JN0-694 Online Practice Questions and Answers

Questions 4

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. Add family ethernet-switching to the tunnel-side interface on Switch-1.

B. Implement RSTP.

C. Q-in-Q tunneling will not work in this scenario; use a Layer 2 VPN instead.

D. Remove the customer-vlans statement.

-- Exhibit -Click the Exhibit button.

Referring to the exhibit, you are configuring an OSPF network. All OSPF adjacencies come up and stay stable. But neither R1 nor R2 has the prefix 200.200.200.200/32 in its routing table.

What is causing this problem?

A. R2 does not have the export policy for prefix 200.200.200.200/32.

B. R1 does not have routes to network 172.10.1.0/24.

C. R2 is BDR on both network 172.10.1.0/24 and 172.20.1.0/24.

D. The router ID of R1 is the same as the router ID of R3.

-- 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. All policies have an implicit then accept final term.

B. The default policy for BGP is to reject all routes.

C. The default policy for the test policy command is to accept all routes.

D. 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.

Questions 11

There is a lot of traffic marked with IP precedence values af2l and af3l that ingresses the router. The af3l traffic should be using the expedited forwarding queue, but the traffic is much lower than expected and there are no drops seen on the egress interface.

Referring to the exhibit, what is causing the problem?

A. The assured forwarding queue has a strict high priority and is starving the expedited forwarding queue.

B. The expedited forwarding queue has a low priority value; therefore the traffic is not serviced.

C. The MF classifier is forwarding most of the af3l traffic to the best-effort queue.

D. The MF classifier is does not match on af3l and therefore the traffic is being dropped.
