A Change the network type to point-to-murpont under WAN interface

B. Enable virtual Inks

Answer: A, D

Question No: 173 – (Topic 7)

A network engineer is considering enabling load balancing with EIGRP. Which consideration should be analyzed?

  1. EIGRP allows a maximum of four paths across for load balancing traffic.

  2. By default, EIGRP uses a default variance of 2 for load balancing.

  3. EIGRP unequal path load balancing can result in routing loops.

  4. By default, EIGRP performs equal cost load balancing at least across four equal cost paths.

Answer: D

Question No: 174 – (Topic 7)

Which security feature can you enable to control access to the vty lines on a router?

  1. exec-time out

  2. logging

  3. username and password

  4. transport output

Answer: C

Question No: 175 – (Topic 7)

After reviewing the EVN configuration, a network administrator notices that a predefined EVN, which is known as 鈥渧net global鈥?was configured. What is the purpose of this EVN?

  1. It defines the routing scope for each particular EVN edge interface.

  2. It aggregates and carries all dot1q tagged traffic.

  3. It refers to the global routing context and corresponds to the default RIB.

  4. It safeguards the virtual network that is preconfigured to avoid mismatched routing


Answer: C

Question No: 176 – (Topic 7)

A network administrator creates a static route that points directly to a multiaccess interface, instead of the next-hop IP address. The administrator notices that Cisco Express Forwarding ARP requests are being sent to all destinations. Which issue might this configuration create?

  1. Low bandwidth usage

  2. High memory usage

  3. Cisco Express Forwarding routing loop

  4. High bandwidth usage

  5. IP route interference

Answer: C

Question No: 177 – (Topic 7)

A network engineer applies the command ip tcp adjust-mss lt;bytesgt; under interface configuration mode. What is the result?

  1. The probability of SYN packet truncation is increased.

  2. The UDP session is inversely affected.

  3. The probability of dropped or segmented TCP packets is decreased.

  4. The optimum MTU value for the interface is set.

Answer: C

Question No: 178 – (Topic 7)

An engineer executes the ip flow ingress command in interface configuration mode. What is the result of this action?

  1. It enables the collection of IP flow samples arriving to the interface.

  2. It enables the collection of IP flow samples leaving the interface.

  3. It enables IP flow while disabling IP CEF on the interface.

  4. It enables IP flow collection on the physical interface and its subinterfaces.

Answer: A

Question No: 179 – (Topic 7)

How does an IOS router process a packet that should be switched by Cisco Express Forwarding without an FIB entry?

  1. by forwarding the packet

  2. by dropping the packet

  3. by creating a new FIB entry for the packet

  4. by looking in the routing table for an alternate FIB entry

Answer: B

Question No: 180 – (Topic 7)

Refer to the exhibit.


Which option prevents routing updates from being sent to the DHCP router, while still allowing routing update messages to flow to the Internet router and the distribution switches?

  2. Core(config-router)# passive-interface Gi0/0 Core(config-router)# passive-interface Gi3/1 Core(config-router)# passive-interface Gi3/2 DHCP(config-router)# no passive- interface Gi1/0

  3. Core(config-router)# passive-interface default Core(config-router)# no passive-interface Gi0/0 Core(config-router)# no passive-interface Gi3/1 Core(config-router)# no passive- interface Gi3/2

  4. Internet(config-router)# passive-interface default Core(config-router)# passive-interface default DSW1(config-router)# passive-interface default DSW2(config-router)# passive- interface default
