질문 # 14
Which two fields must match in an OSPF hello packet to form an adjacency over a broadcast link? (Choose two.)
정답：A,C
설명：
RFC 2328 specifies a precise set of parameters that two OSPF routers on a broadcast network must agree upon before a valid neighbor relationship can be established, and a mismatch in any of these mandatory fields causes the routers to reject each other's Hello packets outright rather than forming even a basic 2-Way state. The network mask carried in each Hello packet must match between neighbors on a broadcast segment, since OSPF uses this field to confirm both routers agree on the subnet boundaries of the shared segment; a mismatched mask (for example, one router configured with a /24 and its neighbor with a /25 on the same physical wire) is treated as a configuration error and blocks adjacency formation. The router dead interval, which defines how long a router will wait without receiving a Hello before declaring a neighbor down, must likewise match exactly between neighbors, alongside the closely related hello interval, since these timers govern the shared expectations both sides have for how frequently Hellos should arrive and how quickly a failure should be detected; Junos explicitly checks and rejects Hello packets carrying a mismatched dead interval value. Router priority, by contrast, is intentionally allowed to differ between neighbors on the same segment -- it exists precisely so that administrators can differentiate router preference for the DR/BDR election, and differing values are expected and normal rather than being blocked. The designated router field, as advertised within each Hello, is informational about the sender's current view of the segment's DR and is not a value that must be identical between the two Hello senders to permit adjacency formation.
질문 # 15
Which two statements describe OSPF DR and BDR behavior? (Choose two.)
정답：C,D
설명：
The Backup Designated Router exists specifically to provide immediate failover redundancy for the Designated Router role on a multi-access broadcast or NBMA segment: the BDR maintains full adjacencies with every other router on the segment concurrently with the DR, precisely so that if the DR ever fails or is withdrawn, the BDR can be promoted directly to DR essentially instantaneously, without needing to wait through a fresh, full DR/BDR election process, and a new BDR election then takes place separately among the remaining DROther routers to fill the now-vacant backup role. This immediate promotion behavior confirms the first statement as correct. The Designated Router's other core responsibility on the segment is originating the Type
2 Network LSA, which describes the multi-access network itself as a pseudonode, listing every router attached to that segment; this LSA type exists specifically to avoid the full-mesh explosion of Router LSA adjacency listings that would otherwise be needed to describe a shared broadcast segment, and only the DR -- never the BDR, and never any DROther -- is responsible for generating and maintaining this particular LSA under normal, stable conditions, which confirms the third statement while directly ruling out the fourth. There is no such thing as the DR 'electing' an area border router; ABR status is instead a role a router acquires organically by having interfaces in more than one OSPF area, entirely independent of any DR/BDR election process on any individual segment.
질문 # 16
A host connected to interface ge-0/0/3 on your Juniper Networks EX Series Switch cannot reach another device in the same VLAN. The administrator wants to confirm that the switch has learned the MAC address of the host. Which command should be used to accomplish this task?
정답：D
설명：
The show ethernet-switching table command displays the Layer 2 forwarding database (the bridge or MAC table) that an EX Series switch builds dynamically by inspecting the source MAC address of every frame it receives. Each entry records the learned MAC address, the VLAN it was learned on, the type of entry (dynamic, static, or persistent), and the specific interface through which that address was seen, which is precisely the information needed to confirm whether the switch has learned the host connected to ge-0/0/3. If the host's MAC address is absent from the table, that immediately points to a Layer 1/2 issue -- no frames have been received from the host, a cabling or port problem exists, or the interface is administratively down or blocked by spanning tree -- rather than a Layer 3 routing or VLAN membership problem. show interfaces terse only reports administrative and link state along with any assigned protocol family addresses, offering no MAC-learning visibility. show vlans lists VLAN definitions and their member interfaces but does not display learned host addresses. show interfaces extensive provides detailed physical-layer counters and error statistics, useful for diagnosing frame loss or interface errors, but it does not expose the switching table. For intra-VLAN reachability troubleshooting, verifying MAC learning is always the first and most direct Layer 2 checkpoint.
질문 # 17
A recent security audit indicates that peer-to-peer applications are allowed on the guest VLAN and employees may have been using the guest VLAN for this purpose. You deploy the configuration shown in the exhibit, but it does not stop the peer-to-peer traffic.
In this scenario, what must you do to implement the security policy?
정답：D
질문 # 18
