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?
  1. 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.
  2. Prepend the AS path to all routes received from ISP A while all routes received from ISP B use the default AS path value.
  3. 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.
  4. 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?
  1. You must enable the voice VLAN feature on the incoming interfaces and assign the v20 VLAN.
  2. You must enable an IRB interface and assign it to the v10 and v20 VLANs.
  3. You must enable LLDP-MED on the incoming interfaces and assign the v20 VLAN.
  4. 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.)
  1. The AS Path contains a 0.
  2. It is suppressed by a damping policy.
  3. The Local Preference is 0.
  4. The next hop is unreachable.
  5. 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?
  1. set vlans default switch-options interface-mac-limit 4 
  2. set vlans default switch-options interface-mac-limit 5
  3. set switch-options interface ge-0/0/23.0 interface-mac-limit 3
  4. clear ethernet-switching recovery-timeout interface ge-0/0/23.0
Correct answer: C
Question 5
Which two statements are true regarding RIB groups? (Choose two.)
  1. The first table listed is the primary route table and determines the address family of the RIB group.
  2. The last table listed is the primary route table and determines the address family of the RIB group.
  3. A RIB group must contain one or more export-rib statements.
  4. A RIB group must contain one or more import-rib statements.
Correct answer: AD
Question 6
By default, how long will a learned MAC address be retained in the bridge table on an EX Series switch?
  1. 600 seconds
  2. 3600 seconds 
  3. 300 seconds
  4. 1800 seconds
Correct answer: C
Question 7
  
Referring to the exhibit, which interface is assigned the active VIP?
  1. Router A ge-0/0/2
  2. Router B ge-0/0/1
  3. Router A ge-0/0/1 
  4. Router B ge-0/0/2
Correct answer: B
Question 8
  
Referring to the exhibit, which devices will receive the packet sent by User B?
  1. User A and User D
  2. User C and User D
  3. User C
  4. User C, User A, and User D 
Correct answer: B
Question 9
Your router is learning the 172.25.11.0/24 prefix from both the BGP and OSPF protocols. A routing policy is configured on your device to advertise the prefix to an established BGP peer but the peer is not receiving the prefix. You want to allow the prefix to be advertised to the BGP peer. 
What should you do on this router to satisfy this requirement?
  1. Enable the automatic removal of peer AS information from the prefix.
  2. Enable the advertisement of inactive BGP routes.
  3. Enable the automatic removal of private AS numbers from the prefix.
  4. Enable the automatic refreshing of BGP routes.
Correct answer: B
Question 10
What is a characteristic of OSPF ASBRs?
  1. ASBRs transmit routing information between the backbone and other areas.
  2. ASBRs cannot be part of the backbone and another area at the same time.
  3. ASBRs inject routing information from outside the OSPF domain.
  4. ASBRs link two OSPF areas.
