NEW QUESTION # 150
What is the maximum allowable MTU size for a default GRE tunnel without IPv4 traffic fragmentation?
Answer: C
Explanation:
The maximum allowable MTU size for a default GRE tunnel without IPv4 traffic fragmentation is
1476 bytes. This is because GRE packets are formed by the addition of the original packets and the required GRE headers. These headers are 24-bytes in length and since these headers are added to the original frame, depending on the original size of the packet we may run into IP MTU problems. The most common IP MTU is 1500-bytes in length (Ethernet). When the tunnel is created, it deducts the 24-bytes it needs to encapsulate the passenger protocols and that is the IP MTU it will use. For example, if we are forming a tunnel over FastEthernet (IP MTU 1500) the IOS calculates the IP MTU on the tunnel as: 1500-bytes from Ethernet-24-bytes for the GRE encapsulation = 1476-Bytes.
NEW QUESTION # 151
What does the * indicate in the output shown in the exhibit?
Answer: D
Explanation:
The exhibit shows the output of the command show vlans brief, which displays brief information about VLANs and their associated interfaces.
The output has four columns: Routing instance, VLAN name, Interfaces, and Tagging. The * symbol indicates that the interface is active, meaning that it is up and forwarding traffic. This can be verified by the command show interfaces terse, which displays the status of the interfaces.
NEW QUESTION # 152
Referring to the exhibit, which two statements about BGP prefixes advertised by R1 to AS 65501 are true? (Choose two.)
Answer: A,D
NEW QUESTION # 153
You are configuring a GRE tunnel between Router A (192.168.1.1) and Router B (192.168.2.1) to connect two isolated networks. The tunnel interfaces (gr-0/0/0) need to support IPv4 traffic. In this scenario, which configuration ensures the tunnel endpoints are correctly defined and reachable?
Answer: D
Explanation:
A functioning GRE tunnel interface in Junos requires, at minimum, both a tunnel source address and a tunnel destination address configured together under the tunnel statement of the gr- logical unit, since these two values together define the outer, delivery-layer IP header that will encapsulate every passenger packet sent through the tunnel; the source identifies which of the router's own addresses will originate the encapsulated traffic, and the destination identifies the remote tunnel endpoint the encapsulated traffic must be routed toward across the underlying IP network. The first option correctly supplies both required values in a single, complete statement -- source 192.168.1.1 (Router A's own address) and destination 192.168.2.1 (Router B's address) -- fully defining the tunnel's endpoints and ensuring the encapsulation and route-resolution process can succeed. The fourth option supplies only the destination and omits the source entirely, which is an incomplete configuration; without an explicit source, Junos cannot always reliably determine which local address to use for encapsulation, particularly on multi-address or multi-interface routers, and the tunnel configuration is left non-deterministic or non-functional as shown. The second option enables the IPv6 protocol family on the tunnel's logical unit, which is irrelevant to a scenario explicitly requiring IPv4 passenger traffic support. The third option attempts to assign a family inet address directly using one of the underlying tunnel endpoint addresses, which conflates the tunnel's own transport addressing with logical-unit protocol addressing and does not by itself establish the required source/destination tunnel definition.
NEW QUESTION # 154
Which statement is correct about how a Juniper Networks EX Series Switch learns MAC addresses?
Answer: D
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. Reference topics: Junos Enterprise Switching - Layer 2 Switching Fundamentals, Source MAC Learning and Table Aging.
