Q441. DRAG DROP
Drag and drop each BGP attribute on the left to the matching description on the right.
Q442. Which two options about PIM-DM are true? (Choose two.)
A. PIM-DM initally floods multicast traffic throughout the network.
B. In a PIM-DM network, routers that have no upstream neighbors prune back unwanted traffic.
C. PIM-DM supports only shared trees.
D. PIM-DM uses a pull model to deliver multicast traffic.
E. PIM-DM cannot be used to build a shared distribution tree.
Q443. Refer to the exhibit.
Which configuration can you implement on PE-1 to allow CE-1 to receive delegated IPv6 prefixes?
A. Exhibit A
B. Exhibit B
C. Exhibit C
D. Exhibit D
E. Exhibit E
Q444. Refer to the exhibit.
Which statement is true?
A. 2001:DB8::1/128 is a local host route, and it can be redistributed into a dynamic routing protocol.
B. 2001:DB8::1/128 is a local host route, and it cannot be redistributed into a dynamic routing protocol.
C. 2001:DB8::1/128 is a local host route that was created because ipv6 unicast-routing is not enabled on this router.
D. 2001:DB8::1/128 is a route that was put in the IPv6 routing table because one of this router's loopback interfaces has the IPv6 address 2001:DB8::1/128.
The local routes have the administrative distance of 0. This is the same adminstrative distance as connected routes. However, when you configure redistributed connected under any routing process, the connected routes are redistributed, but the local routes are not. This behavior allows the networks to not require a large number of host routes, because the networks of the interfaces are advertised with their proper masks. These host routes are only needed on the router that owns the IP address in order to process packets destined to that IP address.
It is normal for local host routes to be listed in the IPv4 and IPv6 routing table for IP addresses of the router's interfaces. Their purpose is to create a corresponding CEF entry as a receive entry so that the packets destined to this IP address can be processed by the router itself. These routes cannot be redistributed into any routing protocol.
Q445. What is the destination multicast MAC address for BPDUs on the native VLAN, for a switch that is running 802.1D?
A. 0185. C400. 0000
If the native vlan is 1:
A STP BPDU for VLAN 1 will be sent untagged to MAC 0180.c200.0000 (this is the
common spanning tree)
A PVST+ BPDU for VLAN 1 will be sent untagged to MAC 0100.0ccc.cccd
A PVST+ BPDU for all other vlans will be sent with a 802.1Q tag to MAC 0100.0ccc.cccd
(with a PVID = to the VLAN)
If the native vlan is not 1:
A STP BPDU for VLAN 1 will be sent untagged (on the native vlan) to MAC
0180.c200.0000 (this is the common spanning tree)
A PVST+ BPDU for VLAN1 will be sent with a 802.1Q tag to MAC 0100.0ccc.cccd (with a PVID=1)
A PVST+ BPDU for the native vlan will be sent untagged to MAC 0100.0ccc.cccd (with a PVID=native vlan)
A PVST+ BPDU for all other vlans will be sent with a 802.1Q tag to MAC 0100.0ccc.cccd (with a PVID = to the VLAN)
Q446. Which two commands enable OSPF graceful shutdown? (Choose two.)
A. nsf cisco
B. ip ospf shutdown
D. nsf ietf helper disable
Q447. DRAG DROP
Drag and drop the NetFlow Export feature on the left to the NetFlow version that first supported it on the right.
Q448. Refer to the exhibit.
Why is the neighbor relationship between R2 and R4 shown as ES-IS?
A. because there is an MTU mismatch between R2 and R4
B. because interface S3/0 of R4 is configured as L1/L2
C. because interface S3/0 of R2 is configured as L1
D. because there is a hello interval mismatch between R2 and R4
With IS-IS we will see ES-IS when one of the following is true:
So in this question because we do not know about the other side’s “show CLNS neighbor” A must be the better choose.
Q449. Which two options are BGP attributes that are updated when router sends an update to its eBGP peer? (Choose two.)
B. local preference
AS_Path describes the inter-AS path taken to reach a destination. It gives a list of AS Numbers traversed when reaching to a destination. Every BGP speaker when advertising a route to a peer will include its own AS number in the NLRI. The subsequent BGP speakers who advertise this route will add their own AS number to the AS_Path, the subsequent AS numbers get prepended to the list. The end result is the AS_Path attribute is able to describe all the autonomous systems it has traversed, beginning with the most recent AS and ending with the originating AS.
NEXT_HOP Attribute specifies the next hop IP address to reach the destination advertised in the NLRI. NEXT_HOP is a well-known mandatory attribute that is included in every eBGP update.
Q450. Refer to the exhibit.
Which statement is true about why the first-hop PIM IPv6 router is stuck in registering?
A. The scope of the IPv6 multicast address is link-local.
B. The outgoing interface for the IPv6 multicast group should not be a tunnel interface.
C. The R-bit is set in the IPv6 address, but this is not an embedded RP multicast IPv6 address.
D. The S flag should not be set on a first-hop PIM router.
E. A multicast IPv6 address does not start with FF.
.R bit: RP bit: R = 1 indicates the address embeds the address of the Rendezvous Point (RP). The embedded RP address needs to begin with the prefix FF70::/12, But here we see that the address is FF7E::1234.
