Question 20

(0)

You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS. Which well-known BGP community should be assigned to these addresses to accomplish this task?

Question 11

You are implementing the route summarization feature of OSPF.

Which two results do you achieve in this scenario? (Choose two.)

It helps in migrating to future multi-area OSPF network designs.

It reduced the routing table size, enabling devices to store and process less information.

It reduces the impact of topology changes on a device.

It provides optimal routing in the network.

Question 13

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.)

Configure the multipath option at the [edit protocols bgp group <group-name> neighbor] hierarchy.

Configure the multipath option at the [edit protocols bgp group] hierarchy.

Configure a load-balance per-packet policy and apply it at the [edit routing-options forwardingtable] hierarchy.

Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.

Question 14

You are asked to enforce user authentication using a captive portal before users access the corporate network.

Which statement is correct in this scenario?

HTTPS is the default protocol for a captive portal.

A captive portal can be bypassed using an allowlist command containing a device's IP address.

When enabled, a captive portal must be applied to each individual interface.

All Web browser requests are redirected to the captive portal until authentication is successful.

Question 15

Referring to the exhibit, ServerA sends a single IP packet destined to 10.0.0.127.

Which two statements correctly describe the behavior of the resulting outbound VXLAN packets that contain the original packet destined to 10.0.0.127? (Choose two.)

Router E will replicate and send a copy of the received VXLAN packet to router D.

Router C will send a VXLAN packet destined only to router D and router E.

Router D will not replicate and send a copy of the received VXLAN packet to router E.

Router C will send a single VXLAN packet to one remote VTEP.

Question 16

A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network.

Which two statements are correct in this scenario? (Choose two.)

Both the next hops will be used to forward traffic to R2.

A routing policy will be required to forward traffic to both next hops.

The TTL value of 1 is set to limit the scope of the EBGP session.

The ttl statement must be configured to accommodate peering to a loopback address of a directly connected peer.

Question 17

You are asked to troubleshoot voice quality issues on your newly implement VoIP network. You notice that the voice packets are being dropped. You have verified that the packets are correctly marked for expedited forwarding queue.

Referring to the exhibit, what must you configure to solve the problem?

You must configure a multifield classifier to put the VoIP traffic in the correct queue.

You must configure a rewrite rule to ensure that the traffic is scheduled properly in the device.

You must configure a scheduler to allocate bandwidth to the expedited forwarding queue.

You must configure a policer to ensure that the queue is not being starved.

Question 18

Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.

Which action would solve this problem?

Configure the links between the access switches and the distribution switch as a trunk port.

Disable the BPDU block function on the access switches.

Disable the BPDU block function on the distribution switch.

Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.
