Q41. DRAG DROP
Drag and drop the NHRP flag on the left to the corresponding meaning on the right.

Q43. Refer to the exhibit.
You discover that only 1.5 Mb/s of web traffic can pass during times of congestion on the given network.
Which two options are possible reasons for this limitation? (Choose two.)
A. The web traffic class has too little bandwidth reservation.
B. Video traffic is using too much bandwidth.
C. The service-policy is on the wrong interface.
D. The service-policy is going in the wrong direction.
E. The NAT policy is adding too much overhead.
Answer: A,B
Explanation:
In this example, the web traffic will fall into the default class, which is only 15 percent of the 10Mbps Internet connection (1.5Mbps). Meanwhile, video traffic is allowed 50% of the 10 Mbps.
Q44. DRAG DROP
Drag and drop each step in the performance-monitoring configuration process on the left into the correct order on the right.
Answer:
Q45. Refer to the exhibit.

A. The VLAN is inactive or has been removed from the VLAN database.
B. STP is in a forwarding state on the port.
C. A Layer 2 access port is configured with VLAN10, but is in a down/down state.
D. The autostate exclude feature was used on interface VLAN10.
Answer: A,C

Q47. Which two statements about port ACLs are true? (Choose two.)
A. Port ACLs are supported on physical interfaces and are configured on a Layer 2 interface on a switch.
B. Port ACLs support both outbound and inbound traffic filtering.
C. When it is applied to trunk ports, the port ACL filters only native VLAN traffic.
D. When it is applied to a port with voice VLAN, the port ACL filters both voice and data VLAN traffic.
Answer: A,D
Explanation:
PACLs filter incoming traffic on Layer 2 interfaces, using Layer 3 information, Layer 4 header information, or non-IP Layer 2 information The port ACL (PACL) feature provides the ability to perform access control on specific Layer 2 ports. A Layer 2 port is a physical LAN or trunk port that belongs to a VLAN. Port ACLs perform access control on all traffic entering the specified Layer 2 port, including voice and data VLANs that may be configured on the port. Port ACLs are applied only on the ingress traffic.

Q48. For which two conditions is Cisco Express Forwarding recursion disabled by default when the BGP Prefix Independent Convergence functionality is enabled? (Choose two.)
A. next hops learned with a /24 mask
B. next hops learned with any mask shorter than /32
C. next hops learned with a /32 mask
D. next hops that are directly connected
Answer: C,D
Explanation:
Recursion is the ability to find the next longest matching path when the primary path goes down. When the BGP PIC feature is not installed, and if the next hop to a prefix fails, Cisco Express Forwarding finds the next path to reach the prefix by recursing through the FIB to find the next longest matching path to the prefix. This is useful if the next hop is multiple
hops away and there is more than one way of reaching the next hop.
However, with the BGP PIC feature, you may want to disable Cisco Express Forwarding recursion for the following reasons:
. Recursion slows down convergence when Cisco Express Forwarding searches all the FIB entries.
. BGP PIC Edge already precomputes an alternate path, thus eliminating the need for Cisco Express Forwarding recursion.
When the BGP PIC functionality is enabled, Cisco Express Forwarding recursion is disabled by default for two conditions:
. For next hops learned with a /32 network mask (host routes)
. For next hops that are directly connected
For all other cases, Cisco Express Forwarding recursion is enabled.

Q49. Which bit should be set in the link-state PDU of an IS-IS L1/L2 router to indicate that it is a potential exit point of the area?
A. the ABR bit
B. the ATT bit
C. the down bit
D. the P bit
Answer: B
Explanation:
Default routing is achieved in two distinct ways with Integrated IS-IS:
. Attached bit—Set by a Level 1/Level 2 router in its own Level 1 LSP and used to indicate to all Level 1 routers (within the area) that this router is a potential exit point of the area. Level 1-only routers will default to the nearest attached Level 2 router.
. Default information originate—Can be configured in Level 1 as well as Level 2. The default route (0.0.0.0/0) is inserted in the router LSP (Level 1 or Level 2, according to the configuration command) and the LSP is flooded according to the router type (Level 1 or Level 2). A Level 2 router doesn't need to have a default route to originate a default route.

Q50. 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).
