質問 # 76
Which three actions are required to implement filter-based forwarding? (Choose three.)
正解:A、B、D
解説:
Filter-Based Forwarding (FBF) in Junos OS allows traffic to be routed based on specific criteria such as source address, rather than just the destination address. This is useful in scenarios like policy routing or providing multiple paths for different types of traffic.
Step-by-Step Breakdown:
Instance-Type Forwarding:
You must create an instance-type forwarding routing instance. This routing instance allows for different routing tables based on the incoming packet filter.
Command:
set routing-instances FBF-instance instance-type forwarding
Match Filter:
You need to create a filter to match the traffic that will be forwarded according to your custom routing policy. This filter is applied to an interface to determine which traffic will use the custom forwarding instance.
Command Example:
set firewall family inet filter FBF-filter term 1 from source-address <address> set firewall family inet filter FBF-filter term 1 then routing-instance FBF-instance RIB Group:
A RIB (Routing Information Base) group is necessary to share routes between the primary routing table and the custom routing instance. This allows FBF traffic to use the routing information from other routing tables.
Command Example:
set routing-options rib-groups FBF-group import-rib inet.0
set routing-instances FBF-instance routing-options rib-group FBF-group
Juniper Reference:
FBF Configuration: Filter-based forwarding requires these specific steps to redirect traffic to a custom routing table based on filter criteria.
質問 # 77
In the Junos OS, which feature is used to create an alternate next hop with a unique preference for a static route?
正解:B
解説:
In Junos OS, the qualified-next-hop feature is used to specify an alternate next hop for a static route, along with a unique preference value.
Step-by-Step Breakdown:
Qualified-Next-Hop:
A qualified-next-hop allows you to define multiple next hops for a static route, each with its own preference. This provides flexibility by allowing the router to choose the best available next hop based on reachability and preference.
Use Case:
If the primary next hop becomes unreachable, the router can automatically switch to the alternate next hop defined by the qualified-next-hop with a higher preference value.
Command Example:
set routing-options static route 10.10.10.0/24 qualified-next-hop 192.168.1.1 preference 5 set routing-options static route 10.10.10.0/24 qualified-next-hop 192.168.1.2 preference 10 Preference:
The next hop with the lowest preference is chosen first. If it becomes unavailable, the router will use the higher preference next hop.
Juniper Reference:
Qualified-Next-Hop: This feature is used to configure backup or alternate next hops for static routes in Juniper devices.
質問 # 78
MACsec provides protection against which two types of threats? (Choose two.)
正解:B、D
解説:
MACsec (Media Access Control Security) provides data confidentiality, integrity, and origin authenticity at Layer 2, protecting against several types of threats.
Step-by-Step Breakdown:
Man-in-the-Middle Attack Protection:
MACsec encrypts traffic at Layer 2, preventing man-in-the-middle attacks where an attacker intercepts and manipulates traffic between two communicating devices. Since the data is encrypted, any intercepted packets are unreadable.
Protection Against Playback Attacks:
MACsec also protects against playback attacks by using sequence numbers and timestamps to ensure that old, replayed packets are not accepted by the receiver. Juniper Reference: MACsec Configuration: Juniper devices support MACsec for securing Layer 2 communications, ensuring protection against replay and man-in-the-middle attacks in sensitive environments.
質問 # 79
Referring to the exhibit, why are the BGP routes hidden?
正解:D
解説:
In the exhibit, the BGP routes are marked as hidden. This typically happens when the routes are not considered valid for use, but they remain in the routing table for reference. One common reason for BGP routes being hidden is that the next hop for these routes is unreachable.
Step-by-Step Breakdown:
BGP Next Hop:
In BGP, when a route is received from a neighbor, the next hop is the IP address that must be reachable for the route to be used. If the next hop is unreachable (i.e., the router cannot find a path to the next-hop IP), the route is marked as hidden. Analyzing the Exhibit:
The exhibit shows that the BGP next hop for all hidden routes is 10.4.4.4. If this IP is unreachable, the BGP routes from that neighbor will not be considered valid, even though they appear in the routing table.
Verification:
Use the command show route 10.4.4.4 to check if the next-hop IP is reachable.
If the next-hop is not reachable, the BGP routes will be hidden. Resolving the next-hop reachability issue (e.g., fixing an IGP route or an interface) will allow the BGP routes to become active. Juniper Reference: Junos Command: show route hidden displays routes that are not considered for forwarding. Troubleshooting: Check the next hop reachability for hidden BGP routes using show route <next-hop>.
