Question No: 341 – (Topic 4)

Your router has formed two BGP peering relationships and received a route to 64.60.10.0/24 from each peer. The router has verified the next-hop address can be reached for both peers.

What is the next step to determine which path is selected for the routing table?

  1. Prefer the lowest origin value.

  2. Prefer the shortest AS-path length.

  3. Prefer the lowest local-preference value.

  4. Prefer the highest local-preference value.

Answer: D

Question No: 342 – (Topic 4)

    user@switch# set aggregated-devices ethernet device-count 1 [edit interfaces]

    user@switch# set ae1 aggregated-ether-options minimum-links 1 user@switch# set ae1 aggregated-ether-options link-speed 10g user@switch# set ae1 unit 0 family inet address 192.168.1.0/24 user@switch# set xe-0/1/0 ether-options 802.3ad ae1 user@switch# set xe-1/1/0 ether-options 802.3ad ae1

  2. [edit chassis]

    user@switch# set chassis aggregated-devices ethernet device-count 2 [edit interfaces]

    user@switch# set interface ae0 aggregated-ether-options minimum-links 1

    user@switch# set interface ae0 aggregated-ether-options link-speed 10g user@switch# set interface ae0 unit 0 family inet address 192.168.1.0/24 user@switch# set interface xe-0/1/0 ether-options 802.3ad ae0 fast user@switch# set interface xe-1/1/0 ether-options 802.3ad ae0 fast

  3. [edit chassis]

    user@switch# set chassis aggregated-devices ethernet device-count 1 [edit interfaces]

    user@switch# set interface ae0 aggregated-ether-options minimum-links 1 user@switch# set interface ae0 aggregated-ether-options link-speed 10g user@switch# set interface ae0 unit 0 family inet address 192.168.1.0/24 user@switch# set interface xe-0/1/0 ether-options 802.3ad ae0 fast user@switch# set interface xe-1/1/0 ether-options 802.3ad ae0 fast

Answer: D

Question No: 344 – (Topic 4)

Which statement describes the Spanning Tree Protocol (STP)?

  1. A switching protocol used to carry default VLANs.

  2. A port security feature used to limit MAC addresses on a port.

  3. A switching protocol that prevents loops.

  4. A high availability protocol used to gracefully restart a switch.

Answer: C

Reference:JNCIS-ENT Switching Study Guide, Spanning Tree 鈥?Chapter 3-1

Question No: 345 – (Topic 4)

What is the purpose of the native VLAN?

  1. The native VLAN is used to assign the trunk#39;s default VLAN if a global default VLAN is not configured.

  2. The native VLAN is only used on VoIP interfaces to allow a separate VLAN-ID for the voice VLAN and data VLAN.

  3. The native VLAN assumes VLAN 1 when no default VLAN is configured.

  4. The native VLAN allows the interface to accept untagged packets.

Answer: D

Question No: 346 – (Topic 4)

  4. out-delay

Answer: B

Question No: 347 – (Topic 4)

Which two steps must you perform? (Choose two.)

  1. Assign a VLAN ID to the Layer 3 VLAN interface.

  2. Assign at least one Layer 3 address to each VLAN.

  3. Assign interfaces configured as family Ethernet-switching to VLAN A and VLAN B.

  4. Assign interfaces configured as family inet to VLAN A and VLAN B.

Answer: B,C

Question No: 348 – (Topic 4)

Which two statements describe the behavior of Dynamic ARP Inspection? (Choose two.)

  1. Dynamic ARP Inspection is disabled by default.

  2. Dynamic ARP Inspection is enabled on individual ports.

  3. Dynamic ARP Inspection is enabled by default.

  4. Dynamic ARP Inspection is enabled on individual VLANs.

Answer: A,D

Question No: 349 – (Topic 4)

– Exhibit –

{master:0}[edit]

user@router# show interfaces ge-0/0/1 {

unit 0 {

family ethernet-switching { port-mode access;

vlan { members data;

}

}

}

}

{master:0}[edit]

user@router# show ethernet-switching-options voip {

interface ge-0/0/1.0 {

vlan voice;

forwarding-class assured-forwarding;

}

}

{master:0}[edit] user@router# show vlans data {

vlan-id 10;

}

voice { vlan-id 20;

}

– Exhibit –

Given the configuration in the exhibit, which VLAN or VLANs would be tagged VLANs?

  1. The voice VLAN and the data VLAN

  2. Only the voice VLAN

  3. Both VLANs are untagged

  4. The data VLAN

Answer: B

Question No: 350 – (Topic 4)

– Exhibit –

policy-statement load-balance { from {

route-filter 172.24.0.0/24 exact;

route-filter 172.24.1.0/24 exact;

}

then {

load-balance per-packet;

}

}

– Exhibit –
