Question1: Click the Exhibit button.

Referring to the exhibit, the local router should have an IS-IS adjacency with a neighboring router, but the adjacency never establishes correctly.
What should you do to solve the problem?

Question2: What are two benefits of 802.3ad link aggregation? (Choose two.)

Question3: Which device is used to separate collision domains?

Question4: Your network is configured with dynamic ARP inspection (DAI) using the default parameters for all the DHCP and ARP related configurations. You just added a new device connected to a trunk port and configured it to obtain an IP address using DHCP.
Which two statements are correct in this scenario? (Choose two.)

Question5: Which statement is true when using LAGs with an EX4300?

Question6: Click the Exhibit button.

Based on the traceoptions output shown in the exhibit, what is the problem with the adjacency?

Question7: You want to configure your Junos device so that routing information from certain prefixes on a neighboring router are ignored.
What should you configure on your device?

Question8: Your network connections to the Internet through two different ISPs using EBGP. You must ensure that ISP1 is the primary path used for all traffic entering your network while using ISP2 as a backup path.
In this scenario, which statement is correct?

Question9: Click the Exhibit button.

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

Question10: Click the Exhibit button.

Referring to the exhibit, what do the asterisks (*) indicate?

Question11: In which two STP states is a port active and a MAC address learned? (Choose two.)

Question12: What is the default BGP group type on a Junos device?

Question13: You are enabling dynamic ARP inspection on an EX4300 switch.
Which service is enabled by default in this scenario?

Question14: Click the Exhibit button.

Referring to the exhibit, what will be the IS-IS adjacency result of the configurations?

Question15: You configured a GRE tunnel that traverses a path using default MTU settings. You want to ensure that packets are not dropped of fragmented.
In this scenario, what is the maximum packet size that would traverse the GRE tunnel?

Question16: Click the Exhibit button.

Referring to the exhibit, which policy will export routes to IBGP peers?

Question17: You have configured the router with an IS-IS interface metric of 2048.
However, the IS-IS interface metric of 63 is being applied for the interface of this router.
What must you do to enable the larger metric value?

Question18: Click the Exhibit button.

A recent security audit indicates that peer-to-peer applications are allowed on the guest VLAN and employees may have been using the guest VLAN for this purpose. You deploy the configuration shown in the exhibit, but it does not stop the peer-to-peer traffic.
In this scenario, what must you do to implement the security policy?

Question19: Which two statements are true about an EX2300 device? (Choose two.)

Question20: Which two statements describe BGP attributes? (Choose two.)

Question21: What are two advantages of a point-to-point OSPF adjacency? (Choose two.)

Question22: How many bytes of overhead are added to a packet traversing a GRE tunnel?

Question23: Which statement about configuring persistent MAC learning is correct?

Question24: Click the Exhibit button.

Referring to the exhibit, which router becomes the OSPF DR when all routers are powered on at the same time?

Question25: Which two characteristics are true for EBGP peerings? (Choose two.)

Question26: Which Junos feature allows you to combine multiple interfaces into a single bundle?

Question27: Click the Exhibit button.

You manage the Layer 2 network shown in the exhibit. You experience a failure on the ge-0/0/0 link between Switch-1 and Switch-2.
Which statement is correct about the expected behavior?

Question28: Which statement is true about IP-IP tunnels?

Question29: Which statement is true about Layer 2 firewall filters on EX Series switches?

Question30: Which two sequences correctly describe the processing order of firewall filters on an EX Series switch? (Choose two.)

Question31: An EBGP session sources its TCP connection from which IP address?

Question32: Click the Exhibit button.

A number of reports from end users indicate that internal and external communications are intermittent and not reliable. You verified the status of the switch ports and have determined that they are up and operational. You also noticed a very high level of link bandwidth utilization on those same ports. The current topology of the affected environment is shown in the exhibit.
What would be the cause of the reported issues?

Question33: Which static route next-hop value indicates that the packet will be silently dropped?
