Question No: 351 – (Topic 4)

When is MAC limiting performed on a frame from an unknown source MAC address?

  1. when the ingress PFE sends header information to RE

  2. when the ingress PFE performs a MAC address lookup

  3. when the PFE adds the MAC address to the bridge table

  4. when the RE adds the MAC address to the bridge table

Answer: A

Question No: 352 – (Topic 4)

In which two situations will the BGP next-hop attribute point to Router A? (Choose two.)

  1. When Router A sends routing updates to its EBGP peer Router B with multihop configured.

  2. When Router A sends routing updates to its IBGP peer Router B when route reflectors are not used.

  3. When Router A sends routing updates to its IBGP peer Router B when route reflectors are used.

  4. When Router A sends routing updates to its IBGP peer after redistributing routes to BGP from an IGP.

Answer: A,D

An IP tunnel connects two routers over the Internet as shown in the exhibit. Which two statements are correct? (Choose two.)

  1. A tunnel interface can serve as a next hop for static routes or participate in the network’s IGP.

  2. Routing protocols will always prefer a tunnel over a physical link because the tunnel is a one-hop link with the lowest cost path.

  3. You can ensure the IP tunnel serves as the backup path through administrative settings such as cost and route preference.

  4. IP tunnels are subject to the same simple firewall rules as the direct link between the two routers, because the original IP header contents are open for the transit devices to see.

Answer: A,C

Question No: 355 – (Topic 4)

You have an EX4200 in a Virtual Chassis configuration. You need to establish a console connection to the switch to troubleshoot an issue.

Which statement is correct?

  1. You must first determine which VC member is the master RE and connect to it.

  2. You must first determine which VC member is the backup RE and connect to it.

  3. You can connect to any member of the VC and your console session will be re-directed to the master RE.

  4. You can connect to any member of the VC but you will be connected to a local member and from there you must connect to the master RE.

Answer: C

Question No: 356 – (Topic 4)

Answer: C

Question No: 357 – (Topic 4)

– Exhibit –

user@R1# show interfaces ge-0/0/8 {

unit 0 { family inet {

address 172.25.100.2/24 { vrrp-group 10 {

virtual-address 172.25.100.1;

priority 200;

}

}

}

}

}

– Exhibit –

  2. The address 172.25.100.1 is only reachable on R1.

  3. The address 172.25.100.2 will only be reachable on the master of VRRP group 10.

  4. The address 175.25.100.1 will only be reachable on the master of VRRP group 10.

Answer: A,D

Question No: 358 – (Topic 4)

What are two purposes of MAC move limiting? (Choose two.)

  1. to prevent users from changing switch ports without approval

  2. to prevent Layer 2 loops

Answer: A,C

Question No: 359 – (Topic 4)

– Exhibit –

user@Switch-1# run show dhcp snooping binding DHCP Snooping Information:

MAC address IP address Lease (seconds) Type VLAN Interface 00:26:88:02:74:89 172.28.1.4 – static default ge-0/0/9.0

00:26:88:02:74:86 172.28.1.2 86113 dynamic default ge-0/0/6.0

00:26:88:02:74:87 172.28.1.3 86378 dynamic default ge-0/0/7.0

– Exhibit –

DHCP snooping is implemented on an EX Series switch. The results display a static MAC to IP binding on interface ge-0/0/9 as shown in the exhibit.

Which statement is correct?

  1. MAC address 00:26:88:02:74:89 is a static MAC address configured for a host attached to interface ge-0/0/9.

  2. MAC address 00:26:88:02:74:89 is a static MAC address to IP address binding in the DHCP server.

  3. MAC address 00:26:88:02:74:89 is a static MAC address to IP address configured on the L3 interface ge-0/0/9.

  4. MAC address 00:26:88:02:74:89 is a static address assigned using the command set interface ge-0/0/9.0 mac-allowed 00:26:88:02:74:89.

Answer: A

Question No: 360 – (Topic 4)
