NEW QUESTION # 46
Your enterprise network uses routing instances to support multitenancy. Your Junos devices use BGP to peer to multiple BGP devices. You must ensure that load balancing is achieved within the routing instance.
Which two statements would accomplish this task? (Choose two.)
- A. Configure the multipath option at the [edit protocols bgp group <group-name> neighbor] hierarchy.
- B. Configure the multipath option at the [edit protocols bgp group] hierarchy.
- C. Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding-table] hierarchy.
- D. Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.
Answer: B,C
Explanation:
Fortunately, the Juniper Networks BGP implementation supports the notion of a bandwidth community. This extended community encodes the bandwidth of a given next hop, and when combined with multipath, the load-balancing algorithm distributes flows across the set of next hops proportional to their relative bandwidths. Put another way, if you have a 10-Mbps and a 1-Mbps next hop, on average nine flows will map to the high-speed next hop for every one that uses the low speed.
Use of BGP bandwidth community is supported only with per-packet load balancing.
The configuration task has two parts:
Configure the external BGP (EBGP) peering sessions, enable multipath, and define an import policy to tag routes with a bandwidth community that reflects link speed.
Enable per-packet (really per-flow) load balancing for optimal distribution of traffic.

NEW QUESTION # 47
Your network is configured for EVPN load balancing on three different access switches During an outage, you notice that not all interfaces are receiving traffic as expected Which two requirements would you validate to identify this problem? (Choose two )
- A. Validate that the all-active flag configured for multiple interfaces on each switch
- B. Validate that the same esi value is only configured on one interface per switch
- C. Validate that the same esi value is configured on multiple interfaces on all switches.
- D. Validate that all-active is configured for only interface per switch
Answer: A,D
NEW QUESTION # 48
Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series devices? (Choose two.)
- A. Type 1 route advertisements always have the single-active flag set to 0.
- B. Junos OS supports underlay replication for BUM traffic forwarding.
- C. Junos OS supports ingress replication for BUM traffic forwarding.
- D. Type 1 route advertisements always have the single-active flag set to 1.
Answer: A,C
Explanation:
BUM Traffic Forwarding
Junos devices that use MPLS encapsulation for EVPNs can only use ingress replication at this time.
Ingress replication means, to flood traffic to remote PE routers, the traffic has to be replicated, once for each remote PE router.
The EVPN label for this BUM traffic is learned per PE router from the route type 3, inclusive multicast Ethernet tag route.
This table shows the format of the inclusive multicast Ethernet tag route.
All-Active Redundancy (4)
This diagram shows the format of the type 1 route, A-D route per ES. The split horizon label is advertised as part of an extended community attached to the type 1 route. The split horizon label is also called the ESI label. The extended community also indicates what type of redundancy mode is used for this given ESI: single-active represented by binary 1 or active-active represented by binary 0.
NEW QUESTION # 49
Which three MSTP parameters must match on all switches in the same MST region? (Choose three.)
- A. revision number
- B. MSTI-to-VLAN mapping
- C. configuration name

- E. forwarding delay
Answer: A,B,C

NEW QUESTION # 50
You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?
- A. stub area
- B. totally stubby area
- C. totally non-to-stubby area
- D. non-to-stubby area
Answer: B
Explanation:
A totally stubby area (TSA) is a stub area in which summary link-state advertisement (type 3 LSAs) are not sent. A default summary LSA, with a prefix of 0.0. 0.0/0 is originated into the stub area by an ABR, so that devices in the area can forward all traffic for which a specific route is not known, via ABR.
NEW QUESTION # 51
You are asked to establish interface level authentication for users connecting to your network. You must ensure that only corporate devices, identified by MAC addresses, are allowed to connect and authenticate. Authentication must be handled by a centralized server to increase scalability.
Which authentication method would satisfy this requirement?
- A. 802.1X with multiple supplicant mode
- B. 802.1X with single-secure supplicant mode
- C. MAC RADIUS
- D. captive portal
Answer: C
Explanation:
https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topic-map/mac-radius-authentication-switching-devices.html You can configure MAC RADIUS authentication on an interface that also allows 802.1X authentication, or you can configure either authentication method alone.
If both MAC RADIUS and 802.1X authentication are enabled on the interface, the switch first sends the host three EAPoL requests to the host. If there is no response from the host, the switch sends the host's MAC address to the RADIUS server to check whether it is a permitted MAC address. If the MAC address is configured as permitted on the RADIUS server, the RADIUS server sends a message to the switch that the MAC address is a permitted address, and the switch opens LAN access to the nonresponsive host on the interface to which it is connected.
NEW QUESTION # 52
You are asked to deploy 802.1X on your EX Series switches. You need to ensure authenticated devices continue to have access to the network even if the authentication server fails.
Which action meets this configuration objective?
- A. Set the reauthentication interval to a value of 0.
- B. Configure the server fail fallback with a value of sustain.
- C. Set the reauthentication interval to a value of disable.
- D. Configure the static MAC bypass for the authentication server.
Answer: B
