質問 # 45
You are using tunnels in your network. It is important that the routes be specific enough to ensure that the tunnels are established. You need to prevent a route that is new to the network from being used. In this scenario, which type of route should be used?
正解：D
質問 # 46
You are asked to change the setting for the LSAs age out back to the default value. In this scenario, which time interval will accomplish this task?
正解：A
質問 # 47
Which two statements about MACsec are true? (Choose two.)
正解：A、C
質問 # 48 
Click the Exhibit button.
You are asked to ensure that there will not be any unwanted STP topology changes affecting your root bridge placement because a rogue switch was introduced into the network at the access layer.
Referring to the exhibit, which interfaces will need to have root protection applied to accomplish this task?
正解：B
解説：
Root protection (root guard) must always be applied on the ports of the switches you trust to remain root- bridge-eligible, specifically on the interfaces facing away from the legitimate root and toward parts of the network where an untrusted or rogue device could plausibly appear and begin transmitting superior BPDUs.
In this topology, Switch-1 is the intended, permanent root bridge (lowest priority, 4k), and Switch-2 is its aggregation-layer peer; both sit above the access layer, where Switch-3 and Switch-4 connect downstream toward end-user-facing infrastructure and where an accidental or malicious rogue switch is realistically most likely to be introduced. The ge-0/0/6 and ge-0/0/8 interfaces on Switch-1 and Switch-2 are precisely the downlink ports facing that access layer, meaning they are the exact points at which a rogue switch's superior BPDU (one advertising a lower priority than the legitimate root) would first be received if such a device appeared beneath Switch-3 or Switch-4. Applying root protection on those specific interfaces causes Junos to immediately block (move to a root-inconsistent, discarding state) any port that receives a superior BPDU, preventing the rogue device from ever being accepted as root, while normal, non-superior BPDUs continue to be processed without disruption. Applying root guard on Switch-1 and Switch-2's peer link (ge-0/0/12/13) would be inappropriate, since that link legitimately connects two trusted, root-eligible switches.

質問 # 49
What is the purpose of the native VLAN feature on the Juniper Networks EX Series Switches?
正解：B
解説：
A native VLAN is a trunk-port concept, not an access-port concept. On an 802.1Q trunk, every frame is normally expected to carry a VLAN tag identifying its membership; the native VLAN is the single exception that Junos permits an administrator to define using the native-vlan-id statement under the trunk interface's family ethernet-switching hierarchy. Any untagged frame arriving on that trunk port is automatically classified into the configured native VLAN, and conversely, outbound frames belonging to the native VLAN are transmitted untagged rather than with an 802.1Q header. This behavior exists chiefly for interoperability with legacy or third-party devices that either cannot generate 802.1Q tags or intentionally send management or default traffic untagged across an otherwise tagged trunk. Access ports, by definition, only ever carry a single VLAN's traffic and never receive tagged frames in normal operation, so the native VLAN mechanism has no relevance there - which eliminates the access-port-oriented answer choices. The native VLAN also does not restrict a trunk to a single VLAN; the trunk continues to carry all configured tagged VLANs simultaneously, with the native VLAN simply being the designated untagged exception. Misconfiguring or mismatching native VLAN IDs between two trunk peers is a classic Layer 2 troubleshooting scenario on the exam. Reference topics: Junos Enterprise Switching - VLANs, Configuring the Native VLAN on a Trunk Interface.
