질문 # 181
Which two statements are correct about VRRP? (Choose two.)
정답：B,D
설명：
The virtual IP address must match on all participating devices - All routers in the same VRRP group must be configured with the same virtual IP address to provide redundancy.
The VRRP group number must match on all participating devices - All routers in the same VRRP group must have the same group number to identify the VRRP group.
질문 # 182
You implemented the MAC address limit feature with the shutdown action on all interfaces on your switch.
In this scenario, which statement is correct when a violation occurs?
정답：A
설명：
When the MAC address limit feature with the shutdown action is implemented on a switch, if a violation occurs, the interface is disabled and a system log entry is generated. If the switch has been configured with the port-error-disable statement, the disabled interface recovers automatically upon expiration of the specified disable timeout. However, if the switch has not been configured for auto-recovery from port error disabled conditions, you must manually clear the violation by running the clear ethernet-switching port-error command for the interface to send and receive traffic again. This explanation is based on the Enterprise Routing and Switching Specialist (JNCIS-ENT) documents and learning resources available at Juniper Networks.
질문 # 183
How would you view the metric assigned to a route in OSPF? (Choose two.)
정답：B,D
설명：
The metric that OSPF assigns to a destination is visible from two complementary vantage points in Junos. The show route protocol ospf command displays the main routing table filtered to OSPF-learned prefixes, and each entry shows the computed cost alongside the next hop, exactly as it was installed after SPF calculation.
The show ospf route command (which accepts filters such as intra-area, inter-area, and extern) presents the OSPF-specific routing table, organized by route type, and explicitly lists the metric column for every intra- area, inter-area, and external route the local router has calculated. Together these two commands give both the RIB-level and the protocol-level view of route cost. By contrast, show ospf database extensive dumps the raw link-state advertisements, where metrics appear only as link-level values buried inside Router or Network LSAs rather than as a resolved route cost, so it is not the direct tool for viewing a route's metric. show ospf interface reports interface operational state, area, and DR/BDR information but does not present a cost or metric field at all in its standard output. Candidates should be comfortable distinguishing the RIB-oriented and protocol-table-oriented verification commands, since JNCIS-ENT scenarios frequently test whether a candidate reaches for the correct show command layer during troubleshooting.

질문 # 184
Which IS-IS PDU should be used by a router to list all LSPs that it believes should exist in the link-state database?
정답：D
설명：
The Complete Sequence Number PDU (CSNP) is the IS-IS mechanism used to summarize the entire contents of a router's link-state database, listing the LSP ID, sequence number, checksum, and remaining lifetime for every LSP the sending router currently believes should exist in the database for that level. On broadcast (LAN) circuits, the elected Designated Intermediate System periodically transmits CSNPs to all routers on the segment as a database-synchronization mechanism; any receiving router compares the summarized list against its own local database, and any discrepancy -- an LSP it is missing entirely, or one for which it holds an older sequence number -- triggers a targeted request for the specific, updated LSP content. On point-to-point circuits, a single CSNP is exchanged once when the adjacency first comes up, serving the identical synchronization purpose without needing periodic repetition. The Partial Sequence Number PDU (PSNP), by contrast, is used to acknowledge receipt of specific LSPs or to explicitly request specific LSPs identified as missing or outdated after a CSNP comparison, making it a partial, targeted PDU rather than a complete database listing. The LSP itself is the PDU that actually carries the detailed topology and reachability information being advertised, rather than a database summary. The IS-IS Hello PDU (IIH) is used purely for neighbor discovery and adjacency maintenance and carries no link-state database summary information whatsoever.
질문 # 185
Refer to Exhibit:
R1 is not responding to ICMP requests sent to the VIP address.
Referring to the exhibit, which command option would you configure on the virtual address to correct this problem?
정답：B
설명：
In this configuration, R1's physical interface address (10.10.10.1) is different from the VRRP virtual IP address (10.100.100.1), meaning R1 is operating as a non-owner VRRP master - it did not originate the virtual address as one of its own real interface addresses. By default, Junos VRRP masters that do not own the virtual address will forward transit traffic destined through that address but will not process or respond to traffic addressed directly to the VIP itself, such as ICMP echo requests, Telnet, or SSH sessions aimed at
10.100.100.1. This is deliberate default behavior intended to prevent ambiguity about which physical device is answering on behalf of a shared virtual identity. To allow the master to accept and respond to packets whose destination is the virtual address itself, the accept-data statement must be explicitly configured under the vrrp- group hierarchy. Once enabled, the elected master will process locally destined traffic sent to the VIP, resolving exactly the symptom described. The track option is used for interface or route-based priority adjustment to influence mastership, advertise-interval tunes the frequency of VRRP hello advertisements, and no-preempt prevents a higher-priority router from reclaiming mastership once a lower-priority router has taken over - none of these affect whether the master processes traffic destined to the VIP.
