Question 1

Distribution layer: This layer includes LAN-based routers and layer 3 switches . When is a first-hop redundancy protocol needed in the distribution layer?

Accepted Answer

The distribution layer is responsible for routing traffic between the access layer and the core layer. A first-hop redundancy protocol is needed in the distribution layer when the design implements Layer 3 between the access switch and the distribution switch. This is because the first-hop redundancy protocol will provide redundancy for the default gateway, which is the IP address of the router that the hosts on the access switch use to reach the rest of the network.

Question 2

Assume that Telnet users of your company are experiencing delays caused by cyclic congestion spikes. Traffic analysis shows minimal use of UDP. Which technology can be used to solve this problem?

Accepted Answer

Weighted RED (Random Early Detection) is a congestion avoidance mechanism that can help manage congestion by preemptively dropping packets before a queue becomes full, thus preventing cyclic congestion spikes.

Question 3

When dealing with transparent caching, where should the Content Engines be placed?

Accepted Answer

Content Engines should be placed close to the end users to reduce latency and improve access speed by caching frequently accessed content locally.

Question 4

P4S-R2 and P4S-R3 are learning Network A and Network B through EBGP peering sessions as shown in the figure. P4S-R2 and P4S-R3 are also configured to peer by use of IBGP, and they are both advertising default routes through OSPF. Network A is not able to reach destinations on Network A; which step should be takes to solve this problem?

Question 5

Observe the topology presented in the following exhibit, there is a full mesh in the core and the PE-CE protocol is EIGRP. Which path is preferred from CE1 to CE3?

Question 6

You are the Cisco Network Designer in P4S. Which of these practices should you follow when designing a Layer 3 routing protocol?

Accepted Answer

Summarizing routes at the distribution layer helps to limit the scope of EIGRP queries or OSPF LSA propagation, which can improve network stability and convergence times.

Question 7

What can be prevented by configuring the password policy when using LDAP servers?

Accepted Answer

Configuring a password policy can help prevent dictionary attacks by enforcing strong password requirements, making it harder for attackers to guess passwords using common words or phrases.

Question 8

A certain service provider network has IPsec tunnels between PE router loopbacks and dual-homed PE routers. The service provider carries infrastructure routes by use of OSPF and carries tunnel endpoints by using BGP. What should the service provider do to provide fast convergence in the event of a link failure in its network?

Accepted Answer

Tuning OSPF on all routers can help achieve fast convergence by optimizing OSPF timers and parameters to quickly detect and respond to network changes, such as link failures.

Question 9

You are a network administrator for the P4S company, study the exhibit carefully. You are responsible for this small EIGRP network and you want to change the primary path from P4S-R5 to 10.1.2.0/24 so it passes through P4S-R2. How to modify the EIGRP metrics to change the path in this way?

Accepted Answer

The answer of You are a network administrator for the...

Question 10

Which item can reduce IP address spoofing effectively and dynamically?

Accepted Answer

Unicast Reverse Path Forwarding (uRPF) is a security feature that helps to prevent IP address spoofing by ensuring that packets have a valid source IP address that matches the routing table, effectively and dynamically verifying the legitimacy of incoming packets.

Question 11

Flex Links are a pair of a Layer 2 interfaces (switchports or port channels), where one interface is configured to act as a backup to the other. Which two statements are correct regarding Flex Links?

Question 13

Which one of the following technologies allows a router to route traffic according to the size of the incoming packet?

Accepted Answer

Policy-Based Routing (PBR) allows a router to make routing decisions based on various criteria, including the size of the incoming packet.

Question 14

You are a network designer for the P4S company, study the exhibit carefully. You are asked to design a Layer 2 VPN. Now, 90% of traffic from the remote branches of P4S comes to HQ. There are hubs and old switches at remotes not having dot1q capability. But at the remote branches, P4S has not the budget to invest in new equipment. Other than converting the remote branches to Layer 2 VPN, P4S would like to connect all the branches to the HQ site to make sure that the branches have access to dot1q capability. How to meet this requirement, if not, why?

Accepted Answer

Question 15

Which two components are of effective change management planning? (Choose two.)

Accepted Answer

The answer of Which two components are of effective change...

Question 16

Which option is correct in terms of designing a policy in which more than one class share a queue?

Accepted Answer

When multiple classes share a queue, it's important to consider the performance targets of each class to ensure that the shared resources meet the needs of all classes involved.

Question 17

Which statement about CiscoWorks 2000 Inventory Manager is true?

Accepted Answer

CiscoWorks 2000 Inventory Manager scans devices to gather hardware information, such as module types and serial numbers.

Question 18

Observe the following exhibit carefully. Router P4S-A receives a packet destined for loopback 10 on router P4S-D. Which path should this packet take on its way to the destination interface?

Accepted Answer

The answer of Observe the following exhibit carefully. Router P4S-A...

Question 19

Which statement correctly describes OSPF incremental SPF?

Accepted Answer

iSPF (incremental SPF) is a local optimization feature that allows a router to perform partial SPF calculations, reducing CPU load. It does not require coordination or configuration on other routers in the OSPF domain or area.

Question 20

The P4S company has just merged with the VR company. However, they keep IGP and BGP independent of each other. A common ISP provides them with services for their Internet connectivity. During the merge, the P4S company and the VR company will provision a point-to-point link between the two networks. What is the simplest design option that will allow data to travel between A and B without passing through the ISP?

Accepted Answer

Configuring EBGP between the two networks allows them to exchange routing information directly over the point-to-point link, ensuring data travels between them without going through the ISP. Blocking each other's routes from the ISP prevents routing loops and ensures traffic takes the direct path.
