A.  

An IP-VRF is a Layer 3 network instance.

B.  

Packets in an IP-VRF are forwarded based on the destination IP address.

The router maintains a distinct route table for each IP-VRF instance.

D.  

Multiple servers can be connected to the same subnet in an IP-VRF.

A.  

Checkpoint 0 is always the oldest checkpoint.

B.  

The current running configuration can be saved as a JSON-formatted checkpoint file.

C.  

The operator can revert to any existing checkpoint.

D.  

The operator can generate a new checkpoint when committing configuration changes.

A.  

It can help rapidly detect link failures.

B.  

The BFD endpoints agree on the send/receive rate of control packets.

C.  

BGP is notified if several BFD control packets are missed.

D.  

Using BFD can speed up the BGP advertisement interval.

A.  

They are forwarded to the destination node based on the MAC VRF table.

B.  

They are forwarded to the destination node based on the MAC VRF table. (Duplicate of A)

C.  

They are periodically flooded to the broadcast MAC address on each interface.

D.  

They are routed to the destination node based on the IP VRF forwarding table.

A.  

The hash value used to distribute traffic is calculated as a modulo function on specific fields of the packet header.

B.  

Hash buckets are used to ensure that flows egressing the same interface on one router use different egress interfaces on downstream routers.

C.  

A different hash seed is used on downstream routers to ensure that flows are randomly distributed across all eligible router interfaces.

D.  

When one of the next-hops fail, only flows currently egressing to that next-hop are impacted.

A.  

An IP address is configured under the IRB’s subinterface.

B.  

An IRB subinterface is configured in an IP-VRF network instance.

C.  

One IRB subinterface is configured for each interface within a MAC-VRF network instance.

D.  

One IRB subinterface is configured in a MAC-VRF network instance.

A.  

Type 1 Ethernet Auto-Discovery (A-D) EVPN route is used to support EVPN multi-homing.

B.  

Type 4 Ethernet Segment (ES) EVPN route is used for designated forwarder (DF) election for an ES.

C.  

The ES identifier (ESI) uniquely identifies an ES and it is locally significant for a particular leaf.

D.  

The Ethernet Segment (ES) identifies a set of links that connects a host to one or more leafs.

A.  

The ZTP process downloads a provisioning script defined in the TLS profile.

B.  

The ZTP process is managed by the ZTP application in Nokia SR Linux.

C.  

The ZTP process relies on a DHCP server for an IP address.

B.  

The system-cpu-policer is hardware-based.

C.  

The system-cpu-policer acts on the aggregate traffic from all line cards.

D.  

CPM-filter entries can use both a distributed-policer and a system-cpu-policer.

A.  

It monitors the health of all applications.

B.  

It manages the SR Linux and customer-defined applications.

C.  

It reads the application’s configuration information and starts each application.

D.  

It translates the application’s YANG model into protobufs for the IDB.
