Juniper JN0-694 問題集

質問 1：
-- Exhibit --
policy-options {
policy-statement accept-static {
from protocol static;
then accept;
}
}
-- Exhibit --
Click the Exhibit button.
The policy shown in the exhibit is deployed on a router and used as the only BGP export policy. The router is sending only one BGP route to its peers. However, when you run the CLI command test policy accept-static 0.0.0.0/0, the policy matches thousands of routes.
Which statement explains this discrepancy?
A. The default policy for the test policy command is to accept all routes.
B. The default policy for BGP is to reject all routes.
C. The test policy command always shows all routes, regardless of whether they match the policy, when you use the 0.0.0.0/0 argument.
D. All policies have an implicit then accept final term.
正解：A

質問 2：
You are implementing Q-in-Q tunneling on an EX Series switch. You want the tunnel to
support all C-VLANs; however, only some VLANs are able to send traffic across the tunnel. Switch-1 has the following configuration:
[edit vlans]
user@Switch-1# show
v100 {
vlan-id 100;
interface {
ge-0/0/0.10;
ge-0/0/1.20;
}
dot1q-tunneling {
customer-vlans [ ];
}
}
What would solve this problem?
A. Implement RSTP.
B. Q-in-Q tunneling will not work in this scenario; use a Layer 2 VPN instead.
C. Remove the customer-vlans statement.
D. Add family ethernet-switching to the tunnel-side interface on Switch-1.
正解：B

質問 3：
You add a multicast source to a network. The source's DR sends register messages to the
RP However, multicast clients are not able to receive traffic from the source. What are two causes of this problem? (Choose two.)
A. A reject policy is configured on the designated router.
B. The designated router must send a null register message to the RP.
C. The RP did not receive a PIM join message for the group specified.
D. A reject policy is configured on the RP.
正解：C,D

質問 4：
You use static routes for connectivity to the ISP. Your ISP recently switched to using different links for multicast and unicast traffic. Following the change, users in your company were unable to receive multicast traffic through the ISP.
What must you configure on your router to reestablish multicast connectivity to your ISP?
A. Add a static default route to the ISP in the inet.2 routing table.
B. Add the default-rpf-interface parameter under the [edit routing-options multicast] hierarchy.
C. Add the upstream-interface parameter under the [edit protocols pim] hierarchy.
D. Disable PIM on the interface used for unicast traffic.
正解：A

You are sending traffic to the ge-0/0/0 interface on R1 with the expedited forwarding (101) IP precedence bits. However, the counters on the router show that it is not processing any traffic in the expedited forwarding queue.
Referring to the exhibit, what is causing the problem?
A. The classifier is assigning the traffic to the best-effort forwarding class.
B. The classifier is dropping the traffic.
C. The classifier does not contain a mapping for this precedence value.
D. The classifier is assigning the traffic a high loss priority.
正解：A
