NEW QUESTION # 119
Which two statements are correct about BGP local preference? (Choose two.)
Answer: B,C
Explanation:
Local preference is a well-known, discretionary BGP path attribute carried exclusively in IBGP UPDATE messages, and Junos assigns every route a local preference value of 100 by default whenever a route is received without an explicit LOCAL_PREF value already attached, or when the attribute has not been otherwise modified through routing policy. This default of 100 becomes the implicit baseline against which any administrator-configured local preference adjustments are compared. Because higher local preference values are always preferred over lower ones during BGP best-path selection -- and this evaluation happens before AS path length, origin, or MED are ever considered -- network engineers commonly use local preference specifically to steer outbound traffic leaving the autonomous system toward a preferred exit peer or upstream provider, by assigning a higher local preference to routes learned from that preferred peer relative to routes learned from alternative peers, making the third statement correct as well. Local preference is explicitly excluded from advertisement to EBGP peers under the BGP specification; it is meaningful only within the boundaries of a single AS and is stripped before a route crosses an AS boundary outward, since a neighboring AS has no reason to trust or honor another organization's internal preference values. A local preference of 0 does not have any special 'drop' semantics in BGP -- it is simply the lowest possible numeric preference value and is treated like any other value during comparison, not as a discard instruction.
NEW QUESTION # 120
Which two statements are true about the default VLAN on Juniper switches? (Choose two.)
Answer: C,D
Explanation:
On Juniper switches, the default VLAN is set to a VLAN ID of 1 by default. This means that all interfaces on the switch are members of VLAN until they are specifically assigned to another VLAN. Therefore, option A is correct.
The default VLAN ID can be changed. This allows network administrators to configure the switch to use a different VLAN as the default, if necessary. Therefore, option D is correct.
NEW QUESTION # 121
Which statement describes the additional overhead added when a packet is encapsulated in a GRE tunnel?
Answer: A
Explanation:
A GRE-encapsulated packet consists of the original passenger packet wrapped inside a GRE header and a new outer IP delivery header, and the combined size of these two additions is what constitutes GRE's per-packet overhead. The base GRE header, as defined in RFC 2784 and used in its minimal, non-keyed, non-checksummed form (the default and most common deployment), is exactly 4 bytes in length, containing the flags/version field and the protocol type field identifying the encapsulated payload's ether type. Layered around that GRE header is a completely new outer IPv4 header, which itself consumes a standard 20 bytes, containing the tunnel source and destination addresses used for delivery across the underlying network. Adding these two components together -- 4 bytes for the GRE header plus 20 bytes for the new outer IPv4 header -- yields a total of exactly 24 bytes of overhead imposed on every encapsulated packet, which is precisely why Junos automatically sets the default protocol MTU on gr- tunnel interfaces to 1476 bytes (1500 minus 24) to prevent oversized, post-encapsulation packets from requiring fragmentation on a standard 1500-byte Ethernet path. The 20-byte figure alone describes only the new IP header in isolation and omits the GRE header itself, while 12 and 32 bytes do not correspond to any standard, non-keyed GRE encapsulation configuration and are included purely as plausible-looking distractors.
NEW QUESTION # 122
You want to redistribute the static routes into BGP, but they do not show as BGP routes.
What causes this result to occur?
Answer: D
NEW QUESTION # 123
What determines the preferred route to a destination in an IS-IS network?
Answer: A
Explanation:
IS-IS is a link-state protocol that, like OSPF, runs Dijkstra's Shortest Path First algorithm independently on each router against its own copy of the synchronized link-state database to compute the best path toward every reachable destination. Each link within the topology carries an administrator-assigned or default metric, and as the SPF algorithm walks the topology graph from the local router outward, it sums the metrics of every link traversed along a candidate path to produce that path's total accumulated cost. Among all possible paths to a given destination prefix, IS-IS always selects and installs the path (or, in the case of equal-cost multipath, the set of paths) with the numerically lowest total accumulated metric, exactly mirroring the 'lowest cost wins' principle shared by essentially all link-state IGPs. A higher accumulated metric value is by definition a less preferred, more costly path, making that option the direct inverse of correct IS-IS behavior. Level 2 proximity to the destination has no independent bearing on path selection beyond however it happens to be reflected in the accumulated metric itself - IS-IS does not apply a separate rule preferring paths merely for passing near a Level 2 router. Likewise, LSP recency (sequence number or freshness) governs which version of a given LSP is trusted and flooded during database synchronization, ensuring the topology database itself is accurate and loop-free, but it plays no role in the SPF cost comparison once the database is synchronized and consistent. Reference topics: Junos Enterprise Routing - IS-IS, SPF Calculation and Metric-Based Path Selection.
