NEW QUESTION # 150
You are required to ensure that Switch 1 will always be designated as the root bridge when participating in your switched network.
What do you need to do to satisfy this requirement?
Answer: C
Explanation:
Because root bridge election is decided primarily by comparing bridge priority values - with the switch advertising the numerically lowest priority always winning, and MAC address serving only as a fallback tiebreaker when priorities are tied - the only deterministic, reliable way to guarantee that a specific switch is elected root regardless of any other switch's hardware characteristics is to explicitly configure that switch with a lower bridge priority than every other participating switch in the topology. Relying on MAC address alone, as the first distractor suggests, is fundamentally unreliable: MAC addresses are burned in at the factory, cannot be predicted or controlled by the administrator, and any future hardware replacement or newly introduced switch with a numerically lower MAC address could unexpectedly seize the root role since MAC comparison only comes into play at equal priority in the first place, meaning a 'highest MAC' strategy does not even align with how the tiebreak actually favors the lowest value. Port priority and port cost are entirely separate STP parameters that influence which port on a non-root switch is selected as its root port, or which port is selected as designated versus blocking on a given segment; neither parameter has any bearing whatsoever on which switch is elected root bridge for the whole topology, since that decision is made purely from the Bridge ID comparison, independent of any per-port settings. Explicitly and deliberately lowering Switch 1's configured bridge priority is the only correct, industry-standard method.

NEW QUESTION # 151
You deployed a new EX Series switch with DHCP snooping enabled and you do not see any entries in the snooping databases for an interface. Which two Juniper configurations for that interface caused this issue? (Choose two.)
Answer: B,C
Explanation:
A is correct because the interface is configured as a disabled port. A disabled port does not forward any traffic, including DHCP packets. Therefore, DHCP snooping cannot learn any MAC addresses or lease information from a disabled port.
C is correct because the interface is configured as a trunk port. By default, all trunk ports on the switch are trusted for DHCP snooping. This means that DHCP snooping does not inspect or filter any DHCP packets received on a trunk port. Therefore, DHCP snooping does not add any entries to the snooping database for a trunk port.
NEW QUESTION # 152
Two routers share the same highest priority and start time. In this situation, what is evaluated next when determining the designated router?
Answer: A
Explanation:
According to the OSPF protocol, the designated router (DR) is the router that acts as the focal point for exchanging routing information on a multi-access network segment, such as a LAN. The DR election process is based on the following criteria, in order of precedence:
The router with the highest OSPF priority becomes the DR. The default priority is 1, and a priority of 0 means the router will not participate in the election.
If there is a tie in priority, the router with the highest router ID becomes the DR. The router ID is a
32-bit number that uniquely identifies a router in an OSPF domain. It can be manually configured or automatically derived from the highest IP address of a loopback interface or a physical interface. If there is a tie in router ID, the router that was first to become an OSPF neighbor becomes the DR. In your scenario, two routers share the same highest priority and start time.
This means that they have equal chances of becoming the DR based on the first and third criteria. Therefore, the second criterion will be used to break the tie, which is the router ID. The router with the highest router ID will become the DR, and the other router will become the backup designated router (BDR), which is ready to take over the role of DR if it fails.
NEW QUESTION # 153
Two Juniper Networks EX Series Switches are connected with four 1-GbE links configured as a single link aggregation group (LAG). One of the physical member links experiences a failure. By default, what impact will this failure have on traffic forwarding between the switches?
Answer: C
Explanation:
A link aggregation group bundles multiple physical Ethernet links into a single logical interface (an ae interface) specifically to provide both increased aggregate bandwidth and link-level redundancy. By default, the aeX interface remains operationally up as long as at least one member link within the bundle remains active and passing traffic; the LAG does not require every member link to be functional to continue operating. When one of the four 1-GbE member links in this scenario fails, LACP (if in use) or the underlying link-status monitoring detects the failure, removes that specific link from the active forwarding set, and redistributes traffic hashing across the three remaining healthy member links automatically and without operator intervention. End devices and upper-layer protocols continue to see a single, continuously up ae interface throughout this process, experiencing only a proportional reduction in available aggregate bandwidth rather than any interruption in connectivity. This default behavior is precisely why LAG is a foundational building block for resilient EX Series switch interconnects in enterprise and data center designs, since it allows individual optic, cable, or transceiver failures to be absorbed transparently. None of the distractor behaviors -- full administrative shutdown of the bundle, forwarding limited to broadcast traffic only, or a temporary disabling of all member links during renegotiation -- reflect actual Junos LAG behavior, which is designed explicitly to avoid any such disruption.
NEW QUESTION # 154
Which statement is correct about how a Juniper Networks EX Series Switch learns MAC addresses?
Answer: B
Explanation:
Layer 2 MAC learning on an EX Series switch, as on any standard Ethernet bridge, is a passive, frame- driven process rather than an active polling or query-based mechanism. Every time a frame arrives on any interface, the switch inspects the frame's source MAC address field and, if that address is not already present in the Ethernet switching (bridge) table for the associated VLAN, creates a new dynamic entry recording the source MAC address, the VLAN it was learned on, and the specific ingress interface through which the frame arrived. Junos also stamps each learned entry with an aging timestamp, which is refreshed every time a subsequent frame from that same source MAC is received; entries that receive no refreshing traffic within the configured MAC aging interval (300 seconds by default) are eventually purged from the table to keep it current and to reclaim table space from hosts that have moved or gone offline. This source- address-driven, per-frame learning process happens continuously and automatically with no dependency on spanning-tree state changes -- although a topology change notification can trigger accelerated aging of the table to flush potentially stale entries faster, learning itself is not gated by or contingent upon such an event occurring. The switch never learns addresses from the destination field of a frame, since the destination address, if already known, is used purely for the forwarding lookup decision, not for populating new table entries.
