EMT Practice Test

1. Question Content...

---

Question1: A routing table contains multiple BGP routes to the same destination prefix. The route preference is the same for each route.

Referring to the exhibit, which route would be selected?

Question2: You are enabling dynamic ARP inspection on an EX4300 switch.
Which service is enabled by default in this scenario?

Question3: Which statement is true when using LAGs with an EX4300?

Question4: What are the three possible port states when using RSTP? (Choose three.)

Question5: You manage a Layer 2 network that spans two buildings. You are asked to ensure that all traffic that traverses this connection between the two buildings is secured.
Which port security feature should be used to secure this Layer 2 traffic?

Question6: Click the Exhibit button. Referring to the exhibit, which policy will export routes to IBGP peers?

Question7: Given the route shown in the exhibit, which two prefixes contribute to the aggregate route?
(Choose two.)

Question8: Which two statements are true about DIS elections in IS-IS? (Choose two.)

Question9: What are three extended BGP communities? (Choose three.)

Question10: What are two OSPF packet types that use multicast for communication on a multicast segment?
(Choose two.)

Question11: 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?

Question12: 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?

Question13: Referring to the exhibit, which three statements are true? (Choose three.)

Question14: You have configured OSPF routing as shown in the exhibit. You notice that all interfaces have formed full adjacencies, with the exception of the interfaces connecting R3 and R4 with a status of 2Way.

What is the reason for this status?

Question15: You are adding a new EX4300 member switch to your existing EX4300 Virtual Chassis. However, the new member is not running the same Junos version as the other members.
By default, what is the expected behavior?

Question16: You want to configure Layer 2 services over an IP-based tunneling mechanism between two sites. Which configuration statement is required to accomplish this task?

Question17: Which two statements are true about the IRB interface? (Choose two.)

Question18: 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?

Question19: 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?

Question20: Which statement is true about Layer 2 firewall filters on EX Series switches?

Question21: You are adding a new EX4300 member switch to your existing EX4300 Virtual Chassis. However, the new member is not running the same Junos version as the other members. By default, what is the expected behavior in this scenario?

Question22: You have an existing Virtual Chassis consisting of five member devices. Member 3 fails and must be replaced. You remove the EX Series switch with a Member ID of 3 and install a replacement switch in its place using identical cabling as shown in the exhibit. The replacement's member ID is 6, so the configuration for member ID 3 is not applied to it.

Referring to the exhibit, what should have been done before installing the replacement switch?

Question23: Referring to the exhibit, which configuration change is needed for an IS-IS Level 1 adjacency between R1 and R2?

Question24: Referring to the output shown in the exhibit, which statement is correct?

Question25: Click the Exhibit button. Given the configuration shown in the exhibit, what will be the threshold for storm control?

Question26: Which three statements are true regarding not-so-stubby areas (NSSAs)? (Choose three.)

Question27: Which three mechanisms are associated with the bridging process? (Choose three.)

Question28: You disconnected a switch from the Virtual Chassis, but the disconnected switch's member ID is still displayed in the status output.
Which operational command is used to remove the disconnected member?

Question29: Which two port security features use the DHCP snooping database for additional port security?
(Choose two.)

Question30: Your router is configured to peer with your ISP's router using BGP. You can only control your BGP configuration.

Which address families are negotiated between the two BGP peers shown in the exhibit?

Question31: What are two terminating actions of a Layer 2 firewall filter? (Choose two.)

Question32: Click the Exhibit button. The exhibit shows that Host-1 and Host-2 are attached to the switch and associated with IRB irb.1.
However, traffic sent from Host-1 to Host-2 is not blocked as expected.
Why is this problem occurring?

Question33: Click the Exhibit button. Switch-1 in the exhibit receives a packet from User A with a destination MAC address of 00:26:88:02:74:48. Which statement is correct?

Question34: Which two sequences correctly describe the processing order of firewall filters on an EX Series switch? (Choose two.)

Question35: Both the R1 and R2 devices are advertising prefix X into AS 65530 with the BGP attributes shown in the exhibit.

Which statement is correct in this scenario?

Question36: Referring to the exhibit, what is the problem?

Question37: Referring to the exhibit, which statement explains why the route to 192.168.178.0/24 advertised from 192.168.35.90 is hidden?

Question38: Which two statements about DHCP snooping are correct? (Choose two.)

Question39: You are troubleshooting your OSPF configuration and notice that you have subnet mismatch errors when running the show ospf statistics command.
Which two actions would further troubleshoot the errors? (Choose two.)

Question40: Which two OSPF header fields must match to form an adjacency over a broadcast connection?
(Choose two.)
