질문 # 122
You are configuring a router as a new Level 1 router in an existing Level 1 area. The NET address for an existing Level 1 router is 49.0011.1111.2222.3333.00. The new router must form a Level 1 adjacency with the existing router. What should be the area ID in this scenario?
정답：B
질문 # 123
Which IS-IS TLV should be used to advertise information about the router's neighbors and link metrics?
정답：D
설명：
TLV 22, the Extended IS Reachability TLV defined in RFC 5305, is the modern and Junos-preferred mechanism for advertising a router's adjacent neighbors together with the metric associated with each link. It carries the seven-octet system ID and pseudonode number of each neighbor along with a 24-bit wide metric field, and supports an extensible set of sub-TLVs used for traffic-engineering data such as interface and neighbor IP addresses, bandwidth, and administrative groups. The original IS Reachability TLV, TLV 2, defined in the base ISO 10589 standard, carries similar neighbor and metric information but is constrained to a 6-bit narrow metric with a maximum value of 63, which is inadequate for expressing meaningful cost differentiation in modern, high-capacity enterprise and service-provider topologies; consequently, Junos deployments are commonly configured for wide-metrics-only, favoring TLV 22 over the legacy TLV 2 whenever traffic-engineering-capable or simply more granular metric representation is desired. TLV 132, the IP Interface Address TLV, only advertises the IPv4 addresses configured on the originating router's interfaces and carries no neighbor-adjacency or metric information. TLV 129, the Protocols Supported TLV, merely lists which network-layer protocols (such as IPv4 or IPv6) the originating router is capable of routing, and likewise has nothing to do with neighbor reachability or link cost.

질문 # 124
Which sequence correctly describes the basic message flow that leads to a successful BGP peering session?
정답：B
설명：
RFC 4271 defines the BGP finite state machine as a strict, ordered progression of six states that a session must move through to successfully establish. A newly configured or reset session always begins in Idle, where BGP initializes resources and refuses connections until the ConnectRetry timer fires. From Idle, the router transitions to Connect and attempts to establish the underlying TCP transport session to the configured peer address on port 179. If that TCP attempt does not immediately succeed, the session falls back to the Active state, where the router continues retrying the TCP connection in the background; once the TCP handshake finally completes (from either Connect or Active), the session advances to OpenSent, during which the router transmits its own BGP OPEN message advertising its AS number, hold time, BGP identifier, and capabilities.
Upon receiving and validating a compatible OPEN message from the peer, the session moves to OpenConfirm, where both sides exchange KEEPALIVE messages to confirm the parameters negotiated in the OPEN exchange are mutually acceptable. Only after this confirmation does the session reach Established, the final state in which UPDATE messages carrying actual routing information begin to flow between the peers.
Any deviation from this Idle # Connect # Active # OpenSent # OpenConfirm # Established ordering, as presented in the other answer choices, does not reflect the standardized BGP state machine. Reference topics:

질문 # 125
You want to configure a floating static route.
What must be configured in this scenario?
정답：D
설명：
A floating static route is a backup static route that remains present in the configuration but stays inactive in the routing table under normal conditions, only becoming active if the primary, preferred route to the same destination is withdrawn or otherwise becomes unavailable. Junos determines which of several competing routes to the same prefix becomes active strictly by comparing each route's preference value (administrative distance), with the numerically lowest preference always winning; every routing protocol and static routes themselves carry a default preference (5 for standard static routes), and this value can be explicitly overridden per route using the preference statement under the static route's configuration. To create a floating static route, the administrator deliberately configures a preference value higher (that is, numerically worse, less preferred) than the preference of the primary route it is meant to back up - for example, a value higher than the 5 default of an ordinary static route, or higher than a dynamic protocol's preference such as OSPF's 10 - ensuring the floating route only becomes active once the more-preferred primary route disappears from the table entirely. This preference-based mechanism is the essential, defining configuration element of a floating static route. Priority is not a valid Junos static-route statement, next-hop simply defines where matching traffic is forwarded without controlling route selection behavior, and qualified-next-hop is a related but distinct mechanism used to assign a per-next-hop preference within a single multi-next-hop static route statement rather than between the standalone static route and its dynamic counterpart. Reference topics: Junos Enterprise Routing - Protocol Independent Routing, Configuring Floating Static Routes with Preference.
질문 # 126
Which two BGP attributes must be supported by all BGP implementations and must be included in every update? (Choose two.)
정답：B,D
설명：
BGP attributes are properties that BGP uses for route advertisement, path selection, and loop prevention. There are four categories of BGP attributes:
Well-known mandatory: Must be recognized by all BGP routers, present in all BGP updates, and passed on to other BGP routers.
Well-known discretionary: Supported by all BGP implementations, and are optionally included in BGP updates.
Optional transitive: May not be supported by all implementations of BGP.
Optional non-transitive: May not be supported by all implementations of BGP. The well-known mandatory attributes must be supported by all BGP implementations and must be included in every update. These include the AS path and next hop attributes.
