NEW QUESTION # 37
Which two statements are true about an EX2300 device? (Choose two.)
Answer: A,D
NEW QUESTION # 38
Which two statements are correct about using firewall filters on EX Series switches? (Choose two.)
Answer: A,D
Explanation:
A is correct because you can deploy only stateless firewall filters on an EX Series switch. A stateless firewall filter is a filter that evaluates each packet individually based on the header information, such as source and destination addresses, protocol, and port numbers. A stateless firewall filter does not keep track of the state or context of a packet flow, such as the sequence number, flags, or session information. EX Series switches support only stateless firewall filters, which are also called access control lists (ACLs) or packet filters.
C is correct because you can apply firewall filters to both Layer 2 and Layer 3 traffic on an EX Series switch. Layer 2 traffic is traffic that is switched within a VLAN or a bridge domain, while Layer 3 traffic is traffic that is routed between VLANs or networks. EX Series switches support three types of firewall filters: port (Layer 2) firewall filters, VLAN firewall filters, and router (Layer
3) firewall filters. You can apply these filters to different interfaces and directions to control the traffic entering or exiting the switch.
NEW QUESTION # 39 
Click the Exhibit button.
Referring to the exhibit, all possible firewall filters are configured along the path from Server A to Server B.
In which order will Switch 1 process transmit (Tx) and receive (Rx) firewall filters?
Answer: C
Explanation:
Because Server A resides in VLAN 10 and Server B resides in VLAN 20, traffic between them cannot remain a purely Layer 2 switched flow; it must be routed between the two VLANs, which on Switch 1 means the packet traverses the switch's internal routing engine (via an IRB interface) between the ingress and egress switching stages. Junos processes firewall filters along this path in a strict, layered order that mirrors the packet's actual journey through the device. First, any filter applied at the physical ingress port level (Rx-Port) is evaluated as the frame first arrives on ge-0/0/10. Next, any filter applied to the ingress VLAN (Rx-VLAN, i.
e., VLAN 10) is evaluated as the frame is classified into its source broadcast domain. Because the destination subnet requires routing, the packet is then handed to the routing engine, where any input/ingress routed filter (Rx-Router) applied to the receiving IRB interface is evaluated next, followed by any output/egress routed filter (Tx-Router) applied as the now-routed packet is handed from the routing engine back out toward VLAN
20. Finally, the packet passes through any egress VLAN filter (Tx-VLAN, for VLAN 20) and then the egress physical port filter (Tx-Port) on ge-0/0/20 immediately before transmission to Server B. This complete six- stage sequence - Rx-Port, Rx-VLAN, Rx-Router, Tx-Router, Tx-VLAN, Tx-Port - reflects every filter- evaluation checkpoint a routed, inter-VLAN packet passes through on an EX Series Layer 3 switch.

NEW QUESTION # 40
You are a network operator who wants to add a second ISP connection and remove the default route to the existing ISP You decide to deploy the BGP protocol in the network. What two statements are correct in this scenario? (Choose two.)
Answer: A,B
Explanation:
The rules are as simple as follows:
1. IBGP peers advertise routes received from EBGP peers to other IBGP peers.
2. EBGP peers advertise routes learned from IBGP or EBGP peers to other EBGP peers.

NEW QUESTION # 41
You are using OSPF to advertise the subnets that are used by the Denver and Dallas offices. The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets.
Referring to the exhibit, which two statements are correct? (Choose two.)
Answer: A,C
Explanation:
The routers that are directly connected to the Dallas and Denver subnets are not advertising the connected subnets. This can be resolved by redistributing the connected subnets into OSPF.
Option C suggests to configure and apply a routing policy that redistributes the connected Dallas and Denver subnets. This is correct because redistribution allows routes from one routing protocol to be communicated to another, and in this case, it allows the connected subnets to be advertised through OSPF.
Option D suggests enabling the passive option on the OSPF interfaces that are connected to the Dallas and Denver subnets. This is also correct because in OSPF, a passive interface is an interface that belongs to the OSPF router, but does not send OSPF Hello packets. It's typically used on an interface that you don't want to use for OSPF adjacencies, but you still want to advertise its IP address. Therefore, enabling passive interface can help in advertising the Dallas and Denver subnets.
