NEW QUESTION # 108
Exhibit:
Referring to the exhibit, which two statements are correct about default BGP advertisements? (Choose two.)
Answer: C,D
Explanation:
The exhibit shows a BGP peering scenario between three routers: router1 and router2 are part of the same AS (AS65000), while the SP router is in a different AS (AS65101). This indicates an EBGP (External BGP) peering between the SP router and router1, and IBGP between router1 and router2.
Step-by-Step Breakdown:
Next-Hop Behavior in BGP:
IBGP: In IBGP, the next-hop address is not modified when advertising routes within the same AS. Thus, when router1 advertises routes learned from router2 to the SP router, it will keep the next-hop address of router1, not router2.
EBGP: In EBGP, the next-hop address is modified. When router1 receives routes from the SP router, it will advertise them to router2 with the next-hop address of router1.
Route Propagation:
Routes received by router1 from router2 will be advertised to the SP router with router1 as the next hop.
Similarly, routes advertised by the SP router will be passed on to router2, with router1 remaining as the next hop.
Juniper
Reference: BGP Next-Hop: Juniper's BGP implementations follow standard BGP next-hop behavior, where the next-hop is modified in EBGP but not in IBGP, ensuring proper route advertisement across autonomous systems.
NEW QUESTION # 109
VLANs help in reducing which of the following? (Choose two)
Answer: C,D
NEW QUESTION # 110
What is the primary purpose of an IRB Layer 3 interface?
Answer: A
Explanation:
The primary purpose of an IRB (Integrated Routing and Bridging) interface is to enable inter-VLAN routing in a Layer 3 environment. An IRB interface in Junos combines the functionality of both Layer 2 bridging (switching) and Layer 3 routing, allowing devices in different VLANs to communicate with each other.
Step-by-Step Breakdown:
VLANs and Layer 2 Switching:
Devices within the same VLAN can communicate directly through Layer 2 switching. However, communication between devices in different VLANs requires Layer 3 routing.
IRB Interface for Inter-VLAN Routing:
The IRB interface provides a Layer 3 gateway for each VLAN, enabling routing between VLANs. Without an IRB interface, devices in different VLANs would not be able to communicate.
Configuration:
In Juniper devices, the IRB interface is configured by assigning Layer 3 IP addresses to it. These IP addresses serve as the default gateway for devices in different VLANs. Example configuration:
set interfaces irb unit 0 family inet address 192.168.1.1/24 set vlans vlan-10 l3-interface irb.0 This allows VLAN 10 to use the IRB interface for routing.
Juniper
Reference: IRB Use Case: Inter-VLAN routing is essential in data centers where multiple VLANs are deployed, and Juniper's EX and QFX series switches support IRB configurations for this purpose.
NEW QUESTION # 111
Exhibit:
Referring to the exhibit, which next hop will be preferred in the routing table?
Answer: D
Explanation:
In the exhibit, we see a static route configuration with two possible next hops for the default route (0.0.0.0/0):
next-hop 172.25.20.254 with the default preference of 7.
qualified-next-hop 172.25.20.200 with a preference of 6.
Step-by-Step Breakdown:
Preference Value:
In Junos OS, the preference value is used to determine which route should be preferred in the routing table. The lower the preference value, the higher the priority for the route.
Comparison:
In this case:
The next hop 172.25.20.254 has a preference of 7.
The qualified-next-hop 172.25.20.200 has a preference of 6.
Preferred Next Hop:
Since 172.25.20.200 has a lower preference (6) compared to 172.25.20.254 (7), it will be the preferred next hop in the routing table, assuming both next hops are reachable.
Juniper Reference:
Qualified Next Hop: In Junos, static routes with multiple next-hop options are selected based on the preference value, with the lower value being preferred.
NEW QUESTION # 112
What are two device roles in a five-member Virtual Chassis? (Choose two.)
Answer: B,C
Explanation:
In a Virtual Chassis (VC) configuration, multiple Juniper switches are interconnected to form a single logical device. Each member switch in the Virtual Chassis plays a specific role.
Step-by-Step Breakdown:
Line Card Role:
Member switches acting as line cards provide additional ports for traffic forwarding but do not perform control or routing functions. These switches depend on the routing engine to handle control-plane tasks.
Routing Engine Role:
A switch in the routing-engine role is responsible for control-plane operations such as routing protocol management and control of the Virtual Chassis.
Virtual Chassis Roles:
Master Routing Engine: Handles control-plane functions and manages the entire Virtual Chassis.
Backup Routing Engine: Takes over if the master fails.
Line Card: Provides additional ports and handles data-plane operations.
Juniper Reference:
Virtual Chassis: In a five-member Virtual Chassis, multiple switches act as line cards, while one or more switches are designated as the routing engines (master and backup).
