質問 # 56
Which two statements are correct about tunnels? (Choose two.)
正解：B、D
解説：
For a tunnel to be established, the endpoints must have a route to each other. This is essential for the encapsulated packets to reach their destination.
Tunnels encapsulate packets, adding extra headers for the encapsulation protocol, which increases the overall packet size.
質問 # 57
Your company has a branch location that uses a Juniper Networks EX Series Switch. You are asked to troubleshoot a spanning-tree issue that keeps reoccurring within the branch environment. After investigation, you discover that end-devices running a virtualization application are generating BPDUs, which are disrupting the spanning-tree topology and causing periodic outages. Which solution will prevent this problem from reoccurring?
正解：C
解説：
This scenario describes end hosts -- virtualization hosts running software switches or virtual bridging stacks -- unexpectedly generating and transmitting BPDUs on ports that are supposed to be pure edge (host-facing) ports where no BPDUs should ever legitimately be received. BPDU protection (BPDU guard) is the Junos feature purpose-built for exactly this situation: when applied to an edge- designated interface, it continuously monitors that port for any incoming BPDU, and the moment one is detected, it immediately and automatically disables the port, preventing the unexpected BPDU source from ever participating in or influencing the spanning-tree topology calculation, thereby protecting the stable, intended topology from disruption caused by unauthorized or accidental BPDU generation at the access edge. This directly and precisely resolves the described problem at its source, since the root cause is illegitimate BPDUs arriving on ports that were never meant to see them. Increasing the max-age timer only adjusts how long stale topology information is retained before being aged out and has no effect on preventing rogue BPDUs from being processed in the first place. Disabling RSTP outright on access interfaces would eliminate spanning tree's loop- prevention protection on those ports entirely, introducing a much more severe risk of undetected Layer 2 loops. Root protection (root guard) defends specifically against a port attempting to become the root port by receiving a superior BPDU claiming a better path to root; it addresses a different threat model than blocking any BPDU outright on a true edge port.
質問 # 58
Which two statements are correct about using firewall filters on EX Series switches? (Choose two.)
正解：A、C
解説：
A is correct because you can deploy only stateless firewall filters on an EX Series switch. A stateless firewall filter is a filter that evaluates each packet individually based on the header information, such as source and destination addresses, protocol, and port numbers. A stateless firewall filter does not keep track of the state or context of a packet flow, such as the sequence number, flags, or session information. EX Series switches support only stateless firewall filters, which are also called access control lists (ACLs) or packet filters.
C is correct because you can apply firewall filters to both Layer 2 and Layer 3 traffic on an EX Series switch. Layer 2 traffic is traffic that is switched within a VLAN or a bridge domain, while Layer 3 traffic is traffic that is routed between VLANs or networks. EX Series switches support three types of firewall filters: port (Layer 2) firewall filters, VLAN firewall filters, and router (Layer
3) firewall filters. You can apply these filters to different interfaces and directions to control the traffic entering or exiting the switch.
質問 # 59
In a LAN segment, which tie-breaker would spanning tree consider if equal-cost paths exist between two or more switches to the root bridge?
正解：D
質問 # 60
A Juniper Networks EX Series Switch has storm control enabled on all interfaces. The ge-0/0/1 interface carrying several VLANs hits its storm control limit and is shut down. In this scenario, which command allows you to manually clear the violation?
正解：D
解説：
When storm control on an EX Series switch is configured with an action of interface-shutdown (rather than the default of simply dropping excess traffic), exceeding the configured bandwidth threshold for broadcast, multicast, or unknown-unicast traffic causes Junos to administratively disable the offending interface to protect the rest of the switching fabric. Recovery from this condition can happen automatically if a recovery-timeout interval has been configured, but when immediate manual recovery is required, the operational command clear ethernet-switching recovery-timeout interface interface-name explicitly clears the storm-control-triggered violation and re-enables the port without waiting for the timer to expire. This command is purpose-built for this exact condition and is distinct from more general troubleshooting commands: clear ethernet- switching table purges the learned MAC address database and has no bearing on a storm- control-disabled port; clear interface statistics resets traffic counters for diagnostic baselining but does not touch administrative state; and clear log messages simply flushes the local system log buffer. Administrators should also verify the underlying cause of the storm -- a switching loop, a misbehaving host, or a misconfigured device -- before manually clearing the condition, since without addressing the root cause the port is likely to trip again. This command and workflow are commonly tested as part of the Layer 2 security and resiliency features on EX platforms.
