Question2: -- Exhibit -

-- Exhibit --
Click the Exhibit button.
In the exhibit, Host2 is the only host currently joining group 231.1.1.1, but S1 is still flooding the traffic to all hosts on VLAN 100.
What feature can be configured on S1 to limit the multicast flooding of traffic to only interested hosts on VLAN 100?

Question3: -- Exhibit -

-- Exhibit --
Click the Exhibit button.
Referring to the exhibit, USER1 wants to only receive multicast traffic for group 225.0.0.1 and USER2 wants to only receive multicast traffic for group 225.0.0.2. Both users are connected to an EX Series switch and are receiving unwanted multicast traffic.
What will resolve the problem?

Question4: -- Exhibit -

-- Exhibit --
Click the Exhibit button.
In the exhibit, the 10.100/16 prefix is introduced at autonomous system 1 (AS1) and propagated through to AS3. Router A in AS3 receives two different paths to these prefixes, one through AS2 and the other through AS4. No BGP attributes have been altered.
Which path would router A prefer for the 10.100/16 prefix?

Referring to the exhibit, you are attempting to configure L2PT for VLAN v200 but the configuration will not commit.
Which three configuration statements would resolve the problem? (Choose three.)

Question6: You want to control bursts of HTTP traffic entering your SRX Series Gateway. To support varying requirements, interfaces ge-0/0/0 through ge-0/0/3 should each be rate-limited separately, using the same parameters.
What is the correct way to meet these requirements?

The configuration in the exhibit shows incoming traffic with specific IP precedence bits that should be mapped to a forwarding class named best-effort.
What must you add to complete this configuration?

Question8: -- Exhibit -

-- Exhibit --
Click the Exhibit button.
In the exhibit, Switch A is an EX4200. VLAN10 is receiving tagged as well as untagged traffic from different ports. The administrator wants to mirror all tagged and untagged traffic entering VLAN10 to analyzer port ge-0/0/10. All VLAN tags must be preserved for traffic that is mirrored to the analyzer port.
Which configuration will achieve this?

Question9: You have a requirement for a device to provide 20 W of power over Ethernet.
What meets this requirement?

Looking at the traceoptions output in the exhibit, why are the OSPF routers stuck in Init state?

Question11: R1 and R2 are ASBRs in the same area, each with an equal cost external path to the same external network prefix. R1 advertises an external route into OSPF with a Type 1 metric. R2 advertises an external route into OSPF with a Type 2 metric.
Which route would be preferred?

Question12: You are asked to configure an interface policer. You must ensure when the bandwidth limit and burst size are exceeded, that the packet receives a CoS parameter which increases the probability that the packet will be dropped if the queues are congested.
Which policer action will accomplish this requirement?

You are configuring an EBGP peer in a transit environment. You must advertise routes learned from other EBGP peers in your AS. Any routes originated from within your AS should have a MED of 7000 set. Any routes that originate in AS65222 should be prepended four times. Any routes that transit AS701 should have a MED set to 6. This scenario results in the unintended advertisement of internal 10.0.0.0/8 networks to your peer.
What caused the accidental advertisement of internal networks to your EBGP peer?
