Q1. In which type of EIGRP configuration is EIGRP IPv6 VRF-Lite available?
A. stub
B. named mode
C. classic mode
D. passive
Answer: B
Explanation:
The EIGRP IPv6 VRF Lite feature provides EIGRP IPv6 support for multiple VRFs. EIGRP for IPv6 can operate in the context of a VRF. The EIGRP IPv6 VRF Lite feature provides
separation between routing and forwarding, providing an additional level of security because no communication between devices belonging to different VRFs is allowed unless it is explicitly configured. The EIGRP IPv6 VRF Lite feature simplifies the management and troubleshooting of traffic belonging to a specific VRF. The EIGRP IPv6 VRF Lite feature is available only in EIGRP named configurations.

Q2. Which type of OSPF packet is an OSPF link state update packet?
A. type 1
B. type 2
C. type 3
D. type 4
E. type 5
Answer: D
Explanation:
Link State Update packets are OSPF packet type 4. These packets implement the flooding of link state advertisements. Each Link State Update packet carries a collection of link state advertisements one hop further from its origin. Several link state advertisements may be included in a single packet.

Q3. Refer to the exhibit.
Which three statements about the output are true? (Choose three.)
A. An mrouter port can be learned by receiving a PIM hello packet from a multicast router.
B. This switch is configured as a multicast router.
C. Gi2/0/1 is a trunk link that connects to a multicast router.
D. An mrouter port is learned when a multicast data stream is received on that port from a multicast router.
E. This switch is not configured as a multicast router. It is configured only for IGMP snooping.
F. IGMP reports are received only on Gi2/0/1 and are never transmitted out Gi2/0/1 for VLANs 10 and 20.
Answer: A,B,C
Explanation:
In this example, the switch has been configured as a multicast router since IGMP snooping has been enabled. All mrouters can learn about other mrouters by receiving a PIM hello packet from another multicast router. Also, since two different VLANs are being used by the same port of gi 2/0/1, it must be a trunk link that connects to another multicast router.
Q4. Which two options are differences between TACACS+ and RADIUS using AAA? (Choose two.)
A. Only TACACS+ limits the protocols that are supported.
B. Only RADIUS combines accounting and authentication.
C. Only TACACS+ uses TCP.
D. Only RADIUS combines authorization and accounting.
E. Only RADIUS encrypts the password in packets from the client to the server. But leaves the body of the message unencrypted.
Answer: C,E
Q5. Which two operating modes does VPLS support? (Choose two.)
A. transport mode
B. strict mode
C. port mode
D. loose mode
E. VLAN mode
F. dynamic mode
Answer: C,E
Q6. Which three components comprise the structure of a pseudowire FEC element? (Choose three.)
A. pseudowire ID
B. pseudowire type
C. control word
D. Layer 3 PDU
E. header checksum
F. type of service
Answer: A,B,C
Explanation:
The Pseudowire ID FEC element has the following components:
. Pseudowire ID FEC — The first octet has a value of 128 that identifies it as a Pseudowire ID FEC element.
. Control Word Bit (C-Bit) — The C-bit indicates whether the advertising PE expects the control word to be present for pseudowire packets. A control word is an optional 4-byte field located between the MPLS label stack and the Layer 2 payload in the pseudowire packet. The control word carries generic and Layer 2 payload-specific information. If the C-bit is set to 1, the advertising PE expects the control word to be present in every pseudowire packet on the pseudowire that is being signaled. If the C-bit is set to 0, no control word is expected to be present.
. Pseudowire Type — PW Type is a 15-bit field that represents the type of pseudowire. Examples of pseudowire types are shown in Table 6-1.
. Pseudowire Information Length — Pseudowire Information Length is the length of the Pseudowire ID field and the interface parameters in octets. When the length is set to 0, this FEC element stands for all pseudowires using the specified Group ID. The Pseudowire ID and Interface Parameters fields are not present.
. Group ID — The Group ID field is a 32-bit arbitrary value that is assigned to a group of pseudowires.
. Pseudowire ID — The Pseudowire ID, also known as VC ID, is a non-zero, 32-bit identifier that distinguishes one pseudowire from another. To connect two attachment circuits through a pseudowire, you need to associate each one with the same Pseudowire ID.
. Interface Parameters — The variable-length Interface Parameters field provides attachment circuit-specific information, such as interface MTU, maximum number of concatenated ATM cells, interface description, and so on.

Q7. An NSSA area has two ABRs connected to Area 0. Which statement is true?
A. Both ABRs translate Type-7 LSAs to Type-5 LSAs.
B. The ABR with the highest router ID translates Type-7 LSAs to Type-5 LSAs.
C. Both ABRs forward Type-5 LSAs from the NSSA area to backbone area.
D. No LSA translation is needed.
Answer: B
Q8. Into which two pieces of information does the LISP protocol split the device identity? (Choose two.)
A. Routing Locator
B. Endpoint Identifier
C. Resource Location
D. Enterprise Identifier
E. LISP ID
F. Device ID
Answer: A,B
Q9. Which two options are requirements for Control-Plane Policing? (Choose two.)
A. Cisco Express Forwarding must be enabled globally.
B. Cisco Discovery Protocol must be disabled in the control plane.
C. A crypto policy must be installed.
D. A loopback address must be configured for device access.
E. A class map must be configured to identify traffic.
Answer: A,E
Q10. Which statement about the EIGRP RTO is true?
A. It is six times the SRTT.
B. It is the time that it normally takes for an update to be received by a peer.
C. It is the time that it normally takes to receive a reply to a query.
D. It is the average time that it takes for a reliable packet to be acknowledged.
Answer: A
Explanation:
The RTO is typically six times the SRTT, the value may vary from a minimum of 200 microseconds (ms) to a maximum of 5 seconds (s).
