문제2

Which statement is correct about CoS policers on Junos devices?

A. A policer can assign in-profile traffic to a specific forwarding class.

B. A policer does not alter in-profile traffic.

C. Policers can be configured to buffer traffic that exceeds the policer's traffic profile.

D. Traffic that exceeds a policer's traffic profile can be dropped or assigned to a specific drop profile.

정답: D

문제3

You are designing a multicast topology to support IPv4 IPTV broadcasts in your organization. The design should support multiple multicast senders with overlapping group addresses while preventing interference between them. Client devices currently do not support IGMPv3.
Which approach would fulfill these requirements?

A. Implement bidirectional PIM

B. Implement PIM-SM and SSM with SSM maps to support IGMPv2 clients

C. Assign group addresses in the 224/4 range and implement PIM-DM

D. Implement MLD

정답: C

문제4

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?

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

B. Disable the BPDU block function on the distribution switch.

C. Disable the BPDU block function on the access switches.

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

C. Policers reduce the speed of an interface.

D. Policers do not reduce the speed of an interface.

정답: A,D

문제6

Referring to the exhibit, which two statements are true? (Choose two)

A. There is no need for a DR for the ge-0/0/0 interface.

B. There can be more than one OSPF neighbor on the ge-0/0/0 interface

C. The DR election process is not finished for the ge-0/0/0 interface

D. There can be more than one OSPF neighbor on the ge-0/0/1 interface.

정답: A

문제7

You are troubleshooting an EVPN-VXLAN IP fabric and observe the loop shown in the exhibit.
Which two steps would you take to further troubleshoot this problem? (Choose two.)

A. Verify that the same ESI is configured on the two links from the source.

B. Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.

C. Verify that the same ESI is configured on the link from the host and that it matches the source.

D. Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.

정답: B,D
