Q211. Which three statements are true about an EtherChannel? (Choose three.) 

A. PAGP and LACP can be configured on the same switch if the switch is not in the same EtherChannel. 

B. EtherChannel ports in suspended state can receive BPDUs but cannot send them. 

C. An EtherChannel forms between trunks that are using different native VLANs. 

D. LACP can operate in both half duplex and full duplex, if the duplex setting is the same on both ends. 

E. Ports with different spanning-tree path costs can form an EtherChannel. 

Answer: A,B,E 

Explanation: 

Answer A. EtherChannel groups running PAgP and LACP can coexist on the same switch or on different switches in the stack. Individual EtherChannel groups can run either PAgP or LACP, but they cannot interoperate. 

Answer B: 

EtherChannel Member Port States 

Port States 

Description 

bundled 

The port is part of an EtherChannel and can send and receive BPDUs and data traffic. 

suspended 

The port is not part of an EtherChannel. The port can receive BPDUs but cannot send them. Data traffic is blocked. 

standalone 

The port is not bundled in an EtherChannel. The port functions as a standalone data port. The port can send and receive BPDUs and data traffic. 

Answer E. Ports with different spanning-tree path costs can form an EtherChannel if they are otherwise compatibly configured. Setting different spanning-tree path costs does not, by itself, make ports incompatible for the formation of an EtherChannel.

Q212. DRAG DROP 

Drag and drop each SNMP security model and level on the left to the corresponding mode of authentication on the right. 


Answer: 



Q213. Which two statements about the default behavior of IS-IS are true? (Choose two.) 

A. The default IS-IS router type is L1/L2. 

B. The default IS-IS metric type is wide. 

C. The default IS-IS interface circuit type is L1/L2. 

D. By default, two IS-IS routers must use the same hello interval and hold timer in order to become neighbors. 

Answer: A,C 


Q214. In a nonbackbone OSPF area, all traffic that is destined to the Internet is routed by using a default route that is originated by the ABR. Which change in the configuration of the OSPF area type causes traffic from that area that is destined to the Internet to be dropped? 

A. The OSPF area changes from NSSA to totally stubby area. 

B. The OSPF area changes from NSSA to regular area. 

C. The OSPF area changes from stub area to totally stubby area. 

D. The OSPF area changes from stub area to NSSA. 

Answer: D 

Explanation: 

The ABR for the NSSA generates the default route, but not by default. To force the ABR to generate the default route, use the area <area id> nssa default-information originate command. The ABR generates a Type 7 LSA with the link-state ID 0.0.0.0 and is advertised inside the NSSA. This default route will be propagated inside the NSSA as Type 7 LSA

Q215. On a broadcast interface, which two OSPF states support BFD sessions? (Choose two.) 

A. DR 

B. BDR 

C. DROTHER 

D. 2WAY 

E. FULL 

F. ACTIVE 

Answer: A,B

Q216. DRAG DROP 

Drag each show command on the left to the description of its output on a PE router on the right. 


Answer: 



Q217. DRAG DROP 

Drag and drop each step of the Unicast RPF process on the left into the correct order on the right. 


Answer: 



Q218. According to RFC 4577, OSPF for BGP/MPLS IP VPNs, when must the down bit be set? 

A. when an OSPF route is distributed from the PE to the CE, for Type 3 LSAs 

B. when an OSPF route is distributed from the PE to the CE, for Type 5 LSAs 

C. when an OSPF route is distributed from the PE to the CE, for Type 3 and Type 5 LSAs 

D. when an OSPF route is distributed from the PE to the CE, for all types of LSAs 

Answer: C 

Explanation: 

If an OSPF route is advertised from a PE router into an OSPF area, the Down bit (DN) is set. Another PE router in the same area does not redistribute this route into iBGP of the MPLS VPN network if down is set. 

RFC 4577 says: 

“When a type 3 LSA is sent from a PE router to a CE router, the DN bit in the LSA Options field MUST be set. This is used to ensure that if any CE router sends this type 3 LSA to a PE router, the PE router will not redistribute it further. When a PE router needs to distribute to a CE router a route that comes from a site outside the latter’s OSPF domain, the PE router presents itself as an ASBR (Autonomous System Border Router), and distributes the route in a type 5 LSA. The DN bit [OSPF-DN] MUST be set in these LSAs to ensure that they will be ignored by any other PE routers that receive them.” 

For more information about Down bit according to RFC 4577 please read more herE. http://tools.ietf.org/html/rfc4577#section-4.2.5.1. 


Q219. What is the VLAN ID range of VLANs that are eligible for pruning? 

A. 2 through 1001 

B. 1 through 1005 

C. 1 through 4096 

D. 2 through 1005 

Answer: A 


Q220. Refer to the exhibit. 


Which feature can R1 use to fail over from R2 to R3 if the address for R2 becomes unavailable? 

A. object tracking 

B. HSRP 

C. GLBP 

D. LACP 

Answer: A 

Explanation: 

The object tracking feature allows you to create a tracked object that multiple clients can use to modify the client behavior when a tracked object changes. Several clients register their interest with the tracking process, track the same object, and take different actions when the object state changes. 

Clients include the following features: 

. Embedded Event Manager (EEM) 

. Gateway Load Balancing Protocol (GLBP) 

. Hot Standby Redundancy Protocol (HSRP) 

. Virtual port channel (vPC) 

. Virtual Router Redundancy Protocol (VRRP) 

The object tracking monitors the status of the tracked objects and communicates any changes made to interested clients. Each tracked object is identified by a unique number that clients can use to configure the action to take when a tracked object changes state.
