Q211. Which algorithm heavily influenced the algorithm used by path-vector protocols?
A. Bellman-Ford
B. SPF
C. DUAL
D. Spanning-Tree
E. Adaptive
F. Deflection
Answer: A
Explanation:
A path vector protocol is a computer network routing protocol which maintains the path information that gets updated dynamically. Updates which have looped through the network and returned to the same node are easily detected and discarded. This algorithm is sometimes used in Bellman–Ford routing algorithms to avoid "Count to Infinity" problems.

Q212. Which two statements about OSPFv3 are true? (Choose two.)
A. It supports unicast address families for IPv4 and IPv6.
B. It supports unicast address families for IPv6 only.
C. It supports only one address family per instance.
D. It supports the use of a cluster ID for loop prevention.
E. It supports multicast address families for IPv4 and IPv6.
F. It supports multicast address families for IPv6 only.
Answer: A,C
Q213. Which two statements about HSRP are true? (Choose two.)
A. Its virtual MAC is 0000.0C07.Acxx.
B. Its multicast virtual MAC is 0000.5E00.01xx.
C. Its default configuration allows for pre-emption.
D. It supports tracking.
E. It supports unique virtual MAC addresses.
Answer: A,D
Explanation:
Default HSRP Configuration
Feature
Default Setting
HSRP version
Version 1
HSRP groups
None configured
Standby group number
0
Standby MAC address
System assigned as: 0000.0c07.acXX, where XX is the HSRP group number
Standby priority
100
Standby delay
0 (no delay)
Standby track interface priority
10
Standby hello time
3 seconds
Standby holdtime
10 seconds
. The standby track interface configuration command ties the router hot standby priority to the availability of its interfaces and is useful for tracking interfaces that are not configured for HSRP. When a tracked interface fails, the hot standby priority on the device on which tracking has been configured decreases by 10. If an interface is not tracked, its state changes do not affect the hot standby priority of the configured device. For each interface configured for hot standby, you can configure a separate list of interfaces to be tracked.
. The standby track interface-priority interface configuration command specifies how much to decrement the hot standby priority when a tracked interface goes down. When the interface comes back up, the priority is incremented by the same amount.

Q214. Refer to the exhibit.
Which statement about the debug behavior of the device is true?
A. The device debugs all IP events for 172.16.129.4.
B. The device sends all debugging information for 172.16.129.4.
C. The device sends only NTP debugging information to 172.16.129.4.
D. The device sends debugging information every five seconds.
Answer: A
Explanation:
This is an example of a conditional debug, where there is a single condition specified of IP address 172.16.129.4. So, all IP events for that address will be output in the debug.
Q215. Which three steps are necessary to enable SSH? (Choose three.)
A. generating an RSA or DSA cryptographic key
B. configuring the version of SSH
C. configuring a domain name
D. configuring VTY lines for use with SSH
E. configuring the port for SSH to listen for connections
F. generating an AES or SHA cryptographic key
Answer: A,C,D
Explanation:
Here are the steps:
1. Configure a hostname for the router using these commands.
yourname#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
yourname (config)#hostname LabRouter
LabRouter(config)#
2. Configure a domain name with the ip domain-name command followed by whatever you would like your domain name to be. I used CiscoLab.com.
LabRouter(config)#ip domain-name CiscoLab.com
3. We generate a certificate that will be used to encrypt the SSH packets using the crypto key generate rsa command.
Take note of the message that is displayed right after we enter this command. “The name for the keys will bE. LabRouter.CiscoLab.com” — it combines the hostname of the router along with the domain name we configured to get the name of the encryption key generated; this is why it was important for us to, first of all, configure a hostname then a domain name before we generated the keys.
Notice also that it asks us to choose a size of modulus for the key we’re about to generate.
The higher the modulus, the stronger the encryption of the key. For our example, we’ll use a modulus of 1024.
Q216. Refer to the exhibit.
What is a reason for the RIB-failure?
A. CEF is not enabled on this router.
B. The route 10.100.1.1/32 is in the routing table, but not as a BGP route.
C. The routing table has yet to be updated with the BGP route.
D. The BGP route is filtered inbound and hence is not installed in the routing table.
Answer: B
Explanation:
A rib-failure occurs when BGP tries to install the bestpath prefix into the RIB, but the RIB rejects the BGP route because a route with better administrative distance already exists in the routing table. An inactive Border Gateway Protocol (BGP) route is a route that is not installed in the RIB, but is installed in the BGP table as rib-failure. Example Topology Router 1 (R1) and router 2 (R2) have two parallel links; one links runs BGP AS 65535 and the other link runs Enhanced Interior Gateway Routing Protocol (EIGRP) AS 1. Both BGP and EIGRP are advertising the network 10.1.1.1/32 on R1.
R2 learns about the 1.1.1.1/32 route through both EIGRP and BGP, but installs only the EIGRP route in the routing table because of the lower administrative distance. Since the BGP route is not installed in the R2 routing table, the route appears as a rib-failure in the R2 BGP table.

Q217. Which two OSPF LSA types are flooded within the originating area? (Choose two.)
A. type 1, Router LSA
B. type 2, Network LSA
C. type 3, Network Summary LSA
D. type 4, ASBR Summary LSA
E. type 6, Group Membership LSA
F. type 9, Opaque LSA
Answer: A,B
Explanation:
OSPF relies on several types of Link State Advertisements (LSAs) to communicate link state information between neighbors. A brief review of the most applicable LSA types:
. Type 1 - Represents a router
. Type 2 - Represents the pseudonode (designated router) for a multiaccess link
. Type 3 - A network link summary (internal route)
. Type 4 - Represents an ASBR
. Type 5 - A route external to the OSPF domain
. Type 7 - Used in stub areas in place of a type 5 LSA LSA types 1 and 2 are found in all areas, and are never flooded outside of an area. They are only flooded within the area that they originated from.

Q218. Which two statements about IS-IS wide metrics are true? (Choose two.)
A. The wide metric is a 24-bit field.
B. The maximum link metric is 16777215.
C. R3 and R4 periodically advertise PNSP messages to synchronize the IS-IS database.
D. IS-IS devices that are enabled with wide metrics can become neighbors with a device that uses standard metrics.
E. The maximum link metric is 4261412864.
F. The maximum path metric is 16777215.
Answer: A,B
Q219. Which two Cisco Express Forwarding tables are located in the data plane? (Choose two.)
A. the forwarding information base
B. the label forwarding information base
C. the IP routing table
D. the label information table
E. the adjacency table
Answer: A,B
Explanation:
The control plane runs protocols such as OSPF, BGP, STP, LDP. These protocols are needed so that routers and switches know how to forward packets and frames.
The data plane is where the actual forwarding takes place. The data plane is populated based on the protocols running in the control plane. The Forwarding Information Base (FIB) is used for IP traffic and the Label FIB is used for MPLS.
Q220. Which two options are the two main phases of PPPoE? (Choose two.)
A. Active Discovery Phase
B. IKE Phase
C. Main Mode Phase
D. PPP Session Phase
E. Aggressive Mode Phase
F. Negotiation Phase
Answer: A,D
Explanation:
PPPoE is composed of two main phases:
Active Discovery Phase — In this phase, the PPPoE client locates a PPPoE server, called an access concentrator. During this phase, a Session ID is assigned and the PPPoE layer is established.
PPP Session Phase — In this phase, PPP options are negotiated and authentication is performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation method, allowing data to be transferred over the PPP link within PPPoE headers.
