質問 # 152
You want to enable redundancy for the EBGP peering between the two routers shown in the exhibit.
Which three actions will you perform in this scenario? (Choose three.)
正解：A、B、C
解説：
A is correct because you need to configure BGP multihop to enable redundancy for the EBGP peering between the two routers. BGP multihop is a feature that allows BGP peers to establish a session over multiple hops, instead of requiring them to be directly connected. By default, EBGP peers use a time-to-live (TTL) value of 1 for their packets, which means that they can only reach adjacent neighbors. However, if you configure BGP multihop with a higher TTL value, you can allow EBGP peers to communicate over multiple routers in between. This can provide redundancy in case of a link failure or a router failure between the EBGP peers.
B is correct because you need to configure loopback interface peering to enable redundancy for the EBGP peering between the two routers. Loopback interface peering is a technique that uses loopback interfaces as the source and destination addresses for BGP sessions, instead of physical interfaces. Loopback interfaces are virtual interfaces that are always up and reachable as long as the router is operational. By using loopback interface peering, you can avoid the dependency on a single physical interface or link for the BGP session, and use multiple paths to reach the loopback address of the peer. This can provide redundancy and load balancing for the EBGP peering.
C is correct because you need to configure routes for the peer loopback interface IP addresses to enable redundancy for the EBGP peering between the two routers. Routes for the peer loopback interface IP addresses are necessary to ensure that the routers can reach each other's loopback addresses over multiple hops. You can use static routes or dynamic routing protocols to advertise and learn the routes for the peer loopback interface IP addresses. Without these routes, the routers will not be able to establish or maintain the BGP session using their loopback interfaces.
質問 # 153
You need to configure a LAG between your switches. In this scenario, which two statements are correct?
(Choose two.)
正解：B、D
解説：
B is correct because duplex and speed settings are required to match on both participating devices. According to the Juniper Networks documentation1, all the interfaces in a LAG must have the same speed and be in full-duplex mode. This ensures that the LAG can operate as a single logical link without any performance or compatibility issues.
C is correct because member links are not required to be contiguous ports. According to the Juniper Networks documentation2, you can group any Ethernet interfaces on a switch into a LAG, regardless of their physical location or slot number. This provides flexibility and scalability for configuring LAGs on switches.
質問 # 154
Exhibit
Referring to the exhibit, which two configuration changes must you apply for packets to reach from R1 to R3 using IS-IS? (Choose two.)
正解：A、B
解説：
Explanation
A: On R1, enable Level 1 on the ge-0/0/1 interface. In IS-IS, both levels (Level 1 and Level 2) are enabled by default when you enable IS-IS on an interface1. Level 1 systems route within an area2. If the destination is outside an area, Level 1 systems route toward a Level 2 system2. Therefore, enabling Level 1 on the ge-0/0/1 interface on R1 would allow packets to reach from R1 to R3.
D: On R3 enable Level 1 on the ge-0/0/4 interface Similarly, enabling Level 1 on the ge-0/0/4 interface on R3 would allow packets to reach from R1 to R3.
These explanations are based on the IS-IS configuration documents and learning resources available at Juniper Networks1 and Cisco34.
質問 # 155
Click the Exhibit button.
Which two statements about the firewall filter terms shown in the exhibit are true? (Choose two.)
正解：B、C
解説：
A firewall filter is a Junos security solution to filter or control traffic at the data plane as they enter or exit an interface 1 . A firewall filter consists of one or more terms, each with a set of conditions and actions 2 . The device evaluates every packet against the firewall filter terms in the order they are defined, and performs the actions specified in the first term that matches the packet 3 . If no term matches the packet, the device discards the packet by default 3 .
In the exhibit, the firewall filter mac-address is applied to the family ethernet-switching and involves filtering MAC addresses. There are two terms, term one and term two , each with different conditions and actions. The from statement specifies the match conditions, and the then statement specifies the actions. If the from statement is omitted, all packets are considered to match and the actions in the then statement are taken 2 . If the then statement is omitted, the packets that match the conditions in the from statement are accepted by default 2 .
* Term one logs traffic from a specific source MAC address 88:05:00:29:3c:de/48 . The log action is a nonterminating action, which means that the device continues to evaluate the packet against the remaining terms in the filter 2 . Therefore, traffic that matches the from statement in term one is not discarded, and option A is incorrect.
* Term two accepts all other traffic not specified in term one. The then accept action is a terminating action, which means that the device stops evaluating the packet against the filter and forwards the packet 2 . Therefore, all traffic not matching the from statement in term one is accepted by term two, and option D is correct.
* Term two does not have a from statement, which means that all packets are considered to match this term. Therefore, traffic matching the from statement in term two is not logged, and option B is incorrect.
* Term one does not have a then statement other than the log action, which means that the packets that match the from statement are accepted by default. Therefore, traffic that matches the from statement in term one is accepted, and option C is correct.
