A new backup connection is being deployed on a remote site router. The stability of the connection
has been a concern. In order to provide more information to EIGRP regarding this interface, you
wish to incorporate the “reliability” cost metric in the EIGRP calculation with the command metric
weights 1 0 1 0 1.
What impact will this modification on the remote site router have for other existing EIGRP
neighborships from the same EIGRP domain?
A. Existing neighbors will immediately begin using the new metric.
B. Existing neighbors will use the new metric after clearing the EIGRP neighbors.
C. Existing neighbors will resync, maintaining the neighbor relationship.
D. All existing neighbor relationships will go down.
Refer to the exhibit.
R1 has an EBGP session to ISP 1 and an EBGP session to ISP 2. R1 receives the same prefixes
through both links.
Which configuration should be applied so that the link between R1 and ISP 2 will be preferred for
outgoing traffic (R1 to ISP 2)?
A. Increase local preference on R1 for received routes
B. Decrease local preference on R1 for received routes
C. Increase MED on ISP 2 for received routes
D. Decrease MED on ISP 2 for received routes
Local preference is an indication to the AS about which path has preference to exit the AS in order
to reach a certain network. A path with higher local preference is preferred more. The default value
of preference is 100.
Why would a rogue host that is running a DHCP server on a campus LAN network present a
A. It may allocate IP addresses from an unknown subnet to the users.
B. All multicast traffic can be sniffed by using the DHCP multicast capabilities.
C. The CPU utilization of the first hop router can be overloaded by exploiting DHCP relay open
D. A potential man-in-the-middle attack can be used against the clients.
Which two are effects of connecting a network segment that is running 802.1D to a network
segment that is running 802.1w? (Choose two.)
A. The entire network switches to 802.1D and generates BPDUs to determine root bridge status. B.
A migration delay of three seconds occurs when the port that is connected to the 802.1D bridge
C. The entire network reconverges and a unique root bridge for the 802.1D segment, and a root
bridge for the 802.1w segment, is chosen.
D. The first hop 802.1w switch that is connected to the 802.1D runs entirely in 802.1D compatibility
mode and converts the BPDUs to either 802.1D or 802.1w BPDUs to the 802.1D or 802.1w
segments of the network.
E. Classic 802.1D timers, such as forward delay and max-age, will only be used as a backup, and
will not be necessary if point-to-point links and edge ports are properly identified and set by the
Each port maintains a variable that defines the protocol to run on the corresponding segment. A
migration delay timer of three seconds also starts when the port comes up. When this timer runs,
the current STP or RSTP mode associated to the port is locked. As soon as the migration delay
expires, the port adapts to the mode that corresponds to the next BPDU it receives. If the port
changes its mode of operation as a result of a BPDU received, the migration delay restarts.
802.1D works by the concept that the protocol had to wait for the network to converge before it
transitioned a port into the forwarding state. With Rapid Spanning Tree it does not have to rely on
any timers, the only variables that that it relies on is edge ports and link types.
Any uplink port that has an alternate port to the root can be directly placed into the forwarding
state (This is the Rapid convergence that you speak of “restored quickly when RSTP is already in
use?”). This is what happened when you disconnected the primary look; the port that was ALT,
moved to FWD immediately, but the switch also still needs to create a BDU with the TC bit set to
notify the rest of the network that a topology has occurred and all non-edge designated ports will
transition to BLK, LRN, and then FWD to ensure there are no loops in the rest of the network. This
is why if you have a host on a switchport, and you know for a fact that it is only one host, enable
portfast to configure the port as an edgeport so that it does not have to transition to all the STP
Which command is used to enable EtherChannel hashing for Layer 3 IP and Layer 4 port-based
A. mpls ip cef
B. port-channel ip cef
C. mpls ip port-channel cef
D. port-channel load balance
E. mpls ip load-balance
F. ip cef EtherChannel channel-id XOR L4
G. ip cef connection exchange
Which three options are considered in the spanning-tree decision process? (Choose three.)
A. lowest root bridge ID
B. lowest path cost to root bridge
C. lowest sender bridge ID
D. highest port ID
E. highest root bridge ID
F. highest path cost to root bridge
Configuration bridge protocol data units (BPDUs) are sent between switches for each port.
Switches use s four step process to save a copy of the best BPDU seen on every port. When a
port receives a better BPDU, it stops sending them. If the BPDUs stop arriving for 20 seconds
(default), it begins sending them again.
Step 1 Lowest Root Bridge ID (BID)
Step 2 Lowest Path Cost to Root Bridge
Step 3 Lowest Sender BID
Step 4 Lowest Port ID

Refer to the exhibit.
What is the potential issue with this configuration?
A. There is no potential issue; OSPF will work fine in any condition.
B. Sub-optimal routing may occur since there is no area 1 adjacency between the ABRs.
C. This is a wrong OSPF configuration because all routers must be in area 0 only.
D. This is a wrong OSPF configuration because /30 requires 0.0.0.3 wild card.
How will EIGRPv6 react if there is an IPv6 subnet mask mismatch between the Global Unicast
addresses on a point-to-point link?
A. EIGRPv6 will form a neighbor relationship.
B. EIGRPv6 will not form a neighbor relationship.
C. EIGRPv6 will form a neighbor relationship, but with the log MSG: “EIGRPv6 neighbor not on a
D. EIGRPv6 will form a neighbor relationship, but routes learned from that neighbor will not be
installed in the routing table.
Answer: A Explanation:
Which two OSPF LSA types are new in OSPF version 3? (Choose two.)
B. NSSA external
C. Network link
D. Intra-area prefix
E. AS domain
New LSA Types
OSPFv3 carries over the seven basic LSA types we\’re familiar with from OSPFv2. However, the
type 1 and 2 LSAs have been re-purposed, as will be discussed in a bit. OSPFv3 also introduces
two new LSA types: Link and Intra-area Prefix.
In order to maintain security, with which hop count are IPv6 neighbor discovery packets sent?
