Question No: 391 – (Topic 4)

What is the purpose of the forwarding routing instance type?

  1. to create multiple Layer 3 switches

  2. to create a virtual Layer 2 switch

  3. to forward Layer 3 VPN traffic

  4. to implement filter-based forwarding

Answer: D

Question No: 392 – (Topic 4)

– Exhibit –

{master:0}[edit interfaces] user@switch# show

ge-0/0/6 { unit 0 {

family ethernet-switching { port-mode access;

vlan {

members vlan100;

}

}

}

}

ge-0/0/7 { unit 0 {

family ethernet-switching { port-mode access;

vlan {

members vlan100;

}

}

}

}

{master:0}[edit ethernet-swtiching-options] user@switch#show

secure-access-port { interface ge-0/0/6.0 { mac-limit 1 action drop;

}

vlan 100 {

mac-move-limit 1 action drop;

}

}

– Exhibit –

Referring to the exhibit, what will the mac-move-limit command on ge-0/0/6 do?

  1. Packets will be dropped if the switch detects the same source MAC address on interface ge-0/0/6 and ge-0/0/7.

  2. Packets will be dropped if the switch detects the same source MAC address on two separate interfaces in VLAN 100.

  3. Packets will be dropped and the event will be logged if the switch detects the same source MAC address on two separate interfaces in VLAN 100.

  4. Packets will be dropped and the event will be logged if the switch detects the same source MAC address on ge-0/0/6 and ge-0/0/7.

Answer: A

– Exhibit –

You have just connected and powered on four EX Series switches as shown in the exhibit. All of the switches have booted at the same time and have the default STP configuration.

Which two statements describe the STP roles of the switches?

  1. The port connecting Switch A to Switch B is Switch A#39;s root port.

  2. The port connecting Switch A to Switch C is Switch A#39;s root port.

  3. The port connecting Switch A to Switch C is Switch C#39;s root port.

  4. The port connecting Switch C to Switch B is Switch C#39;s designated port.

Answer: B,D

Question No: 394 – (Topic 4)

Your network consists of three OSPF routers as shown below: R1 – R2 – R3

You run the show ospf neighbor command on R2. The output shows no data in the output for OSPF neighbors.

Which three actions will troubleshoot the adjacency problem for Router R2? (Choose three.)

  1. Verify the physical and data link layer connectivity on Routers R1, R2, and R3.

  2. Look for incorrect settings for MTU on Routers R1 and R3.

  3. Look for mismatched configurations on Routers R1, R2, and R3 for IP subnet/mask, area number, and area type.

  4. Verify Router R1 and R3 to see if they are stuck in 2-way state.

  5. Look for mismatched configurations on Routers R1, R2, and R3 for authentication, hello/dead interval, and network type.

Answer: A,C,E

Question No: 395 – (Topic 4)

Which two statements accurately describe VRRP? (Choose two.)

  1. The master VRRP router sends periodic announcements to all other VRRP routers in the group.

  2. You can set the value of the TTL field for VRRP packets.

  3. VRRP routers communicate using multicast address 224.0.0.5.

  4. Each VRRP group uses a single MAC address.

Answer: A,D

Question No: 396 – (Topic 4)

– Exhibit –

user@routergt; show configuration | no-more

}

Local via ge-0/0/1.0

– Exhibit –

What is causing the behavior shown in the exhibit?

  1. The software is ignoring the fbf routing instance because it uses a reserved name.

  2. The software is ignoring the default route in the fbf routing instance because there is no default route in the main routing instance.

  3. The software is not able to find an interface on the router configured with the 10.210.12.129 address.

  4. The software is not able to resolve the next hop of the default route in the fbf routing instance.

Answer: D

Question No: 397 – (Topic 4)

What does an ABR between a backbone area and a totally stubby area inject into the totally stubby area?

  1. an LSA Type 4

  2. an LSA Type 5

  3. an external route

  4. a default route

Answer: D

Question No: 398 – (Topic 4)

Ensurepass 2018 PDF and VCE

Referring to the exhibit, which interfaces will receive a packet sent to MAC address 00:05:85:7F:EB. 80 from the user with IP address 10.10.10.10?

A. 0/0/3 and 0/0/22

B. 0/0/9 and 0/0/23

C. 0/0/3, 0/0/9, 0/0/22, and 0/0/23

D. 0/0/1, 0/0/3, 0/0/9, 0/0/22, and 0/0/23

Answer: A

Question No: 399 – (Topic 4)

Routers R1, R2, R3, and R4 are all connected on the same OSPF network segment. While viewing the output of the show ospf neighbor command on R1, you notice that the interface towards R2 is always in the 2Way state.

What would cause this state?

  1. R1 is a DR device and R2 is a DROther device.

  2. R1 and R2 are both DROther devices.

  3. R1 and R2 are both BDR devices.

  4. R1 is a DROther device and R2 is a DR device.

Answer: B

Question No: 400 – (Topic 4)
