XFP transceivers used in Juniper EX, MX, and QFX series hardware. Its high-density design allows for more ports in a limited space on a line card or chassis. The SC connector , often referred to as a " square connector, " utilizes a larger 2.5 mm ferrule and a " push-pull " snapping mechanism. While it was highly common in older legacy hardware and fiber patch panels, it has largely been superseded by the LC in modern data center and enterprise switching environments.
In contrast, the RJ-45 is a standard copper Ethernet connector (typically used with Category 5e/6 cables), and the BNC (Bayonet Neill-Concelman) is a miniature quick connect/disconnect RF connector used for coaxial cable. As a Senior Architect, distinguishing between these physical interfaces is critical when specifying the correct Small Form-factor Pluggable (SFP) modules and patch cables required to bring a Junos interface into an operational up/up state.

質問 # 32
Which two statements are true about the firewall filter configuration shown in the exhibit? (Choose two.)
正解：A、B
解説：
The exhibit illustrates the configuration of a firewall filter named mgmt_fill and its subsequent application to an interface. The first true statement is that the filter is applied to a physical interface . The configuration shows the filter attached to me0 , which in Junos nomenclature represents the Management Ethernet port-a dedicated physical port for out-of-band management traffic. This is separate from logical or virtual interfaces, as me0 provides the physical link for administrative access.
The second true statement is that the filter evaluates SSH packets egressing from the management interface . In the provided snippet, term t1 specifically matches the destination-port ssh , and the filter is applied to the interface unit. When a filter is applied to an interface, it can monitor traffic entering or leaving the device. Furthermore, the filter utilizes a count action (count c1), which is a non-terminating action used to provide telemetry on specific traffic types passing through that physical port. There is no mention of a syslog or log action in the configuration, meaning that while packets are counted, they are not being written to the system log files. This configuration is a standard method for hardening the management plane and tracking administrative session activity on the Routing Engine.

質問 # 33
Which Junos OS component is responsible for maintaining the forwarding table?
正解：C
解説：
The Routing Engine (RE) is responsible for maintaining the routing table and the forwarding table.
It runs the routing protocols, computes the best paths, and updates the routing table accordingly.
The routing table information is then used to populate the forwarding table, which is provided to the Packet Forwarding Engine (PFE) to make packet-forwarding decisions.
質問 # 34
Which two statements about firewall filters are correct? (Choose two.)
正解：A、D
解説：
Firewall filters in Junos OS are stateless, meaning they process each packet individually without regard to the state of a connection or sequence of packets. These filters can match various packet attributes, including those at Layer 4, such as TCP and UDP port numbers. This allows for granular control over traffic based on the type of service or application. Unlike stateless filters, stateful firewalls keep track of the state of active connections and make decisions based on the context of the traffic flow, which is not a capability of Junos firewall filters. Additionally, Junos firewall filters primarily operate up to Layer 4 and do not natively inspect Layer 7 parameters, which involve application-level data.
質問 # 35
Which two characteristics apply to TCP? (Choose two.)
正解：C、D
解説：
Comprehensive and Detailed 150 to 250 words of Explanation From: The Transmission Control Protocol (TCP) is a core transport-layer protocol within the TCP/IP suite designed to provide a highly reliable, connection-oriented service. Unlike the User Datagram Protocol (UDP), which is connectionless and best- effort, TCP ensures that data is delivered accurately and in the correct order. A defining characteristic of TCP is its use of a three-way handshake to establish a session. This process involves the exchange of SYN, SYN- ACK, and ACK segments, which synchronizes sequence numbers between the two endpoints and ensures both hosts are ready for data transfer.
Furthermore, TCP provides reliable, ordered delivery by utilizing sequence numbers and acknowledgments. Each data segment is assigned a sequence number; the receiving host uses these numbers to reassemble the data in its original order, even if segments arrive out of sequence due to network jitter or multiple paths. If a segment is lost, the lack of a timely acknowledgment triggers a retransmission, guaranteeing that the application receives all data. TCP does not provide fixed latency guarantees, as its error- recovery mechanisms can introduce delays. Additionally, TCP is a unicast-only protocol and does not support broadcasting on Ethernet.

UDP.
