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
  
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 4
  
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 5
What are three requirements to ensure proper GRE or IP-IP tunnel routing? (Choose three.)
  1. Keepalives must be used on stateless tunneling protocols.
  2. Tunnel endpoints must have a route that directs traffic into the tunnel.
  3. BGP must be used on intermediate devices.
  4. Tunnel endpoints must have a valid route to the remote endpoint.
  5. All intermediary devices must have a route to the tunnel endpoints.
Correct answer: BCD
Question 6
You are configuring IBGP and you must ensure that reachability is maintained between participating routers, even if the physical topology changes. 
Which two actions should you perform in this scenario? (Choose two.)
  1. Configure DHCP on all IBGP devices.
  2. Configure an IGP within your IBGP network.
  3. Configure static routes to all IBGP peers.
  4. Configure IBGP peerings to loopback addresses.
Correct answer: BD
Question 7
What is the default route preference for BGP?
  1. 150
  2. 167
  3. 170
  4. 179
Correct answer: C
Question 8
  
Which statement is true about the configuration shown in the exhibit?
  1. Only the next-hop-self export policy will be evaluated when routes are sent to neighbor 172.30.1.1.
  2. Both the adv-aggregate and adv-custom export policies will be evaluated when routes are sent to neighbor 172.30.2.1.
  3. Both the adv-aggregate and next-hop-self export policies will be evaluated when routes are sent to neighbor 172.30.1.1.
  4. Only the adv-custom export policy will be evaluated when routes are sent to neighbor 172.30.2.1.
Correct answer: D
Question 9
  
You are configuring IS-IS on the newly provisioned ae88 interface. After you commit the configuration, you notice that your adjacency is not showing up. 
Referring to the exhibit, what is the reason for the adjacency being down?
  1. R1 and R2 are configured for different metrics.
  2. R1 and R2 are in different IS-IS levels. 
  3. R1 and R2 have different interface parameters.
  4. R1 and R2 are configured for different areas.
Correct answer: C
Question 10
  
Referring to the exhibit, which set of interfaces is enabled for Ethernet switching?
  1. ge-0/0/6, ge-0/0/7, and ge-0/0/8
  2. ge-0/0/6, ge-0/0/8, and ge-0/0/10
  3. ge0/0/6, ge-0/0/7, ge-0/0/8, and ge-0/0/10
  4. ge-0/0/6 and ge-0/0/8
Correct answer: C
