You verify that both ends of the device are indeed running half duplex interfaces. Given that information which of the following answers is the most likely cause of this scenario? - Answer-The cable length is excessive - whenever you see lake collisions that is a telltale sign that your cable is running pastits maximum recommended length for example twisted-pair cables shouldn't be run further than 100 m ( 328ft) While configuring a load balancer between multiple systems which of the following must be configured in order to ensure proper connectivity during a fail over? - Answer-VIP - virtual IP an essential part of configuring load balance systems as a single system Which of the following service models would most likely be used to replace on premises servers with a could solution - Answer-IaaS - client moves whole infrastructure to the cloud minus the hardware of course which is always controlled by the CSP in cloud deployments Which of the following best mitigate a hackers frequent attempts at brute forceing A company's password - Answer-Two factor authentication, complex passwords. — passwords are best protected with longer, more complex passwords preferably pass phrases made up of multiple words. Additionally some form of MFA is considered essential today for "password security". Multi factor authentication protects your password by preventing it from being a single point of failure now we should require another factor in addition to our password such as using a biometrics or a smart card After configuring new firewalls with the correct configuration to be deployed to each remote branch, unneeded services were disabled, and all firewalls rules were applied successfully. Which of the following actions should be performed next to finish hardening the firewalls? - Answer-Update the firewalls with current firmware and software — Keeping a device up today is an essential step in hardening any system Which of the following solutions would allow for high speed, low latency, and globally disperse content distribution? - Answer-Public cloud — CDNs or content delivery networks are load balance networks that are geographically separated in order to provide the best connection for local users while also providing normal load balancing services. This is just the idea of having many servers all around the world to serve many people A new network was set up in order to facilitate more users in a building near your companies HQ. The new network is connected to the HQ's LAN via a fiber optic cable. However many users on the new network are unable to access the companies Intranet despise being able to access the Internet. Which ofthe following corrections would most likely resolve this issue? - Answer-Correct the external firewall gateway address — Could be a misconfigured firewall Which of the following attacks consists of following closely behind a real employee into a secure building by grabbing the door without their knowledge? - Answer-Tailgating — Is the act of following somebody into a secure area without their knowledge Piggybacking is following somebody into a secure area with their knowledge IP headers would be found under which of the following OSI layers? - Answer-Layer 3- routers, IPv4 , IPv6, and ICMP Which of the following solutions would provide redundancy for a server if our main concern is physical port failure - Answer-NIC teaming — Utilizing multiple physical network cards/ethernet ports in order to connect to the network. This would allow one to physically fail while keeping network connectivity Which of the following is the largest MTU for a standard ethernet frame - Answer-1500 Which of the following TCP ports is used by the windows OS for file sharing - Answer-445- NetBIOS/SMB ( sharing files/access) Which of the following subnet mask's is the equivalent of a CIDR of /20? - Answer-255.255.240.0. - /20 A large amount of expensive equipment is being moved into a company warehouse this equipment needs to be tracked when it leaves or enters the warehouse or when it is taken to be serviced which of the following solutions would best allow us to record these changes - Answer-Asset tags— Asset tags are great for tracking inventory of any type.
