Demo Questions
Question 1
Your BGP router receives routes from two upstream ISPs: ISP A and ISP B. In this scenario, which change would you make to prefer routes from ISPA?
- Set the local-preference attribute for all routes received from ISP A to 200 while all routes received from ISP B use the default local-preference value of 100.
- Prepend the AS path to all routes received from ISP A while all routes received from ISP B use the default AS path value.
- Change the MED value for all routes received from ISP A to 1 while all routes from ISP B remain configured with no MED value.
- Set the local-preference attribute for all routes received from ISP A to 50 while all routes received from ISP B use the default local-preference value of 100.
Correct answer: A
Question 2
Each PC and IP phone in your network is connected to a switch using the same port. All incoming data traffic is untagged and belongs to the v10 VLAN, while traffic coming from the IP phones is tagged with a VLAN value of 20 and should belong to the v20 VLAN on your switch.
In this scenario, which statement is correct?
- You must enable the voice VLAN feature on the incoming interfaces and assign the v20 VLAN.
- You must enable an IRB interface and assign it to the v10 and v20 VLANs.
- You must enable LLDP-MED on the incoming interfaces and assign the v20 VLAN.
- You must enable the guest VLAN feature on the incoming interfaces and assign the v20 VLAN.
Correct answer: A
Question 3
What are three reasons a BGP route would be hidden? (Choose three.)
- The AS Path contains a 0.
- It is suppressed by a damping policy.
- The Local Preference is 0.
- The next hop is unreachable.
- It is rejected by a firewall term.
Correct answer: ABD
Question 4
You have an ESXi host that is connected to ge-0/0/23 on a Juniper EX Series switch. You added a new VM that will also use the same ge-0/0/23 interface. Unfortunately, the new VM is not able to reach external devices.
Referring to the exhibit, which command would solve this problem?
- set vlans default switch-options interface-mac-limit 4
- set vlans default switch-options interface-mac-limit 5
- set switch-options interface ge-0/0/23.0 interface-mac-limit 3
- clear ethernet-switching recovery-timeout interface ge-0/0/23.0
Correct answer: C
Question 5
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?
- route A
- route B
- route C
- route D
Correct answer: B
Question 6
Which two statements are true regarding RIB groups? (Choose two.)
- The first table listed is the primary route table and determines the address family of the RIB group.
- The last table listed is the primary route table and determines the address family of the RIB group.
- A RIB group must contain one or more export-rib statements.
- A RIB group must contain one or more import-rib statements.
Correct answer: AD
Question 7
By default, how long will a learned MAC address be retained in the bridge table on an EX Series switch?
- 600 seconds
- 3600 seconds
- 300 seconds
- 1800 seconds
Correct answer: C
Question 8
Referring to the exhibit, which interface is assigned the active VIP?
- Router A ge-0/0/2
- Router B ge-0/0/1
- Router A ge-0/0/1
- Router B ge-0/0/2
Correct answer: B
Question 9
Referring to the exhibit, which devices will receive the packet sent by User B?
- User A and User D
- User C and User D
- User C
- User C, User A, and User D
Correct answer: B
Question 10
If an EX Series switch receives a frame with a known destination MAC address, what is the expected behavior?
- The frame is sent out all ports assigned to the associated VLAN except the ingress port on which the frame was received.
- The frame is sent out all ports assigned to all configured VLANs except the ingress port on which the frame was received.
- The frame is sent out all trunk ports associated with the ingress VLAN regardless of whether a matching MAC address was found in the bridge table.
- The frame is sent out the egress port with a matching destination MAC address within the bridge table associated with the ingress VLAN.
Correct answer: D
